Payment Matching Assistant Starter Kit: CSV Invoice-to-Bank Exception Queue

Manual payment matching looks simple until customers omit invoice references, pay multiple invoices in one transfer, pay partially, or send amounts that do not tie cleanly to the invoice list.

Payment Matching Assistant Starter Kit is a downloadable CSV-first workflow for testing invoice-to-payment matching logic without giving a tool access to your bank account or accounting system.

It flags review candidates such as:

- Invoice reference matches.

- Name + amount + date-window matches.

- Amount/date-only weak matches.

- Possible partial payments.

- Possible bundled payments or overpayments.

- Currency mismatches.

- Late payment candidates.

- Invoices with no payment candidate.

- Payments with no invoice candidate.

Included in the download:

- Python matching script.

- Sample open invoice CSV.

- Sample bank/payment CSV.

- Sample custom-column mapping file.

- Configurable rules file.

- User guide.

- Column mapping quickstart.

- Buyer fit checklist.

- Demo walkthrough.

- Sample CSV, Excel, JSON, and HTML output reports.

v1.1 adds custom column mapping and an Excel workbook output, so buyers can adapt invoice and bank/payment exports without manually renaming every column.

This is a Starter Kit, not a hosted SaaS product. It does not connect to bank feeds, payment gateways, or accounting systems. Buyers should be comfortable running a Python script locally or adapting CSV exports into the sample format.

Risk boundary: This product is a validation assistant, not a replacement for accounting controls, professional reconciliation, audit review, or source document review. It does not guarantee detection of every payment, duplicate, mismatch, or accounting error.
