The module screen in the PrestaShop 9 back office, arranged in tabs.
VAT number. The module's seven tabs, and the first of them: format check, VIES check, blocking when the European service does not answer, hiding the field without a company, number required in the European Union only, and countries reserved for businesses.
Checks. The address of the scheduled task to call once a day, the VAT numbers that became invalid, and the evidence kept on the latest orders.
