Your books have to survive ten years, and prove nobody touched them.

The GeBüV (Geschäftsbücherverordnung) is the Swiss ordinance that spells out how the books and records required by the Code of Obligations must be kept and retained. In plain terms it asks four things. Records must be retained for ten years. They must have integrity: kept so that any later change is detectable, so a figure cannot be quietly rewritten after the fact. They must be orderly: documented and organised so a third party can find their way through them. And they must be available: producible in readable form for an inspection within a reasonable time.

Those duties fall on you as the operator and on your Treuhänder who keeps the books. No software vendor can discharge them for you, and none can certify that your bookkeeping meets them: that judgement is your accountant’s and, ultimately, an auditor’s.

What software can do is stop being the weak link. If your booking, billing and payment records live in a system where anyone can edit history, where retention depends on somebody remembering, and where an audit means a week of exporting spreadsheets by hand, the GeBüV becomes a lot harder to satisfy than it needs to be.

Orderliness is easier to demonstrate when the numbers already agree. Every invoice Grondia issues is a compliant Swiss QR-Bill carrying a structured QR-IBAN reference. That reference is what makes the invoice pay itself in: when the guest settles it, the money lands already matched to the right folio, so there is no line-by-line reconciliation and no mystery deposit at month end.

The same holds across the stay. Pitch, tourist tax, shop, bar and rentals all accumulate on one running folio and settle once at check-out, as one record rather than a scatter of loose transactions. When your accountant opens the export, the payments, the tax lines, the deposits and the refunds are already tied to the bookings they belong to.

That is the difference between records that are technically retained and records that are actually auditable.

Be wary of any campsite-software vendor that sells you "GeBüV-compliant" as a checkbox. GeBüV compliance is not a property a piece of software can hand you. It is a property of how your whole bookkeeping is kept, and the responsibility for it stays with you and your Treuhänder.

What we will do is tell you precisely which mechanics exist (the change log that cannot be edited, retention as long as the law requires, the Swiss hosting, the audit-ready export), so that you and your accountant can judge them against your obligations. That is the substance behind the principles.

What we will not do is print a certificate we are not in a position to issue. If a competitor’s page claims one for you, treat it with the same curiosity you would treat any other too-good-to-be-true line.
