It is easy to scope a B2B Commerce Cloud project as “build the storefront”. The storefront is the visible part, so it absorbs the attention and the budget. But B2B buying is not a single transaction on a single screen — it is a relationship that spans accounts, contracts, approvals, support, and reordering. Treat Commerce Cloud as just a storefront and you ship something that demos well and frustrates real buyers.
B2B complexity lives outside the cart
A B2B buyer rarely arrives, adds to cart, and checks out. They operate within an account hierarchy, against negotiated pricing, often needing approval before an order is placed. They reorder from history. They raise a case when something is wrong. None of that is storefront UI — it is account data, entitlement logic, and service integration. If the data model and integrations were not designed for it, no amount of frontend polish will fix the experience.
Service is part of commerce
When a B2B order has a problem, the buyer expects support that already knows the order, the account, and the history. If Commerce Cloud and Service Cloud are disconnected, the buyer re-explains everything and the agent works blind. Designing the commerce-to-service path — Web-to-Case, order context, identity resolution — is what makes post-purchase support feel like part of the same system rather than a separate company.
Portals carry the account relationship
Much of the B2B relationship happens in the authenticated account experience: viewing orders, managing users, accessing documents and pricing, raising requests. That is Experience Cloud territory, and it depends on the role model and sharing rules being right. A storefront bolted on without a coherent portal and permission strategy leaves the account relationship homeless.
Data is the connective tissue
Orders, accounts, cases, and marketing interactions only become an experience when they share a customer profile. This is where Data Cloud and identity resolution pay off: the same buyer is recognised across storefront, portal, service, and marketing, so each interaction builds on the last. Without it, you have several systems that happen to share a logo.
Design connected from day one
The fix is not to boil the ocean. It is to scope the storefront as one part of a connected system, and to design the data model, identity strategy, and service and portal touchpoints alongside it — even if some are delivered in later phases. That sequencing decision, made early, is the difference between a B2B commerce platform that grows and one that has to be rebuilt.
Commerce is the wedge into an intelligent Salesforce estate. It only works as a wedge if it is connected to everything behind it.
