Here is a plain example. An online retailer opens a merchant account with an acquiring bank. A customer pays $100 by card. That $100 settles into the merchant account first, fees are deducted, and the remainder transfers to the retailer's business checking account. The merchant account is the holding point between the customer's card and the business's bank.
Every business that accepts card payments has one, whether it was opened directly with an acquiring bank or provided behind the scenes by a payment service. Below are concrete examples: how one transaction moves through an account, what the different account types look like in practice, and what changes when the business is high-risk.
What a merchant account is, in one paragraph
A merchant account is an account a business holds with an acquiring bank so it can accept credit and debit card payments. It is not the same as a business checking account. Card payments settle into the merchant account, and the acquiring bank then transfers the funds to the business's own bank account. If you take cards in any form, a merchant account sits somewhere in that chain.
A merchant account example: one $100 card sale
Follow a single $100 payment through the account:
- Authorization. The customer's card is charged. The card-issuing bank approves or declines the transaction in seconds.
- Settlement. The approved $100 settles into the merchant account held with the acquiring bank.
- Fees come out. Interchange — the fee set by the card networks and paid to the issuing bank — is deducted, along with the processor's markup. Interchange varies by card type, so the exact figure differs from one transaction to the next. With us, pricing starts at interchange plus 0.80%, with every fee disclosed in the merchant service agreement before you sign.
- Deposit. The remainder transfers from the merchant account to the business's checking account.
The merchant account itself is the middle of that flow: the place where funds land, and where fees are reconciled, before the money is yours.
Types of merchant accounts, with an example of each
The structure above stays the same across industries. What changes is how the card is presented and how the account is underwritten.
A retail merchant account. A storefront runs cards through a terminal. Card-present transactions carry lower fraud risk, which generally means lower rates.
An e-commerce merchant account. An online seller accepts cards through a checkout page. Card-not-present transactions carry more fraud and chargeback exposure, and the account is underwritten with that in mind.
A mobile merchant account. A contractor or market vendor takes payments on a phone or tablet in the field. Same account structure, different acceptance hardware.
An example of a high-risk merchant account
Now take a business in a category banks classify as high-risk. The account works the same way — authorization, settlement, fees, deposit — but three things change in the example.
First, underwriting goes deeper. The acquiring bank reviews processing history, chargeback rates and financials before approving the account, not after.
Second, the bank may hold a reserve: a portion of settled funds retained against future chargebacks. We have written separately about how a rolling reserve works, with a worked example, so we will not repeat the math here. The short version is that reserve terms belong in the agreement, in writing, before you sign.
Third, placement matters. Not every acquiring bank accepts every industry, so high-risk merchant accounts are opened with banks that underwrite the specific business type rather than declining it on category alone. That placement is the whole job, and it is the only work we do.
What an example account shows you before you sign
A well-documented merchant account is legible before it is live. The example to hold yours against: the rate structure is stated, any reserve terms are stated, and both appear in the merchant service agreement rather than arriving after approval. If you cannot read the terms in plain language, ask for a plainer version.
