If you did not receive an invoice from the vendor when you received the items and accounts, you can use this process to enter the invoice when it arrives.
Recalling a Purchase Order
Before receiving a purchase order you should recall and review it using any of the following methods:
Updating Prices on a Purchase Order
Once the purchase order has been recalled it should be compared against the purchase order. If there are any price differences do not update the line items on the purchase order to reflect the actual price per part if the part has already been received. This could cause the value of your inventory to become incorrect.
Add a new Account line instead and associate it with a cost of sales account. Give it a description of Price difference. Set the quantity to 1 and enter the difference between the purchase order total and the invoice total in the Price field. You can also associate it with a department, job or dispatch if desired.
Creating the Bill
Once that has been completed, click the Save and Bill icon at the top of the screen. Select Yes when asked if you would like to mark the purchase order as Billed. Enter the invoice number on the resulting screen to create an invoice in your accounting software for ALL the items on the purchase order.
