Guides
What the EU actually requires, and when
Thirty-two guides on the mandates, the formats, the Peppol network and the VAT that decides whether an invoice is accepted. No sign-up, and each one says where Zeppol does not help.
Guides marked DE are written in German.
Germany and the 2027 mandate
Who it reaches, when, and the duty that already applies to you today.
Formats and the standard
EN 16931 and the three things people mean when they say e-invoice.
The Peppol network
What it is, how a store joins it, and how a buyer is addressed on it.
VAT on Shopify
The half of e-invoicing that decides whether the document is refused.
Country by country
Every EU mandate, its date, and whether Peppol is a route into it at all.
Compared with the alternatives
Where another app is the better answer, said plainly.
Zeppol turns this into something you do not have to read
Every B2B order becomes an EN 16931 document, checked against these rules before it leaves. Leave your email and I will tell you when it is installable.
