# Merchant Account

A merchant account is the account an acquirer opens for a business to accept card payments: the agreement under which the acquirer processes the business's transactions, settles the funds to its bank account, charges its fees, holds reserves, and is liable to the schemes for its chargebacks. It is not a bank account but a contract with underwriting behind it; a business either has its own, or accepts cards as a sub-merchant under a payment facilitator's.

**Also known as:** Merchant acquiring account, Acquiring account, Merchant ID account

## Key facts

- **Used at:** every business accepting cards — directly, through a payment service provider that resells an acquirer's accounts, or as a sub-merchant of a facilitator
- **Binding:** the merchant agreement — pricing, settlement terms, reserves, chargeback liability, termination rights, PCI obligations — and the scheme rules it incorporates
- **Typical requirements:** KYB and underwriting (business registration, owners, financials for larger merchants, website, category, processing history), a merchant category code, a merchant identification number per account, a settlement bank account
- **Typical terms:** settlement in one to three days (longer for high-risk), pricing as blended, tiered or interchange-plus, monthly minimums and fees, a rolling reserve where risk warrants; termination on notice or immediately for breach
- **Parties:** the merchant, the acquirer (or the PSP fronting it), the sponsor bank behind a non-bank acquirer, the schemes, and for a sub-merchant the facilitator standing in for all of them

## How a merchant account works in practice

A business wants to accept cards. Route one: apply to an acquirer for its own merchant account — forms, documents, underwriting, days to weeks — and receive a merchant ID, a pricing schedule and a contract; transactions settle to its bank account net of fees; it is the merchant of record for the schemes and liable for its disputes. Route two: sign up with a payment facilitator — Stripe, Square, Adyen for platforms — in minutes as a sub-merchant under the facilitator's master account; the facilitator underwrites lightly, settles on its own terms, and is the merchant of record. Route one suits established businesses processing millions; route two suits everyone starting out, at a price.

The account is the acquirer's credit decision. Its terms encode the underwriting: a new online retailer gets a 10% reserve and three-day settlement; a supermarket gets interchange-plus at five basis points and next-day funds. The agreement's termination clause is the risk the merchant rarely reads: an acquirer can end the account on notice, or immediately on a chargeback spike, and a terminated merchant lands on the schemes' MATCH list, which other acquirers check.

For a fintech, "having a merchant account" and "being a payment facilitator" are the two ends of the same spectrum — one account for itself, or one master account with thousands of sub-merchants under it.

## Example

A furniture retailer processing €4m a year moves from a facilitator's sub-merchant account at 1.9% + €0.25 to its own merchant account with an acquirer at interchange-plus 0.25% + €0.08 — a saving of about €40,000 a year after the acquirer's €150 monthly fee. Onboarding takes three weeks: KYB, two years of financials, the website review, a €0 reserve given the two-day delivery gap and clean history. The contract's fine print: 90 days' termination notice either way, immediate termination if chargebacks exceed 1%, PCI SAQ-A obligations since the checkout is hosted. Eighteen months later a supplier failure produces a chargeback spike to 1.4%; the acquirer imposes a 10% reserve rather than terminating, because the retailer called first.

## Common mistakes

- Businesses assuming a merchant account is a bank account and that settled funds cannot be clawed back.
- Choosing the cheapest headline rate on a blended contract without modelling the card mix.
- Not reading the termination and reserve clauses until they are invoked.
- Facilitator sub-merchants outgrowing the facilitator's economics and never applying for their own account.
- A merchant terminated for chargebacks discovering the MATCH list at the next application.
