Money leaves when you decide
There is no fixed settlement window to wait for. Check the amount, check your limit, then move it — the availability window is open rather than batched.
When one provider stops, the payment does not
A gateway that runs one channel fails whenever that channel does. Ours scores the channels it has and moves away from the ones that are struggling.
Finance console
A console your finance team can work from
Balance per currency, per organization, across a multi-level organization tree
Role-based access down to the action — menu and create/read/update/delete set separately
Audit trail of logins, permission changes and significant actions, kept separate from the money ledger
For developers
One signed call. One callback. One entry.
The whole integration is a REST endpoint you sign, a callback you verify, and a status you can always ask for again.
