    "Structured data vs. PDF – why does it matter?"

    "A PDF invoice is a human-readable image. A structured invoice (e.g., Finvoice, Peppol BIS) is machine-readable data. The difference is significant from an regnskab perspective:"

    EN 16931 – purpose of the standard

    EN 16931 is a European standard that defines the minimum data content of an e-invoice. It was created based on EU Directive 2014/55/EU and is mandatory for public sector invoicing.

    The standard defines, among other things:

    • Mandatory data fields (seller, buyer, invoice total, VAT breakdown)
    • Structure of invoice lines
    • VAT categories and codes
    • Presentation of payment terms
    • Handling of attachments

    Benefits in regnskab

    When invoice data is in a structured format, regnskab benefits significantly:

    • Automatic allocation: the system can assign the invoice line to the correct regnskab account
    • VAT calculation becomes automated: VAT codes are transferred directly from the invoice data
    • Reconciliation is faster: payments are automatically allocated to invoices
    • Reporting improves: reports can be generated directly from structured data
    • Reduction of errors: no manual data entry

    Preparation in a small business

    1. Ensure that your faktureringsprogram produces EN 16931-compliant e-invoices
    2. Implement financial management software that can receive and account for structured invoices (e.g. Eemel Accounting)
    3. Request e-invoices from your suppliers instead of PDF invoices
    4. Activate automatic regnskab and VAT rules
    5. Utilize structured data in reporting

    Practical example: a construction company and purchase invoice processing

    A small construction company previously received indkøbsfakturaer as PDFs via email. The accountant manually entered each invoice into the regnskab system. Typically, the processing time was 5–10 minutes per invoice.

    Transition to receiving structured e-invoices with Eemel Accounting:

    • Indkøbsfakturaer modtages direkte i softwaren som strukturerede data
    • Automatic allocation assigns the invoice to the correct account
    • Processing time dropped from 5 minutes to less than 1 minute per invoice
    • Monthly invoice processing was sped up by approximately 4 hours in total

    Try it in practice

    Eemel Accounting automatically receives and accounts for structured e-invoices. Regnskab is handled more efficiently.
