Purchase Order Three-way Match

How to use Purchase Order Three-way Match

A payable invoice should agree with the approved order and the supplied receiving evidence. Compare all three sides without treating a missing receipt as zero or silently removing orphan rows.

1. Enter approved PO lines, authorized receiving records and invoice-line metadata in one currency.
2. Set explicit absolute quantity and unit-price tolerances and inspect all line and orphan findings.
3. Resolve differences against original documents before an accountable human approves a payment outside this tool.

Good to know

• No returns, tax, freight, currency conversion, source-document authenticity or accounting approval is inferred.
• Quantities accumulate by exact PO/line; every invoice unit price is checked separately. Tolerances are not percentages or invoice-value limits.
• Each input field is limited to 8,000 UTF-16 characters and each exact-header CSV to 100 data rows. Quoted commas/newlines and doubled quotes are supported. Unsupported controls and unpaired surrogates are refused. Decimal magnitudes are at most 999,999,999 with a smallest nonzero magnitude of 0.000000001; exponents are refused and whole counts are checked exactly. Rational results show at most 18 fractional digits and an ellipsis when more remain.
• Editable Markdown and long-form CSV both retain all summary metrics, context, detailed findings, entered source rows and scope limitations. CSV columns are Record type,Section,Source row,Field,Value; spreadsheet-looking text is apostrophe-prefixed. These are review artifacts, not proof of source truth or a completed real-world task.
• Runs deterministically in this browser. No AI, API, vendor connection, upload, outreach, calendar change, payment, storage or background monitoring. Use authorized pseudonymous records; inspect exports before sharing.
