Dual Pricing

Transparency at Checkout.

How does it work?

Step 1:
A business chooses to display two prices rather than one — a cash price and a card price.
Step 2:
Full Stack Payments implements a compliant point-of-sale solution that automatically shows both prices to customers, ensuring clarity before payment.
Step 3:
When a customer pays by card, the system automatically applies the card price, which includes the cost of acceptance.
The difference between the two prices is used to cover the processing expense — no additional fees are ever added at checkout.

Questions and Answers

Yes. Visa permits dual pricing when customers are clearly presented with both a cash price and a card price, as long as no fee is added at the point of sale. Stackably’s technology ensures all displays, receipts, and disclosures follow these guidelines.

No. Dual pricing is not a surcharge. With surcharging, one price is shown and an extra percentage is added at checkout when paying by credit card.


Dual pricing offers two prices upfront, letting customers choose how they want to pay. The card price already includes the cost of acceptance — no fee is added at checkout.

Yes, the card price applies to both debit and credit transactions.


While debit transactions often cost merchants slightly less, businesses still pay network and processing fees on both.


Full Stack Payments blends those costs to maintain two simple, transparent prices instead of separate debit, credit, and cash prices.

No. The higher card price collected through the system is used solely to cover the cost of card acceptance and processing.


The technology automatically manages this allocation — keeping the program fair, transparent, and compliant for both merchants and consumers.

Our Commitment to Transparency

Full Stack Payments built this program to meet or exceed VisaMastercard, and state disclosure standards for transparent pricing.

Customers always see both prices before paying, and receipts reflect only the final total — never an added fee or separate line item.

This program aligns with the transparency and consumer choice principles reflected in federal law, including Section 1075 of the Dodd–Frank Act (15 U.S.C. § 1693o–2(a)(2)), which prohibits payment card networks from restricting merchants who offer discounts or in-kind incentives for specific forms of payment such as cash.
