Accounting teams deal with a constant flood of financial documents receipts, invoices, purchase orders, bank statements often in inconsistent formats and from multiple vendors. Manually processing these documents is time-consuming, error-prone, and difficult to scale. Even with digital systems, much of the input still arrives in scanned PDFs or image-based formats that require human review. This is where Optical Character Recognition (OCR) and Intelligent Document Processing (IDP) come in automating the extraction of financial data and reducing repetitive tasks so teams can focus on analysis, compliance, and decision-making. 

The Intelligent Document Processing (IDP) market is experiencing rapid growth, projected to increase from $860 million in 2021 to over $4.15 billion by 2026. This surge is driven by the growing demand for automation and stricter regulatory requirements. At the same time, the OCR market is also expanding significantly, with forecasts estimating it will reach $29.54 billion by 2029, growing at a compound annual rate of 15.3%. Key factors fueling this growth include the widespread adoption of mobile OCR, greater accessibility for visually impaired users, and increased use across sectors like finance and e-commerce. Meanwhile, emerging technologies such as AI-driven automation, predictive analytics, machine translation, and cloud-native platforms are playing a major role in accelerating adoption especially in document-heavy fields like legal services.

Automating Invoice Processing & Data Entry

Invoices are essential to day-to-day accounting operations, but processing them manually introduces delays and risks of human error especially when formats vary across vendors. OCR technology converts scanned or image-based invoices into machine-readable text, while IDP uses pre-trained models to extract structured information such as vendor names, invoice numbers, line items, amounts, and payment terms.

Advanced systems go a step further by validating extracted data against purchase orders and payment records, automatically flagging discrepancies like duplicate invoices or mismatched totals. This automation helps accounting teams reduce cycle times, improve accuracy, and maintain better control over cash flow. 

Agilent Technologies, a global leader in life sciences and diagnostics, faced challenges in processing a high volume of invoices manually, leading to delays and increased operational costs. To address this, Agilent implemented an automated solution combining Robotic Process Automation (RPA) with OCR and Machine Learning technologies. This integration enabled the company to automatically extract and process invoice data, significantly reducing manual effort and improving accuracy. As a result, Agilent achieved faster invoice processing times, enhanced compliance, and substantial cost savings, demonstrating the transformative impact of automation in financial operations.

Automatically separate taxable from non-taxable line items

When accountants process invoices, receipts, and expense reports, distinguishing taxable from non-taxable items is a routine but error-prone task. These documents often contain line items like freight charges, software licenses, promotional giveaways, or services that may or may not be taxable depending on local laws, exemptions, or purchase context. Manually flagging each line item requires checking regulatory codes, vendor classifications, and invoice notes, a time-consuming process especially at scale.

Intelligent Document Processing (IDP) uses OCR to digitize receipts or invoices, and applies AI models trained on tax logic to classify line items based on context. It can detect whether a shipping charge qualifies for tax, identify if a food expense is deductible under travel policies, or flag tax-exempt purchases based on item description and jurisdiction. This not only reduces errors during tax preparation but also ensures compliance with changing tax codes and improves audit readiness.

Siemens implemented automated invoice validation with tax rule-based engines across its global procurement operations. The system used OCR to scan invoices and identify item-level taxability based on local VAT regulations. This helped reduce compliance risks, saved countless hours in manual validation, and improved consistency across international filings.

For example Arieotech implemented an IDP system integrating advanced OCR with Microsoft's Document Intelligence, enabling the automated extraction and classification of data from various formats, including PDFs and Excel files. This automation led to a 40% reduction in data extraction time and minimized errors associated with manual processing. The system effectively distinguished between taxable and non-taxable items, ensuring compliance and streamlining the auditing process.

Auto-match Invoices, Purchase Orders, and Payments

Matching invoices against purchase orders (POs) and payment confirmations is one of the most critical and time-draining tasks in accounts payable. The traditional approach requires finance teams to manually verify details like quantities, prices, supplier names, and delivery dates across multiple documents, which can easily lead to missed discrepancies or delayed approvals.

OCR and Intelligent Document Processing (IDP) tools streamline this workflow by extracting structured data from invoices, POs, and remittance slips, then automatically comparing values to check for mismatches or duplicates. Advanced systems can flag anomalies (like billing overages or unauthorized vendors), trigger exception handling, and reconcile payments without human intervention. This not only accelerates payment cycles but also reduces fraud risk and improves audit readiness.

Datamatics' notes in their case study for a client there that is a large European manufacturer, operating in sectors like Energy and Marine, faced challenges in processing over 140,000 invoices annually, split between 90,000 PO-based and 50,000 non-PO invoices. Manual processing led to delays and inefficiencies. To address this, the company implemented Datamatics' AI-enabled RPA solution, TruBot, along with the intelligent data capture tool, TruCap+. This setup automated the end-to-end accounts payable process, including the three-way matching of invoices, POs, and goods receipt notes. As a result, the company achieved a 25% improvement in overall efficiency and productivity, improved cash management through real-time data visibility, and enhanced data security, leading to increased partner and supplier satisfaction.

Automating Bank Statement Data Extraction with IDP and OCR

In the realm of accounting and financial management, the manual extraction of data from bank statements is a time-consuming and error-prone task. Intelligent Document Processing (IDP) combined with Optical Character Recognition (OCR) technologies offers a solution by automating the extraction of key financial data from bank statements. These systems can accurately capture information such as transaction dates, amounts, descriptions, and balances, converting unstructured data into structured formats suitable for analysis and reporting. By reducing manual intervention, businesses can accelerate reconciliation processes, minimize errors, and ensure compliance with financial regulations.

The integration of IDP and OCR into financial workflows not only enhances efficiency but also provides real-time visibility into cash flows and financial health. Automated data extraction ensures that financial records are up-to-date and accurate, facilitating better decision-making and strategic planning. Furthermore, these technologies can adapt to various document formats and languages, making them suitable for global operations. The result is a streamlined financial process that supports better financial oversight and operational efficiency.

Hitachi Payment Services, a prominent provider of white-label ATM solutions in India, faced challenges in processing over 3,000 bank statements monthly, each varying in format and structure. The manual categorization of transactions was labor-intensive, taking up to 2–3 hours per statement. To address this, Hitachi implemented Docsumo's AI-powered IDP solution. By leveraging advanced OCR and machine learning algorithms, Docsumo automated the extraction and classification of data from diverse bank statement templates. This transformation reduced processing time from hours to minutes, achieving 99% data extraction accuracy and saving over 6,000 man-hours per month. The successful deployment of Docsumo's solution underscores the transformative impact of IDP and OCR technologies in financial data management.
