There are a number of ways to manage receiving stock and invoices at different times on one purchase order.
Suggestion 1
▪Leave the original PO on Received status until all invoices have come in. Ensure the stock on the PO has the correct cost (as far as you know).
▪Add Expense Orders for each of the 3 invoices, linked to the Received PO. These will then roll into creditors and will ultimately provide the cost of goods for the original PO.
▪FINISH the original PO at $0.
Suggestion 2
▪Leave the original PO on Received status until all invoices have come in. Ensure the stock on the PO has the correct cost (as far as you know).
▪Make the creditor payments as Prepayments in Creditors, noting the main PO number and relevant Invoice number in the Payment Comment field.
▪When all 3 invoices have come in, amend the Received PO to FINISH, with the 3 invoice numbers in the Vend Inv field and/or Notes field, and apply the prepayment credits against the invoices.
Suggestion 3
▪Leave the original PO on Received status until all invoices have come in. Ensure the stock on the PO has the correct cost (as far as you know).
▪Add Expense Orders for the 3 invoices and pay them as normal in creditors. Do not link these to the original PO.
▪Add a negative expense order against the Creditor for the value of the 3 invoices to create a credit.
▪Finish the original PO at the correct cost and then apply the credit to clear the debt.
