Mandatory B2B e-invoicing rolls out across EU countries through 2026 — Poland (KSeF), Germany, France, Belgium, Spain. Equestrian stables are not an exception — if you issue invoices (and you do: passes, boarding, lessons), you’ll have to issue them through the structured platform.
What changes
Until now you could issue an invoice in Word, send a PDF by email and book it. From 2026 — not. Every invoice must:
- Be issued in a structured format (XML, country-specific schema)
- Be sent directly to the national platform through the government network
- Get a unique platform ID
- Be delivered to the client through the platform (not just email)
Penalty for non-compliance varies by country but typically reaches 100% of the invoice VAT, plus the buyer can’t deduct VAT.
What it means for your stable
- Excel + Word stops working as an invoicing solution
- The client doesn’t get a PDF in their inbox — they get the invoice in their platform panel
- Corrections (e.g. pass refund) go through the platform
- Bookkeeping export changes — from “send PDFs by email” to “share via platform”
What you can do now
- Check which system you issue invoices from — does it have the e-invoicing certification (or compatible)?
- If you use Excel / Word — you have months to switch. Don’t leave it to the last minute.
- Inform your accountant — they also need a compatible system.
- B2B clients (companies) — let them know that from the deadline they’ll receive invoices through the platform, not email.
Can I test e-invoicing before it’s mandatory?
Yes. Most national platforms offer a test environment. For Polish KSeF, Hovera lets you pick the environment (test, demo or production) in the KSeF settings, upload your stable’s certificate and check the login with the “Check KSeF connection” button. Hovera sends invoices to Polish KSeF 2.0 only; other countries’ platforms are not supported.
