Loop Returns offers special settings that make it easier for some tax tools to integrate, but many Shopify stores use Loop's default configuration. Zamp now supports Loop no matter how it is set up, including the out-of-the-box settings.
Zamp follows each order's full history through exchanges and returns and works out which period every positive and negative tax amount belongs in. It also detects which approach a store is using and applies the right logic automatically.
Sales tax that keeps getting better, without more work for you.
