# InStore_Refund

The InStore\_Refund module provides functionality to process returns.

InStore\_Refund is a [product or core module](/instore/implement-instore/modules/working-with-instore-modules.md) that acts as a modifiable wrapper for the InStore core application. To learn more about module configurability, contact the [support team](https://support.commercetools.com/).

This module processes previously prepared return Carts. To create a return Cart, use the [InStore\_Cart](/instore/implement-instore/modules/instore-cart.md) module.

## Capabilities

The InStore\_Refund module handles the following InStore functions:

- Receives a Cart of returned items for a refund.
- Connects to your Project to determine if items are eligible for return. Eligibility is based on factors such as activity since the original purchase, elapsed time, and other criteria.
- Sends and retrieves data about a consolidated exchange Cart when the value of the returned item is more than the value of the replacement item.
- Analyzes the distribution of tenders used in the original purchase and calculates their respective percentages for a refund.
- Reviews administrative parameters to understand the your business policies for refunds.
- For refunds where the original payment used:
  - Cash: queries the user to determine if the cash drawer has sufficient funds; if not, issues a voucher.
  - Credit or debit card: checks with the payment provider if the original card can accept refunds.
  - Stored-value card or voucher: issues a voucher with the refund amount.
- Instructs the user on the amount of cash to refund, if applicable.
- Sends tender types and totals information to the receipt builder.
- Sends return information to the original Order record in your Project.
- Retrieves, formats, displays, and prints [refund receipt](/instore/implement-instore/receipts/refund-receipt.md) information.

The actions that a user can perform depend on their given [role](/instore/use-the-instore-center/store-roles.md) and the [parameters settings](/instore/customization/administration-parameters.md) that you define in the InStore Center.
