Extracting Invoices From WhatsApp Photos With AI Vision (Apps Script + Google Sheets)

Short summary

A practical pipeline uses AI vision models to extract structured invoice data from WhatsApp photos, replacing manual data entry. The system routes extractions by confidence score: high-confidence goes straight to a Google Sheet, mid-range flags for human review, and low scores ask for a re-photo. At ~$40-100/month vs $2,000-4,000/month in labor, the ROI is immediate. Gemini Vision handles the first pass with Claude or GPT-4o as escalation for degraded receipts.

• •AI vision models extract invoice data from WhatsApp photos at $0.005-0.02 per receipt vs $2-4K/month in clerical labor
• •Confidence-score routing (>90 auto-append, 70-90 human review, <70 re-photo) prevents bad data from polluting the ledger
• •Gemini Vision as default first pass, escalating low-confidence cases to Claude or GPT-4o for degraded receipts
