With Subscript, you can send your German customers e-invoices in the ZUGFeRD format: a normal PDF/A invoice, with embedded invoice data for machine-readable flows, inside it.

What you will need:

Turning on eRechnung:

  1. Go to Settings > Subscript Billing > Invoice Settings and find the sender organization you use to invoice German customers from, and click on Edit:

  1. Switch on eRechnung for this organization by clicking Send eRechnung (ZUGFeRD) invoices from this entity, the eRechnung section. Then, the seller details will become editable, and you will be able to fill them:

It's important that your Declared VAT rate matches what you use when sending the invoices to your German customers!

  1. After you finish filling out the required fields above, click Save and eRechnung will be enabled for the invoices and credit notes from this entity to customers with billing address within Germany.

Optional: Choose per customer schedule

By default, Subscript will, when using a sending organization with eRechnung enabled, whether it's necessary to have it attached to the PDF or just send the regular way, as it was before. However, you can also override by hand, when necessary, this configuration individually per invoicing schedule in its settings:
