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.
