If you create or send invoices in Accountable, you'll sooner or later come across terms like XRechnung, ZUGFeRD or PEPPOL.

πŸ‘‰ Important to know:

  • XRechnung and ZUGFeRD are formats for e-invoices

  • PEPPOL is a network for sending these invoices


Background: Why do e-invoices exist?

E-invoices are structured, machine-readable invoices that can be processed automatically. This saves you time, reduces errors, and makes accounting significantly more efficient.

Benefits include:

  • Fewer errors

  • Faster processing

  • Simpler accounting

Legal requirements – when do e-invoices become mandatory?

The following deadlines apply in Germany:

  • From 1 January 2025: All businesses must be able to receive e-invoices.

  • From 1 January 2027: Businesses with a previous year's turnover above €800,000 must also send e-invoices.

  • Until 31 December 2027: Businesses with turnover below €800,000 may still send paper or PDF invoices (with the recipient's consent).

  • From 1 January 2028: All businesses in the B2B sector must send e-invoices – without exception.


ZUGFeRD in Accountable

ZUGFeRD combines a regular PDF (human-readable) with embedded XML data (machine-readable). In Accountable, you can choose to export your invoice as a ZUGFeRD PDF when creating it – making it directly processable for your customers.

Benefits

  • As easy to read as a regular PDF

  • Machine-readable

  • Ideal for B2B invoices

πŸ’‘ Tip: When you create and send an invoice in Accountable, an e-invoice in ZUGFeRD format is automatically attached. You don't need to do anything extra, just create your invoices as usual and all e-invoice requirements are taken care of.


XRechnung in Accountable

XRechnung is an XML format that public authorities in Germany are required to use. In Accountable, you can create XRechnungen directly and export them as XML or send them straight away.


PEPPOL in Accountable

PEPPOL is not an invoice format – it's a transmission network. In Accountable, you can send invoices directly via PEPPOL, whether XRechnung or ZUGFeRD – and it works across Europe.

Important: For PEPPOL delivery to work, your recipient also needs to be registered in the PEPPOL network. This is already the case for many public authorities and larger companies, but not all. If in doubt, check with your customer beforehand.

Benefits

  • Secure delivery to authorities and businesses

  • Automatic data transfer into your customer's accounting system

  • Particularly useful for international invoices

Frequently asked questions

Can I send XRechnungen as a PDF?

No. An XRechnung is a pure XML file. However, Accountable always automatically creates and attaches a PDF alongside it.

Does PEPPOL belong to XRechnung or ZUGFeRD?

No. PEPPOL is a network for transmission. You can send both XRechnungen and ZUGFeRD invoices via PEPPOL.

Do I need PEPPOL?

As long as you simply want to create and send e-invoices, you don't need to register for PEPPOL. However, PEPPOL is useful when your recipient is also in the network, this is something you should clarify in advance.

They always answer right away to any question I have, they provide clear answers, and they are very patient even when I struggle to understand. They try to explain in different ways. They are very helpful, responsive and friendly.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful. Combined with the AI I never feel alone with Accountable.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
