I will build an ai batch invoice and receipt extractor using nextjs and ocr


About this gig
Are you tired of spending countless hours manually typing invoice and receipt data into spreadsheets?
I will build a production-ready AI Batch Invoice & Receipt Extractor web application powered by Next.js 14 and state-of-the-art Multi-Modal AI (Google Gemini 3.8 Flash & OpenAI).
Unlike generic OCR tools that hallucinate numbers, my solution features a Deterministic Math Engine that verifies Qty × Unit Price == Line Total, flagging calculation errors in red for human review.
KEY FEATURES:
Batch Document Processing: Upload and extract 10+ invoices simultaneously.
Deterministic Math Engine: Eliminates AI calculation errors.
Human-in-the-Loop Review: Interactive side-by-side zoomable document canvas.
Instant CSV / Excel Export: Ready for accounting software & ERP.
Multi-Format Support: PDF, JPG, PNG photos, and scanned receipts.
Clean Next.js 14 & TypeScript architecture with optional database setup.
WHY WORK WITH ME?
Tested, enterprise-grade architecture (no unverified code).
Super fast turnaround time (ready in 2-5 days).
Clear communication and post-delivery support.
Please feel free to message me before ordering to discuss your custom requirements!
