What You'll Receive
Full Description
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.
Zinner Quality Guarantee
Every Zinner is reviewed and approved before joining the platform.
All services are backed by our quality assurance commitment.
Your payment is protected until you approve the delivered work.

Frequently Asked Questions
We work with PDFs, scanned image files (JPG, PNG, TIFF), invoices, contracts, forms and similar unstructured documents. If you are unsure whether your document type is supported, message us before ordering and we will confirm.
We can produce Excel, CSV and JSON outputs as standard. We also support direct database integration with PostgreSQL and DynamoDB. Let us know your preferred format when placing your order.
You will need to share sample documents representative of what you want processed, along with a description of the data fields you need extracted and your desired output format. The more context you provide, the faster we can get started.
Source code is included in the Standard Build and Full Pipeline tiers. The Core Extract tier delivers the working solution and documentation. If source code ownership is important to you, we recommend the Standard Build or above.
Once we deliver, you review the output against your requirements. If something does not match what was agreed, request a revision via the order chat and we will address it within the included revision allowance. Additional revisions can be purchased as an add-on.
Quite possibly, yes. Please message us before ordering with details and a sample if possible. We will assess the scope and confirm the right tier or discuss a custom arrangement if needed.
For solutions that use AWS services (Lambda, Textract, S3, DynamoDB), you will need an AWS account. We will guide you through what is required. If you prefer a purely local Python solution, let us know and we will factor that into the approach.
Customer Reviews
See what our customers say about this Zinn
It was great to work with Serdar. I would definitely work with him again.
I've worked with Serdar on a few projects now over the past seven months or so and it has been fantastic. He is a total professional – knows his subject matter extremely well, is a great communicator, requires little guidance after a conversation, delivers work on time (and even ahead of schedule on this last project), is able to solve tricky problems, and is a pleasure to interact with. I could not recommend Serdar more!
Great work on this project, both projects have been very smooth and I am looking forward to more future projects. Thank you !
I’ve had the pleasure of working with Serdar on multiple projects, and he’s consistently been amazing to work with. Once again, he delivered the project on time and within budget. He’s extremely responsive, very patient with all the tweaks and revisions we requested, and he always makes sure we’re fully satisfied with the final product. Highly recommend!
Thank you for your help with creating the code for data extraction from our PDFs. This is a big help and saves us a lot of time. I look forward to working with you again in the future!
