TL;DR: B2B buyers pay by wire transfer and purchase order. Hosted ecommerce checkouts mostly take cards. Merchants either lose the order at the payment step or drag it into spreadsheets and email. PainHunt's Payment Processing data points at a narrow, unglamorous wedge: make offline payment methods first-class inside B2B checkout.
The evidence
Payment Processing is one of the highest-intensity clusters in the current data: 481 posts scoring 10+/15, average intensity 7.8/10, average score 11.6. The high-signal posts in this domain surface mainly on Bluesky and Discourse, with a tail on Medium, the App Store, and Dev.to.
The B2B thread inside it is unusually specific. Merchants describe B2B customers being unable to use bank transfer, wire transfer, or direct debit in checkout because only cards are offered. They report that the large majority of their wholesale resellers prefer wire transfer, and that orders are simply lost when a buyer reaches the payment page and cannot pay the way they normally pay. The stated workaround is to process the payment outside the platform, which costs them the integration and the tracking.
The requested feature is stated plainly rather than aspirationally: enable manual payment methods — bank transfer, wire, ACH, direct debit — for B2B customers inside checkout.
Why now
B2C checkout has been optimized to death, and the tooling reflects it: one-click, card-first, conversion-obsessed. B2B ran on a different rail the whole time — POs, invoices, net 30, a finance team that will not put a company card into a web form.
The two worlds have now collided inside the same storefront. Hosted platforms added B2B modes so merchants could serve wholesale and retail from one catalog, but the payment layer largely inherited the B2C assumption. Meanwhile the buyer side did not move: procurement still wants an invoice, and a wire is still how a five-figure reorder gets paid.
That leaves a growing population of merchants running B2B volume through a checkout that structurally cannot take their buyers' money.
The wedge
Sell the missing payment method, not a B2B platform.
- A checkout app that adds bank transfer, ACH, and wire as selectable methods for tagged B2B customers, with the order held in a clean pending-payment state rather than dropped.
- Automatic reconciliation: match the incoming transfer to the pending order and release it, so the merchant is not eyeballing a bank statement.
- Net terms as a first-class state — invoice issued, due date tracked, order fulfilled on approval — without pretending to be a lender.
Land on "your wholesale buyers can finally pay by wire without leaving checkout," then expand into approval workflows, credit limits, and buyer-specific terms.
Risks and honest caveats
- Platform dependency: if the underlying commerce platform ships native offline payment methods for B2B, the standalone case narrows sharply. The durable position is reconciliation and terms management, not the checkbox itself.
- Reconciliation is genuinely hard: matching bank transfers to orders across currencies, partial payments, and mangled references is where the work is, and where a shallow product will fail.
- Not a credit product: offering net terms without underwriting shifts risk onto the merchant. Be explicit that you are tracking terms, not guaranteeing payment, or you back into being a lender.
- Fraud surface: a pending-payment order state that releases inventory on an unverified promise is an abuse vector. It needs deliberate design.
