Built for Your Platform. Designed for Your Merchants.

No two payment stacks are alike, and adding surcharging shouldn't mean changing yours. InterPayments engineers a compliant solution around the systems you already run on, so nothing gets rebuilt or replaced.

One API, Two Ways to Serve Your Merchants

Use the InterPayments API to build compliant surcharging directly into an individual merchant's payment environment, custom-fit to how they operate.

Support complex, highly customized payment setups

Design around the way each merchant already operates

Powering Your Surcharging Program End- to- End

Everything your program needs to launch and stay compliant, in one package.

Every Step, Fully Supported

Whether you're onboarding a single merchant or deploying across your entire partner network, InterPayments works alongside your team to configure, deploy, and optimize surcharging, so every implementation is set up for fee recovery from the very first transaction.

Map the Integration

Work directly with solutions architects to scope the build, define your surcharging requirements, and design an integration that fits your exact payment environment.

Certify the Build

Partner with InterPayments’ compliance team to certify your integration, confirm coverage across every applicable regulation, and secure indemnification against compliance risk.

Launch the Program

Team up with implementation experts to launch compliant surcharging across your merchants' environments, with recommended messaging to communicate the change to customers, so the rollout is smooth and adoption lasts.

Best-in-Class Surcharging Precision

Every program is designed, certified, and supported by an implementation team, giving your merchants a full toolkit to recover fees and protect their margins.

Selective Surcharging

Target fee recovery by customer segment, product line, geography, or payment terms, without applying a blanket surcharge across every transaction.

Surcharge Customization

Waive, discount, or apply time-based surcharges to match how each merchant operates. Every rule is configurable, so the program fits their unique business model.

CEDP and Savings Data Support

Capture and submit the detailed transaction data that qualifies eligible commercial cards for lower interchange rates, with automated ERP connectors handling the heavy lifting.

Cost-of-Acceptance Tracking

Know each merchant's true cost of accepting every card, so surcharges stay capped to that cost, fair to customers and always compliant.

Surcharging Education

Surcharging Is Complicated. InterPayments Makes It Simple.

Learn the ins and outs of surcharging from the team that does this all day. Get everything from the basics to the latest regulatory shifts, so you never have to untangle the rules alone.
