Reserve

Also called merchant reserve, security reserve, reserve account, rolling reserve

Money your acquirer holds from your settlements as collateral against future chargebacks, refunds and losses.

What it is

A reserve is collateral. Your acquirer withholds a portion of your money to cover potential future liabilities: chargebacks, refunds, fines, and the losses that follow if the business closes with unfulfilled obligations. It is not a fee, and it is your money, though the timing of its return is governed by your merchant agreement. Three structures dominate. A rolling reserve withholds a percentage of each day's or each batch's settlement, commonly reported at 5 to 10 percent, held for a rolling period, commonly 90 to 180 days, then released on a rolling basis. An upfront or capped reserve holds a fixed dollar amount, funded at boarding or accumulated from settlements until a cap is reached, then held static. A minimum balance reserve requires a floor to be maintained in the settlement account. Reserves are rarely required for genuinely low-risk card-present merchants, sometimes required in the medium tier such as subscription billing, travel, online electronics and health and beauty, and commonly required in the high-risk tier, where a rolling reserve is standard. A reserve can also be imposed after boarding, unilaterally, if your risk profile changes: chargeback ratio rising, volume spiking beyond the application, a change in what you sell, or a monitoring program identification. That is the version merchants find shocking, and it is generally permitted by the merchant agreement they signed.

Why it matters to your business

Never sign a merchant agreement without knowing, in writing, whether a reserve applies, on what formula, for how long, and what triggers a change. If a salesperson tells you there is no reserve, get that in the approval documentation, not in a text message. If a reserve is imposed on you later, ask for three things in writing: the contractual provision it relies on, the calculation, and the release schedule. Then calendar the release date yourself, because nobody else will. And once a year, if your chargeback history has been clean, put that history in writing and ask for a step-down. It is never automatic and it is frequently granted to merchants who ask. This is education, not legal advice. Reserve terms are contractual and enforceable; if a reserve is threatening your business, that is a conversation for an attorney who does payments work.

Where it gets contested

The fight is over disclosure and release. Reserves imposed at boarding and disclosed in writing are simply the price of risk, and a merchant can decide whether it works. Reserves imposed later, calculated by a method the merchant cannot audit, and released on a schedule that keeps slipping, are the most common source of serious merchant complaints in this industry. The acquirer's position is defensible in principle: they carry the loss, they set the collateral, and a merchant whose behavior changed is not the merchant they underwrote. The merchant's position is equally real: a 10 percent rolling reserve on a business running thin margins is a working capital event that can close a company that has done nothing wrong. The genuinely unresolved area is release after account closure. Standard practice is to hold reserves for a period after termination covering the chargeback window, often six months or longer. Getting a final release requires follow-up, and the number of merchants who simply forget is not small.

How to check it yourself

Search your merchant agreement for the word reserve and read every occurrence. Then look at your last three settlement reports and confirm that gross sales minus fees equals what actually hit your bank. Any unexplained gap is a reserve or a hold, and you should have it named in writing.
