The Document Intelligence receipt model combines powerful Optical Character Recognition (OCR) capabilities with deep learning models to analyze and extract key information from sales receipts. Receipts can be of various formats and quality including printed and handwritten receipts. The API extracts key information such as merchant name, merchant phone number, transaction date, tax, and transaction total and returns structured JSON data.

Supported receipt types:

  • Thermal
  • Credit Card
  • Gas
  • Parking
  • Hotel
  • Transportation
  • Communication
  • Entertainment
  • Flight
  • Training
  • Pharmacy/Medical

Receipt data extraction

Receipt digitization encompasses the transformation of various types of receipts, including scanned, photographed, and printed copies, into a digital format for streamlined downstream processing. Examples include expense management, consumer behavior analysis, tax automation, etc. Using Document Intelligence with OCR (Optical Character Recognition) technology can extract and interpret data from these diverse receipt formats. Document Intelligence processing simplifies the conversion process but also significantly reduces the time and effort required, thus facilitating efficient data management, and retrieval.

Receipt model data extraction

See how Document Intelligence extracts data, including time and date of transactions, merchant information, and amount totals from receipts. You need the following resources:

  • An Azure subscription—you can create one for free.

  • A Document Intelligence instance in the Azure portal. You can use the free pricing tier (F0) to try the service. After your resource deploys, select Go to resource to get your key and endpoint.

Screenshot of keys and endpoint location in the Azure portal.

Note

Document Intelligence Studio is available with v3.1 and v3.0 APIs and later versions.

  1. On the Document Intelligence Studio home page, select Receipts.

  2. You can analyze the sample receipt or upload your own files.

  3. Select the Run analysis button and, if necessary, configure the Analyze options:

    Screenshot of Run analysis and Analyze options buttons in the Document Intelligence Studio.

    Try Document Intelligence Studio.

Document Intelligence Sample Labeling tool

  1. Navigate to the Document Intelligence Sample Tool.

  2. On the sample tool home page, select the Use prebuilt model to get data tile.

  3. Select the Form Type to analyze from the dropdown menu.

  4. Choose a URL for the file you would like to analyze from the below options:

  5. In the Source field, select URL from the dropdown menu, paste the selected URL, and select the Fetch button.

    Screenshot of source location dropdown menu.

  6. In the Document Intelligence service endpoint field, paste the endpoint that you obtained with your Document Intelligence subscription.

  7. In the key field, paste the key you obtained from your Document Intelligence resource.

    Screenshot of the select-form-type dropdown menu.

  8. Select Run analysis. The Document Intelligence Sample Labeling tool calls the Analyze Prebuilt API and analyze the document.

  9. View the results - see the key-value pairs extracted, line items, highlighted text extracted, and tables detected.

Note

The Sample Labeling tool does not support the BMP file format. This is a limitation of the tool not the Document Intelligence Service.
