When we create Estimates it contains several line items for expenses and then the items being sold. At the bottom of the Estimate we have SUBTOTAL which we assume is our expense items and the cost of the inventory items, then there is MARKUP which is our gross profit on the items being sold.
When we add a discount it reduces the SUBTOTAL which is our cost, what we need is it to reduce our MARKUP so that we know exactly what our margin is on the job after the discount.
Is there a way to do this?
Any suggestions or advice will be greatly appreciated.
