Where does the data displayed in the processing of documents and transactions come from?

When a document is uploaded, Candis tries to fill in its fields automatically. You can recognize this by the green or orange dot next to the value.

Various sources are used for reading, these can be seen in the tooltip.

For example, the invoice number of this document was read from the document. Other fields, such as the IBAN, can be stored at the business partner if this was not found on the invoice.

The following data sources are used for reading fields:

  1. Document

  2. Transaction

  3. Credit card

  4. Contact

  5. Cost center/cost object

  6. Field suggestions


Data source: Document

In this case, the suggested data was read from the document itself. This can happen in different ways:

  • Optical Character Recognition (OCR):

    The process involves capturing letters, words and numbers in image files, such as scanned documents, and converting them into text. In some cases, recognition can be subject to errors. Example: Whether a character is an “O” or a “0” (zero) can only be recognized by the context.

    The certainty (confidence) of a value is shown in orange and green:

    • Orange: The field is classified as unsafe. These fields should always be checked.

    • Green: The field is classified as safe. These fields can be skipped.

    Fields change from orange to green over time. If documents from a supplier are often read out and not corrected by you, they will be displayed in green in future, even though the data source is the document.

  • Candis Template:

    If the text recognition is inaccurate for certain documents, Candis Support can create a so-called template for certain incoming invoices/suppliers. How can OCR recognition be improved?

  • E-invoices:

    An electronic invoice, or e-invoice for short, is a machine-readable document that provides its data in a structured form. The data does not have to be laboriously read by a text recognition system, but is always correctly available.

    Candis supports the two currently common types of e-invoices: ZUGFeRD and X-Rechnung.


Data source: Transaction

If invoices are linked to transactions, the transaction data is displayed in the fields instead of the invoice data.

Candis only exports transaction data with document image and therefore certain invoice data cannot be recorded or transaction data cannot be changed.

Data that is used from the transaction is:

  • Document type

  • Invoice date

  • Delivery date

  • Due date

  • Invoice correction

  • Total amount

  • Currency


Data source: Credit card

The credit card data source is displayed if booking rules have been added to the credit card.


Data source: Contact

The following fields can be proposed via the business partner:

  • Create bank transfer

  • Payment term (cash discount date, cash discount rate and cash discount amount)

  • Due date

Candis uses the following data to recognize the business partner of a document itself:

  1. Company name

  2. VAT ID

  3. Tax number

  4. IBAN

If the recognition of the contact is incorrect, please message an “administrator” or “accountant” so that they can check the data assigned to the contact. It is often the case, for example, that the company's own IBAN, tax number or VAT ID have been stored for the business partner.


Data source: Cost center/cost object

If the cost center or cost object is read from a document, the corresponding approver is also added automatically.

The prerequisite is that an approver has been assigned to the corresponding cost center or cost object. You can also add several people. These are all added to the 1st approval step. This means that only one of these persons has to approve.

If this is not (or no longer) correct, please contact the responsible team member with the Administrator role. Only the administrator can change the settings and add/remove a new user.


Data source: Field suggestion

The data from this field has been suggested based on past entries. There are field suggestions for the following fields:

  • General ledger account

  • Tax code

  • Cost center

  • Cost object

  • Approval (workflow; approver)

If a cost center has been assigned to a supplier's invoice for the first time, Candis will suggest the same cost center for the next invoice from the same supplier. For suppliers with more than 20 processed invoices, only the most recent 20 will be used as a basis for the suggestions.
