EU VAT
Validate EU VAT numbers live at checkout and zero-rate cross-border business sales. If the validation service is down, checkout keeps working.
Sales Tax
Charge the exact tax rate for every zone.
Set a tax rate for each zone, and every shopper sees the exact total at checkout.
Accurate Tax
Tax rates matched to each order’s destination.

Tax Profiles & Rates
Tax profiles, rates, rules and geo zones.
Tax profiles, rates, rules and geo zones work together, so each shopper pays exactly the tax their own region sets.
-
Tax Profiles
Group products by how they’re taxed, as standard, reduced or exempt, and assign the profile once per product.
-
Tax Rates
A rate ties to a profile and a region, so one region’s rate never reaches another region’s order.
-
Geo Zones
Regions are built from the countries, states and areas you ship to, so every checkout uses your own map of regions.
-
Tax Rules
Where a jurisdiction charges more than one tax on the same sale, a rule stacks the rates instead of picking just one.
A missing tax profile gets flagged before your first order
The setup guide checks that your store has a tax profile and links you straight to the screen to add one, so tax is in place before your first order.
- Every tax rate change applies going forward only; an order already placed keeps the rate it was charged
- Tax is worked out again on your server when the order is built, so the tax billed always comes from your own rates
- The order record keeps the tax charged as its own line, next to the price and the shipping charge
- The setup guide flags your store if it has no tax profile before you take your first order
