# Calculate refund based on received

Sometimes customers do not ship back all products in a return. Manually calculating the correct refund amount can be complicated and lead to errors.

When clicking Refund on the ParcelWILL management page, you can select the specific quantity for each item you wish to refund, or click Refund based on items received. ParcelWILL automatically calculate the correct numbers for you.

When you select partial quantities for calculation, the system automatically adjusts the subtotal, discount, and tax to ensure the final refund is accurate.

Note: This feature is for calculation convenience only. All requested products in the return will be marked as "returned" in the system once processed.
