The question the vendor decks do not answer
Both platforms can show a checkout. Both can take an order against a customer account. The question that actually matters for a trade-led business is what happens on the Tuesday when a buyer with a credit limit places an order that pushes them over the limit, against a job reference that the site office set up that morning, with two approvers in the chain, one of whom is on holiday.
That is a normal Tuesday. The platform either has a clean answer for it or it does not.
Where Shopify Plus B2B actually fits
Shopify Plus B2B is genuinely good now. Company accounts, contract pricing, payment terms and quote workflows are first-class objects, not bolted-on apps. For businesses with a few hundred trade accounts and a credit policy that fits on one page, it is a credible answer and the operating cost is the lowest in the market.
It breaks when the credit policy needs to be enforced in real time against an ERP that holds the actual limit, when partial payments need to be allocated against multiple open invoices, or when the reconciliation back to the finance system needs to handle credit notes, retentions and progress invoicing. Those are not edge cases for distributors and merchants. They are the daily job.
"A trade-account workflow is a finance workflow with a storefront attached. Pick the platform that takes that seriously."
Where Adobe Commerce still earns its licence
Adobe Commerce earns its licence in exactly the places Shopify breaks. The data model is open enough to extend cleanly. The integration patterns for ERP-driven credit are mature. There is a community of engineers who have shipped this kind of logic and can be hired without a three-month run-in.
It also costs more, takes longer to build well and demands a team that can keep an Adobe stack patched and upgraded without losing a quarter to it. That is a real cost and it is the reason teams keep looking for an exit. The exit is real for some businesses. For a trade-led wholesaler with a complex credit book, it usually is not.
The honest decision framework
Three questions usually settle it.
Does the credit limit live in the ERP, and does it need to be enforced at checkout? If yes, you are looking at a real-time integration that Adobe handles more cleanly. Shopify can do it through Functions and apps, but the operating surface is larger than it looks.
Does the approval chain branch based on order value, account type or product category? If the rules are simple, Shopify is fine. If the rules need to be modelled as a workflow with audit, Adobe is the lower-risk choice.
Does finance need to see a clean reconciliation between web orders and the open ledger inside the period close? If yes, the integration with the finance system is the project. Pick the platform that lets you build that integration without rewriting it in eighteen months.
Neither platform is the right answer for every B2B business. The wrong answer is to make this decision on storefront aesthetics and discover the credit logic in sprint nine.
