After an order is generated you may find that you need to edit the price or quantity of the products before processing payment. To do this properly you will want to edit the order products on the order record. The order and invoice records will then update to match. If you update anywhere else you may have issues applying payment.
1. Open the Product you wish to modify.
Double click the blank space on the record to open quickly. The arrows show good places to do this.
2. Change the price of the item
You may want to simply change the price of an item for an individual and you can override the price for this product on this order only.
3. Adjust the quantity .
You do not need to override the price to do this, but you can also do this with a price that is modified. If the customer orders 2 items you can change it to 1 for example.
4. Add a manual discount.
You can also keep the sales price at the default but show the customer that they are receiving a discount by putting in a manual discount which will reduce the total amount of the order.
