Dual Pricing & Cash Discount
Lower your credit card processing fees

Dual pricing lets you display two clear prices at checkout: one for cash and one for card. Customers choose how they want to pay, and the small cost of card acceptance is handled transparently, so your business keeps more of every sale.

A compliant cash discount program works the same way, rewarding cash-paying customers while keeping your card pricing fair and easy to understand. ProTech Payments sets everything up for you, from signage to receipts, so you stay compliant with card brand rules and state regulations.
