A vendor invoice is the bill a vendor sends for stock you've already received — Rundoo calls recording one "vouchering," and it's the step that hands the PO over to accounting to get paid.

In the POS mode, open the Orders left tab, then the Vouchered top tab — that's where unpaid vendor invoices live, between Received (stock is in) and Paid (bill is settled).

The vendor invoice lifecycle

The right-hand stretch of the Orders top-tab strip is the invoice lifecycle: Received → Vouchered → Paid. Each tab is a stage a PO moves through once the truck has shown up.

• Received — stock landed and on-hand counts are updated, but the vendor's invoice hasn't been recorded yet. The PO sits here waiting on invoice details.
• Vouchered — invoice recorded. The PO's amount owed is now on your books as an unpaid bill. This is the handoff point to your accounting side.
• Paid — payment recorded. The bill is settled and the PO is done.

Each tab shows a live count. The Vouchered tab doubles as your "what do I owe vendors" queue — every open row is an invoice still to pay. See Tracking what you owe below for reading it.

Receiving stock is a separate step that happens before vouchering — see Order receipts for how to log what actually came off the truck. This Rundoc picks up where that one leaves off.

Vouchering a received PO

Open a PO from the Received tab and you'll see the PO detail with an empty Invoice panel on the left and a disabled Voucher button at the bottom right.

The Invoice panel has four fields, all required:

• Invoice date — the date on the paper invoice from the vendor. This is the date the bill hits your GL, so it drives due-date math and period reporting. Use the date the vendor stamped, not today.
• Due date — when payment is due. Rundoo doesn't auto-compute this from your vendor's terms — copy it from the invoice.
• Invoice Number — the vendor's invoice ID. Required for vouchering; also how Rundoo dedupes against the same vendor billing you twice for the same shipment.
• Pay to — who the check goes to. Defaults to the PO's vendor; change it if the invoice is payable to a parent entity or a different billing address on the same vendor record.

The Order details panel on the right holds Add fee or discount — a free-form line for freight, early-pay discounts, handling charges, or any other invoice-level adjustment that isn't tied to a single line. Use this when the invoice total doesn't match the sum of line costs. Line-level cost corrections (wrong unit price on a specific product) belong on the receiving side — see Order receipts for those.
