A merchant account is the arrangement that lets a business accept card payments and receive the money. This guide explains how it differs from flat-rate payment services, what you need to apply and how to compare providers. It is general information, not financial or legal advice.
What a merchant account is
When a customer pays by card, the funds move from the customer’s bank, through the card network, to a bank that settles with you. A merchant account is the agreement that connects you to that process. Some providers give each business its own account. Others process many businesses under one provider account, and Toast’s pricing page describes this kind of model when it says it “is a payment facilitator that partners with processors.”
Merchant account vs flat-rate payment service
With a flat-rate service you sign up and start taking payments under a published percentage plus fixed fee. With an interchange-based merchant account you typically pay the card network’s interchange plus a markup or subscription, as Stax describes: a subscription “starting at $99 a month” with “0% markup on direct-cost interchange” plus a flat fee per transaction. Neither is always cheaper; it depends on your volume, average sale and card mix. Read interchange-plus vs flat rate.
What you will need
Providers ask for details about your business and owners. Many also expect an EIN and a business bank account. You can get an EIN directly from the IRS for free; the IRS says you never have to pay a fee for one. Our LLC guide and bank comparison cover those steps.
How to compare
Look at the total cost at your volume, plan or subscription fees, contract and cancellation terms, dispute fees, funding speed and support. Providers that publish their pricing are easier to compare; for those that do not, request a written quote. Use our processing fee calculator for the published flat-rate options.

Frequently asked questions
What is a merchant account?
It is an arrangement with a provider and bank that lets a business accept card payments and receive the funds. Some providers give you your own account; others process your payments under their account.
Do I need a merchant account?
Not always. Flat-rate providers let you start without negotiating one, while higher-volume businesses sometimes choose their own account with interchange-based pricing. Compare the terms and total cost.
What do I need to apply?
Requirements vary by provider. Commonly a business name, an EIN or similar tax ID, a business bank account and details about what you sell. Our LLC guide covers the setup steps.
How long does approval take?
It varies by provider and your business type. Check the provider's application page.
Is interchange-plus only for merchant accounts?
Not strictly, but it is the pricing model usually associated with them. Stax, for example, publishes a subscription with 0% markup on interchange.
