What is Intelligent Document Processing (IDP)?

Introduction

Intelligent Document Processing (IDP) is the answer to manual or cluttered document-related operations. 

As organizations generate and receive increasing volumes of paperwork and digital documents, from invoices to contracts, purchase orders, and compliance reports, the need to automate these workflows has become critical.

CFOs, procurement managers, and business owners see document handling as an unsustainable pain, and with reason. But, in a digital-first world, IDP aims to streamline and modernize how businesses extract, process, and manage data trapped in unstructured documents. 

In this article, we’ll break down what intelligent document processing is, how it works, its benefits, and use cases across industries.

What is intelligent document processing (IDP)?

Intelligent document processing is an advanced technology that uses artificial intelligence (AI), machine learning (ML), and optical character recognition (OCR) to automatically capture, extract, and organize data from different types of documents

Ingrained in IDP are the capabilities to understand context and learn from past mistakes while dealing with structured, semi-structured, or unstructured file formats like PDFs, images, emails, and scanned files.

From data to insights

At its core, these technologies bridge the gap between raw documents and actionable data.

And, naturally, the transformation of invoices, receipts, forms, contracts, and emails into searchable information raises the need for extreme accuracy and quality, especially for highly-regulated industries.

A qualitative system able to achieve high precision performances, can then be routed through business workflows.

In fact, the flexibility of IDP technology allows not just to interpret and classify text components, (supplier names, invoice numbers, amounts due, etc.), but also to integrate information into ERPs, CRMs, or accounting platforms with minimal manual intervention.

The result is a smarter, faster, and more reliable way to manage information across departments and functions.

How IDP works: key components explained

Intelligent document processing combines a series of technologies to automate document management from end to end.

The process follows a pipeline that mimics and enhances human interpretation of documents, but at scale, with far greater speed and precision.

Below are the key components that power IDP.

1. Document ingestion

The IDP journey begins with document capture and ingestion.

Documents can come from multiple sources: email attachments, scanned PDFs, mobile photos, FTPs, or cloud storage systems like Google Drive or Dropbox.

Procys, for example, works directly with email clients, accounting software, and ERP platforms, allowing seamless input without disrupting existing workflows.

2. Classification

Once documents are ingested, IDP systems automatically classify them based on their type, such as invoices, receipts, contracts, or forms.

Machine learning models are trained to recognize document structures and content patterns, which reduces the need for predefined templates.

This classification step is crucial for organizations handling large volumes of diverse documents, as it enables accurate routing and processing downstream.

This way, Optical Character Recognition (OCR) tools will have an easier time performing scanning and extraction.

3. Data extraction

This is where the power of AI meets OCR.

While traditional OCR can read characters and digits, IDP uses AI-driven algorithms to locate and extract specific fields such as invoice dates, supplier names, amounts, line items, or tax IDs.

Performing data extraction systems adapt to multiple layouts and languages, and can also identify handwriting or logos, enhancing its versatility.

4. Data validation

After extraction, IDP validates the information using predefined business rules or integrations with external data sources.

For example, the system can check whether an invoice number is duplicated, match vendor names against an ERP database, or verify totals against purchase orders: necessary steps to avoid human errors for AP and AR operations.

Validation helps prevent fraud, catch errors, and ensure compliance with accounting and regulatory standards.

5. Workflow automation and integration

Once the data is verified, IDP platforms can route it through business workflows for approvals, payments, reporting, or storage.

Integration with tools like QuickBooks, SAP, Microsoft Dynamics, Salesforce and other tools enables seamless handoff between systems.

In summary, proper and flexible systems offer native integrations without disrupting the businesses’ techstack to build powerful workflows tailored to their operations.

6. Continuous learning and optimization

One of the defining traits of intelligent document processing is its feedback loop.

Every correction made in the testing phases or by a user is used to retrain the model, improving accuracy and adaptability over time.

This learning capability allows the system to handle new document formats, layouts, and exceptions with increasing reliability.

IDP vs traditional OCR: what’s the difference?

At first glance, intelligent document processing (IDP) and optical character recognition (OCR) may seem similar.

They both involve reading information from documents. However, OCR is a foundational technology that IDP builds upon, while intelligent document processing takes automation and intelligence to a level far beyond what traditional OCR can achieve.

In summary

‍

While OCR may still have a place in legacy systems or for low-complexity needs, organizations seeking efficiency, scalability, and intelligence in document workflows are increasingly turning to IDP.

Benefits of intelligent document processing

Implementing intelligent document processing (IDP) delivers immediate and long-term advantages for businesses across industries. 

Below, we list out some of the most impactful benefits.

Time saving and operational efficiency

IDP drastically reduces the time spent on manual data entry and document handling.

By automating repetitive tasks like scanning, categorizing, extracting, and routing documents, employees can focus on higher-value activities.

This is particularly impactful for the automation of accounts payable (AP) and receivable (AR) processes, where delays in processing often create bottlenecks, and teams can save up to 80–95% of time spent on document-related workflows.

Improved accuracy and compliance

Manual processing is prone to errors: incorrect data entry, missed fields, and duplicate invoices can result in legal conflict and charges that damage the revenue, cash flow and, ultimately, the status of a business.

IDP ensures higher data accuracy through AI-driven validation and cross-checking mechanisms.

For industries like finance, tax administration, and travel agencies, where compliance with regulations is critical, IDP helps organizations maintain audit trails, meet deadlines, and avoid costly fines.

Scalability without additional headcount

As your document volume grows, scaling manual operations usually means hiring more staff; IDP removes that limitation. 

Its cloud-based infrastructure and learning models handle increasing loads without additional overhead, making it ideal for growing businesses or enterprises operating across multiple regions and departments.

Faster decision-making

With real-time document capture and structured data output, businesses gain access to actionable insights sooner.

Financial leaders can review payment cycles, procurement teams can spot vendor trends, and operations managers can track performance, all from a single source of truth.

This data availability enhances agility in decision-making and forecasting.

Enhanced customer and employee experience

When document-related processes are fast and error-free, internal teams experience less frustration, and customers enjoy quicker service, whether it's receiving an invoice, processing a refund, or handling a claim. 

IDP helps businesses meet expectations for speed, accuracy, and transparency, improving satisfaction across the board.
