Top 5 Integrations Every Online Store Needs

Running an online store is tough when your systems don’t sync. Missed orders, outdated stock, slow checkouts… A lot can go wrong when CRM ecommerce tools, ERP integration, payment gateway integration, and shipping module integration setups aren’t working together.

This article gives you a clear, practical look at the ecommerce integrations that actually matter. You’ll learn what each one does, why it impacts performance, and how to choose the right setup for a store that runs smoothly at any scale.

What are ecommerce integrations

Ecommerce integrations are the connections that link your online store to the external tools it depends on—payment gateways, shipping carriers, CRM ecommerce platforms, ERP integration systems, marketing apps, accounting software, and more. 

These links use API integration or ecommerce plugins to keep data moving between systems in real time, so your store can operate without constant manual updates or copy-pasting.
Their role is to keep information accurate, reduce admin work, and ensure every tool in your setup works from the same source of truth. With thoughtful solution architecture, these connections stay reliable as your store grows or adds new software.

5 key types of ecommerce integrations

Once you understand what ecommerce integrations actually are, the next step is figuring out which ones matter most to your business. 

Not every store needs a dozen apps running in the background, but every store does need a solid foundation of tools that support daily operations, keep customers happy, and prevent the kind of chaos that usually creeps in as sales grow.

Below are the five categories that form that foundation. Each one solves a different operational challenge, and together they create a steady flow of information across your ecommerce ecosystem so you’re not stuck juggling fragmented tools or chasing missing data.

CRM integrations

CRM integrations connect your store to platforms that organize customer information in a single, structured place. When your ecommerce system syncs with a CRM, details that normally sit in separate tools—orders, messages, and browsing activity—flow into one profile without any manual effort.

This gives your team immediate clarity on who they’re speaking to, what each customer has done, and how to tailor communication that actually resonates. The CRM handles updates automatically, so your staff isn’t maintaining records by hand or trying to recreate segments from scratch.

Some of the most common examples of CRM ecommerce integrations are:

• HubSpot: Centralizes contacts, marketing automation, and sales activity
• Salesforce: Offers advanced customization, reporting, and enterprise-level customer management

Stores benefit from this ecommerce integration most when they:

Need better visibility into customer behavior, rely on repeat purchases, or want to scale marketing automation without hiring a larger team.

ERP integrations

ERP integrations connect your online store to the systems that keep your operations running behind the scenes. These platforms coordinate inventory, purchasing, warehousing, and finance, and an ERP integration pulls all of that information together so your store and your internal teams are always working with the same data.

For business owners, this means fewer surprises. Stock counts adjust the moment an order comes in. Warehouse teams know exactly what’s available before picking and packing. Financial reports reflect real sales numbers, not estimates based on yesterday’s exports. 

As your catalog grows or your fulfillment setup becomes more complex, this integration keeps everything organized and predictable instead of scattered across disconnected spreadsheets.

Most common examples of ERP integrations for ecommerce platforms are:

• Odoo: Modular ERP covering inventory, finance, supply chain, and more
• SAP: Suited for high-volume companies with detailed operational requirements
• NetSuite: Cloud-based ERP with strong financial and inventory management

Stores benefit from this ecommerce integration most when they:

Run large product catalogs, manage multiple fulfillment locations, or need reliable, real-time operational reporting.

Payment gateway integrations

Every online store exists for one core reason: to sell products. Sales only happen when customers can pay quickly and without second-guessing the checkout. That’s why payment gateway integrations are essential. They connect your store to secure services that authorize payments and keep sensitive details protected.

These integrations slide neatly into your ecommerce platform—whether you rely on Shopify integrations, Magento extensions, or another setup—so transaction data moves directly into your storefront, accounting system, and financial reports. 

Beyond processing payments, they help cut down on fraud attempts, keep the checkout experience steady, and sync financial details across your tools. A smoother, more flexible payment flow leads to higher conversion rates and far fewer reconciliation issues for your team.

The most wide-spread payment gateway integrations for ecommerce platforms are:

• Stripe: Flexible, developer-friendly payments with subscription support
• PayPal: Widely trusted digital wallet for quick checkout
• Adyen: Enterprise payment platform supporting global methods

Stores benefit from this ecommerce integration most when they:

Sell internationally, run subscription models, or want to reduce checkout abandonment.

Logistics and shipping modules integration

After a customer completes checkout, the focus shifts to getting the order shipped without delays. 

Logistics and shipping integrations make that possible by linking your store to the systems that handle fulfillment tasks: shipping rates, label creation, and tracking updates. Instead of entering details into separate portals or copying information from one tool to another, everything moves through a single, connected workflow.

With this setup, orders are processed faster and with fewer mistakes. Labels are generated automatically, tracking details reach customers without extra steps, and inventory updates as items leave your warehouse.

Some of the best logistics and shipping modules are:

• ShipStation: Centralizes shipments across multiple carriers
• DHL: Strong international logistics and cross-border delivery
• UPS: Reliable domestic and global parcel service

Stores benefit from this ecommerce integration most when they:

Ship daily, coordinate with multiple carriers, or need dependable visibility across the entire fulfillment process.

Marketing ecommerce integrations

Once orders are on their way, the next priority is keeping customers engaged so they come back. Marketing integrations help with that by connecting your store to email, SMS, and social media platforms, using real-time ecommerce data to guide communication. Instead of relying on guesswork, these tools respond to what customers actually do: browse, buy, or pause before checkout.

This leads to well-timed outreach across all your channels. Abandoned cart messages reach shoppers when they’re most likely to return, product suggestions reflect what’s genuinely available, and social ads stay aligned with your current catalog. You also get clearer insight into which touchpoints drive sales, while customers receive messages that feel relevant rather than generic.

Depending on which marketing channels you rely on, the most common tools fall into three categories:

Email marketing tools:

• Klaviyo – Behavior-driven flows with deep ecommerce data sync
• Mailchimp – Accessible email campaigns with reliable segmentation
• Omnisend – Email and multichannel automation tailored for ecommerce

SMS marketing tools:

• Attentive – Targeted text campaigns tied to shopping activity
• Postscript – SMS built specifically for Shopify stores
• Yotpo SMSBump – Automated texts and compliance tools for growing brands

Social media marketing tools:

• Meta Commerce Manager – Catalog sync for Facebook and Instagram ads
• TikTok Shop – Shoppable video content directly inside TikTok
• Pinterest Product Catalogs – Dynamic product pins synced with your store

Stores benefit from this ecommerce integration most when they:

Rely on repeat business, want automated marketing that scales with growth, or need consistent messaging across multiple customer touchpoints.

Real-world examples of ecommerce integrations

The value of ecommerce integrations becomes clear when they’re applied to real operational challenges. Below are a few real-world examples of Elogic’s clients where our team used integrations to turn disconnected systems into reliable, scalable ecosystems.

Armacell

Armacell’s expansion into new regions highlighted a major gap: their ordering process ran on complex SAP logic, while product data lived in a separate PIM. Without tight integrations, every step—from pricing validation to inventory checks—required manual intervention.Our team connected Adobe Commerce with SAP S/4HANA and Armacell’s custom PIM, giving the portal live access to stock levels, attribute-rich product data, and approval workflows. With these systems finally speaking the same language, cross-regional ordering became faster and far more predictable.

Key ecommerce integration outcomes:

• ERP-aligned checkout with automated validation
• Real-time inventory across multiple warehouses
• PIM-driven product attributes synced into Adobe Commerce
• 40% reduction in manual processing and faster approvals

Pharmaciaty

Pharmaciaty needed a single ecosystem where ecommerce orders, prescriptions, vendor updates, insurer rules, and fulfillment data could flow without manual intervention.

We connected Adobe Commerce with insurance databases, prescription validation APIs, and TMS/WMS systems to ensure eligibility checks, pricing adjustments, and delivery tracking all happened in real time.

Key ecommerce integration outcomes:

• Automatic insurance and prescription verification
• Unified B2C/B2B order management across partners
• Integrated delivery tracking directly from logistics tools
• Consistent data flow for regulated products

Enzio Manufacturing

Enzio’s legacy store offered no reliable link between ecommerce operations and SAP ERP, causing inventory errors and lost orders.We replatformed to commercetools, introduced a microservices setup, and integrated SAP to synchronize products, availability, and orders instantly. We also added Algolia for API-based search that supports B2B buying patterns.

Integration results:

• Real-time ERP sync improving accuracy and order tracking
• API-first architecture reducing TCO
• Centralized product and customer data for clean operations

Benefits of automation and data flow

Integrations matter because they keep your entire ecommerce operation running without constant supervision. When systems stay in sync and information moves automatically, your team can focus on growth instead of correcting errors or chasing missing data.

Why ecommerce integrations are essential:

• Reliable data flow automation keeps product details, orders, customer records, and financials consistent across every system.
• Real-time sync prevents overselling, mismatched stock counts, and outdated pricing.
• Ecommerce automation reduces manual tasks so teams spend less time updating spreadsheets and more time on revenue-driving work.
• Cleaner operations emerge when tools—ERP, CRM, shipping, payments—share one source of truth.
• Faster fulfillment becomes possible when warehouse and shipping systems receive accurate information the moment an order is placed.
• Better customer experiences follow from timely messages, accurate stock, and dependable order updates.
• Scalable growth is easier to manage when new channels, regions, or tools can plug into a stable integration framework.
