Do I need software to open e-invoices?

For XRechnung, yes, because it contains data only. The free plan shows it readably. ZUGFeRD invoices also contain a PDF.

Can I leave e-invoices in my mailbox?

Usually not. The invoice must be kept unchanged and findable for eight years. The free plan archives every invoice in its original form.

What happens with a faulty e-invoice?

The check shows which rule of EN 16931 is broken. You can query the invoice with the sender and ask for a corrected version.

E-invoicing guide

Receive e-invoices for free

Since 1 January 2025 every business in Germany must be able to receive e-invoices, including those that do not have to issue them yet. The plan “E-invoice receiving” covers this duty at no cost: receive, read, check and archive.

Start for free

What receiving requires

The e-invoice must arrive in its original format, be made readable and be kept unchanged. A mailbox is enough for delivery. On top of that you need software that shows the XML file and an archive for eight years (§ 14b UStG, § 147 AO).

What the free plan does

Receive e-invoices by upload or through a mailbox of its own.
Show XRechnung and ZUGFeRD invoices readably, with every line item and amount.
Check every e-invoice against EN 16931 and name any error.
Archive the original, for eight years.

Who the plan is for

For small businesses that do not have to issue e-invoices under § 34a UStDV but must be able to receive them. And for everyone who moves to issuing later and wants receiving settled today.

You do not write your own e-invoices with the free plan; that is what TWT Invoice is for. When you switch, the invoices you received and the archive stay where they are.
