Unlock Your Revenue Potential with Custom Pricing

One size does not fit all, especially when it comes to the cost of processing payments. We help you maintain full control of your user experience by helping you curate a custom pricing plan with competitive rates tailored to your customers’ needs. No matter how you prefer to control your customers’ processing costs, we have a pricing solution that fits.

We offer 3 different custom pricing models to choose from:

Starting at
2.9% + $0.15 per transaction
  • Craft your own custom flat-rate model with rates starting at 2.9% + $0.15 per transaction and provide your users a simple way to process payments with a clear understanding of what each transaction will cost.

  • Interchange plus is cost-effective route that separates interchange (a fee set by Visa, Mastercard, and Discover that varies by card type) and fixed markup, allowing you to take full control of processing costs for your users.

We know that new features make the world of SaaS applications go ‘round, so as an ISV partner you gain access to more than just basic credit card processing capabilities. Through our all-in-one API, you can offer exciting add-ons — including multiple ways to request, track, and accept payments — all from comfort of your platform.
