MatchThree
Nothing leaves this machine

Find the invoices you should not pay yet.

Three-way matching for accounts payable, run entirely in this browser tab. Drop in the exports your system already produces and see, line by line, which invoices are clean and which are held — and exactly why.

  • Reads the PO, receipt and invoice exports you already have.
  • Separates what is ready to pay from what a person has to decide.
  • Never guesses — anything it cannot compute is named, not estimated.

No files needed — runs a small worked example so you can see the output first.

Load files

Drop your exports here — as many as you have

.csv and .xlsx. Files are read in this tab and never uploaded, and the match runs with your network off.

  • No account to run itLoad files, map columns and see the result without signing up.
  • Your files stay hereSpreadsheets are read in this tab and never uploaded. We count page visits; your files, mappings and results are never part of that.
  • Runs offlineTurn your network off and the match still runs. Nothing it computes needs a connection.
  • AuditableEvery output row traces back to its file, sheet and row number.

What comes out

One spreadsheet: a summary that records every rule you applied, the invoices ready to pay, the held ones with the exception that held each, the exception lines with ordered, received and billed side by side, and a source map tracing every row back to your file.

What it costs

$49 for a 14-day pass. Rerun and re-export as often as you need inside the window — fix a mapping, chase a receipt, run it again at no extra cost. No renewal, no subscription.

The rest of the bench

MatchThree is one of ten small tools built the same way: one job each, your own exports in, a decision you can defend out, nothing kept on a server.
