# Acquirer

An acquirer is the bank or licensed institution that lets a merchant accept card payments: it holds the merchant account, routes each transaction to the card network for the issuer's approval, settles the money to the merchant and is liable to the network for the merchant's chargebacks. In M&A the same word means the buyer of a company; in payments it means the merchant's bank — the most consolidated corner of fintech M&A.

**Also known as:** Merchant acquirer, Acquiring bank, Acquiring institution

## Key facts

- **Used at:** every card payment — the acquirer sits between the merchant and the network, the issuer between the network and the cardholder
- **Binding:** an acquirer is a principal member of Visa and Mastercard, bound by their rules and liable for its merchants' obligations under them; a merchant agreement governs each merchant
- **Typical economics:** the merchant service charge, from which the acquirer pays interchange to the issuer and scheme fees to the network, keeping a margin of a few basis points to a few tenths of a per cent depending on the merchant's size and risk
- **Typical M&A:** the 2019 wave — Fiserv–First Data, FIS–Worldpay, Global Payments–TSYS — and its unwinding, with FIS selling 55% of Worldpay to GTCR in 2023 at an $18.5bn valuation and Global Payments buying it back in 2025; bank acquiring units sold to specialists across Europe
- **Parties:** the acquirer, its merchants, the card networks, the issuers on the other side, and the processors and facilitators that operate under its licence

## How an acquirer works in practice

A cardholder pays €100 at a merchant. The merchant's terminal or gateway sends the transaction to the acquirer, which forwards it through the network to the issuer, which approves or declines. On approval the acquirer credits the merchant — typically the next day or two — and collects the funds from the issuer through the network's settlement, less interchange, which stays with the issuer. The acquirer charges the merchant its merchant service charge, covering the interchange, the scheme fees and its own margin. If the cardholder disputes the transaction, the chargeback comes back through the network to the acquirer, which recovers it from the merchant — if the merchant is still there.

The business is therefore three things: distribution, risk and scale. Distribution is winning merchants — through sales teams, banks, software platforms and payment facilitators; risk is underwriting merchants so that chargebacks and fraud can be recovered, which is why acquirers hold reserves and price by industry; scale is what makes the margin work, because the acquirer's costs are largely fixed and the margin per transaction is measured in basis points. Consolidation follows from the third: the largest acquirers process trillions and the spread between their unit cost and a mid-sized bank's is the acquisition case.

The word's two meanings collide in this glossary: in the deal record an "acquirer" buys a company; on this page it buys a merchant's card transactions. The context makes it clear, and on a payments deal both are in the room.

## Example

A regional bank's acquiring unit processes €12bn a year for 30,000 merchants at a net margin of 0.18% — €21.6m of revenue — on a platform whose fixed cost is €14m. A specialist acquirer processing €400bn offers €150m for the unit: it will migrate the merchants to its own platform, whose marginal cost for the volume is €3m, and keep the bank as a referral partner for a share of the margin. The unit's €7.6m of profit becomes €18m in the buyer's hands, and the price — 20× the unit's standalone profit, 8× its profit in the buyer's — is a synergy case the bank could never have realised alone. The regulator approves the transfer of the merchant contracts; the card schemes approve the buyer as the new principal; the migration takes fourteen months and loses 9% of the merchants.

## Common mistakes

- Confusing the acquirer's margin with the merchant service charge, most of which is interchange passed through.
- Underwriting merchants on volume without the delivery gap that sets the chargeback exposure.
- A bank valuing its acquiring unit on its own profit rather than on what a specialist would earn from the volume.
- Buyers of an acquiring business who assume the merchant contracts move without consent, or the scheme membership without approval.
- Writing "acquirer" in a deal document without saying which kind.
