EN 16931 is an EU standard for the structured data of e-invoices. It defines what information an electronic invoice must contain. Neste artigo, abordamos what the standard means from an contabilidade perspective and how a small business benefits from structured data.
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 for contabilidade:
| Ominaisuus | PDF-lasku | Rakenteinen lasku |
|---|---|---|
| Tiliöinti | Manuaalinen tai OCR (virhealtis) | Automaattinen sääntöjen perusteella |
| ALV-käsittely | Tarkistettava käsin | ALV-koodit mukana datassa |
| Arkistointi | Erillinen tallennus | Integroituu suoraan kirjanpitoon |
| Hakeminen | Hankala | Helppo (hakukentät) |
| Virheet | Yleisiä (näppäilyvirheet) | Harvinaisia (data siirtyy suoraan) |
The purpose of the EN 16931 standard
EN 16931 is a European standard that defines the minimum content of an e-invoice. It was developed 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 amount, VAT breakdown)
- Structure of invoice lines
- VAT categories and codes
- Presentation of payment terms
- Handling of attachments

Benefits in contabilidade
When invoice data is in a structured format, contabilidade benefits significantly:
- Automatic contabilidade entry: the system knows how to allocate the invoice line to the correct contabilidade account
- VAT calculation automates: VAT codes are transferred directly from invoice data
- Reconciliation speeds up: payments are automatically allocated to invoices
- Reporting improves: reports can be generated directly from structured data
- Reduction of errors: no manual keying
Preparation in a small business
- Ensure that your software de faturação produces EN 16931 compliant e-invoices
- Implement an financial management software that can receive and account for structured invoices (e.g., Eemel Accounting)
- Request e-invoices from your suppliers instead of PDF invoices
- Activate automatic contabilidade and VAT rules
- Utilize structured data in reporting

Practical example: construction company and purchase invoice processing
A small construction company previously received faturas de compra as PDFs via email. The accountant manually keyed every invoice into the contabilidade system. Typically, processing time was 5–10 minutes per invoice.
Transition to receiving structured e-invoices with Eemel Accounting:
- As faturas de compra chegam diretamente ao software como dados estruturados
- Automatic contabilidade allocates the invoice to the correct account
- Processing time dropped from 5 minutes to less than 1 minute per invoice
- Monthly invoice processing sped up by approximately 4 hours in total
Try it in practice
Eemel Accounting automatically receives and accounts for structured e-invoices. Contabilidade becomes more efficient.
