Python + Claude invoice clerk: reads invoices, checks VAT, flags unknown IBANs, waits for your approval before export. Not accounting advice.

Price & Timeline: $1,200 fixed | 5 business days from API access | 3 revision rounds Tech Stack: Python 3.11, Claude API (vision), Pydantic, pypdf, Google Sheets API, Docker

Demo Videos (sample data): Architecture walkthrough (demo): https://youtu.be/BuIoAV5DH4I Quick overview (Short): https://youtube.com/shorts/44zkoBe6HdQ The demo shows the vendor-check and approval flow on US-style sample invoices; VAT, IBAN and Claude vision steps are set up for your invoices during the build.

What you receive • Human approval before any payment or ERP export • Text extraction from PDFs (pypdf) and scanned invoices (Claude vision) • VAT line checks across multiple rates (amounts and totals must add up) • Unknown-IBAN hold: any IBAN not on your approved vendor list is held for your review (one fraud check, not full fraud detection) • Export to Google Sheets, CSV or your ERP/accounting system (JSON payload or webhook)

How it works

Kickoff & Credentials: Review your workflow requirements and API credentials.

Architecture & Pipeline Build: Build the Python workflow with PII masking and human approval steps.

Integration & Testing: Connect your ERP/accounting system and Google Sheets, and test edge cases on sample invoices.

Handoff & Deployment: Deliver source code, Docker setup, setup guide and a recorded screen walkthrough with captions.

You provide: the API keys and accounts (Anthropic, Google Sheets, your ERP or accounting system). Third-party fees and access approvals are on your side and can extend the timeline.

Not accounting or financial advice; your accountant makes the final call.
