The term **Rolling Reserve** stands for process of **securing** a **certain percentage** of the processed Transaction volume **for a defined period of time** to cover potential Risks, due to Chargebacks. In the IXOPAY platform the Rolling Reserve can be configured for each payment method individually, per [Merchant](https://documentation.ixopay.com/manual/docs/merchant/profiles) to be used in the Post Processing. Additionally the Rolling Reserve can be added per [Provider](https://documentation.ixopay.com/manual/docs/post-processing/provider) this parameter though is not used for further calculations.

To configure the Rolling Reserve

* Select the Payment **Method** from the drop-down. Leave empty to enable the Rolling Reserve for all payment methods.
* Fill in a **Percentage** number of Transaction Volume to be secured
* Fill in the number of **Days** Rolling Reserve should be secured.

The configured Rolling Reserve per Merchant can then be used for Merchant Settlement calculation within [Post-Processing Jobs](https://documentation.ixopay.com/manual/docs/post-processing/jobs) (e.g. on daily/weekly/monthly etc. base).

Alternatively Rolling Reserve per Merchant can be used within the [Fee Management](https://documentation.ixopay.com/manual/docs/connector/fee-management) to calculate line items per Transaction (Calculation Strategy **Rolling-Reserve from Merchant Configuration)**
