Tipalti matching error remittance detail missing purchase order reference

• A Tipalti invoice or remittance item is unmatched and the error names a missing PO reference. - The supplier invoice PDF shows a PO number but the Tipalti record does not. - Auto-matching worked for other invoices from the same vendor but failed for this one.

Find the approved purchase order first. Search purchase orders for the vendor and amount and note the exact PO number, including any prefix. Expected: one open PO matches the vendor, amount, and date range.

Open the unmatched invoice or remittance record. Check the PO reference field; it is blank, or it holds an internal request number instead of the PO number. Expected: the mismatch is visible in the reference field, not in the amounts.

Enter the exact PO number. Copy the number from the purchase order record rather than typing it from the supplier paperwork, which often truncates prefixes. Expected: the field validates and the vendor on the PO matches the vendor on the invoice.

Re-run matching. Trigger matching again and watch the status. Expected: the invoice moves from unmatched to matched, and any remaining hold names a different reason such as quantity or tax.

Document supplier-submitted cases. If the supplier sent remittance detail with no PO because none was issued, attach the approval or exception note to the record instead of adding a false reference. Success check: the record is matched or exception-approved, with the PO number or the exception visible in the audit history.

Problem query: Tipalti matching error remittance detail missing purchase order reference

TL;DR: Automatic matching needs the purchase order reference in the remittance or invoice record; without it Tipalti cannot tie the payment detail to the open PO and the item sits unmatched. Add the exact PO number from the approved purchase order to the invoice record, re-run matching, and confirm the PO value and vendor match. If the supplier submitted without a PO, record the approved exception instead of inventing a reference.
