What Is Intelligent Document Processing? IDP Explained for Finance Teams

February 22, 2026

Intelligent document processing (IDP) is the use of AI to automatically extract, classify, and structure data from documents—regardless of format, layout, or quality. Unlike basic OCR, which simply converts images to text, IDP combines optical character recognition, natural language processing, and machine learning to understand what a document is, what data matters, and how to organize it for downstream systems. It is the technology category that turns unstructured documents into structured, usable data without manual intervention.

Lido takes an AI-first approach to document processing that delivers IDP capabilities without the traditional complexity. There are no templates to build, no models to train, and no months-long implementation cycles. Finance teams upload documents in any format—invoices, purchase orders, medical claims, bills of lading—and Lido extracts structured data on the first pass. Companies like ACS Industries have replaced enterprise IDP workflows with Lido, processing over 400 purchase orders per week across every document format without a single template.

How intelligent document processing works

IDP follows a five-stage pipeline, and each stage uses AI differently. Understanding this pipeline is the fastest way to evaluate whether an IDP tool is genuinely intelligent or just OCR with a marketing upgrade.

  1. Document ingestion. Documents enter the system from email, cloud storage, SFTP, or direct upload. The IDP platform normalizes inputs—converting PDFs, scanned images, photos, and even faxes into a processable format. This step handles image quality issues like skew, low resolution, and noise.
  2. Classification. The system identifies what type of document it’s looking at: invoice, purchase order, receipt, bank statement, medical claim. Traditional IDP tools use document structure patterns and layout matching to classify. AI-first tools use language understanding—they read the document and infer the type from context, which means they handle unfamiliar layouts without retraining.
  3. Extraction. This is where the core value lives. The system pulls structured data fields from the document—vendor name, invoice total, line items, dates, patient IDs, whatever the use case requires. Legacy IDP tools map extraction zones on templates. Modern AI-first approaches use contextual understanding to find data wherever it appears on the page, even when the layout changes.
  4. Validation. Extracted data gets cross-checked against business rules, lookup tables, or downstream databases. Does this vendor exist in the ERP? Does the invoice total match the sum of line items? Does the PO number correspond to an open order? This step catches errors before they propagate into accounting or operations systems.
  5. Integration. Validated, structured data feeds into downstream systems—ERPs, accounting software, databases, spreadsheets. The output format depends on the workflow: JSON for APIs, CSV for spreadsheets, or direct writes to systems like QuickBooks, NetSuite, or SAP.

Why traditional IDP tools are losing ground to AI-first approaches

Traditional IDP platforms—ABBYY FlexiCapture, Kofax, UiPath Document Understanding—were built for a world where AI couldn’t understand documents on its own. They compensated with template engines, classification taxonomies, and supervised training pipelines that required hundreds of sample documents per type. The result: powerful extraction capability locked behind months of implementation and six-figure budgets.

That tradeoff made sense when it was the only option. It no longer does. Modern large language models can read a document, understand its structure, and extract data accurately on the first attempt—no templates, no training samples, no dedicated IT team managing a rules engine. The “intelligent” part of intelligent document processing has moved from the platform to the AI model itself.

This shift matters most for mid-market companies and growing finance teams. A 50-person accounts payable department at a Fortune 500 company can justify a 12-month ABBYY implementation. A 5-person AP team processing invoices from 200 vendors cannot. AI-first IDP tools like Lido close that gap—delivering enterprise-grade extraction accuracy with a time-to-value measured in hours, not quarters. For teams evaluating alternatives to template-based platforms like Nanonets, the question isn’t whether AI-first approaches work. It’s why you’d still invest in building templates at all.

Intelligent document processing vs. OCR vs. RPA

These three technologies overlap enough to cause confusion, but they solve fundamentally different problems.

  1. OCR (optical character recognition) converts images of text into machine-readable text. That’s it. OCR doesn’t know what a document is, what fields matter, or how to organize the output. It turns a scanned invoice into a block of text—but it doesn’t extract the invoice number, vendor name, or line items into structured fields. For a deeper look at this distinction, see our guide on what OCR data extraction actually involves.
  2. RPA (robotic process automation) automates repetitive clicks and keystrokes across applications. RPA bots can open emails, download attachments, copy data between fields, and trigger workflows. But they don’t understand documents. An RPA bot can move data from cell A1 to a form field, but it can’t look at a new invoice layout and figure out where the total is.
  3. IDP sits above both. It uses OCR as one component (the text recognition layer), but adds classification, contextual extraction, and validation on top. It doesn’t just see text—it understands document structure and meaning. Many companies try to stitch together RPA plus basic OCR as a budget IDP alternative. This works for simple, consistent documents—the same invoice template from the same vendor, every time. It breaks the moment formats vary, which in accounts payable and healthcare means it breaks constantly.

The practical test is format variability. If your documents come in one or two consistent formats, OCR plus scripting may be enough. If you’re handling dozens or hundreds of formats—which is the reality for most AP teams, CPA firms, and logistics companies—you need genuine IDP capability.

Where intelligent document processing delivers the most value

IDP creates the largest ROI in industries where document volumes are high, formats are inconsistent, and manual data entry is a bottleneck that directly impacts cash flow or compliance.

  1. Accounts payable. AP teams receive invoices from hundreds of vendors, each with a different layout, format, and set of fields. Manual entry is slow and error-prone. IDP extracts invoice headers, line items, tax amounts, and PO references automatically—even from vendors the system has never seen before. This is the single largest IDP use case by volume, and it’s where invoice OCR technology has the most direct impact on operational efficiency.
  2. Healthcare. Insurance claims, explanation of benefits (EOBs), medical records, and prior authorization forms come in wildly inconsistent formats. IDP handles the layout complexity—extracting patient data, procedure codes, billing amounts, and provider information from documents that legacy OCR systems consistently misread.
  3. Logistics and supply chain. Bills of lading, waybills, customs declarations, and shipping manifests are mission-critical documents that still move through supply chains as PDFs, scanned images, and even faxes. IDP extracts shipment details, container numbers, and weight declarations without requiring templates for every carrier and freight forwarder.
  4. Financial services. Loan applications, bank statements, tax returns, and supporting documentation arrive in every format imaginable. IDP extracts and cross-references data across multiple documents in a single application package—matching income figures on a pay stub against declared income on a loan form.
  5. Legal. Contracts, court filings, and discovery documents require extraction of specific clauses, dates, party names, and obligations. IDP accelerates contract review and due diligence by pulling structured data from documents that would otherwise require hours of manual reading.

What to look for in an IDP platform

Not every tool marketed as IDP actually delivers on the promise. These are the criteria that separate genuine intelligent document processing from rebranded OCR.

  1. Extraction accuracy without templates. The defining test. Upload a document the system has never seen before and measure extraction accuracy on the first pass. Template-dependent tools score well on trained document types and poorly on new ones. AI-first tools like Lido maintain accuracy across unfamiliar formats because the model understands document context, not just layout coordinates.
  2. Classification capability. Can the system automatically determine what type of document it’s processing? This matters when documents arrive in mixed batches—invoices, credit memos, and receipts in the same email attachment.
  3. Time to value. How long from purchase to first production extraction? Traditional IDP: 3–12 months. AI-first IDP: hours to days. If a vendor quotes a “6–8 week implementation,” you’re buying a template engine, not an AI.
  4. Document type coverage. How many document types does the platform handle out of the box? Some tools specialize in invoices only. Others, like Lido, handle invoices, purchase orders, medical claims, shipping documents, receipts, bank statements, and more—all without configuration. Ask about the long tail: what happens with a document type the vendor hasn’t explicitly built for?
  5. Human-in-the-loop handling. No IDP system is 100% accurate on every document. What matters is how the platform handles low-confidence extractions. Does it flag uncertain fields for human review? Does it learn from corrections? A good human-in-the-loop workflow turns exceptions into a quality control step rather than a bottleneck.
  6. Integration options. Extracted data needs to go somewhere—ERP, accounting software, database, spreadsheet. Look for native integrations with your existing systems, plus API access for custom workflows. Using ChatGPT or general-purpose AI for document processing might seem like a shortcut, but it lacks the integration layer that moves data into production systems automatically.
  7. Total cost of ownership. Per-page pricing sounds simple, but watch for hidden costs: implementation fees, template-building charges, model training hours, and minimum commitments. Calculate the all-in cost per document over 12 months, not just the per-page rate.
  8. Scalability. Can the platform handle volume spikes—month-end closes, audit season, open enrollment periods—without degradation? Cloud-native architectures handle this better than on-premise installations.

How Lido approaches intelligent document processing

Lido delivers IDP outcomes—accurate extraction, structured output, downstream integration—through an AI-first architecture that skips the traditional IDP complexity entirely. There are no templates to configure, no training sets to assemble, and no classification taxonomies to maintain. You upload a document, define the fields you need, and Lido extracts.

This isn’t a theoretical advantage. ACS Industries replaced a UiPath-based document processing workflow with Lido and now processes over 400 purchase orders per week. Every document format is handled automatically—no templates built, no exceptions manually coded. The formats that broke their previous RPA pipeline work on the first pass with Lido.

Relay uses Lido to process over 16,000 medical claims—healthcare documentation with complex multi-column layouts, variable fields, and inconsistent formatting across payers. This is exactly the kind of document variability that traditional IDP tools require extensive template libraries to handle. Lido handles it natively.

A CPA firm processing 3,500 audits per year came to Lido because their documents arrive in “thousands of formats.” That’s not an exaggeration—audit documentation includes bank statements, invoices, receipts, tax forms, and supporting documents from every client, vendor, and institution their clients work with. Template-based extraction is mathematically impractical at that scale. AI-first extraction is the only approach that works.

For finance and operations teams evaluating IDP platforms, the question has shifted. It’s no longer “do we need intelligent document processing?” It’s “do we need the traditional enterprise version of it, or can we get the same results without the implementation overhead?” Lido exists because the answer, increasingly, is the latter.

Frequently asked questions

What’s the difference between IDP and OCR?

OCR converts images of text into machine-readable characters—it sees the text but doesn’t understand it. IDP adds classification, contextual extraction, and validation on top of OCR, turning raw text into structured data fields like invoice numbers, totals, and vendor names. Lido uses an AI-first IDP approach that handles both the recognition and the structuring in a single step, without requiring templates or training.

What document types can IDP handle?

Modern IDP platforms handle invoices, purchase orders, receipts, bank statements, medical claims, bills of lading, contracts, tax forms, and virtually any structured or semi-structured document. The key differentiator is whether a platform needs templates for each new type. Lido handles new document types automatically—its AI reads and understands documents without pre-built templates, which is why customers use it for documents in thousands of formats.

Does IDP require template setup?

Traditional IDP platforms like ABBYY and Kofax require templates—you map extraction zones for each document layout, which can take weeks per document type. AI-first IDP tools eliminate this entirely. Lido requires zero template setup. You define the fields you want extracted, and the AI locates them regardless of where they appear on the page or how the layout is structured.

How accurate is IDP on scanned documents?

Accuracy depends on scan quality and the IDP platform’s preprocessing capabilities. High-quality scans (300 DPI or above) typically yield extraction accuracy above 95%. Lower-quality scans, faxes, and photos introduce more variability. Lido combines advanced OCR preprocessing with AI-powered contextual extraction, which means it can often infer correct values even when individual characters are ambiguous—because it understands what the field should contain based on document context.

What industries benefit most from intelligent document processing?

Accounts payable, healthcare, logistics, financial services, and legal see the highest ROI from IDP because they process high volumes of documents in inconsistent formats. Any industry where manual data entry is a bottleneck—and where errors have financial or compliance consequences—benefits from IDP. Lido serves customers across all of these verticals, from AP teams processing hundreds of vendor invoices to healthcare companies handling thousands of medical claims.

How does Lido’s IDP approach differ from template-based tools?

Template-based IDP tools require you to build and maintain extraction templates for each document layout—a process that takes weeks per type and breaks when vendors change their formats. Lido uses an AI-first approach where the model understands documents contextually, extracting data accurately from any layout on the first attempt. This means zero setup time, no template maintenance, and consistent accuracy across documents the system has never seen before.
