Please note that the app currently supports collecting and handling the customer’s VAT ID. However, Company ID / registration number, Company address, Company name and local tax ID cannot be configured or handled at the moment.

Important sidenote:
Shopify’s native Company VAT number field may require Shopify Tax for EU/UK VAT validation. Shopify Tax is free up to Shopify’s yearly sales threshold, but after that Shopify may charge a transaction-based fee.
This is controlled by Shopify, not by our app. Our app can only read and forward the VAT number once Shopify makes it available on the order/customer data.
Optional workaround: in Tax services, Shopify also offers Basic Tax, which is free, and in some cases VAT ID collection can work with Basic Tax as well.
How it works:
Step 1 – Customer enters VAT ID
The customer can simply enter their VAT ID during checkout, and Shopify VIES-validates it in real time.
Please note: if VAT ID validation is not included in your selected tax service option, customers may still be able to submit any entered value, not only a VIES-validated VAT ID.
The Postal code (ZIP) and Country/region must be entered first for the VAT number field to appear:
Step 2 – VAT ID is saved to the customer
The VAT number is saved under Customer → VAT number
This works both for checkout orders and manually created admin orders.
Step 3 – We send the VAT ID to iDoklad ✅
We send this VAT number to the invoicing system as part of the customer contact details, so it appears in the correct place on the document.
