Card payments
We integrate with your existing checkout. You keep the buyer-facing payment UI, and Outpost collects as Merchant of Record on those rails. This is the B2C card rail - for B2B bank transfer, see Wire transfers.
Integration model
You already have a checkout wired to a PSP. Rather than rebuilding checkout on Outpost, we integrate with your existing checkout so Outpost can act as MoR on those rails - charges settle through Outpost, and you reconcile with the Outpost transaction ID or the PSP reference your systems already know.
When Outpost acts as MoR through a given PSP, the payment methods available are those the PSP supports in that setup. Which combinations are live where is a regional concern - see Solutions.
Supported PSPs
Stripe
Card payments via your existing checkout. For the Stripe Billing-specific MoR guide (Outpost-operated Billing flow), see Integrations. Stripe Billing guide.
