So what you actually need is an entirely different process for setting and handling VAT inclusive prices... but that's a lot more complex and not supported by all the Accounting /ERP systems we integrate with... so overall this is something that seems to have more complexity than initially seems
The main issue here is that VAT is calculated on the line value, not the price. So you get potential rounding issues - especially where you might have decimal prices and decimal quantities. i.e if you add VAT to a price and then multiple by quantity you dont always get the same answer as taking the line value (which is net price times qty) and applying VAT afterwards.
