    If you still prefer to receive your invoices via Doccle for free, you can cancel your registration in your pre-accounting package and start a new registration in Doccle.

  • This is not absolutely necessary, but is of course always allowed.

  • The Share with Accountant feature in Doccle automatically sends invoices received in the format in which they arrived. The feature can forward all common formats such as pdf, word, excel and even xml and UBL. We send both PDF and UBL to the accountant.

    • Using the company number (CBE) in combination with 0208:

    On Doccle, they remain safely stored for as long as you don’t delete them yourself.

  • A Peppol ID is a unique identification number that identifies organisations within the Peppol network.
    This ID allows businesses to safely send and receive e-invoices.

    Each company has two Peppol IDs:

    • one based on the VAT number
    • one based on the company number

    Useful to share with suppliers who want to send you invoices via Peppol. You can find your Peppol ID within Doccle under “Manage” in your company dashboard. You can copy it instantly using the icon next to it.

  • Peppol stands for “Pan-European Public Procurement Online”. It is a standardized network for exchanging business documents electronically, such as invoices, with trading partners across Europe and beyond.

    The use of Peppol will become mandatory in the future.

  • A Peppol invoice is a structured e-invoice exchanged through the Peppol network.
    It is not a PDF, but a standardized digital file, such as the UBL format.

    UBL (Universal Business Language) is the required format for sending invoices via Peppol.

  • The Peppol network is a standardized and international network used for exchanging electronic documents, such as electronic invoices, which will become mandatory as of 1 January 2026.

  • The Peppol format is a standardized digital file (UBL) that makes e-invoices automatically readable and processable in any accounting software that supports Peppol.

  • If you have any questions about e-invoicing or Peppol, you can visit the Doccle Help Center.
    If you don’t find the answer to your question there, you can contact us directly via this link.

  • The government’s goal is to encourage businesses to digitize their administration. By introducing mandatory e-invoicing, the invoicing process between companies subject to VAT and between companies and the government can be digitized.
    This legislation also provides better visibility on VAT obligations and ensures improved tax monitoring.

  • From 2026, invoices between businesses and the government must be sent electronically. The Peppol network (Pan European Public Procurement OnLine) has been chosen as the channel for electronic invoicing.
    By standardizing the e-invoicing format, invoices can be automatically processed by any accounting software.
