What is a merchant account?

A merchant account is a business account, opened through a processor and backed by an acquiring bank, that lets you accept credit and debit cards and receive the money from those sales. Card payments are approved and settled through the merchant account, then deposited into your regular business checking account.

If you take cards today, you already have one, even if you never signed anything with that name on it. This guide explains what the account actually does, who sits behind it, and what to check before you open or switch one.

What a merchant account does

Think of the merchant account as the holding and settlement layer between your customer’s card and your bank. When a customer pays, the sale is authorized in seconds. Later, usually at the end of the day, your approved sales are batched and sent for settlement. The money moves through the card networks to the acquiring bank, and from there into your checking account.

Along the way the merchant account does a few jobs:

• Accepts card payments from Visa, Mastercard, Discover and, in most setups, American Express.
• Settles your sales so the money actually reaches your bank account.
• Handles refunds and disputes, called chargebacks, when a cardholder questions a charge.
• Records fees on a monthly processing statement, one line item at a time.

For the full step-by-step path of a single payment, see how credit card processing works.

Who is involved behind the account

A merchant account isn’t one company. Several parties each play a part, and knowing who does what makes your statement much easier to read.

Party	Plain-English role
You (the merchant)	Sell something and accept the card
Processor	Sets up your account, runs transactions, sends your statement and support
Acquiring bank	Sponsors your account with the card networks and takes on the risk
Card networks	Visa, Mastercard, Discover and American Express set the rules and route the payment
Issuing bank	Your customer’s bank, which approves the charge and bills the cardholder

Most of your day-to-day contact is with the processor. That’s the company that quotes your pricing, answers your calls and decides how much markup to add above the card-network costs. The acquiring bank mostly stays in the background, but it’s the reason you go through an application and review.

Opening a merchant account: what to expect

Because the acquiring bank carries risk on your sales, every merchant account starts with underwriting. It’s a review of your business, not a judgment of you personally. Expect to provide basic information like this:

1. Business legal name, tax ID and ownership details.
2. What you sell and how you sell it: in person, online, over the phone or a mix.
3. Expected monthly card volume and average ticket size.
4. A voided check or bank letter for the account where deposits will go.
5. Recent processing statements, if you already take cards.

Some industries get a closer look than others, usually because of higher dispute rates or delayed delivery. If your business sells memberships, prepayments or goods that ship weeks later, mention it up front. Clear answers at the start make the review go smoother, and they help avoid holds or reserves being added later once the account is already live.

Merchant account vs. the alternatives

Not every business that takes cards has its own dedicated merchant account. Many app-based services use a payment facilitator model, where you’re onboarded under the facilitator’s master account instead. That can be quick to start, but pricing is often a single flat rate, and you have less visibility into what the card networks charge versus what the provider keeps.

A dedicated merchant account usually makes more sense once your volume is steady, when you need features like Level II or Level III data for business cards, or when you want your pricing broken out line by line. We compare the two in detail in merchant account vs. payment facilitator.

It’s also worth knowing that a payment gateway is a separate piece. The gateway carries online or keyed-in payments to your merchant account, the way a terminal does in a store. See payment gateway vs. merchant account if you sell online.

What to check before you sign

The merchant account itself is fairly standard. The terms around it are where businesses get surprised. Before you sign, get clear answers to these:

• Pricing model. Is it Interchange-Plus, tiered or flat rate? Interchange-Plus shows the processor’s markup as its own line, which is the easiest to audit.
• Rate increases. Can the processor’s markup go up later, and is that promise in writing?
• Early termination fee. What does it cost to leave?
• Monthly add-ons. Is there a PCI non-compliance fee, statement fee or monthly minimum?
• Equipment. Are you buying, renting or leasing, and can you keep using what you have?
• Support. When you call, who answers?

We go deeper on this in questions to ask a processor, and in how to compare processing quotes once the offers come in.

What PayZoom does

PayZoom has set up and supported merchant accounts since 2006, for businesses in nearly every U.S. state. We recommend Interchange-Plus pricing, and for Interchange-Plus merchants our margin above interchange never increases. That’s in writing. We don’t charge early termination fees or non-compliance fees, and we help you stay PCI compliant instead.
