What is e-invoicing?

E-invoicing lets business customers receive invoices through a supported e-invoice network. This can make invoice handling easier and more automated, especially for companies that use accounting systems.

E-invoicing is set up per domain and applies only to future invoices.

Note: PDF invoices will still be generated and available in the Control Panel, even if you use e-invoicing.

Who can use e-invoicing?

• Available for organisations with a registered VAT number.
• Customer needs to be in an EU country.

You enable e-invoicing per domain, which means you can choose which domains should use e-invoicing and which should not.

Where do I manage e-invoicing?

You manage e-invoicing in the one.com Control Panel.

1. Log in to the one.com Control Panel.
2. Go to Invoices, under My Account.
3. Find the domain you want to manage.
4. Click Activate in the E-invoice column, or open E-invoice settings for that domain.

How do I activate e-invoicing?

To activate e-invoicing for a domain:

1. Open E-invoice settings for the domain.
2. Set the status to Active.
3. Choose your e-invoice operator (for example: Peppol BIS or xRechnung).
4. Enter your E-invoice ID.
5. Click Save.

After saving, you’ll see a confirmation message that e-invoicing is now active for the domain. All future invoices for this domain will be delivered by e-invoicing.

What do the e-invoice statuses mean?

In the invoice overview, you’ll see different e-invoice statuses for each invoice:

• Activate – e-invoicing is not set up yet for this domain.
• Processing – the invoice is being delivered.
• Delivered – the invoice was successfully delivered.
• Failed – delivery failed, and action is needed.
• Not sent – the invoice was not sent.
• Unsupported – e-invoicing is not supported for this invoice or domain.

What happens if an e-invoice fails?

If an e-invoice cannot be delivered, you’ll see a warning message in the Control Panel.

To fix this:

1. Open E-invoice settings for the affected domain.
2. Check or update the operator and E-invoice ID.
3. Click Save.

Any failed deliveries will be automatically retried once your details are updated.

How do I update or deactivate e-invoicing?

You can update your e-invoice details at any time.

1. Go to E-invoice settings for the domain.
2. Update the operator or E-invoice ID.
3. Click Save.

Changes apply to future invoices only.

If you no longer want to use e-invoicing for a domain:

1. Open E-invoice settings.
2. Set the status to Inactive.
3. Click Save.

Future invoices for the domain will then be sent by email as PDF files, as usual.
