The quick answer
In the demonstrated account, a $100 expense-category purchase order changed to Fully Billed after one saved bill showing a $50 expense line. The presenter used Actions > Make Copy on that bill and saved a second bill with a $50 line. The PO then listed both bills under Related Records > Receipts & Bills. This documents an observed sequence, not a standard billing recipe. Saving a copy for the same supplier charge can duplicate a payable or expense obligation; check the source lines and GL Impact before using any copied bill.
The screenshots use fictional person and company names and neutral example records. The workflow is a simulation of a 2023 source account's visible sequence. A separate 2026.2 account confirmed the form controls but did not reproduce the two-bill outcome. Forms, statuses, related rows, and actions depend on the account and role; the example does not establish final accounting impact, payment status, line-level allocation, or two distinct supplier invoices.
Before you start
This example begins with approved purchase order PO6 for Harbor Media Services. Its Expenses subtab has one Promotion row coded to 6100 Advertising for 100.00. A test Item Receipt 20 is already linked. The original account allowed that receipt on its expense PO; that behavior depends on account setup and is not a prerequisite you should assume elsewhere.
The two test bills use reference numbers 17 and 18 to distinguish them on screen. These are example references, not proof of two supplier invoices. In a real account, confirm the separate supplier invoice, search existing bills for the same reference and charge, and obtain accounting approval before saving a copy. The copied values can vary with form, role, workflows, and account configuration.
01. Review the expense purchase order
Open PO6. Its header shows Pending Bill, and the Bill action is available. In Items > Expenses, check the single 100.00 Promotion row and its 6100 Advertising account. This baseline matters because the first bill will be reduced to half of that amount.
02. Edit the sourced bill to $50
Click Bill, open Expenses, and edit the sourced expense row from 100.00 to 50.00. Commit the line with OK. The Expenses subtotal and header Amount now read 50.00. The change is on the bill draft, not on the original $100 purchase order.
03. Save the first bill
Enter the example reference 17 and click Save. The saved Bill 17 is Open for 50.00. In the original walkthrough, this first bill caused the $100 expense PO to show Fully Billed. That status did not mean the remaining $50 had been billed through the normal PO action.
04. Inspect the saved bill's Make Copy action
On saved Bill 17, open Actions and choose Make Copy. The source presenter used this because the PO was already marked Fully Billed after the first $50 bill. Make Copy begins a new vendor bill draft; it does not certify a remaining balance on the purchase order.
05. Review and save the copied bill
The copied draft carries the 50.00 Promotion expense. Before saving any real copy, confirm a separate supplier invoice, search for a duplicate bill, and check vendor, subsidiary, currency, date, tax treatment, expense account, amount, classifications, source line, and approval route. In this simulation, enter a separate test reference 18 and save, creating another Open bill displaying $50. Do not use a copy as a substitute for checking whether another charge is due. Saving a copy for the same charge can duplicate a payable or expense obligation.
06. Verify the purchase order's related records
Return to PO6 and open Related Records > Receipts & Bills. The example lists Item Receipt 20, then Bill 17 and Bill 18. Both bills are Open, each shows 50.00, and both rows have link type Order Bill/Invoice. These are header-level related-record rows; the label does not prove source-line matching, receipt requirement, a distinct supplier invoice, or correct GL and A/P postings. Open each bill to check those separately.
Common questions
Does Fully Billed prove the whole $100 expense was billed?
No. Fully Billed reflects the account's PO billing-status logic. In the demonstrated account, it appeared after a bill showing a $50 expense line. That display alone does not prove the $100 was correctly billed or posted, or that the vendor was paid. Compare each bill's amount, supplier reference, source line, approval, and GL Impact.
Is Make Copy the normal way to bill the remaining $50?
No. The source presenter used it after the PO appeared Fully Billed; the recording does not establish a standard remaining-balance method. A saved copy can repeat payable and expense data. For ordinary billing, use your account's approved PO-to-bill process and confirm how partial expense billing works for that transaction type. Use a copy only if the accounting owner has approved and tested the exception.
Do two Bill rows under Related Records prove the copy is correctly linked?
They prove that the example account displayed two bill rows on the PO. They do not establish line-level linkage, two distinct supplier invoices, correct approval, correct accounting, or absence of a duplicate charge. Open each bill and inspect its supplier reference, source line, amount, status, and GL Impact.
