Using the Calc. Net icon

If only the Gross amount for a transaction is known, but VAT should be calculated, enter the Gross amount in the Net field and click on the Calc. net icon. 

This will take the value in the Net value field and convert it to a Gross figure made up of a new Net and VAT amount using the VAT percentage on the item line.

Therefore, in an item line with S VAT, £100 entered in Net will be converted to £83.33 Net, £16.67 VAT and £100.00 Gross.
