Rapid launch of a customised B2B intranet shop and warehouse synchronisation

In 2024, B2B e-commerce companies saw a 41% increase in turnover. Some even achieved growth of over 50%. A private, password-protected B2B intranet shop, seamlessly connected to your logistics infrastructure, provides a personalised, high-quality experience for your customers. This guide provides a technical and operational framework for creating a private intranet store for your B2B customers, integrating your warehouse management. By unifying a secure customer portal and real-time warehouse data, you can build a powerful and scalable digital sales channel, strengthening your customer relationships and generating measurable growth.

A B2B portal without deep integration with the warehouse is just a digital facade. Operational excellence and customer trust are achieved through direct, automated data flow between your e-commerce platform and your warehouse management system (WMS). Digitising the supply chain can improve service levels by 15 to 30% and reduce logistics costs by 10 to 20% through better data visibility and system integration. This connection, usually provided by APIs, becomes the central nervous system of all your B2B operations. With improved inventory visibility and real-time data sharing,​ the TMS (Transport Management System) can reduce transport costs by 5 to 10%..

​ Stockouts cost retailers nearly a trillion pounds a year. Elimination of stockouts and overselling: Real-time bidirectional API calls ensure that the inventory displayed in your online shop accurately reflects the physical stock available in your warehouse, avoiding costly backorders.

Accelerated order processing: Implementing a warehouse management system can improve warehouse productivity by 10% to 15% and inventory accuracy by 20% to 30%. Approved orders are instantly transmitted to the WMS, triggering the picking, packing and shipping processes without manual intervention, significantly reducing order processing times.

Eliminate costly data entry errors: Automation removes human error when entering orders, avoiding mistakes in references, quantities and delivery addresses that lead to costly returns and customer dissatisfaction.

Build customer trust through transparency: giving customers access to accurate stock levels and real-time updates on their order status (directly from WMS events) builds the trust that is essential for long-lasting partnerships.

As detailed in our analysis explaining why integrating a WMS boosts sales, this level of integration is what distinguishes a professional and reliable B2B service from one marred by delays and manual errors.

Before evaluating technologies, you need to create detailed specifications. This document precisely defines the features that the system must offer your customers and internal teams, describing the data models, user roles and business logic that will govern the platform.

Use these questions as a starting point for your architecture phase:

User access and authentication: How will customers be authenticated? Will you implement role-based access control (RBAC) for different types of users (e.g., buyers and suppliers)? Do you need to support single sign-on (SSO)?

Pricing and catalogues: Do you need customer-specific product catalogues? How will you manage complex pricing logic, such as tiered pricing based on customer group, contract pricing, or volume discounts?

Order flow: What statuses are required for an order (e.g. Draft, Pending Approval, Approved, Pending Shipment, Shipped)? Will you support purchase orders with term payment conditions, require credit card payments via a payment gateway, or use a request for quotation (RFQ) system?

System integration points: In addition to the WMS, what other systems need to be connected (e.g., ERP, CRM, accounting software)? Identify the critical data fields and API endpoints required for each integration. In addition, determining the priority order of flows is essential.

Once you have defined your requirements, you can select the platform for your shop's user interface. The optimal choice depends on your level of customisation requirements, your internal technical resources and your budget.

Platform type: Description, advantages and disadvantages

Integrated solution providers: Turnkey providers that combine the e-commerce platform, WMS, and physical logistics into a single managed service. Advantage: Guaranteed component compatibility and a single point of contact. Significant reduction in project risks and accelerated time to market. Disadvantage: May lack flexibility for highly specific or atypical functional requirements.​

Unified B2B platforms: Dedicated SaaS solutions, such as CommerceBlitz [1], designed for complex B2B use cases such as quote requests and payment terms. Advantage: Rich, native B2B functionality. Disadvantage: Integration with your specific WMS/ERP depends on API capabilities and may require significant custom development.

Marketplace solution platforms: Platforms such as Unirgy [2] or the open source solution Mercur [3], designed to manage the complexity of multiple suppliers. Advantage: Ideal for companies with a complex supplier or service structure. Disadvantage: Very complex and expensive for a simple private shop.

E-commerce plugins/applications, such as Netwise [4], add B2B functionality to existing platforms such as Shopify. Advantage: Often the fastest and cheapest initial deployment. Disadvantage: High risk of fragile integrations that malfunction during updates; risk of data drift due to API throughput limitations.

For Swiss and European companies looking for an integrated and comprehensive solution, a provider such as Emaloja is the most effective solution. The Emaloja platform combines a robust e-commerce interface with powerful logistics and WMS integration, all managed by specialists for a successful and technically flawless launch.

The WMS is the heart of your supply chain: the reference source for your stock and orders. The success of your project depends on smooth communication between your e-commerce platform and your WMS. Look for a WMS with a well-documented REST API that uses standard data formats such as JSON; this simplifies and secures integration. This API must support a bidirectional flow of product catalogues, stock levels, orders and shipment tracking data.

Choosing the ideal WMS partner depends on your operational scale and existing technological infrastructure:

For enterprise-wide ERP and WMS overhauls: Specialised companies such as LOGWAY Informatik AG manage complex digitalisation projects using flexible platforms such as Odoo.

For large companies using SAP: Consulting firms such as SCM Champs Inc. are experts in integrating advanced SAP Extended Warehouse Management (EWM) solutions.

For SMEs: flexible, cloud-based WMS platforms are often the most suitable solution. Solutions such as StockControl, WMS EasyStorage and Invente Warehouse Management [5] offer powerful features and modern APIs designed for simplified integration.

This is the stage where you connect the components and validate the entire system. Rigorous end-to-end testing is not optional: it is essential to maintain customer confidence and your brand's reputation. A gradual rollout to a small group of trusted customers is highly recommended for final validation in real-world conditions.

Your testing protocol should validate the entire data lifecycle:

Authentication and authorisation: Can a test user log in and view only the catalogue and price levels assigned to them?

Order taking and synchronisation: Does an order placed on the website correctly generate a customer order in the WMS in real time?

Inventory synchronisation: Is the available stock on the website decremented immediately after an order is validated? Is it correctly incremented in the event of a cancellation?

Shipment synchronisation: When the warehouse ships the order, are the order status and tracking number automatically updated in the customer account? Data integrity validation: Do product references, descriptions and prices match perfectly between the e-commerce platform and the WMS?

Data integrity validation: Do product references, descriptions, and prices match perfectly between the e-commerce platform and the WMS?

Fault tolerance and resilience testing: What happens if an API call fails? Does the system have an exponential backoff retry mechanism, or is the data lost?

A successful launch marks the beginning of a cycle of continuous improvement. Your new B2B portal will speed up order processing, highlighting opportunities to optimise your warehouse operations.

Leverage data from your integrated system to make informed decisions. Analytics tools in a WMS such as StockControl [5] help you track key performance indicators (KPIs) such as inventory accuracy, order processing time, and service rate. As your digital order volume grows, your physical layout can become a bottleneck. To stay competitive, partner with experts like Sync Storage Solutions [6] to design your warehouse with optimised racking and conveyor systems, ensuring your physical operations can keep pace with your digital success.

By moving from fragmented manual processes to an integrated digital ecosystem, you are making a transformative investment in your business's operational resilience. Combining a private B2B storefront with real-time warehouse synchronisation eliminates risk, speeds up order fulfilment, and delivers the optimal customer experience demanded by modern customers. This strategic automation allows your team to focus on high-value activities that drive real growth.
