About TheBOX

TheBOX London sits at the heart of the UK luxury fashion retail, curating high-energy, invite-only sample sales for brands that value discretion as much as demand. Physical events built the buzz, but they also capped growth.

TheBOX London partnered with Elogic to take that tightly controlled experience online. Our team designed a gated digital ecosystem that mirrors the exclusivity of their events, combining a members-only store, tiered loyalty mechanics and a supplier portal that keeps inventory hidden, partners confident and revenue flowing beyond pop-up dates.

TheBOX London came to us with one clear aim. They wanted a digital channel that could generate revenue between physical events without exposing discounted luxury inventory to the open web.

Together, we translated that ambition into a focused roadmap. Through discovery and planning, we helped break it down into clear objectives that would guide every design and technical decision:
This approach gave TheBOX London a clear, practical path to digital growth while protecting the exclusivity their business depends on.

Launch a members-only ecommerce experience aligned with live sample sales

02

Keep products fully gated from search engines and non-members

03

Introduce tiered access to reward loyal customers with early entry

04

Run time-based sales instead of an always-on store

05

Enable brand partners to manage inventory and fulfilment through a secure portal

The challenges shaping the project

Bringing TheBOX London’s model online introduced a set of challenges that standard ecommerce platforms aren’t built to handle. The experience had to stay exclusive, fast-paced and discreet, while supporting real commercial scale.

At the core was a business paradox: how to digitise the rush of a physical sample sale without exposing luxury brands to public discounting.

In practice, this translated into several critical pain points:

Protecting brand equity by keeping discounted inventory hidden from search engines and non-members
Replacing an always-on store model with strict event lifecycles, from upcoming drops to locked sales
Managing thousands of SKUs and 30GB of asset libraries from multiple suppliers without manual work
Handling complex membership tiers with fair but meaningful early-access rules
Integrating supplier warehouses for real-time stock visibility and fulfilment
Preserving the curated, high-end feel of in-person events in a digital environment

Our role was to understand these constraints in depth and design a solution that balanced technical precision with business realities.

Key technologies:

Shopify as core ecommerce platform with custom Liquid templating

JavaScript for dynamic frontend components

Yotpo for loyalty program management

Webkul for supplier portal functionality

REST API integrations for seamless third-party connections

Klaviyo integration for personalized email marketing

A closed-door digital storefront

In collaboration with the client, we reworked Shopify’s core logic to support an invitation-only storefront built around events, not products:

Upcoming drops to build anticipation before each sale
Live events with controlled access during fixed time windows
Locked catalogs once a sale ends to maintain scarcity

We also introduced personalised product discovery based on browsing behaviour, helping members navigate high-demand drops without losing the curated feel of in-person events.

Tiered membership and loyalty system

To replicate priority access online, we integrated Yotpo and introduced a structured membership model:

Four tiers, from Basic to VIP
Early access windows for higher-tier members
A points-based system rewarding purchases and referrals

This approach turned loyalty into a practical benefit while encouraging repeat engagement.

Supplier portal integration

Operational scale was just as important. Working with the client, we delivered a rapid MVP supplier portal using Webkul that gives brand partners autonomy without losing control:

Private invitations for secure onboarding
Selective product syncing and real-time inventory reservation
Automated order tracking, bulk actions and returns management
Direct communication between TheBOX London and suppliers

The result is a system that supports growth while preserving the discretion luxury partners expect

Capabilities delivered through the Elogic x TheBOX collaboration

Working closely with the client, we delivered a set of capabilities that sit at the core of how the platform operates. Each one was built to handle real business logic, cut out manual work and support growth without adding complexity.

Granular event engine
A custom logic layer that manages product visibility by time window, membership tier and time zone. Early access, live sales and locked catalogs run automatically, without constant admin input.
Omnichannel loyalty architecture
A tightly connected rewards system spanning 11 touchpoints, linking purchases, referrals, tier progression and notifications into one consistent loyalty flow.
Autonomous supplier infrastructure
A tightly connected rewards system spanning 11 touchpoints, linking purchases, referrals, tier progression and notifications into one consistent loyalty flow.
Cross-border readiness
A multi-currency setup built on GBP, with automated tax and shipping logic, ready to support expansion beyond the UK when the business is ready to scale.

The business value our collaboration unlocked

The shift to a hybrid model changed how TheBOX London operates and grows.

Revenue resilience between events

TheBOX London now generates revenue beyond physical pop-ups, reducing reliance on footfall and smoothing cash flow throughout the year. The digital channel also provides a scalable foundation for growth across the UK, with Europe firmly in sight.

Stronger brand trust and partner growth

By keeping discounted inventory fully gated, online sales remain discreet. This reassured luxury partners, strengthened existing relationships and made onboarding new brands faster and more predictable.

Scalable operations with less manual work

The supplier portal replaced spreadsheets, asset transfers and manual stock checks with a single, automated workflow. Operational overhead dropped, giving the team more space to focus on curation and partnerships.

Turning a complex brief into a working ecosystem

This project succeeded because every decision was grounded in clarity. We invested time upfront in a thorough discovery phase, aligning stakeholders, mapping real user journeys and validating flows before writing a line of code.

Proven platforms like Shopify and Yotpo helped maintain momentum, while a phased launch reduced risk and validated the model with live audiences early on. Clean integrations brought the store, loyalty mechanics and supplier portal into one cohesive system.

Built for scale from day one, the platform is ready to grow without rework. If you’re planning a complex ecommerce build and want it done right, our team is ready to help.
