Sometimes a partial payment is paid to a Vendor to lock in a specific price for Product that will be purchased at a later date. An example of this might be prepaying $0.05 per gallon for Propane to the Vendor which locks in an actual Product cost of $1.05 per gallon.
- If an Add-on charge for partial Vendor prepay does not already exist, go to Setup / Inventory / Purchase Add-on Charges and select Add to create a new Purchase Add-on Charge. Enter an ID, Description, Rate Type, and Bill Type. The rate may be set as a Percent, Per Billing Unit, or a Flat Rate. This rate type is editable at the Purchase Order depending on the contract type being prepaid. The Classification is an optional setting. If used, this Add-on Charge defaults onto any line item containing a Product with a matching Classification. This new Add-on must be marked Included in Vendor’s Bill to influence the amount paid.

- Add a Purchase Order at Inventory / Purchase Orders.
- Mark the Prepay option on the Purchase Order.
- Select the Product being purchased and set the $/Unit as the amount being prepaid.

- Double-click in the Add-On field. If the Add-on Charge does not automatically show in the grid, double-click <Charge ID> and select the partial prepay Add-on Charge.
- Set the Rate as the unpaid amount and set Calculate as to Per Billing Unit.
- Choose Calculate. This displays the unpaid portion that will later be billed for this Purchase Order. Note that the new $/Unit for this line item displays the full amount of the unit price so the Product’s cost will be correctly updated.

- Save the Purchase Add-on.
- The Purchase Order now displays the amount booked. Selecting Apply calculates the amount of Prepay.
- The PO can now be received against on a Purchase Receipt as normal. The Add-on Charge follows through based on the Purchase Order set up and quantity received.
- The Purchase Receipt can then be imported into a Purchase Invoice. The Add-on Charges set up on the Purchase Order follow through the Purchase Receipt into the Purchase Invoice.
