Invoice Data Extraction with a Vision LLM API: 60 Invoices, Every Field Scored, $0.78 per Thousand
We ran 60 invoices, half of them degraded like phone scans, through Qwen 3.8 27B's vision input over an OpenAI-compatible API with a JSON schema on the output. Vendor, customer, invoice number, currency, every amount and every line item came back right on all 60. The one thing that failed, half the time, was a date written with slashes, and the fix is two lines of code, not a bigger model.
