What You'll Receive
Full Description
If your business is drowning in unstructured documents — invoices, forms, scanned PDFs, images — this service turns them into clean, structured, usable data. Using a combination of cutting-edge OCR frameworks, cloud AI APIs, and custom-trained models, you will receive accurate, reliable text extraction built precisely around your document types.
Whether you need to pull specific fields from invoices, extract table data, process handwritten forms, or build a fully integrated end-to-end application, this service covers the complete pipeline from raw input to structured output.
**What Is Included**
Every engagement begins with thorough research into your specific document types and extraction requirements. Images are preprocessed using OpenCV and Python to remove noise, correct skew, and maximise OCR accuracy before any extraction takes place. The appropriate algorithm or API is then selected and fine-tuned — drawn from a toolkit that includes AWS Textract, Azure Document Intelligence, Google Vision AI, Google Tesseract, EasyOCR, PaddleOCR, KerasOCR, LayoutLMv3, and ChatGPT Vision. Full source code is delivered with every order, alongside clear model documentation so your team can maintain and extend the solution.
For clients who need a complete solution, higher tiers include custom model creation, model validation and testing, cloud deployment, and ongoing performance monitoring — transforming the OCR pipeline into a production-ready system integrated with web, mobile, or desktop applications and databases such as Excel or Google Sheets.
**How It Works**
After placing your order, share your sample documents and describe the fields or data points you need extracted. The pipeline is then scoped, built, and tested against your real documents. You receive source code, documentation, and structured output in your preferred format.
**Who This Is For**
This service suits businesses and developers who need to automate document processing — including invoice parsing, form digitisation, receipt extraction, ID verification workflows, or any scenario where manual data entry from documents is slowing operations down. It is equally suited to individuals who need a one-off extraction script or a full scalable application.
**Why This Seller**
This service is built on hands-on expertise across the full OCR and document intelligence stack — spanning classical computer vision with OpenCV, deep learning frameworks including PyTorch and TensorFlow, and major cloud AI services. The ability to train custom OCR and document layout models (including LayoutLMv3) means accuracy is not limited by off-the-shelf tools. Support for over 20 languages and integration into mobile or web applications adds genuine versatility that generic data-entry services simply cannot match.

Frequently Asked Questions
Yes. Using tools such as AWS Textract, Azure Document Intelligence, and trained models like LayoutLMv3, the extraction can be scoped precisely to the fields you need — for example, invoice numbers, dates, totals, or named form fields.
Image preprocessing using OpenCV and Python is applied before extraction to correct issues such as skew, low contrast, noise, and poor resolution. This significantly improves accuracy on difficult source material.
Yes. The OCR tools used support over 20 languages, so multilingual documents can be processed. Please mention the language(s) involved when you place your order.
Yes. Table and key-value extraction is supported using trained algorithms and cloud APIs, making it suitable for invoices, receipts, structured forms, and similar document types.
Please share a representative sample of the documents you need to process and describe the specific fields or outputs you require. The more context you provide, the faster and more accurate the solution can be scoped.
Yes. Source code is included with every package, so you can run, maintain, and extend the solution independently after delivery.
Yes. The Enterprise package includes end-to-end application development and cloud deployment. If you need app integration on the Starter or Professional tier, please discuss your requirements before ordering so the scope can be confirmed.
The Starter package includes one revision. The Professional and Enterprise packages include unlimited revisions. Additional revision rounds can also be added as an optional extra.

Great freelancer who went above and beyond with the project.
Great job, open minded and proactive
Qazi's team has done a great job! From the very first contact throughout the entire project, they kept me in the loop about the development at all times and delivered according to the previously agreed deadlines. I'm very satisfied with the collaboration with Qazi's team - and equally satisfied with the outcome. If you are looking for outstanding AI developers, go no further. I can recommend Qazi's team without hesitation and will certainly use them in future projects again!
Working with Mlbench in the Data Science & ML domain was a great experience. Their professionalism and attention to detail were outstanding, coupled with excellent language fluency and quick responsiveness. The project was delivered on time, making the collaboration smooth and effective.
The result exceeded my expectations. Thank you very much, Qazi!
