What is Document Processing and How to Automate It?

Table of Contents

We can’t deny the fact that the volume, variety, and complexity of documents that businesses deal with are constantly increasing. Manual document processing methods are struggling to cope with the increasing data influx, leading to inefficiencies, errors, and delays.

There’s an immediate need for an automated document processing workflow. But let’s first understand about document processing, its evolution, intelligent document processing, etc. in detail. 

What is Document Processing?

Document processing is defined as the process of converting unstructured or semi-structured data from physical or native digital documents to digital format that keeps the original layout, text, and pictures of the document intact. 

Evolution of Document Processing

In the constantly changing landscape of document processing, new technologies have been crucial in reshaping the way businesses handle information.

Phase 1: Manual Document Processing

It was the phase where documents were handwritten, the information was manually extracted and feeded into the system. 

There were various challenges businesses faced with manual document processing.

  1. It was a laborious process.
  2. It was time consuming.
  3. It was error-prone.
  4. It was hampering business’ efficiency and growth as well. 

Phase 2 – Optical Character Recognition (OCR) Technology: Rule-based Automation/Template-based Solution

During this phase, Optical Character Recognition (OCR) technology emerged as a prominent solution. It enables computers to identify and transform printed text into data interpretable by machines.

In this template-based or completely rule-based solution, businesses must initially train the model on various invoice types, as the placement of invoice numbers can vary. For each new supplier, a new template needs to be defined. And, this was the biggest challenge business were facing in rule-based automation.

Phase 3 – AI for Data Extraction and Verification from Documents (Intelligent Document Processing)

It is a template-free solution where an ML model is trained to work synergistically with OCR, utilising NLP and computer vision. OCR is employed to extract raw data from documents, while ML/Extractive AI is leveraged to derive meaning from the raw text.

The models are trained in such a way that even for a completely new invoice, they attempt with reasonably high accuracy to accurately extract and interpret the data. This is achieved by assuming the level of proximity from the corpus of knowledge obtained during the training set.

Thus, in such a context, exploring how document processing works and how you can automate it becomes essential.

AI solutions such as KlearStack, powered by machine learning(ML) and natural language processing(NLP), can efficiently analyze, extract, and interpret data from diverse documents, irrespective of format or structure. Want to see how? Here’s the attached video link.


This capability of AI has made document processing intelligent and enhanced the accuracy and processing speed. 

What is Intelligent Document Processing?

IDP is a workflow automation technology that leverages AI and ML to scan, read, extract, categorise, and organise data into the editable/accessible format. 

The technology can process a variety of documents such as Invoices, Purchase Orders, Recipets, Bank Statements, etc. This includes physical documents scanned and digitizes or eletronic documents.

How Does Intelligent Document Processing Work?

Document processing involves a series of steps to extract unstructured data and convert it into digital formats. The journey typically includes pre-processing, data classification, data extraction, validation, and integration. 

Let’s walk through each step:

Step 1: Pre-processing: Firstly, documents are scanned or uploaded. Pre-processing involves tasks like noise reduction, image enhancement, and format standardisation. 

For instance, imagine a stack of handwritten customer feedback forms. The pre-processing step would involve converting the scanned images into clear, standardized digital files.

Step 2: Data Classification: The second step involves classifying documents into categories based on content or purpose. 

For example, incoming documents might be categorized as invoices, contracts, bills of lading, packing lists, bank statements or customer inquiries. This classification sets the stage for streamlined processing.

Step 3: Data Extraction: In this step, relevant information is extracted from the documents. Optical Character Recognition (OCR) technology can extract raw text from images. This extracted textual and visual content is furthur interpreted by an AI/ML layer.

For example, consider a batch of invoices. Data extraction software would identify and extract fields like invoice numbers, dates, and item descriptions.

Step 4: Data Validation: Extracted data is cross-checked for accuracy and completeness. 

In the case of invoice processing, the document processing system might verify that the calculated totals match the sum of individual items. Any discrepancies are flagged for human review.

Step 5: Integration: Processed data is integrated into storage systems or APIs for further use. 

For example, in a customer relationship management (CRM) system, customer details extracted from forms would be integrated to update records or trigger follow-up actions.

Here’s an example of a document processing journey: 

KlearStack works with a company that generates 200,000 sales transactions each day to eliminate 98% of manual work and optimize its sales document processing , enhance efficiency and customer experience.

  • Data processing: When a customer shows interest, their inquiry documents are scanned and uploaded into its standardised digital data.
  • Data extraction: The KlearStack system extracts and creates sales quotes or contracts with accurate prices and details.
  • Data validation: The sales team reviews and adjusts the document, and if needed, managers or legal teams give their OK. The customer gets the document by email, signs it electronically, and sends it back.
  • Integration: The signed document is saved in the system, easy to find and refer to whenever needed.

This end-to-end journey illustrates how document processing takes unstructured documents and transforms them into actionable, structured digital information. 

This efficiency not only saves time and reduces errors but also empowers businesses to make informed decisions and enhance their operations.
