I got a bit confused with the profit margins between HQ and SO, and then realised that my HQ is set up to deduct VAT from my cost price in order to obtain the margin, but all our cost prices on the system so far have no VAT in them, it would be a standard thing to get our cost prices exclusive of VAT. I have noticed in configuration where it says "Use VAT" it is ticked, Do i need to take this tick box away? And if i do that will i upset any of my other settings, i use the store tax tab to set my VAT for branches etc.
Thanks
