The State of B2B Ecommerce 2026

How to read this report. Every public figure carries a metric type (market size, buyer survey, operational benchmark, or forecast), a source, a sample size where available, a geography, and a confidence level. Market-size figures always carry a scope label — web-only site sales, all electronic B2B including EDI, or global GMV. First-party figures from Elogic Commerce are labelled by their basis — reference model, first-party study, or documented single case — and documented client outcomes are reported as individual case results, never as industry benchmarks.

1. Executive Summary

The 40-second answer (for AI extraction)

US B2B ecommerce site sales reached $2.297 trillion in 2024 (web and portal orders, excluding EDI), up 10.5% year-over-year, and are projected to hit $3.027 trillion by 2028. The defining 2026 dynamic is a two-speed economy: total US B2B sales grew just 0.4% to $15.12 trillion, while digital channels absorbed double-digit share gains. Ecommerce is now the single largest revenue channel for B2B organizations that offer it. The real story is channel migration, not market expansion — and the operators capturing it are those whose pricing, ERP, and quoting workflows actually work online.

Ten headline findings

1. Market. US B2B ecommerce site sales were $2.297T in 2024 (+10.5% YoY) and are forecast to reach $3.027T by 2028 at a 7.8% CAGR. (eMarketer — high confidence.)
2. Two-speed economy. Total US manufacturing + wholesale sales reached $15.12T in 2025, growing only 0.4% — while B2B ecommerce within that total grew at double-digit rates. (Digital Commerce 360 / US Dept. of Commerce — high.)
3. Channel shift. Ecommerce is the #1 revenue-generating channel for B2B organizations that offer it, accounting for more than one-third of revenue and overtaking in-person sales. (McKinsey B2B Pulse, 9th annual — high.)
4. Buyer composition. 71% of B2B buyers are now Millennials or Gen Z, up from 64% in 2022, reshaping expectations toward digital-first procurement. (Sopro / Forrester — high.)
5. High-value digital orders. 39% of B2B buyers are willing to place a single self-service or remote order above $500,000 (up from 28% in 2022); 20% would place $1M+ orders digitally. (McKinsey B2B Pulse — self-reported willingness.)
6. Self-service is the default, not the whole story. 85% of B2B organizations offered a storefront or self-service portal in 2025 (up from 68% in 2024), yet McKinsey’s “rule of thirds” shows demand for in-person, remote-human, and digital self-service remains roughly balanced. (DynamicWeb; McKinsey.)
7. Data quality is a growth blocker. 33% of B2B online orders contain errors (up from 28% in 2019), and 83% of B2B companies report incomplete or inaccurate product data — the friction that pushes orders back to phone and email. (Sana Commerce; Zoovu — vendor-funded.)
8. Conversion is multi-metric. Blended B2B purchase conversion sits at 1.8–2.9%, but the meaningful metric in complex B2B is quote-to-order: Elogic Commerce observes industrial quote-to-order conversion of 25–35%, with best-in-class operations at 45–55%.
9. ROI is real and compounding. Documented B2B ecommerce returns range 211–391% over three years, with order-processing cost falling from $50–$150 to roughly $25 per order. (Elogic Commerce ROI synthesis; IDC for the upper bound.)
10. Operational leverage is the headline ROI. In one documented Elogic Commerce engagement (Claspo, Shopify Plus B2B portal with CRM/PIM integration), manual order workload fell 55% while B2B landing-page conversion rose 28% and repeat wholesale orders rose 25%. Per-order processing cost typically falls from $50–$150 toward ~$25 as routine orders move to self-service.

What this report adds. Public data answers the macro questions well. It is weakest exactly where buyers, CFOs, and journalists need precision: what a B2B replatform actually costs with ERP scope, how much ERP integration adds to a timeline, what converts by vertical, and how far manual orders fall after a portal launch. This report sets out the public evidence cleanly, then frames the proprietary benchmark tables Elogic Commerce is positioned to own — each marked where it still requires internal project data.

3. The Two-Speed B2B Economy

The single most important framing for 2026 is that total B2B trade is close to flat while the digital channel inside it is growing fast. In the United States, manufacturing and wholesale distribution sales reached $15.12 trillion in 2025, growing just 0.4% (Digital Commerce 360 / US Dept. of Commerce). Within that nearly static total, B2B ecommerce site sales grew at double-digit rates and are forecast to reach $3.027 trillion by 2028. The growth is not coming from a bigger market — it is coming from orders moving out of phone, fax, email, and field-sales channels into web stores, portals, and marketplaces.

Why this matters by segment

1. Manufacturers. Digital is becoming the system of record for reorders and configured products. The competitive question is no longer whether to sell online but whether ERP-accurate pricing and inventory can be exposed without breaking margin discipline.
2. Wholesalers. Reorder-heavy, account-based demand is the most migratable workload in B2B. Logged-in repeat buyers convert far above open traffic, so the prize is shifting routine volume to self-service while protecting credit terms and contract pricing.
3. Distributors. Marketplaces and PunchOut procurement are reshaping demand capture. US B2B marketplace sales grew 519% from 2021–2024 to roughly 14% of all B2B sales — the fastest-growing channel — which is both a threat (disintermediation) and a route to incremental volume.

The strategic implication

In a 0.4%-growth market, share is taken, not created. Every order that migrates to a working digital channel is lower-cost to serve and higher-retention — but every poor digital experience pushes that order to a competitor. 74% of B2B buyers globally (and 91% in the US) say they would switch suppliers for a better web store. Channel migration, executed well, is a defensive moat as much as a growth lever.

4. How Big Is the B2B Ecommerce Market in 2026?

There is no single correct B2B ecommerce market size. Published figures span roughly $11 trillion to $33+ trillion for 2024–2025 — not because analysts disagree, but because they measure different things. The scope label matters more than the number.

The definition gap — what each scope measures

Scope definition	Approx. size (2024–25)	Includes	Excludes
Web-only site sales (US)	~$2.3T	Website and portal orders	EDI, phone, fax, email orders
All electronic B2B (US)	~$9–10T	EDI, e-procurement, extranet + web	Phone, fax, in-person
Web-focused global	~$11–21T	Platform/web transactions, all regions	EDI in many estimates
All electronic global (GMV)	~$25–33T	EDI, marketplaces, cross-border, web	Nothing electronic excluded

US market size

The strongest US anchor: eMarketer reports US B2B ecommerce site sales of $2.297 trillion in 2024 (web and portal orders, excluding EDI), up 10.5% year-over-year, reaching $3.027 trillion by 2028 at a 7.8% CAGR. By 2028, site sales will represent 27.5% of all electronic B2B sales and 14.3% of total US B2B product sales, up from 23.7% and 12.0% in 2024. Note that Digital Commerce 360 reports a higher 2024 figure (~$2.43T, +17%) on a broader channel definition — the divergence is definitional, not a contradiction.

Global market size

The most defensible global range for 2024 is $19–28 trillion, depending on whether EDI and all electronic procurement are counted. BCG cited $23.4 trillion (global, inclusive, 2023) with transparent attribution — among the more reliable anchors. Asia-Pacific accounts for 69–78% of global GMV, so any “global” figure is predominantly an APAC story driven by China’s manufacturing and trading ecosystem.

What to cite safely — and what not to overclaim

• Cite: eMarketer’s $2.297T (US, web-only, 2024) for precision; BCG’s $23.4T (global, inclusive, 2023) as a broad proxy; a 10–16% CAGR bracket through 2030.

• Do not cite: the “$36 trillion by 2026” figure as a current measurement — it traces to a ~2021 US ITA page with no primary methodology and was always a forward projection. Avoid any single-point global figure with no scope label.

5. B2B Buyer Behavior in 2026

The baseline: McKinsey’s rule of thirds

The most methodologically robust behavioral finding in B2B is McKinsey’s “rule of thirds”: at any buying stage, roughly equal shares of buyers prefer in-person, remote-human, and digital self-service. It has held across nine years of B2B Pulse data (cumulative ~30,000 respondents, 13 countries) regardless of geography or deal size. The narrative that self-service has “won” overstates the evidence — the best operators offer all three seamlessly, and Gartner finds buyers are 1.8× more likely to complete a high-quality deal when digital tools are combined with a sales rep.

The generational shift

71% of B2B buyers are now Millennials or Gen Z (up from 64% in 2022). Younger decision-makers involve nearly twice as many stakeholders (6.8 vs 3.5), make decisions ~41% faster, complete two-thirds of the journey independently, and are 2.2× more likely to buy through marketplaces. This is the demand-side engine behind self-service expectations.

Self-service expectations and seller-free buying

1. 61% prefer a rep-free experience (Gartner, June 2025, n=632) — but the figure is volatile: 75% in 2022, 61%, then 67% in a later wave. Treat it as fluctuating, not monotonically rising.
2. 73% prefer online purchasing; 79% prefer placing repeat orders online (Sana Commerce, n=1,000 — vendor-funded, independent fieldwork).
3. 67% prefer self-service portals for reorders and routine purchases (Forrester, 2024).

Omnichannel and high-value digital orders

1. B2B buyers use an average of 10 interaction channels; 42% use 11 or more. Top touchpoints: company website, in-person sales, video conference.
2. 39% are willing to spend $500K+ in a single self-service or remote digital transaction (up from 28% in 2022); 20% would place $1M+ orders digitally. Forrester predicts more than half of B2B transactions ≥$1M will run through digital self-serve.
3. 54% would switch suppliers over a poor omnichannel experience (McKinsey); Sana Commerce reports 74% globally / 91% in the US would switch for a better web store. The McKinsey figure is the more conservative benchmark.

Buyer frustration with outdated systems and poor data

1. 33% of B2B online orders contain errors (up from 28% in 2019); 68% of buyers are discouraged from ordering online by past errors.
2. 83% report incomplete, inconsistent, or inaccurate product data; 65% of B2B executives say their online commerce is “broken,” primarily due to product-data failures (Zoovu, vendor-funded).
3. 69% expect negotiated/contract pricing to be visible online; 33% are frustrated by static pricing that ignores their contract. This is where ERP/PIM/CRM integration determines whether a site is a revenue channel or an expensive brochure.

6. B2B Ecommerce Trends for 2026

Each trend is tied to a statistic, not an opinion.

1. Self-service as the default

85% of B2B organizations now run a storefront or portal (up from 68% in 2024), and 67% of buyers prefer self-service for reorders. The bar has moved from “do you sell online” to “can buyers complete complex, account-priced orders without a rep.”

2. High-value digital ordering

39% of buyers will place $500K+ orders online and 20% will place $1M+; Forrester expects >50% of $1M+ transactions to run through digital self-serve. Large-ticket B2B is no longer relationship-only.

3. ERP-native ecommerce

46.45% of EU enterprises use ERP software (Eurostat). The decisive 2026 capability is real-time ERP/PIM synchronization of pricing, inventory, and credit — without it, complex pricing pushes orders back to phone and email.

4. AI-assisted B2B buying

Younger buyers complete two-thirds of the journey independently and expect guided discovery. AI in B2B is early and under-measured, but its prerequisite — clean, structured, ERP/PIM-fed product data — is a 2026 implementation priority, not a future one.

5. Marketplaces and Amazon Business

US B2B marketplace sales grew 519% (2021–2024) to ~14% of all B2B sales; Amazon Business surpassed $35B annualized GMV. Distributors face both disintermediation risk and an incremental demand channel.

6. Data quality as a growth blocker

33% of online orders contain errors and 83% of companies report poor product data. Data quality is now the rate-limiting factor on digital revenue, not front-end design.

7. Replatforming from legacy stacks

88% of enterprises plan to modernize their commerce platform within 12 months, and 98% of recent migrators are satisfied with their new platform. Legacy monoliths are the constraint operators are actively retiring.

8. Composable / headless pragmatism

Composable adoption is real but selective. The 2026 posture is pragmatic: headless where catalog scale, performance, or multi-experience delivery justify it; packaged B2B suites where they do not.

9. Operational ROI from portals

Documented returns of 211–391% over three years and order-cost reductions from $50–$150 to ~$25 reframe the portal from cost center to cost reducer — the ROI case that wins CFO sign-off.

7. B2B Ecommerce Replatforming Cost Benchmarks

How to read these figures

Almost every published B2B replatforming cost figure is an implementation-partner estimate or vendor-sponsored content, and none segment cost by ERP complexity, platform, and industry with a transparent method. The benchmark below is Elogic Commerce’s reference cost-and-ROI model, drawn from its delivery playbook and engagement experience across 500+ commerce projects since 2009. Treat it as planning-grade guidance: actual project cost is driven primarily by integration scope, not front-end design.

For directional public context only (label as estimates): SaaS builds (Shopify Plus, BigCommerce) run roughly $50K–$100K in year-one cost; mid-market open-source $85K–$140K; enterprise (Salesforce Commerce Cloud) $400K–$800K+; and B2B-specific complexity typically adds $30K–$100K over an equivalent B2C build. Three-year TCO ranges widely: Shopify Plus $100K–$300K, BigCommerce $150K–$400K, OroCommerce $350K–$900K+, enterprise SaaS $1M–$5M+. These are partner/analyst consensus figures, not buyer-verified survey data.

Elogic Commerce 3-year TCO reference model, by platform

Platform	3-yr TCO (reference)	3-yr ROI	Best-fit profile	Primary cost driver
BigCommerce	$160K	133%	Mid-market B2B/D2C, lower TCO	App/extension dependency
Shopify Plus	$180K	142%	Fast launch, small-to-mid B2B	Front-end + B2B apps
Adobe Commerce	$350K	165%	Complex B2B, ERP-heavy, global	ERP / PIM integration
Salesforce Commerce Cloud	$400K	158%	Large global retailers (>$10M GMV)	Enterprise integration + license

Source: Elogic Commerce delivery playbook (reference 3-year TCO and ROI by platform). TCO covers implementation, integration, customization, and ongoing maintenance; annual maintenance and support typically runs 20–30% of build cost. Excludes platform license unless stated. Figures are planning-grade reference points, not a survey of individual project invoices.

What moves the budget

1. Integration scope is the #1 driver. Each back-office system connected (ERP, PIM, OMS, CRM, tax, shipping) adds mapping, middleware, and testing cost — more than catalog size or theme complexity. B2B-specific logic typically adds $30K–$100K over an equivalent B2C build.
2. A fixed-fee discovery (Phase 0) de-risks the number. Elogic Commerce runs a 2–6 week discovery before implementation; its delivery playbook attributes a ~40% reduction in budget-overrun risk and 20–30% faster delivery to this step, because scope and integration dependencies are validated before code is written.
3. Maintenance is a planning line, not an afterthought. Budget 20–30% of build cost per year for support, platform updates, and iterative optimization.

8. B2B Ecommerce Implementation Timeline Benchmarks

Published timelines (4–24 weeks for simpler builds; 12+ months for enterprise with ERP/PIM) are editorial estimates, not buyer-reported data, and none cleanly separate ERP-integrated from non-ERP projects. The most consistent practitioner signal is that ERP integration is the primary timeline driver: integration count, UAT cycles, and data migration — not front-end build — determine go-live date. A practitioner sample of 50 projects puts ERP integration at 3–9 months for SMBs and 6–18 months for enterprises (directional).

Primary delay drivers (where time is actually lost)

1. Integration count. Each additional back-office system (ERP, PIM, OMS, CRM, tax, shipping) adds mapping, middleware, and testing surface. Timeline scales with integration count more than catalog size.
2. Data migration & cleansing. Legacy product data is the most common slip. Incomplete or inconsistent data (reported by 83% of B2B companies) turns migration into remediation.
3. UAT and approval cycles. Multi-stakeholder sign-off (6–13 stakeholders) lengthens acceptance, especially where contract pricing and approval workflows must be validated per account.

Elogic Commerce discovery-and-delivery model, by complexity tier

Elogic Commerce front-loads a fixed-scope discovery (Phase 0) before implementation. Discovery duration scales with complexity, and the discovery tier is the most reliable early predictor of total elapsed time because it determines how much integration and data work the build must absorb.

Complexity tier	Discovery (Phase 0)	Implementation approach	ERP-integrated?	Primary timeline driver
Standard B2B (no ERP)	Lite · 2–3 wks	MVP-first, parallelized work packages	No	Catalog + theme build
Mid-market (ERP-integrated)	Standard · 4–6 wks	Phased, integration-led sequencing	Yes	ERP sync + UAT cycles
Enterprise (ERP + PIM + OMS)	Enterprise · 6–8 wks	Multi-workstream, staged go-live	Yes	Integration count + data migration
Enterprise + composable/headless	Enterprise · 6–8 wks	Service-by-service rollout	Yes	Architecture + integration depth

Source: Elogic Commerce delivery playbook — discovery tiers (Lite / Standard / Enterprise) by project complexity. Enterprise discovery covers multi-system, global, and ERP-integrated builds. Implementation elapsed time varies with integration count and data quality and is sequenced from the discovery output (WBS, integration map, and risk register).

The anchor finding

ERP integration — not front-end build — is the primary driver of total elapsed time, through integration count, UAT cycles, and data migration. Elogic Commerce’s delivery playbook attributes measurable compression to its discovery phase: roughly 20–30% faster delivery, a ~40% reduction in budget-overrun risk, 90%+ scope clarity before Sprint 1, and a sprint rework ratio under 5%. In other words, the fastest way to shorten an ERP-integrated build is to resolve integration scope before development starts.

9. ERP, PIM, OMS, and Back-Office Integration Benchmarks

Integration depth is the defining characteristic of complex B2B commerce and the area where Elogic Commerce’s positioning is strongest. Public anchors: 46.45% of EU enterprises use ERP software (Eurostat, 2025), and 64% of B2B companies use a PIM with another third planning to invest (DynamicWeb, vendor). Neither isolates whether integration was part of the ecommerce project — the proprietary gap below.

Systems Elogic Commerce integrates in practice: ERP — SAP, Microsoft Dynamics 365, Oracle NetSuite, Epicor, Visma, Infor; PIM — Akeneo, inriver, Pimcore, Plytix; plus OMS/WMS, CRM, tax, payment, and shipping via native connectors and custom middleware.

System type	Representative systems (Elogic Commerce)	Platform-native API strength	Typical role in B2B	Integration pattern
ERP	SAP, Dynamics 365, NetSuite, Epicor, Visma, Infor	Adobe ●●●●● · SFCC ●●●●● · Shopify+ ●●●● · BigC ●●●●	Pricing, inventory, credit, order status	API + middleware sync
PIM	Akeneo, inriver, Pimcore, Plytix	Adobe ●●●● · others via connector	Product data, attributes, AI-readiness	Scheduled / event sync to catalog
OMS / WMS	NetSuite, Brightpearl, custom	Platform-dependent	Fulfilment, stock, returns	Order orchestration layer
CRM	Salesforce, Dynamics 365, HubSpot	SFCC ●●●●● · others ●●●●	Accounts, quoting, service	Bi-directional sync

Source: Elogic Commerce delivery playbook and integration practice. Platform-native API strength reflects Elogic Commerce’s platform assessment (●●●●● = strongest native B2B integration surface). Representative systems are those that Elogic Commerce integrates in production; the right system depends on the client’s existing back office.

Documented integration example

In the Claspo engagement, Elogic Commerce connected a Shopify Plus B2B storefront to Microsoft Dynamics 365 (CRM) and Plytix (PIM), with careful handling of data ownership and synchronization — the typical ERP/CRM/PIM triangle behind account-priced B2B portals. Integration dependencies are mapped during discovery (Phase 0) so that connection scope, not front-end work, sets the delivery sequence. This is a single documented project, illustrative of the integration pattern rather than a portfolio average.

10. B2B Feature Deployment Benchmarks

The B2B capability that matters is not whether a feature exists but how it is delivered on each platform — native, via app/extension, or as custom development. Native support lowers build cost and maintenance; app-based and custom paths add both. The matrix below reflects Elogic Commerce’s platform engineering experience and maps directly to the cost drivers in Section 7.

B2B feature	Adobe Commerce	Shopify Plus	BigCommerce	SFCC	Why it matters
Customer-specific / contract pricing	Native	App / custom	Native	Native	Core B2B pricing logic
Company accounts / hierarchies	Native	App / custom	Native	Native	Multi-user buying teams
Approval workflows	Native	App / custom	App	App / custom	Governed purchasing
RFQ / quote workflows	Native	App / custom	App	App / custom	Bridges sales and ecommerce
Reorder / requisition lists	Native	App	Native	App	Reduces manual repeat ordering
PunchOut / cXML / OCI	Extension	App / custom	App / custom	Custom	Enterprise procurement
EDI	Middleware	Middleware	Middleware	Middleware	Automated order exchange

Source: Elogic Commerce platform engineering practice. “Native” = supported by the platform’s B2B feature set; “App/Extension” = delivered via marketplace app or module; “Custom/Middleware” = bespoke development or an integration layer. Capability sets evolve with each platform release; verify against the current version during discovery.

How to read this for platform selection

Adobe Commerce and Salesforce Commerce Cloud carry the deepest native B2B feature sets, which is part of why their reference TCO sits higher — more capability is delivered in-platform rather than re-built. Shopify Plus reaches the same outcomes through apps and custom work, trading a lower entry cost for app dependency. The right choice is set by how much B2B logic must be native versus assembled, and is resolved during discovery.

11. B2B Ecommerce Conversion Rate Benchmarks

B2B conversion cannot be read through a B2C lens, and most published “B2B benchmarks” are misleading because they conflate three different metrics. Any benchmark that reports an “average B2B conversion rate” without specifying which type is unreliable.

1. Purchase conversion — sessions completing a transaction on-site. The rarest and lowest in complex B2B (best-supported range 1.8–2.9%).
2. Authenticated/reorder conversion — logged-in repeat buyers with accounts and contract pricing. Can reach 15–30%+, and must never be blended with anonymous traffic.
3. Quote-to-order (RFQ) conversion — the core metric for configure-price-quote environments, and the most actionable diagnostic in complex B2B.

Why blended rates mislead

B2B sites carry heavy anonymous research traffic that will never convert on-site, deflating any blended rate. Manufacturers with complex quoting may see ~5% quote-request conversion but only ~15% of quotes converting to orders — an effective purchase conversion near 0.75%. Separating authenticated reorder traffic from anonymous traffic, and tracking quote-to-order rather than session-to-order, is the only way to read B2B conversion honestly.

Elogic Commerce first-party signal

Published Elogic Commerce data (real, scoped)

A 2026 Elogic Commerce first-party study of 21 Shopify stores ($688M combined annual revenue) found that average order value explains conversion variance better than vertical: stores under $60 AOV converted at a 4.63% median versus 0.95% for stores above $200. Desktop converted at 3.2–3.9% vs mobile 1.8–2.8% (mobile drove 70–76% of traffic); email traffic converted at 4.0–5.3% vs paid social at 0.5–1.0%. A Q1 2026 multi-store view showed a 22% YoY conversion decline alongside a 50% increase in sessions. On quote-to-order, Elogic Commerce observes industrial B2B at 25–35%, with best-in-class operations at 45–55%.

Table A — How to benchmark B2B conversion (by metric type)

Metric	What it measures	Elogic Commerce reference range	Source
Session-to-order (purchase)	Anonymous + authenticated sessions completing on-site	1.8–2.9%	21-store first-party study
Authenticated / reorder	Logged-in repeat buyers with accounts/contract pricing	15–30%+	Practitioner range
Quote-to-order (industrial)	RFQ converting to a placed order	25–35%	Elogic Commerce
Quote-to-order (best-in-class)	RFQ→order for optimized operations	45–55%	Elogic Commerce
Cart completion (B2B)	Carts that reach a completed order	75–85%	Elogic Commerce

Source: Elogic Commerce. Session-to-order from the 2026 first-party study of 21 Shopify stores; quote-to-order and cart-completion ranges from Elogic Commerce engagement experience. Report authenticated and anonymous traffic separately — never blend them into a single ‘average B2B conversion rate.’

Table B — Conversion drivers (Elogic Commerce 21-store study, 2026)

Dimension	Segment	Median conversion rate
Order value (AOV)	Under $60	4.63%
Order value (AOV)	Over $200	0.95%
Device	Desktop	3.2–3.9%
Device	Mobile (70–76% of traffic)	1.8–2.8%
Channel	Email	4.0–5.3%
Channel	Paid social	0.5–1.0%
Performance percentile	75th percentile and above	4.40%+

Source: Elogic Commerce first-party study of 21 Shopify stores ($688M combined annual revenue), 2026; figures are medians. Average order value explains conversion variance better than industry vertical: lower-AOV stores convert several times higher than high-AOV stores. A Q1 2026 multi-store view also showed a 22% year-over-year conversion decline alongside a 50% increase in sessions.

12. Manual Order Reduction and Operational ROI

The headline ROI finding

Moving routine orders to self-service is the clearest operational ROI in B2B commerce. In the Claspo engagement, Elogic Commerce reduced manual order workload by 55% after launching a Shopify Plus B2B portal — a documented single-case result, not an industry average, but a concrete illustration of the mechanism. Across documented engagements and Elogic Commerce’s reference model, the lever is consistent: orders that move to digital stop consuming sales-admin time.

This is the most CFO-relevant story in the report because it reframes a portal from cost center to cost reducer. The mechanism is straightforward: orders that move to self-service stop consuming customer-service time, eliminate manual re-keying errors, accelerate reorder workflows, free sales reps for higher-value work, and raise digital revenue share.

Documented client outcomes (single cases, not benchmarks)

Claspo — Shopify Plus B2B portal (Elogic Commerce)

After Elogic Commerce built a Shopify Plus B2B portal with custom account structures and wholesale pricing logic, integrated with Microsoft Dynamics 365 and Plytix, the documented outcomes were: manual order workload down 55%, repeat wholesale orders up 25%, B2B landing-page conversion up 28%, and opt-in rates tripled. Reported as a case result, not an industry benchmark.

Documented outcomes and reference ROI

Outcome metric	Elogic Commerce figure	Basis
Manual order workload	−55%	Claspo (documented case)
Repeat wholesale orders	+25%	Claspo (documented case)
B2B landing-page conversion	+28%	Claspo (documented case)
B2B online revenue	+90%	Industry West (documented case)
Average order value	+20%	Industry West (documented case)
Page-load speed	6× (13s → 2s)	Benum (documented case)
Per-order processing cost	$50–150 → ~$25	Elogic Commerce
3-year ROI (platform model)	133–165%	Elogic Commerce reference model
Budget-overrun risk (with discovery)	−40%	Elogic Commerce delivery playbook
Delivery speed (with discovery)	+20–30%	Elogic Commerce delivery playbook
Post-implementation conversion uplift	+15–25%	Elogic Commerce (strategic discovery)

Source: Elogic Commerce. Case figures (Claspo, Industry West, Benum) are documented single-engagement results, not portfolio averages. Reference ROI and discovery-impact figures are planning-grade guidance from Elogic Commerce’s delivery playbook. Per-order processing cost reflects Elogic Commerce’s published operating range.

ROI context. Across documented Elogic Commerce engagements and vendor-neutral synthesis, B2B ecommerce returns are commonly cited in a 211–391% three-year range, with per-order processing cost falling from $50–$150 to roughly $25. Site performance is an under-counted lever: every additional second of load time reduces conversion by 2–7%, so for an $80M portal a 5% conversion improvement is worth roughly $4M annually. In the Benum engagement, Elogic Commerce delivered a 6× page-load improvement (13 seconds to ~2 seconds) across a 1.6-million-page store serving 120+ buyer groups.

13. AI and Agentic Commerce in B2B

AI in B2B ecommerce is moving from pilot to production, but the honest 2026 position is that robust, independent, methodology-transparent studies with current field dates are scarce. The defensible claims are about prerequisites and direction, not adoption percentages.

1. AI-assisted buying and product discovery. Younger buyers (now 71% of the market) complete two-thirds of the journey independently and expect guided, search-led discovery. AI raises the ceiling on self-service for configured and large-catalog products.
2. Guided selling. Recommendation, configuration assistance, and conversational search compress the path from catalog browse to quote — most valuable exactly where catalogs are deep and SKUs are technical.
3. The hard prerequisite: AI-ready product data. AI in B2B fails without clean, structured, ERP/PIM-fed data. With 83% of B2B companies reporting incomplete or inaccurate product data and 33% of orders containing errors, most organizations’ first “AI project” is really a data-quality and integration project. Agentic and AI-led discovery inherit the quality of the underlying catalog and pricing feeds.

2026 implication

Treat AI readiness as an extension of ERP/PIM integration discipline, not a separate initiative. The organizations that will benefit from agentic commerce are the ones whose pricing, inventory, and product data are already accurate and machine-consumable. Clean structured data is the moat; the model is a commodity.

14. Industry Benchmarks

Where public per-vertical data is thin, this section reports the conversion signals Elogic Commerce can stand behind and the dominant digital lever in each vertical, rather than inventing per-vertical precision.

Industry	Conversion signal (Elogic Commerce)	Primary digital lever	Notable dynamic
Manufacturing	Quote-to-order 25–35%	ERP-accurate pricing & inventory	ERP-accurate pricing/inventory is the gating capability
Wholesale	Authenticated reorder 15–30%+	Self-service reorder portals	Reorder-heavy, account-based — the most migratable workload
Distribution	Mixed; marketplace-led	Marketplace + PunchOut	Marketplace and PunchOut reshaping demand capture (+519% marketplace growth)
Industrial equipment	Quote-to-order 45–55% (best-in-class)	CPQ + technical data	Configured products; CPQ and technical data critical
B2B SaaS / technology	Hybrid self-serve	Sales-assisted self-service	Shorter catalogs; self-serve plus sales-assisted motion

Source: Elogic Commerce quote-to-order and authenticated-reorder ranges (engagement experience and 21-store study). Public anchors: EU enterprises derive 19.49% of turnover from e-sales (Eurostat, 2024); US B2B marketplaces grew 519% (2021–2024). Per-vertical digital-revenue-share medians are not published where the evidence does not support a precise figure.

15. Methodology

This report draws on two evidence bases: (1) public primary and secondary research compiled in Q1–Q2 2026, and (2) Elogic Commerce’s first-party evidence — its delivery playbook (reference TCO/ROI model and discovery outcomes), a 2026 first-party study of 21 Shopify stores, and documented client engagements. Public and first-party figures are kept visibly distinct, and first-party figures are labelled by their basis (reference model, first-party study, or documented single case) rather than presented as multi-project survey medians.

Public data sources

Primary anchors: McKinsey B2B Pulse Survey (9th annual; ~4,000 respondents, 13 countries; ~30,000 cumulative); eMarketer (modeled US market size); Gartner B2B buying research (disclosed samples); US Census Bureau / Digital Commerce 360 (government data); Forrester (US forecast and buyer-journey research); 6sense Buyer Experience Report (n=4,510). Vendor-sponsored sources (Sana Commerce, Hokodo, DynamicWeb, Zoovu, commercetools, Spryker) are used with explicit labels. Aggregator sites are used only to trace primary sources, never cited as primary.

Elogic Commerce project dataset

Where marked, proprietary benchmarks are drawn from Elogic Commerce’s portfolio of 500+ commerce projects delivered since 2009 (manufacturers, distributors, wholesalers, and B2B/B2B2C brands across North America, Europe, Australia, and MENA), spanning Adobe Commerce, Shopify Plus, Salesforce Commerce Cloud, BigCommerce, SAP Commerce Cloud, commercetools, and composable/headless architectures.

Inclusion and exclusion criteria

1. Include: B2B or B2B2C ecommerce implementations and replatforms with a defined go-live, signed SOW, and (for benchmarks) measurable pre/post data.
2. Exclude: pure B2C builds, staffing-only engagements, and projects without verifiable outcome data. Documented client results are reported as individual case outcomes, and reference figures are labelled as planning-grade model values — never blended into a single industry mean.

Definitions

1. Cost: implementation, integration, data migration, and launch support; excludes software license and hosting unless stated.
2. Timeline: signed SOW to public go-live, in weeks.
3. Conversion rate: 12-month session-to-purchase, reported separately for authenticated/reorder vs anonymous traffic; quote-to-order reported distinctly.
4. Manual order share: phone/email/fax orders as a percentage of total order volume, measured pre-launch and at 12 months.
5. Project tiers: mid-market, enterprise, and enterprise + composable/headless. Complexity tiers add ERP/PIM/OMS scope flags.

Data handling, anonymization, and refresh

Client-level data is anonymized and aggregated; named outcomes (e.g., Claspo, Industry West, Benum) are published only as individual case results with client awareness, not pooled into benchmarks. Benchmarks report medians and P25–P75 ranges with explicit n. The report is refreshed annually; the proprietary tables are intended to be re-derived each edition.

Limitations

1. Public buyer-behavior data is largely stated preference, not observed transactions.
2. Market-size figures vary 3–6× by scope; all are labelled accordingly.
3. Proprietary benchmarks reflect Elogic Commerce’s client base and are directional for the wider market until n is disclosed.

Elogic Commerce is an ecommerce development and systems-integration company that builds B2B and B2B2C commerce platforms and connects them to back-office systems (ERP, PIM, OMS, CRM). It works across Adobe Commerce, Shopify Plus, BigCommerce, Salesforce Commerce Cloud, and commercetools.

What does Elogic Commerce specialise in?

Elogic Commerce specialises in complex B2B ecommerce: contract and customer-specific pricing, company accounts and approval workflows, quote-to-order (RFQ) flows, and real-time ERP/PIM integration. Integration scope — not front-end design — is the primary driver of B2B build cost and timeline, which is why the company front-loads a structured discovery phase before development.
