Reserve Account
A reserve account holds funds a bank, acquirer or partner keeps back against future chargebacks, refunds or unsettled exposure, released on an agreed schedule. The money is economically yours, but it is out of your hands while it is held.
Also called: rolling reserve · security deposit
A reserve account holds money a counterparty keeps back rather than pays over, against losses it may have to cover later. An acquirer holds one against future chargebacks and refunds; a payout partner or sponsor bank holds one against unsettled exposure or fraud. It is a credit instrument in the shape of an account, and often no more than a controlled balance on the counterparty’s own books.
Two shapes are common. A rolling reserve withholds a share of each settlement and releases it a fixed period later, so the balance builds to a steady level and stays there while volumes hold up. A capped or fixed reserve is funded once to an agreed figure and topped up only when it is drawn on.
What to read in the contract
- The share or amount withheld, and what it is calculated on.
- The release period, and whether releases happen automatically.
- What lets the partner increase it — usually a chargeback ratio or a loss event.
- How long it is held after the relationship ends.
Reserve terms are negotiable. A business treated as a high-risk merchant should expect the size and the release period to be where most of the negotiation actually happens.
In practice
A reserve is the partner’s protection, not the operator’s asset to deploy. While it is held it cannot be spent, easily borrowed against, or counted as available liquidity, so the build-up belongs in the cash-flow model from day one — and the release schedule and the post-termination holding period matter more than the headline rate.
Example
An acquirer withholds a share of each day’s card settlement from a merchant and releases it six months later. For the first six months the merchant funds its business from the remainder while the reserve builds. From month seven, the month-one releases start arriving and the balance levels off — but that first six months’ worth stays with the acquirer until the relationship ends and the final holding period expires.
Commonly confused with
| Term | How it differs |
|---|---|
| Prefunding | Prefunding is money you place with a partner to be spent on payouts; a reserve is money the partner holds back so it can cover losses you might cause. |
| Escrow account | Escrow holds funds for a defined obligation between parties under agreed release conditions; a reserve secures one party against the other’s future losses. |
| Surety bond | A surety bond is a third party’s promise to pay if you do not; a reserve is your own cash already sitting in the counterparty’s hands. |

- PrefundingPrefunding means placing money with a payout partner or correspondent before transactions are sent, so the partner can release funds locally without waiting for settlement to arrive. The balance is drawn down as payouts are made and topped up before it runs out.
- ChargebackA chargeback is a forced reversal of a card payment, initiated by the cardholder’s bank rather than by the merchant. The money is taken back out of the merchant’s account under the card scheme’s dispute rules, whether or not the merchant agrees.
- High-Risk MerchantA high-risk merchant is a business an acquirer classifies as elevated risk because of its dispute rate, its regulatory exposure or its reputation — gambling, adult content, crypto, nutraceuticals and retail forex are the usual examples. The label is the acquirer’s, not a regulator’s.
- AcquirerAn acquirer is the institution that contracts with a merchant to accept card payments, submits those transactions into the card schemes, settles the merchant’s proceeds, and carries the acquiring-side financial exposure — including the cost of chargebacks the merchant cannot fund itself.
