Two ways to hold the same risk
A processor holds a reserve because it may have to pay refunds, chargebacks or fines after the merchant has already been paid. The reserve is a buffer against that delayed exposure. How the buffer is built matters as much as its size, because it decides how much working capital the merchant loses and for how long.
A rolling reserve is time-based. A percentage of each day's or month's sales is held, and each held amount is released after a fixed period. The balance keeps moving: new money comes in, old cohorts go out. A capped reserve is balance-based. The processor withholds a percentage of sales until an agreed total is reached, then stops collecting and keeps that balance in place.
The cash profile side by side
Take a merchant processing $100,000 a month with a 10% reserve.
| Month | Rolling, 180 days | Capped at $30,000 |
|---|---|---|
| 1 | $10,000 | $10,000 |
| 3 | $30,000 | $30,000 (cap reached) |
| 6 | $60,000 | $30,000 |
| 7 onward | about $60,000, cohorts release | $30,000, no new holds |
The rolling reserve keeps taking 10% of every payout forever, even though the balance stops growing. The capped reserve costs more in the first months and then leaves payouts untouched. You can model both structures in the rolling reserve calculator.
Which structure fits which risk
Rolling reserves suit exposure that moves with volume, such as future delivery in travel or ticketing, where refunds scale with recent sales. Capped reserves suit exposure that is roughly fixed, such as a one-time concern about a new merchant without processing history. Processors also use upfront reserves, a lump sum before processing starts, and minimum balances that override release dates.
Questions to ask before signing
- Is the hold rolling, capped, upfront or a combination?
- Is release daily, weekly or monthly, and from which date does the clock start?
- Can the processor change the rate or period without notice, and what triggers a review?
- What happens to the balance after termination, and for how long can it be held?
- Will the reserve be reduced after a period of clean processing?

Frequently asked questions
What is the main difference between a rolling and a capped reserve?
A rolling reserve holds a percentage of sales for a fixed period and releases each cohort later, so it never stops withholding. A capped reserve withholds a percentage until an agreed balance is reached, then stops collecting new holds.
Which reserve is better for cash flow?
A capped reserve usually costs more cash in the first months and less afterwards. A rolling reserve takes a constant share of every payout. The better choice depends on volume, growth and how long the merchant expects to process.
Can a processor change reserve terms later?
Many agreements allow it after a risk review, for example when chargebacks rise or the business model changes. Check the agreement for review triggers, notice periods and conditions for reducing the reserve.
