A Koi Services company

Payment infrastructure,
built to disappear

Koi Pay gives platforms, ISVs and ISOs a complete payments stack they can put their own name on. We run the gateway, the compliance and the uptime so you can run the brand and the relationship.

01 / About

One gateway behind every channel you sell on

Koi Pay is the white-label payment platform from Koi Services. We unify card-present, online, recurring and embedded payments on a single REST API and dashboard — then hand the whole thing over to you, brandable down to the SSL certificate. Merchants see your name; you see one place to manage acceptance, risk and settlement.

Your brand, not ours

Koi stays off the portal, receipts, emails and terminal screens. The platform is infrastructure — the relationship is yours.

Compliance as a feature

PCI scope minimization, fee-program compliance and fraud controls are built in, not bolted on.

One contract, every channel

In-person, online, recurring and embedded all settle through the same gateway with one reconciliation.

Built for builders

A clean REST API, a Tokenizer, WalletJS and maintained plugins mean you ship in days, not quarters.
