Payments can be a cost centre or a revenue line

If your customers take payments through you, you are already in the payments business. The question is whether the economics work in your favour.

What this actually fixes

Payment revenue is not modelled: Per-account cost and revenue modelling so you can price your take rate deliberately.
Onboarding friction loses customers: Embedded KYB tuned per country and business type, with drop-off measured per step.
Support burden from payment issues: Decline reasons and dispute status surfaced to your support team in plain language.
Building this in-house is a roadmap: Embedded components you configure rather than a ledger you maintain.
