Magento, add VAT nr to billing address

Question

It is possible in magento to add a VAT nr to your account but in belgium it's more common to add a VAT nr to your billing address.. is this possible in some kind of way ?

Answer 1

Yes, almost anything is possible as Magento is built with php and is completely open-source. But what you are requesting is not very easy, unfortunately. You will have to write a custom module to do this, and it's not an easy one to write.

Here are a couple possible options (I haven't tried them) that may get you started:
