You can download any ARTERNAL invoice as an e-invoice. There are two formats:
XRechnung is an XML file. It's made for accounting software, not for reading.
ZUGFeRD is a PDF that looks like your normal invoice, with the e-invoice data built in.
Ask your client or accountant which one they need.
E-invoicing is turned on by request. If you don't see the E-Invoicing section in Settings, contact us and we'll turn it on for you.
Step 1: Add your gallery's details
You only need to do this once, before your first e-invoice.
Go to Settings, then Transactions.
In the E-Invoicing section, fill in your Organization Email, Organization Phone Number, VAT ID, and Tax Number (Steuernummer).
Each field saves when you click out of it.
Step 2: Check the invoice
Open the invoice and make sure it has:
A due date.
A Bill To contact with an email address and a postal address.
At least one work or custom line item.
Your gallery's address on the e-invoice comes from the Point of Sale address on the invoice.
If the due date is missing, you'll see "Invoice due date is required" and the e-invoice won't download. If the Bill To details or the line items are missing, the file still downloads, but your accounting software will reject it.
Step 3: Download the e-invoice
Open the invoice.
Click the ⋮ menu at the top right, next to Download PDF.
Choose E-Invoice (XRechnung) or E-Invoice (ZUGFeRD).
The file is named after the invoice title.
Step 4: Send it to your client
The Send step in ARTERNAL doesn't include the e-invoice file. Attach the file you downloaded to your own email to the client, or upload it to your accounting software.
❓FAQs
Q: Which format should I use?
A: Ask your client or accountant. If they aren't sure, ZUGFeRD is a good choice, because it also opens as a normal PDF.
Q: My accounting software rejected the e-invoice. What should I check?
A: Check that the invoice has a due date, that the Bill To contact has an email address and a postal address, that there's at least one work or line item, and that your E-Invoicing settings are filled in. If it's still rejected, send us the error message.
Q: Why don't I see the E-Invoice options?
A: E-invoicing is turned on for each login separately. Contact us and we'll turn it on for yours.
