When I raise an invoice I can only enter the unit price to two decimal points.

This has logic as the to decimal points equate to pence. However we often quote prices in round pounds say £14.00 for a meal including VAT. Net of VAT this is £11.66 repeater which I can't enter.

Ideal would be to be able to enter price including VAT or alternatively have ability to enter net price with more decimal points.
