Grondia
Accounting & DATEV export

Books that close themselves

Every payment your campsite takes arrives already carrying its tax line and already matched to the right booking. At month end there is one export for your Treuhänder — not an evening of re-keying receipts into a second system.

Every franc lands already booked

Every invoice Grondia issues is a compliant Swiss QR-Bill with a structured QR-IBAN reference. When the guest settles it, the money lands already matched to the right folio — there is no line-by-line reconciliation and no mystery deposit at month end.

Online payments at booking run through TWINT, Visa, Mastercard and PostFinance; LSV direct debit and bank transfer are there for the guests who prefer them. Whichever way the money comes in, it posts against the booking it belongs to.

The export your Treuhänder actually asks for

One export gives your accountant a DATEV-friendly, VAT-aware, audit-ready file. Every payment, every tax line, every deposit and every refund is in it, already coded — so nobody is typing numbers from a PDF into accounting software a second time.

Because every line already carries its own tax rate, your Treuhänder reviews and posts; they do not rebuild your month from scratch.

One folio, not three systems

Pitch fees, visitor tax, shop, bar and rentals all post to one running guest folio and settle once at check-out. The figures your reception sees are the same figures that export.

That means you are not reconciling a POS till against a booking system against a spreadsheet. There is one source of truth, and the accounting export is drawn straight from it.

Deposits and refunds where they belong

A deposit is not revenue yet, and a refund is not a new sale. Grondia keeps deposits, full pre-payments and refunds as their own lines, each tied to its booking, so they land in the right place in the export instead of quietly distorting your turnover.

And because there is no per-booking commission, the amount the guest paid is the amount you account for — no third-party cut to back out first.

Audit-ready, and honest about the label

Every payment and every change is written to a tamper-evident audit log, and records are kept for the retention period the law requires. The export is structured so your accountant can meet GoBD-style requirements — we explain how it maps, we do not sell you a certificate.

For sites in Germany, TSE fiscalisation is built into the POS module, so till receipts are signed as the German rules require.

Frequently asked questions

Does Grondia export to DATEV?
It produces a DATEV-friendly, VAT-aware, audit-ready export containing every payment, tax line, deposit and refund, ready for your Treuhänder to review and post. It is built to drop into a DATEV workflow rather than being re-keyed by hand.
Do I still have to reconcile guest payments by hand?
No. Every invoice is a Swiss QR-Bill with a structured QR-IBAN reference, so when a guest pays, the money arrives already matched to the right folio — there is no line-by-line reconciliation at month end.
Is Grondia GoBD certified?
No. GoBD is a set of principles, not a product badge. Grondia keeps a tamper-evident audit log and enforced retention and structures the export to fit GoBD-style requirements — we explain how it maps rather than claiming a certificate.
How are VAT, deposits and refunds handled in the export?
Every line in the export carries its own tax rate. Deposits, full pre-payments and refunds stay as their own lines tied to the booking, so they land correctly in the export instead of distorting turnover.
What about German TSE fiscalisation?
For sites in Germany, TSE fiscalisation is built into the POS module, so shop, restaurant and activity receipts are signed as the German rules require. It works alongside the same accounting export.
