What sub-second payment processing actually requires under the hood — and why most gateways fall short of it.
"Instant payments" gets used loosely. In practice, most gateways still take seconds — sometimes several — between a payment request and funds actually clearing, because each step (validation, compliance screening, rail selection, settlement) runs as a separate, sequential call to a separate system.
BipraPay's average end-to-end time is 748 milliseconds, broken down roughly as: 12ms to receive and validate the API call, 48ms for real-time AML screening, 8ms to select the fastest compliant rail, and the remainder — about 680ms — for the bank to confirm settlement. Every stage happens inside the same platform, so there's no queueing between systems waiting for a response.
That 748ms average compares to a industry average closer to 2,200ms — roughly three times slower — mostly lost to hand-offs between a payment processor, a separate compliance vendor, and a separate reconciliation system.
The other half of the story is what happens after the money moves: every transaction auto-generates an immutable, SARB-compliant audit record at the same time it settles, rather than requiring a second reconciliation pass days later. Speed and auditability turn out to be the same architectural decision, not a trade-off.
