Technologies Used in Receipt Data Extraction

Transforming unstructured receipt images into structured data depends on four key Artificial Intelligence (AI) technologies working together. These include Optical Character Recognition (OCR), Machine Learning (ML), Natural Language Processing (NLP), and Table-Type Recognition. These technologies enhance accuracy and efficiency in data extraction, enabling businesses to automate processes and gain valuable insights.

‍

Optical Character Recognition (OCR)

OCR converts printed text from receipt images into machine-readable data. It extracts characters and words, transforming unstructured data into the structured JSON format. This process automates data entry, reduces manual labor, and minimises errors in financial records. While traditional OCR didn’t always use “AI” in the modern sense, state-of-the-art OCR today frequently relies on machine learning and deep learning models.

‍

Key Points:

  • Text Conversion: Translates printed text into digital data.
  • Data Structuring: Organises extracted text into usable formats.
  • Automation: Eliminates the need for manual data entry.

‍

Machine Learning (ML)

ML enhances data extraction by learning from vast datasets of receipts. They recognise patterns, adapt to diverse formats, and handle complex layouts without manual configuration. Over time, these technologies improve accuracy and can identify anomalies and new receipt designs, ensuring consistent data quality.

‍

Key Points:

  • Pattern Recognition: Learns from data to improve extraction.
  • Adaptability: Handles different formats and layouts.
  • Continuous Improvement: Gets smarter with more data.

‍

Natural Language Processing (NLP)

NLP interprets and understands human language within receipts. It identifies and categorises essential data like merchant names, transaction dates, item descriptions, quantities, prices, and total amounts. NLP manages abbreviations, slang, and variations in terminology, ensuring extracted data is accurately labeled and ready for integration into your accounting systems.

‍

Key Points:

  • Language Understanding: Makes sense of textual data.
  • Data Categorisation: Labels key details correctly.
  • Terminology Management: Handles linguistic nuances.

‍

Table-Type Recognition

Table-Type Recognition specialises in extracting detailed data from tables within receipts, such as line items and their associated details. It preserves the relationships between data points, maintaining the structure of the original receipt. This software enables precise data capture for inventory management, expense analysis, and financial reporting.

Modern methods for table recognition often involve ML or deep learning techniques (often at the intersection of computer vision and NLP).

‍

Key Points:

  • Detailed Extraction: Captures line-item specifics.
  • Relational Context: Maintains data relationships.
  • Structured Data: Facilitates accurate reporting.

‍

Rule-Based Systems (Complementary Layer)

Although these various sub categories of AI OCR are powerful tools in receipt data extraction, certain situations benefit from predefined, rule-based logic. Rule-based systems impose business rules, formatting standards, or known constraints on the extracted data. By applying these fixed rules, companies enhance data consistency. They also identify anomalies that AI might overlook and ensure the data aligns with internal standards and regulatory requirements.

‍

Key Functions:

  • Business Logic Enforcement: Ensures data adheres to known patterns (e.g., tax rates or formatting standards).
  • Quality Control: Flags discrepancies and validates extracted data against set rules.
  • Hybrid Approach: Complements AI-driven methods to refine accuracy and reduce errors.

‍

How These Technologies Work Together

  • OCR lays the foundation by converting images of printed text into digital data.
  • ML builds on this by recognising patterns and adapting to new receipt formats, enhancing accuracy over time.
  • NLP interprets and categorises the extracted text, ensuring it makes sense within context.
  • Table-Type Recognition structures the data, preserving relationships for seamless integration into your systems.

Modern receipt data extraction systems combine OCR, ML, NLP, advanced table recognition, and rule-based logic to handle diverse receipt formats. This combination helps them overcome layout inconsistencies and complexities. As a result, they provide structured, detailed data that supports accounting, expense management, and strategic decision-making.

Employee expense reimbursement - An example of Structured Data Output in Action

Imagine a company using a receipt OCR API to process hundreds of receipts submitted by employees for expense reimbursement.

‍

Scenario: Automating Expense Management

Before Structured Data: Employees manually input details like total amounts, dates, and merchant names into the company's expense management system. This process is prone to errors and delays.

After Structured Data:

Receipts are scanned, and the OCR API extracts key data into a JSON format.

The data is automatically uploaded into the expense management software, categorising expenses and calculating totals.

JSON Example:

{
  "receiptNumber": "10310",
  "date": "2024-09-25",
  "merchantName": "Chipotle",
  "totalAmount": 14.42,
  "taxAmount": 0.82,
  "lineItems": [
    {"name": "Chicken Bowl", "quantity": 1, "price": 9.10},
    {"name": "Chips", "quantity": 1, "price": 2.65},
    {"name": "Guacamole", "quantity": 1, "price": 1.85}
  ],
  "paymentType": "Credit Card",
  "currencyCode": "USD"
}

Benefits of structured receipt data:

  • System Integration: The JSON output integrates seamlessly with the expense software, avoiding manual data entry.
  • Process Automation: Employee reimbursements are processed automatically, saving time for both employees and administrators.
  • Data Accuracy: Errors are minimized, as the structured data is machine-processed and verified for consistency (e.g., tax amounts match receipt totals).
  • Insights: The company can analyze spending trends by merchant, category, or department, enabling better budget control.

Converting receipt data into structured formats like JSON helps businesses automate data entry and reduce errors. This process also unlocks valuable insights through data analysis, making tasks like accounting, expense management, and budgeting much easier.

‍

Additional Consideration: Human Readability vs. Machine Readability
JSON provides powerful automation and integration capabilities. Its structure may appear intricate, and business users require accessible, actionable data. A well-designed receipt OCR API with intuitive endpoints will deliver data in a transparent, human-friendly format. This approach ensures teams stay focused on insights and decisions rather than deciphering code.
