Do you know how to permanently change VAT and fiscal year? Some of you might need it right now!
Both changes are applied on the server, please have a look at the screenshot below.
1. Fiscal Year > General Tab > hit the bar below Division/s
2. Tax > Financial Tab > Permanently change Tax. Please remember that there is also a tax field on the Contact Type Client. It provides the flexibility to set different Tax values per customer and therefore over-ride the Server side default value.
