RefundMath

Stop over-refunding. Calculate exact partial refunds with proper discount allocation.

When you issue a partial refund on an order that used a discount code, Shopify doesn't redistribute the discount correctly across returned items. This leads to over-refunding customers. RefundMath solves this by reading the original discount allocations stored in your order and calculating the exact refund amount. Features include automatic discount redistribution, tax credit calculation, multi-quantity item support, and real-time refund preview.

• Real-time refund preview before processing
• Automatic tax credit calculations included
• Multi-quantity item support for complex refunds
