Payment processor

A payment processor is the service that carries a payment request from the merchant, through the card networks and the buyer’s and seller’s banks, to authorise and then settle the money.

How it works

• The payment gateway hands it a payment to authorise.
• The processor routes the request to the card scheme, which asks the issuing bank to approve it.
• On approval, it moves the funds toward the acquirer for settlement — typically a day or more later.

The gateway takes the details; the processor is the machinery that actually moves the money once they are taken.

Why it matters

Processing is where fees, failed authorisations, and settlement delays live. A processor that declines good payments or holds funds for days costs you both revenue and working capital. For a business at scale, the processor’s rates and reliability shape the margin on every sale.

How Fynex does it

Fynex runs the whole money chain rather than bolting one processor onto everything else — routing each payout to the cheapest rail across SEPA, SWIFT, and local schemes, and reconciling every movement back to the books. See payouts.
