DigitAIuserAccounting operatorAdministrator

This article details the best practices and technical requirements for sending vouchers via email to DigitAI, ensuring successful and error-free ingestion. Learn how to avoid common issues related to formats, resolution, and email structure.

Step by step

  1. 1

    Supported File Formats

    To ensure the correct ingestion of your vouchers into DigitAI, only the following file formats are accepted as attachments: * **PDF**: Text/vectorial PDF is recommended for better quality and processing. Scanned PDFs are also accepted, provided they meet the minimum resolution. * **TIFF**: TIFF image files.

  2. 2

    Document Resolution and Quality

    The quality of the documents is crucial for their processing. * **Resolution**: A minimum resolution of 300 DPI (dots per inch) is recommended for scanned documents. This ensures readability and correct data extraction.

  3. 3

    Email Structure

    The way your email is structured directly impacts ingestion. * **Attachments**: Vouchers must always be sent as file attachments. Avoid pasting images directly into the email body, as they will not be processed. * **Multiple Files**: You can attach multiple vouchers in a single email. Each file will be processed individually. * **Signatures with Images**: Email signatures containing images (logos, icons) are generally ignored by the ingestion system, but it's good practice to ensure they do not interfere with the main attachments.

  4. 4

    Troubleshooting: What to do if a voucher is not processed?

    If you have sent an email with vouchers and do not see them processed in your DigitAI inbox, follow these steps: * **Check format and resolution**: Ensure your files meet the format (PDF, TIFF) and resolution (300 DPI) requirements. * **Review email structure**: Confirm that the documents were sent as attachments and not pasted into the email body. * **Contact support**: If problems persist, contact the DigitAI support team.
