Synapto

Your software already moves your customers' money. Getting paid for it usually means a rebuild. Synapto is a UK payments provider built API-first for platforms, marketplaces and software companies that collect payments and pay people out. One integration covers both directions. Collect card and Direct Debit payments, then fire payouts from your own events: a job marked complete, an order dispatched, a shift signed off. Every payment in is matched to every payout out automatically, so reconciliation isn't a spreadsheet job. Payouts are configured, not built. No development project sitting on your roadmap waiting for a payments release. Pay-ins live in two days. Same-day and next-day payouts. GBP settlement on UK rails. Merchants switching from a standard PSP cut processing costs by 30% on average, and you get a named account manager who answers the phone, not a ticket queue.
