How payments fit in
Payment processors often treat firearms sales as high risk. Setting up payments together with DefenderPOS means your application is prepared with that in mind. Approval still depends on underwriting.
- Card and ACH (bank) applications go through one online onboarding process with Full Stack Payments.
- In-person card payments use supported terminals, and online or invoice payments run through the Full Stack Payments gateway, depending on how the software is set up.
- Cash discount, dual pricing, or surcharge programs can be discussed where card brand rules and your state allow them. Rules differ by state, so we review this with you before anything is turned on.
