How is sales tax and VAT handled?

Calculated per location, per jurisdiction, at checkout. Every location is its own tax entity. Rates calculate at checkout by ship-to address, exemptions apply per customer, and the ledger records what was collected where. Multi-currency stores follow their market's rules. HQ never handles a location's tax, and a location never handles another's. Reports run by location and by period and export in one action. The honest note: the rules for your jurisdictions are yours to set; once set, the system applies them on every store, every time, and nobody at a location touches a rate.

What it used to cost you: A tax spreadsheet per state and a filing someone dreaded.

The feature is called Tax. It runs on the same rails as everything else here: one catalog, one price list, one cockpit, your name on the front.
