If giving discounts, the system should be able to handle that items are not sold below cost price. example

purchase cost ex vat is =€100

20% Markup = €20

client purcahses for €120 ex vat

Vat = €27.60 on €120

Total cost Client €147.60

now if we apply a 40% discount on the €147.60 Discount = €59.04

Cleint new purchase price is €88.56

Business is loosing money now.

phorest records the sales as below.

Sales €72 ex vat

Vat €16.56

the system should not allow sales to go through at below cost. it should allow item to be sold at €100 ex vat what the business bought the product for.
