Merchant agreement: how to read every clause before you sign

A merchant agreement is your contract to take credit and debit cards. It's signed with an acquiring bank, usually alongside the processor or sales company that brought you the deal, and it settles the questions that cost money later: what you pay, when deposits land, how much can be held back, who absorbs a chargeback and what leaving costs. Some providers call it a merchant service agreement or a merchant processing agreement. Same contract, different letterhead.

This guide reads the agreement clause by clause and says what we'd look for in each. For the short checklist, see how to get a merchant account. If a clause still worries you after reading this, take it to a business lawyer before you sign. The network rules and FTC cases below were checked in October 2026.

Who are the parties to a merchant agreement?

Your business and an acquiring bank, and often the company that sold you the account. In Visa's map of who does what, a seller's acceptance contract runs to an acquirer, signed directly or through a payment facilitator (Visa). The acquiring bank settles your card sales and carries the loss when chargebacks outrun what it can collect from you, which explains most of the clauses below.

The company on the sales call is usually a processor or an independent sales organization (ISO). Visa treats ISOs as agents of the acquirer that don't receive settlement funds, so even a contract covered in an ISO's logo should name a bank. Interlink, Visa's debit network, goes further: its rules require the merchant agreement to clearly and obviously specify the acquirer's name and location (Visa). Can't find a bank's name in your paperwork? Ask for it in writing.

With a payment facilitator, you accept the payfac's terms as a sponsored merchant, but the bank still controls that paper. Visa's risk guide for payfacs says the acquirer must approve the merchant agreement a payfac uses to sign sellers, and any later updates (Visa). Visa's acceptance guide adds that the payfac must bring the acquirer into the agreement once a sponsored merchant's annual Visa sales pass a threshold it footnotes at US$1,000,000.

What documents make up a merchant agreement?

Usually four or five, tied together by one signature. Read the signature page closely: it may say you've accepted every document it names, whether or not anyone gave them to you. Ask for the whole set before you sign.

The program guide is the easiest piece to skip. "Incorporated by reference" means the agreement names another document, often a PDF on the provider's website, and makes it part of your contract as if it were printed above your signature. The agreement may also let the provider revise it. Save the version in force on the day you sign, and find the clause that says how changes will reach you.

Banks keep the signed papers, and so should you. The FDIC's examination manual lists a signed merchant application and a signed processing agreement among the minimum documents in a merchant's file (FDIC).

Terms and conditions for a merchant agreement, clause by clause

Ten clauses decide what the account really costs. Here they are in the order we'd read them.

Term and automatic renewal

The pairing to watch is a multi-year term that renews itself unless you send written notice inside a short window before the end date. Miss the window and the contract can roll into a new term, termination fee and all. In its 2022 case against First American Payment Systems, the FTC alleged the company failed to tell merchants its contract was a three-year agreement with a $495 early termination fee, or that it would automatically renew every year (FTC). Ask for month-to-month terms, or at least put the notice window in your calendar the day you sign.

Early termination fees

A flat fee is a set amount for leaving early. A damages formula charges the fees you'd have paid for the rest of the term, often based on your recent monthly average, and that's the one to worry about. With made-up numbers: a dry cleaner in Fort Wayne wants out 14 months into a 36-month agreement, and its processing fees average $280 a month. A $395 flat fee stings. A damages clause asks for $280 × 22 remaining months, or $6,160.

Spoken promises change neither number. The FTC alleged that First American's sales staff told businesses they could cancel without a fee while its standard agreement carried the three-year term and $495 charge, and the order required $4.9 million to go toward refunds (FTC). Ask to see the contract line behind any promise of free cancellation.

Fee changes and notice

Find out whether the provider can raise its own fees mid-term, how much notice you'll get, and whether an increase lets you leave without the termination fee. In the same case, the FTC alleged that First American's savings pitches didn't account for its periodic price increases on existing customers. Small moves add up: 0.10 percentage point more markup on $50,000 a month in card sales is $600 a year. Interchange is different. Mastercard says its rates are typically updated twice a year, and interchange-plus pricing passes those changes through at cost.

In Canada, the Code of Conduct requires 30 to 60 calendar days' notice of new or higher fees, and a right to give notice to exit without penalty within 70 calendar days after the change (FCAC). On a US account, find the notice period in the agreement, or ask for one in writing.

Reserves and holds

A reserve clause lets the bank hold part of your deposits against future chargebacks and refunds. The OCC's handbook for bank examiners says many banks use holdback or reserve accounts with higher-risk merchants, and that a bank may require a reserve or security deposit from a merchant that is financially unstable (OCC). Watch for a right to impose or change a reserve at any time with no release terms, and get the percentage, hold period, cap, review date and release date in writing. Our rolling reserve guide shows the math.

Chargeback liability

Visa's dispute guide says a merchant's liability for disputes is, in most cases, spelled out in the merchant agreement, and that the acquirer absorbs the loss when a merchant's account can't cover a valid dispute (Visa). Look for the clause that lets the bank debit your account to cover them. The OCC adds that chargeback processing and time frames are generally set in the merchant processing agreement. Check the fee per chargeback and whether it's refunded when you win, your deadline to respond, and what happens if your dispute rate climbs. Our chargeback fee guide goes further.

Personal guarantee

A personal guarantee makes you, and not only your company, answerable for what the business owes. It reaches past the LLC or corporation you formed to keep debts separate. In one merchant processing agreement the FTC filed as a court exhibit, the guarantor agrees to cover the merchant's obligations, jointly and severally if there's more than one guarantor (FTC), which means each can be pursued for the whole amount. Look for it near the signature lines on the application. Ask whether it can be removed or capped, and whether it survives after the account closes, since chargebacks can arrive months later.

Equipment leases

A terminal lease is usually its own contract, sometimes with another company, so closing your merchant account doesn't end it. The FTC has warned about card equipment leases costing thousands for hardware worth a few hundred dollars, and noted that whoever signs can be held responsible for the debt (FTC). In New York, the Attorney General sued Northern Leasing Systems over leases for over-priced card processing equipment, and on June 8, 2020, the court ruled for the Attorney General and ordered relief that included rescinding every equipment lease Northern Leasing had obtained (New York Attorney General). Say a lease runs $64 a month for 48 months: that's $3,072, so compare it with the terminal's price.

PCI obligations and fees

The agreement makes card data security your job. The PCI Security Standards Council says compliance and enforcement belong to the card brands and acquiring banks (PCI SSC), and Visa says acquirers must ensure their merchants validate at the appropriate level (Visa). Read the fee lines: a PCI program fee, and the non-compliance fee that starts if you miss your yearly validation. Amex's merchant guide says it and your provider may have the right to impose non-validation fees (American Express). Then read the breach section: who pays for a forensic investigation, and whether network assessments get passed on to you. Our PCI compliance fee guide has more.

Termination for cause and the MATCH list

Expect a clause that lets the bank close your account quickly for cause, such as fraud, excessive chargebacks or selling something you weren't approved for. Visa's standards require a version of it: the merchant agreement must let the acquirer revoke a merchant's Visa acceptance, and merchants terminated for cause are listed on the Visa Merchant Screening Service (Visa).

Mastercard's version reaches further. An acquirer that terminates a merchant for one of the reasons in Mastercard's rules must add it to the MATCH database (Mastercard) within five days of the decision, with details on the principal owners (Mastercard), and the next acquirer's check turns up listings added during the past five years. Read what counts as cause in your agreement, and what notice you'd get. Our Mastercard MATCH list guide explains listings.

Legal terms: disputes, governing law and changes

The back pages decide how a fight with your provider would go:

• Governing law and venue: whose law applies, and where you'd have to file a lawsuit.
• Arbitration and waivers: whether disputes skip court, who pays the arbitrator, and whether you've waived a jury or a class action.
• Limitation of liability: a cap on what the provider would owe you if it makes a mistake.
• Amendments and assignment: whether terms can change by notice, or your account can be transferred to another company.

Each can be reasonable alone. Together they set your bargaining power, which is why an hour of a lawyer's time can pay for itself on a contract you'll live with for years.

Do you sign a Visa merchant agreement?

Not with Visa itself. Your contract is with an acquirer, and Visa's rules reach you through it. Visa's risk standards say acquirers must have a merchant agreement with each of their merchants to accept Visa payments, and they describe it as a direct contract between merchant and acquirer that sets out each side's rights, duties and obligations (Visa). Under the same standards, that contract has to bind you to:

• Follow the Visa Rules, applicable laws and the acquirer's own policies.
• Never knowingly submit an illegal transaction.
• Accept that Visa can limit or end your acquirer's agreement with you.
• Accept that your acquirer can revoke your Visa acceptance.

The standards also list prohibitions, including resubmitting a charge that was already disputed and submitting fraudulent or unauthorized transactions. So "that's a Visa rule" may be true, but it reaches you as a term of your merchant agreement, enforced by your acquirer. Surcharging is a good example: Visa wants 30 days' notice to your acquirer before you add a credit card surcharge, and it caps a US surcharge at the lesser of your merchant discount rate or 3% (Visa). Our surcharging program covers compliance, disclosure and setup.

What's different about a POS merchant agreement?

When a POS company bundles card processing with its software, you can sign three contracts at once: a software subscription, a hardware deal and a merchant agreement. The processing side may be with the POS company acting as a payment facilitator, or with an acquiring bank it works with, and each contract can carry its own term and exit cost. Check three things:

1. Who owns the hardware. Bought outright, it's yours. Leased, rented or "free with processing," it may not be, and the contract says what happens to it when you leave.
2. Whether processing is tied to the software. If the POS works only with its own processing, switching processors means replacing the POS, and a terminal programmed for one processor may not work with another.
3. What leaving costs: the termination fee, remaining hardware payments, any software cancellation charge and the work of exporting your item list and sales history. Ask for that total at month 6 and month 18.

A bundle can still be the right call, since one bill and one support line suit plenty of businesses. Price the exit before the features, that's all. Our guides to what a POS system is and what a POS system costs cover the software side, and cash register vs POS helps if you're not sure you need one. If a standalone terminal suits your counter, our POS terminals come in countertop, wireless and portable models.

How do you review a merchant agreement before signing?

Give it an hour, in this order:

1. Collect every document the signature page names, including today's program guide and any lease.
2. Write the acquiring bank's name at the top of page one.
3. Note the term, the renewal date and the notice window.
4. Work out what leaving would cost at month 12 and month 24.
5. Match the fee schedule to the quote, line by line.
6. Read the reserve, chargeback and termination sections in full.
7. Find any personal guarantee and note what it covers.
8. Get spoken promises, such as "no cancellation fee," written into the agreement.
9. Keep the signed set, program guide included, where you'll find it in three years.

Already signed? Start with the renewal date, then read our guide to hidden fees in credit card processing with your statements beside you; what a merchant account is explains any unfamiliar terms. Card network rules read the same anywhere in the United States. The contract is what varies.
