Collecting tax IDs with Quaderno Checkout

Quaderno will automatically display a tax ID field on your checkout link. Generally this is an optional field in the checkout. If your business is based in Bulgaria, Cyprus, Spain, Croatia, Italy, or Portugal, the tax ID will be required for customers in your own country if you are collecting full billing details from your customers. The tax ID would be optional for customers in other EU countries.
Quaderno will automatically apply reverse-charge where applicable.
