Frequently asked questions

What is the difference between the free guide and the €10 guide?

The free guide gives the short answer and what to do. The full guide explains everything, with diagrams, examples, the table by country or by case and a spreadsheet to apply it to your store or your business.

How do I receive the guide?

When you pay, by e-mail: the PDF and the spreadsheet. It reads well on a phone.

And if the rules change?

The guide you buy is the one dated with its version, with the rules in force at that time, and it does not include later updates.

Do the guides replace an adviser?

No. They explain the general rules in plain language; every case has its nuances. For yours, a 15-minute call or one of the consultations.
