What slows teams down

Problems we hear from Software ISV programs

  • Gateways that go around you

    Vendor-led upsells, side ISO programs, or a competing platform launched into your vertical the next quarter. Every "partner" gateway has a path that quietly cuts your software out of the loop.

  • Bolted-on integrations

    One-off gateway adapters slow every release. You need predictable patterns for tokens, webhooks, idempotency, refunds, and disputes — not a different shape on every endpoint.

  • Card-present as an afterthought

    When your customers eventually need terminals, your gateway treats hardware as a separate product, with a separate vault and a separate report. The "embed" story breaks the day card-present matters.

What changes with Fluid Pay

Outcomes we optimize for

  • Built for embedding, not bolting on

    REST + webhooks. Idempotency keys. Token-based vault. Component library for desktop and mobile. Sandbox you can hit in 60 seconds.

  • We don't go around you

    Partner-only by design — we don't sign up your end users behind your back, and we don't license a competing platform to your competitor next month.

  • One contract covers card-present and online

    When your customers eventually need terminals, we have those — same vault, same reporting, same API. You don't change vendors when card-present matters; you just turn it on.
