There is no option to disable VAT.

As a non-VAT registered business, my invoices technically shouldn't make any mention of VAT, and setting it to 0% is technically wrong.

Invoicing even puts an (empty) "VAT Registration No" at the bottom of every invoice with no way to turn it off.

Please make VAT optional so it can be turned off and businesses who aren't VAT registered can use Invoicing efficiently.
