5 Things to Ask Your Credit Card Processor Before Signing a Contract

In 2009, U.S. merchants paid $62.1 milliard to accept credit and debit cards. In 2025, they paid $198.25 billion, according to Nilson Report figures published by the Merchants Payments Coalition. For most businesses, cardstock acceptance is now the largest functioning disbursal following labor.

You would think the rates themselves must have exploded. They haven’t. When the Government Accountability Office studied interchange in 2009, Mastercard’s highest interchange rate was 3.25%. Today it is 3.30%, five basis points in 17 years. Visa’s top charge was 2.95%. It is now 3.15%, but that addition is recent, and most Visa transactions motionless apparent at 2.95% or less. More group paying by cardstock explains much of the growth in that $198 milliard total. It does not explain why so many merchants observe their own productive charge creep up twelvemonth following twelvemonth during the networks’ published rates barely move.

That gap is the processor’s markup and the fees stacked on top of it. I know, since I helped collect them. I spent additional than a decade in the credit cardstock handling division of a business bank, as an administrator at Fifth Third Processing Solutions, afterward Vantiv and Worldpay, now part of Global Payments. During the Great Recession, merchants processed less, so our income fell.

Instead of riding it out, the answer was new fees. The day we announced another one, a monthly accusation of concerning $8.95 per merchant ID, the mood was celebration, not regret. I could no longer do it. I blurted out in a boardroom gathering I got into banking to create my mother proud, and I’m leaving since I could no longer inform my mother what I did for a living. That was January 2009.

Later that year, three another erstwhile executives and I founded a credit cardstock handling auditing resolute to defend merchants from unethical billing practices. Our audits disclose overbilling in concerning 99% of the statements we review, and additional than 90% of the accounts we audit aren’t set up correctly from the start. 

Here’s the crucial math: Interchange, the wholesale disbursal all processor pays, accounts for 80% to 90% of what a merchant should typically pay. A rivalrous markup complete interchange can be as low as 0.02% to 0.05%. However, commonly reported markups range from 0.15% to 0.90%. For example, on $2 myriad in annual cardstock sales, the difference between a 0.50% markup and a 0.05% markup is $9,000 a year, not equal accounting for additional junk fees.

Before you sign, ask these five questions. Get all answer in writing, signed by an authoritative of the company, on paper. Not an email, not a phone call. You desire item that volition clasp up in court.

Question 1: “Is my charge fixed, or can you lift it without my signature?”

Nearly all merchant agreement lets the processor alter its fees, and equal its terms, at any period alongside nothing additional than notice. That notice normally arrives as a row of fine imprint in the communication box on your monthly statement, which nearly nobody reads. Visa and Mastercard publish charge changes twice a year, in April and October, alongside additional than 200 rules and rates changing at once. A processor addition that lands in the identical sequence disappears into that noise. A signed charge is a starting position, not a guarantee.

Question 2: “Will you display me your markup separately from interchange?”

This is the sole most revealing inquiry on the list. Interchange-plus pricing shows interchange on one row and the processor’s markup on another. Tiered and flat-rate pricing blend the two, so you can never inform what the processor is keeping. If a processor won’t unbundle it, it is hiding the markup. Then ask the follow-up: Is interchange passed through at cost, or padded?

Question 3: “What happens if I desire to leave?”

Look for early ending fees, liquidated damages clauses that invoice you for the processor’s projected gain on the remainder of the term, and equipment leases that last following the handling agreement ends. Then discover the auto-renewal clause. Many necessitate you to cancel inner a narrow opening years in the future, and several processors have pushed that notice duration out to 90 days before renewal. By the period most merchants look, the opening has closed and they are locked in for another term.

Question 4: “Which fees on my declaration do you control?”

The cardstock brands set interchange and network assessments. The processor sets much of what sits on top, equal whenever it is named to audio official. “Annual PCI fee,” “regulatory compliance fee” and akin row items audio akin authorities or card-brand charges, and are frequently clean margin. Ask the processor to tag all row on your declaration as either a pass-through or its own. Anything it controls, you can negotiate. That $8.95 fee I watched get invented never appeared on anyone’s declaration as “extra profit.”

Question 5: “Will you put all verbal commitment in writing?”

The traditional throw is a rep quoting a low productive charge that disappears following 90 days, or a commitment to equivalent any recommendation that nobody can discover a twelvemonth later. If the commitment isn’t in the contract, it doesn’t exist.

The agreement is your lone protection

It does not matter how fine your rates are if the agreement lets the processor alter them whenever it wants. Negotiate the agreement as difficult as the pricing: attack or cap the ending fees, shorten or eliminate the auto-renewal and fastener the markup in writing.

Then keep watching. Processors cognize most merchants have no idea what the codes and acronyms on a declaration mean, and the ones who do have too many another fires to expend hours all duration checking for overbilling. That is how accounts drift.

Remember, this is not akin another vendor agreements anywhere you validate the invoice and afterward pay it. With merchant processing, you are giving them unvetted admission to your financial institution document — which I frequently mention to as the “keys to the kingdom.” They obtain what they want, and afterward they dispatch you a declaration that you can’t peruse or validate.

Whether you’re negotiating a agreement or having an attorney vet it to justify you are not signing a bad agreement that could disbursal you a lot of money, you should use a resolute that is an expert in this space. 

Yes, our resolute can assistance alongside that, but many others can as well. However, do your homework, too. Make certain they are not a credit cardstock processor pretending to be a credit cardstock handling auditing firm. Check out their BBB, their LinkedIn profiles, etc., and create certain you dont sign item that is not month-to-month and has a money-back guarantee.
