I run a store in Germany. I have a question about the order summary page. How can I add a field to allow the customer to enter their tax identification number?

Thank you in advance for your help! 🙂

You can check this thread , it is actually quite clear on the subject.

In a few words:

1. On simple plans it is not possible 

2. Generally it is not only about VAT number , it is also about including VAt into domestic sales and Excluding VAT for intra EU cross border sales.


We can offer to you a solution which is based on draft order (see below) . We will collect and validate VAT number and make all necessary calculations.
