Good morning Graham,

Can't figure out the profit margin pls look at attachment 1,first one shows when selling 1 item selling price ,cost price and percent profit is right.

attachment 2 shows difference when selling same item twice where the cost stays the same but selling price and profit margin goes up,

this doesn't happen with non vat products see attachment 3 and 4 pls explain how I can work out what my true margin is

kind regards

Amin
