Azure Document Intelligence OCR for Receipts does not include card surcharge and returns incorrect total

Azure Document Intelligence OCR for Receipts does not include card surcharge and returns incorrect total. This fails the use-case for our business purposes and may mean we need to switch to a different provider.

In the example below, it returns the subtotal amount ($13.00) as the invoice's amount not the total amount ($13.31). We need a solution for this that doesn't involve manually digging through through the content. I suggest adding additional fields: "gross including transaction fees" and "gross excluding transaction fees".

Feel free to reach out to me directly via email.

Hi Robert,

The current prebuilt Receipt model does not have a CardSurcharge field. Its supported fields include Total, Subtotal, Tax, Tip, and line items. Microsoft defines Total as the full transaction total.

For your example, the expected extraction is:

Subtotal = 13.00
Card Surcharge = 0.31
Total = 13.31

The OCR text clearly contains both Card Surcharge $0.31 and Total $13.31, so returning 13.00 as Total is a model extraction error rather than an intended surcharge limitation.

There is no configuration in the prebuilt Receipt model to add custom fields. For this type of receipt, the practical solution is to use a custom extraction model and define fields such as:

Subtotal
CardSurcharge
Total

Microsoft allows custom models to define your own extraction schema and field types.

If you continue using the prebuilt model, you will need to use the extracted OCR/content to handle Card Surcharge separately and validate that Total is consistent with the amount actually paid.
