A scan asks Shopify's own tax engine what it would charge for each kind of buyer, in each country you sell to, for each kind of product. Every scenario is a calculation only: nothing is ordered, paid for, or changed. Each answer is compared against a versioned EU and UK rate table and reported with the inputs and the raw response behind it. Findings say what kind of claim they make, and a discrepancy is never reported from one reading.

• Prices every scenario with Shopify's own tax engine, ordering nothing
