Rolling reserves: how much is held, for how long, and how it is released

What a rolling reserve is

A reserve is money from your own sales that the bank or processor keeps back for a while instead of paying it out. In a rolling reserve, a percentage of each day’s card sales is held and then released after a set number of days, so new money keeps entering the reserve while older money leaves it.

Guidance written for US bank examiners by the Office of the Comptroller of the Currency (OCC) calls this a holdback: a percentage of the merchant’s sales deposits that the acquirer holds back to serve as a reserve against future exposure or to cover existing charge-backs. The same guidance says many acquirers set up reserves for merchants that pose high risk or have a history of charge-backs, and also where the product or service is delivered later than it is paid for.

A reserve is not a fee. The money is still yours: it reaches you later, less anything the provider is entitled to take from it under your agreement, such as charge-backs you could not otherwise cover.

Rolling, minimum and upfront reserves

Providers use different names. PayPal’s user agreement, last updated 14 September 2026, is one published example that separates the types, and says one or both may apply at the same time.

How much cash a reserve ties up

Two numbers decide the size of a rolling reserve: the percentage held and the number of days it is held. Once the first release arrives, the money released each day roughly matches the money added, so the balance levels off at about the percentage times your daily card sales times the holding days.

The table uses an illustrative business taking $1,000 a day in card sales, every day. Real sales vary, so treat the figures as an order of magnitude, not a forecast.

Scroll the table to see all columns.

Doubling the holding period doubles the cash tied up, just as doubling the percentage does. A lower processing fee with a longer reserve can leave you with less working cash than a higher fee with a shorter one, so compare both together.

Why a reserve is set and when it can change

Providers publish the kinds of factors they weigh. PayPal’s agreement lists how long you have been in business, whether your industry has a higher likelihood of charge-backs, your processing history, your credit history, your delivery time frames and your rate of returns, charge-backs, claims and disputes. Square’s help page names payment taken before goods or services are delivered, the charge-back rates in your industry and on your account, sporadic processing activity and being new to Square.

Terms can change during the relationship. PayPal’s agreement says it may place a reserve on a business account at any time if it believes there may be a high level of risk, and will notify you of new terms. Square’s page says accounts with reserves are reviewed after a minimum of six months. Stripe’s services agreement, last modified 28 September 2026, defines a reserve as collateral funds that Stripe holds and controls to satisfy liabilities or potential liabilities under the agreement.

These are examples of published terms on the dates shown, not a description of any other provider. In a high-risk offer, the reserve is part of the offer itself: ask for it in writing.

What to ask before you accept a reserve

• What percentage is held, and on which payments: card payments only, or every payment method?
• How many days is each amount held, and are they business or calendar days?
• Is it a rolling reserve, a minimum or upfront amount, or a combination?
• When and how is the reserve reviewed, and can it be raised or lowered without your agreement?
• What happens to the reserve if the account is closed or processing stops, and how long until the last release?
• What may be taken from the reserve, and how will you see each release and deduction?

Keep the written answers with the offer. A reserve that is described only in an email or on a call is hard to compare and hard to rely on.

Where Zolution shows it

Every proposal on Zolution states its rolling reserve as a percentage, from 0 to 100, and a hold period in whole days, shown as for example “10% held for 180 days”, or “No reserve”. It sits beside the fees, the settlement delay and the payout schedule, so you can see the cash-flow terms of competing offers together.

The reserve is provider-declared: Zolution does not verify it, set it or hold any funds, and the provider decides the final terms. Zolution Standard membership costs nothing.
