Updated Shopify product tax code mappings

More products land in the right tax category automatically, which means fewer filing issues and more accurate tax.

As Zamp's tax team expands product taxability coverage, the mappings between Shopify product categories and Zamp product tax codes need to keep up. The team audited roughly 11,000 Shopify product types and remapped them.

Shopify products are now matched to more precise tax codes automatically.
