Kaution (security deposit)

A Kaution in the German-speaking hospitality context is a sum the operator holds as security: against damage to the pitch or accommodation, failure to return hired equipment, or to guarantee a running account. It is not the same as an Anzahlung (a booking deposit that confirms a reservation and is later applied against the final invoice) or a Vorauszahlung, full prepayment. A Kaution is held in trust and returned, in full or in part, after check-out once the operator confirms nothing is missing or broken. In Germany the rules for holding and returning Kautionen are governed by the BGB, in Switzerland by the Code of Obligations; operators must hold them separately from income to comply. For campgrounds, Kautionen appear in several distinct situations. Annual and seasonal pitch contracts (Dauermieter-Verträge) commonly require a Kaution to cover end-of-season pitch restoration. Equipment hire (bikes, e-bikes, SUPs, kayaks) calls for a Kaution held against the return of each item and released, or partly kept, when the kit comes back. Barrier and access-card schemes sometimes hold a Kaution against the card itself. Managing these manually (tracking what each guest owes, releasing on departure, keeping held amounts off earned income) is error-prone and creates audit risk. Software that holds a Kaution against a hire or a contract, records the release event, and posts only the retained portion to the folio keeps the process auditable and removes the temptation to treat a security deposit as revenue before it has been earned.
