💡 SaaS Idea: Receipt-to-JSON with line items API + SMB expense inbox

API and web inbox where users email or upload receipts; system extracts merchant, taxes and individual line items, categorizes, and syncs to QuickBooks/Xero or exports CSV.

  • Other HN/Reddit posts (“Show HN: OCR Benchmark Focusing on Automation”, “Mistral OCR”) consistently mention line-item-level accuracy as the missing feature in existing scanners.
