How to enter a VAT only invoice

You may on occasion have reason to enter a VAT only invoice, for example form a courier or an Insurance company.

You need to do this across 2 lines. 

First you need to figure out the Net amount relating to the VAT.

To do this, divide the VAT amount by the corresponding VAT Rate and multiply by 100.

Example VAT amount is 230, Vat Rate is 23%   230/23 *100 = 1000

Enter the first line item as 1000 net with VAT at 23%

Enter the second line item as -1000 net with VAT at 0%

The invoice total will then be only the VAT amount.
