How to record the differences

Hi Tony Li You would set up a product and service for the item that you purchase from your supplier/sell to your customer and enter the same amount in the sales price/rate.and cost fields. You would also create another product and service and call it discount and don't enter any amounts. When you create the supplier bill you will select the product and service which will populate with the amount you're purchasing the item for. You would then on the next line enter the discount product and service and enter an minus amount ad the amount of discount you're receiving. You would then have to create an invoice and enter the product and service.
