OpsProof Local AP Scanner

Local-first duplicate-payment risk scanner for accounts payable payment-run exports.

Chinese guide: README.zh-CN.md.

What This Is

OpsProof Local AP Scanner is a static browser tool for reviewing demo, redacted, or local AP CSV exports before a payment run goes out.

It is designed for bookkeepers, SMB controllers, finance operations teams, and AP consultants who want an explainable HOLD / REVIEW / CLEAR queue without sending payment data to a cloud service.

The source is public so AP teams can inspect the local/no-upload scanner boundary before using it with their own export shapes.

The first path requires no Python, no ERP login, no bank connection, and no server.

Try It

1. Download or clone this repository.
2. Open index.html directly in Chrome or Edge.
3. Click Load demo samples and run.
4. Review HOLD / REVIEW / CLEAR.
5. Download the CSV or HTML report.

You can also inspect the bundled demo-data report first:

• English sample report
• Chinese sample report

Live entry points:

• Live scanner and website: tools.simplezion.com
• Free proof pack: Payhip free pack
• Paid self-serve bundle: AP Control Evidence Bundle
• Setup service: AP CSV mapping and first-run review

Supported Inputs

• Current payment-run CSV.
• Optional paid-history CSV.
• Optional vendor alias CSV.
• Header-only checks before sharing any rows.
• English AP field names.
• Chinese AP field names, including common China-style export headers such as 供应商名称, 往来单位名称, 采购发票号, 本次付款金额, 业务日期, and 付款申请单号.

Included Checks

• Exact duplicate invoice in the current run.
• Normalized invoice match after punctuation, spacing, and case cleanup.
• Same vendor + same amount + near-date review.
• Duplicate current-run row signatures.
• Historical paid comparison when paid-history data is provided.
• Vendor/payee alias review.
• Local, explainable anomaly signals that never override the deterministic queue.

Privacy Boundary

This repository is designed around a local-first review path:

• No ERP login.
• No bank connection.
• No account login.
• No cloud upload for the scanner workflow.
• No storage writes.
• Network APIs are blocked inside the page after startup.

Use demo, sample, redacted, or header-only exports first. Do not paste private vendor, bank, tax, payroll, customer, or payment-card data into any public issue.

Tests

Run:

npm test

The smoke tests validate English and Chinese field mapping, Chinese supplier-name normalization, HOLD / REVIEW / CLEAR output, report generation, and the local signal evidence contract.

Open-Core Boundary

This repository is the open-source proof layer. It is intentionally useful on its own, but it is not the full commercial AP review workflow.

Paid/commercial work may include deeper review packs, field-mapping service, first-run readiness notes, private customer-specific mappings, advanced rule packs, consultant workflow material, and support.

See Commercial Boundary.

Not Accounting Advice

This tool is not an accounting approval workflow, audit opinion, fraud guarantee, payment approval system, ERP connector, bank connector, or legal/tax service. It produces review evidence for human AP review.
