One shared service that links real bank accounts, feeds balances and transactions to every Synergy app that needs them, and collects exact payment amounts straight from the bank. The bank connection was built once — the whole platform rides on it.
Every product that touches money eventually needs the same three things: link a bank account, read what's in it, and move an exact amount. Most companies rebuild that plumbing for every app. Synergy built it once, as a shared service.
Your bank connects through Stripe, in the bank's own secure login window — your credentials never touch us. Synergy only ever holds a reference to the account, never the keys to it.
Balances and transactions for any linked account, served to any approved Synergy app — amounts and dates cleaned up and tagged so the same transaction never lands in the books twice.
Pull the exact amount owed by bank transfer from a linked, verified account — with the customer's permission captured when they connected. Recurring monthly billing too. A charge can never accidentally run twice.
The proof of a shared service is what's already running on it. Three very different products use SynergyPayments today, and none of them holds bank access of its own:
Adding a fourth product is a matter of granting a key — not a months-long banking project.
The safest secret is the one you never receive. SynergyPayments is deliberately shaped so the sensitive material stays with the bank and with Stripe.
Account linking happens through the bank's own secure login. Synergy sees a reference to the account — never a username or password.
Every request needs its own key — only apps that have been explicitly approved can use the service, not anything that can reach the network.
Every charge carries a one-time fingerprint, so a retry can never take a customer's money twice. Exact amounts, recorded permissions, a full trail of every attempt.
Live means live. The service runs on real money in production — real accounts, real balances, real bank transfers — with the charging machinery proven end-to-end before the switch was flipped.
