Common Questions

Payment Integrations FAQ

What business software does Flat Rate Processing integrate payments with?

FRP connects to the tools you already run, including gateways like Authorize.Net and USAePay, MX Merchant, smart terminals from Dejavoo and Valor PayTech, WordPress and WooCommerce, and QuickBooks. We also have a dedicated integration with the Wayne Reaves DMS for auto dealers, plus support for hundreds of other platforms.

Can I add card and ACH acceptance inside my existing system without changing platforms?

Yes. FRP is built to work with your current stack, so there is no rip-and-replace. For example, you can accept cards and ACH directly inside QuickBooks with automatic reconciliation, keeping the accounting software you already use.

Do payments reconcile automatically with my accounting software?

With the QuickBooks integration, card and ACH payments post and reconcile automatically, so there is no double entry. That keeps your books accurate without manual matching after each transaction.

Do you support industry-specific software like auto dealer DMS?

Yes. FRP is an exclusive integration partner with Wayne Reaves, with payments built directly into the DMS for auto dealers. Beyond that, we support 90%+ of eligible vertical platforms, so tell us what you run and we will confirm the path.

Do I need a developer or technical help to set up an integration?

Most integrations connect through existing gateways, terminals, or plugins, so you usually do not need a developer. Our team handles the setup and configuration with you, and for custom needs USAePay and Authorize.Net offer developer APIs.

Does integrating payments change how or when I get funded?

No. Integrating simply connects your software to your merchant account; it does not change your standard funding schedule or deposit process. Your transactions are still funded to your bank the same way.
