    ## Urbario
    
    Urbario is software for service charge statements for residential and commercial property. It brings master data, receipts and advance payments together in one place, allocates costs according to stored allocation keys and produces a finished statement.

    ## Authiane
    
    A SaaS product needs user accounts, sessions, API keys, subscriptions, invoices and usage limits. These functions are almost the same in every product, and they still have to be built, tested and maintained each time. Authiane provides them as one platform that you run in your own infrastructure, so this work is done once.

    ## Handtuch Held
    
    No 6 a.m. sprint required: Handtuch Held ends the towel race at the hotel pool. Loungers are assigned fairly and calmly – steered by the hotel, relaxed for guests.
    
    ### At a glance
    
    -   One guest, one lounger.
    -   Pools, areas and rules remain firmly in the hotel's hands – the operation decides, not the early birds.
