Opus – your B2B e-commerce development partner

B2B doesn't behave like a regular store. Pricing depends on the customer, orders are bigger, the decision travels through several people, and data has to move between systems. So the same platform won't suit everyone.

We don't push one solution on everybody. We start by looking at what your business actually needs, then build on Magento, MedusaJS, from scratch, or on the platform you already run.

B2B buyers are already asking chatbots

Procurement teams look for suppliers and products in ChatGPT, Gemini and the rest more and more often. If your store isn't readable to them, you stay out of the answers – even when you rank first on Google.

Being readable comes down to something fairly simple: the data has to be structured, current, and reachable through an open interface.

MCP integrations for B2B and B2C stores

MCP (Model Context Protocol) is a standard that lets an AI agent connect securely to your store's data and functions: the catalogue, stock levels, prices, even placing an order.

We build MCP interfaces for B2B and B2C stores alike. In B2B that means a customer's purchasing system or agent can check a price and availability directly, or place the order there and then. In B2C, a shopper finds your products in the chatbot and compares them without leaving it.

Platforms we use to build B2B stores

Magento

A mature, widely used platform. It holds up when pricing and customer-group rules get complicated.

Magento development

MedusaJS

An API-first headless platform. Business logic changes quickly and new channels, AI agents included, are easy to connect.

MedusaJS development

Custom development or your own platform

When an off-the-shelf solution starts to hold you back, or a platform is already in place, we build straight on top of it or from scratch.

Google Merchant Center
We set up your product feed in Google Merchant Center and keep it in order, so your products reach Google Shopping and other Google channels with the right data.
Structured data
We add schema.org markup to product pages so search engines and chatbots read your products and prices correctly.
MCP / API interface
We build the interface that lets AI agents and partner systems query your store and place orders.

E-commerce integrations

Content management (CMS)

We connect the store to a content management system, so marketing can manage campaigns, banners and pages without a developer.

Akeneo

Akeneo PIM handles product information only. We set it up by product family and connect it to the ERP and the online store.

AI search

AI-based product search understands the shopper's question, not just keywords, and finds the right product without its exact name.

Warehouse management system

We connect the online store to the warehouse management system, so stock levels, picking and delivery move between the systems automatically.

Maintenance and support after launch

A store and its AI interfaces need steady care: the platform wants updates, the feed wants watching, the interfaces want checking.

We stay on as your partner after launch, so the store and its data keep working – in search and in chatbots.

Auditing an existing store

If the store is already running, we start with an audit. We review speed, the customer journey, accessibility, SEO, security and integrations, and give you a written overview of what is in order, what needs fixing and what is critical.

The audit gives you a prioritised list of work, so you know where to put the money first.

Accessibility

Frequently asked questions

  • How is a B2B online store different?

    In B2B, prices depend on the customer, orders are larger, purchase decisions involve several people and data has to flow between systems. That is why one platform does not suit everyone.

  • Which platform should a B2B store be built on?

    Magento suits you if you need a mature platform with complex price and customer-group rules. MedusaJS suits an API-first headless solution that can quickly follow your business logic. A custom build is the right choice when your processes are so specific that a ready-made platform would hold you back.

  • How does a B2B store become visible in AI chatbots?

    The data has to be structured, current and available through an open interface. We add schema.org markup to product pages, keep product feeds in order and, where needed, build an interface AI agents can query.

  • What is an MCP interface and what does it give a B2B store?

    MCP (Model Context Protocol) is a standard that lets an AI agent connect securely to your store’s data: the catalogue, stock, prices and orders. In B2B, a customer’s purchasing system or agent can ask for prices and availability directly or place an order. There is no need to change platform; the interface is built onto your existing system.

  • Can you help with an existing B2B store?

    Yes. We start with an audit of speed, the customer journey, accessibility, SEO, security and integrations. An AI readiness audit shows how AI assistants see your store today and what to fix first.
