Residence Manager
Read full descriptionHide full description
Residence Manager is the Austrian-built app for organizing shared vacation properties. Whether family-owned, shared among friends, a co-ownership or a community of heirs: when several people use one vacation property, you need clear bookings, transparent costs, reliable processes and simple communication. Residence Manager helps owners organize stays, guests, expense contributions, cleaning and services in one place — without Excel chaos, WhatsApp coordination or unclear responsibilities. WHO IS RESIDENCE MANAGER FOR? Residence Manager is made for: • families with a shared holiday home • communities of heirs with a vacation property • co-ownership communities • groups of friends sharing a property • private vacation properties with optional external bookability • owners who want to coordinate cleaning and services digitally WHAT RESIDENCE MANAGER DOES • manage bookings and stays centrally • prevent double bookings • organize family members, friends and guests • flexibly control private and public use • enable external bookings when the property is published • map expense contributions transparently • track payments and costs clearly • coordinate cleaning and service providers • trigger cleaning tasks automatically after stays • onboard service partners by invitation • synchronize external calendars • structure owner rights and roles clearly • rate guests internally PRIVATE USE OR EXTERNAL BOOKINGS Owners decide how their property is used. A vacation property can be used exclusively privately by family, friends or co-owners. If owners make the property publicly available, external guests can request and book it too. The decision always stays with the owners: they determine whether the property is visible, which bookings are accepted and who gets access. CLEANING PORTAL AND SERVICE PROVIDERS Residence Manager also supports owners in organizing cleaning, property care and service partners. Service providers can be invited and assigned to specific properties or tasks. After a stay, cleaning tasks can be created automatically. Providers only see the information necessary for their job. FULL CONTROL FOR OWNERS Residence Manager is not a classic booking platform. The focus is on organization, transparency and owner control. Owners decide about visibility, bookings, access, service providers and costs. SYNC CALENDARS Bookings from external calendars can be synchronized with Residence Manager. Owners keep an overview of availability and avoid double occupancy. New bookings in Residence Manager can block external calendars so availability stays current. RATE GUESTS INTERNALLY Private properties need trust. That is why owners can rate guests internally. These ratings protect the property and help other owners with future decisions. Guests do not rate owners publicly. TRANSPARENT EXPENSE CONTRIBUTIONS Owners can define whether certain stays carry an expense contribution. Costs stay traceable, and personal conversations about money are avoided. LESS COORDINATION. MORE CLARITY. Residence Manager brings structure to the shared use of private vacation properties — from bookings and costs to cleaning. So the holiday home stays what it should be: a place for family, rest and good times together. TRY IT FREE FOR 14 DAYS Start without obligation and test Residence Manager free for 14 days. Residence Manager — own together, organize simply.
