Vat Calculations

On Invoicing a customer purchasing discounted items in checkout is taking the original figure to calculate the VAT so on an original price £15.00 (£12.50 + £2.50 VAT) if you discount to £10.00 (£8.33 + £1.67 VAT) on the invoice the amount will show as £7.50 + £2.50 VAT, so the total is correct but the VAT element is not. This error is on the individual item so the VAT for non-discounted items and shipping on the invoice is correct but the total obviously is not.
Any ideas how to correct this please?

Hello,

So the vat was not discounted?  In awocoupon->configuration, do you have 'calculate discount before tax' set to 'yes' ?

Hi thanks for the reply, i am using the free version in this site so the config isnt available, is there another way i can check ?

Hello,

The free version only does discount after tax.  To have it before you would need the pro version, or modify the free version directly.
