What a rolling reserve does
Under some merchant agreements, a provider retains part of processed funds for a period to cover defined risks such as future disputes or refunds. Amounts may be released on a rolling timetable, subject to the agreement and any continuing hold rights.
A reserve is different from a one-off security deposit, delayed settlement or an ad hoc account hold, although each affects available cash.
Read the reserve schedule as a cash-flow document
| Term | Question |
|---|---|
| Percentage or amount | What is retained from which transactions? |
| Holding period | When should each retained amount become eligible for release? |
| Release method | Is release automatic and where is it reported? |
| Review triggers | What can increase, reduce or end the reserve? |
| Termination | What happens to retained funds after the account closes? |
Model realistic scenarios
Apply the proposed reserve to several months of real or forecast sales, including peak trading and refund periods. Keep the result separate from processing fees: retained cash may be returned later, but it can still create a serious working-capital need.
Questions to get answered in writing
- Which contract clause creates the reserve?
- What statement or dashboard shows additions and releases?
- Can the provider change the reserve, and on what evidence?
- How are chargebacks and refunds taken while a reserve exists?
- Who reviews the arrangement and how can the merchant request reconsideration?
Compare the complete risk terms
A lower headline rate may not compensate for a reserve that the business cannot fund. Compare underwriting conditions, settlement, guarantees, termination and support alongside processing price.
