Headless Commerce with Shopware: Frontend Freedom for B2B

The Shopware Store API is a complete REST API that makes all Shopware frontend functions accessible programmatically. Product catalogs, category structures, search, cart, checkout, customer accounts and B2B-specific features such as company hierarchies, approval workflows and individual price lists — everything is available via cleanly documented endpoints. The API follows the OpenAPI standard and is fully typed, so frontends can use auto-generated client code.

In B2B commerce, purchasing rarely happens through a single channel. Buyers order via the web shop, field sales staff via an app on a tablet, large accounts via punchout connections from their ERP, and certain products are assembled through a specialized configuration portal. The headless architecture makes exactly this scenario possible: all channels communicate through the same Shopware Store API, and the business logic — customer-specific prices, order approvals, inventory levels and ERP connectivity via our integration platform — lives in a single place in the backend.

In practice this means: when a pricing rule changes in the ERP, the change takes effect immediately across all channels without any frontend updates. New product data, categories or promotional prices are maintained once and automatically available in the web shop, app and punchout portal. PIM integration delivers structured product data into the Shopware backend, from where the API distributes it to all frontends. This central data model is the true value of a well-built headless system: it eliminates data silos not only between shop and ERP but also between your various sales channels.

Headless commerce is not an off-the-shelf product, but without any orientation you are left guessing. That is why we state clear starting prices for the typical build stages here. The exact price depends on the number of channels, the scope of the Store API extensions and your rendering strategy, and is fixed bindingly after a free initial consultation, with no hidden items.

Headless commerce in a B2B context presents different demands than in the consumer space. Complex company hierarchies, multi-level approval workflows and customer-specific catalog views must work just as reliably through the Store API as in the classic storefront approach. In our projects, we have built headless frontends for exactly these scenarios and have proven patterns for mapping complex B2B logic in a decoupled frontend.

We pay particular attention to pricing strategy in the headless context. In B2B, correctly displaying customer-specific prices, tiered rates and framework contract conditions is business-critical. We implement a carefully designed caching strategy that ensures pricing pages are never served with incorrect data: price requests are cached server-side with short TTLs and are never stored in public CDN caches at the customer level. The result is fast price display without the risk of showing one customer another customer's price.

For B2B portals with a strong self-service character — such as the B2B customer portal — the headless approach is particularly well suited. Order histories, invoice archives, delivery status and individual dashboards can be designed far more conveniently and responsively with a modern JavaScript framework than with classical Twig templates. At the same time, the customer portal benefits from the central Shopware backend logic for permissions, company hierarchies and pricing. Our practice articles on Marketplace or Own Shop?
