How to set up surcharging, step by step.

To set up surcharging, find your real cost of accepting credit cards, confirm current card-brand and state rules, give any required advance notice, then configure your terminal or gateway to add the surcharge to credit cards only. After that, post disclosure at entry and checkout, make sure the receipt shows the surcharge on its own line and train your staff before the first customer sees it.

Below is how to set up surcharging in seven steps, in the order that avoids rework. If you are still deciding whether surcharging fits your business, start with what is surcharging or compare it with the alternatives in surcharge vs. cash discount vs. dual pricing.

Before you touch the terminal

Step 1: Find your cost of acceptance

Your surcharge can’t exceed 3%, and it can’t exceed what it actually costs you to accept credit cards. Pull your most recent processing statements and work out what you pay on credit card sales: interchange, card-network fees and your processor’s fees. If that total comes to less than 3% of your credit volume, your surcharge must be lower too.

If you can’t make sense of your statement, you are not alone. A line-by-line review clears it up quickly, and it may reveal that you are overpaying for processing, which is worth fixing either way.

Step 2: Check current rules

Card-brand rules set the baseline: credit only, capped, disclosed and shown on the receipt. Some states restrict surcharging or add their own requirements, and those rules change. Check the current rules for every state where you sell, including online sales to customers in other states. Our surcharging rules guide summarizes the card-brand side. This guide is not legal advice, so ask your own advisor if anything is unclear.

Step 3: Give advance notice

The card brands may require advance notice before you begin surcharging. Ask your processor what is needed and how it is submitted, and keep a record. Plan your launch date with that lead time in mind.

Step 4: Configure credit-only surcharging

Your terminal, POS, gateway or online cart needs to do three things on every transaction:

• Detect the card type by BIN. Debit and prepaid cards must never be surcharged, even when run as credit. A “debit or credit” prompt is not enough. See can you surcharge debit cards for why.
• Apply the right percentage. Use the rate you settled on in step 1, at or under the cap.
• Print the surcharge separately. The receipt should list the sale, the surcharge and the total.

Set up every place you take cards, not just the main counter. That includes mobile terminals, virtual terminals, invoices with pay links, online checkout and any stored-card or recurring billing.

Step 5: Post your disclosures

Customers need notice before they pay, in two places: where they enter your business or website, and at the point of sale. The notice should say that a surcharge applies to credit cards, give the percentage and make clear it doesn’t apply to debit. Our guide to surcharge disclosure and receipts covers wording and placement.

Step 6: Test before launch

Run test transactions before customers do. Check each scenario:

Test	Expected result
Credit card, chip or tap	Surcharge added at your set rate
Debit card with PIN	No surcharge
Debit card run as credit	No surcharge
Prepaid card	No surcharge
Keyed or online credit card	Surcharge added, shown on confirmation
Full refund on a surcharged sale	Surcharge refunded too

Launch day and after

Step 7: Train your staff and review

Your team will get questions. Give them a short, honest answer to use: the surcharge covers part of what credit card processing costs the business, it applies to credit cards only, and debit, cash and check pay the posted price. Make sure they know how to process a refund that includes the surcharge.

After launch, keep the program healthy:

1. Review your cost of acceptance when your statements change, and adjust the rate if needed.
2. Re-check state and card-brand rules from time to time.
3. Update signs, website notices and terminal settings together whenever anything changes.
4. Spot-check receipts so you catch a misconfigured device early.

Common setup mistakes

The programs that run into trouble usually skipped a step. The most frequent: setting the surcharge at 3% without checking actual cost, relying on cashiers to decide card type, forgetting the online checkout, posting a sign only at the register and launching before the advance notice is handled. Each one is easy to avoid when you work through the steps in order.

Two more are worth calling out. First, merchants with recurring billing sometimes turn on a surcharge for stored cards without telling those customers ahead of time, which invites disputes. Second, businesses with several locations sometimes configure one store correctly and leave the others on old settings. A short audit of every device and checkout before launch prevents both.

What PayZoom does

PayZoom handles most of this checklist with you. We read your statement to find your cost of acceptance, help you review current rules, and set up credit card surcharging capped at 3% with BIN-based debit and prepaid detection on your terminals, POS, gateway or cart. We configure receipts to show the surcharge on its own line and help you plan your signs.

Because we are platform-agnostic, we work with the equipment you have where we can, and supply terminals when you need them. Start with a free statement analysis, or call 866.242.4325 to talk with a real person.
