Embed payments in your software

For POS makers, booking and ordering platforms, and ISOs. Board merchants under your own reseller hierarchy, white-label the portal and hosted checkout, and earn an ongoing residual split under our ISO partner program. The same gateway API powers Universal Processing's own uLite POS and uLite Online products in production.

ISO model & residual split

Partner with a registered ISO serving 35,000+ U.S. businesses. Board your merchant book under your own reseller hierarchy with a transparent residual split and flexible merchant fee schedules.

White-label portal & checkout

Put your own brand, custom domain, logo, sender email and SDK namespace on the merchant portal, hosted payment pages and embedded checkout.

Multi-location tokens

With token sharing on, a card saved at one location can be charged by another under the same reseller—built for restaurant groups, clinic groups and multi-unit chains.

Processor routing & failover

Assign multiple processor profiles per merchant. Routing rules pick the right acquirer per transaction and fail over automatically if the primary doesn't process.

Engagement tools Beta

Campaigns, promotion codes and SMS messaging APIs for building merchant-facing marketing and payment-link workflows.

Accounting connect

OAuth connect flow for QuickBooks Online and Xero, with a synthetic loopback provider in the sandbox for end-to-end sync testing.
