# I Will Build a Document Processing & OCR Automation Workflow

Stop wasting hours on manual data entry. Whether you are copying figures from invoices, pulling clauses from contracts, or extracting records from scanned documents, this service replaces that entire process with a reliable, automated workflow that delivers structured data in seconds.

Zinn Digital is a London-based software engineering team with over seven years of hands-on experience building production-grade document processing systems. We do not build throwaway scripts — we deliver clean, well-documented, production-ready code with proper error handling, so your workflow keeps running reliably at scale.

Here is what we build for you: an end-to-end automated pipeline that reads your source documents (PDFs, scanned images, invoices, contracts, forms and more), extracts the relevant data using OCR and AI-powered classification, and outputs it in whatever structured format you need — Excel, CSV, JSON, or direct database integration.

Our technology stack includes AWS Lambda for serverless automation, AWS Textract and Tesseract for OCR, Azure Document Intelligence, Google Cloud Vision, Python for processing logic, and database integration with PostgreSQL, DynamoDB and Excel/CSV. Every solution is built to match your specific document layout and output requirements.

WHAT IS INCLUDED
 Every tier includes a working Python-based extraction pipeline tailored to your document type and desired output format. The entry tier covers your core extraction logic. The Standard tier adds full source code delivery and an extra revision, giving you complete ownership and flexibility to extend the solution yourself. The Full tier adds further delivery time for more complex or multi-document scope and the same complete handover package.

WHO THIS IS FOR
 This service is designed for insurance companies processing policy documents, financial firms handling high volumes of invoices, legal practices managing contracts, healthcare providers extracting patient records, and any business that currently relies on manual data entry from documents.

HOW IT WORKS
 Share your sample documents and your desired output format. We review the scope, confirm requirements via order chat, and get to work. You receive a tested, working solution with documentation. If anything does not match your expectations, revisions are included.

Please message before ordering if your use case is particularly complex — we are happy to discuss scope and confirm the right tier for your project before you commit.
