Change customer or customer location on sales invoice
In Visma Net, you can change the customer or customer location on a sales invoice, even when it already has lines. If you want to change the customer or customer location to one with a different VAT calculation, on a sales invoice with lines, consider the following to make sure the VAT calculation is changed as well.

Make sure the Recalculate VAT when customer is changed on document check box in the Organisations (CS101500) window is selected. See also: Recalculate VAT when customer is changed on document.
