What exactly is The Big One?

Operations software for short-term rentals: cleaning schedule, cleaner assignment, field app with checklist and photos, linen and rounds, invoicing. It replaces the spreadsheet, messaging apps and follow-up phone calls.

Who is this cleaning management software for?

Cleaning companies, rental management companies, owners of several holiday lets, hotels, aparthotels and tourist residences, corporate housing for mid-term stays, and student or coliving residences.

Do my Airbnb and Booking reservations come in automatically?

Yes, through your property management system (PMS) or your channel manager. The Big One connects to more than 40 systems, including Guesty, Hostaway, Hospitable, Apaleo and Lodgify: each check-out creates its cleaning automatically.

Do my cleaners need to install an app?

No. The Big One opens in the browser of any phone, iPhone or Android, in each cleaner's language. There they find their day, the address, the access code, the property's checklist and the photos to take. Photos upload even on a weak network: they are sent as soon as the connection returns. The iPhone and Android apps are coming to the App Store and Google Play.

Can I prove the work done to my clients or owners?

Each job carries its photos, its times and its checklist. The report is shared with a simple link, with your logo and your colours, like your PDFs. Your clients can also have their own space: for each one, you choose the properties and what they see (schedule, photos and reports, assigned staff, reservations, documents, reports and invoices).

Where is my data hosted, and can I get it back?

In the European Union, in Ireland. Everyone sees only what their role allows, and your company's administrator can download an archive of all your data whenever they like. The details are on the “Security and data” page.

How much does The Big One cost?

The price depends on the number of active properties and the number of visits. A property is active in a month when it has at least one reservation or one job: a chalet closed all summer does not count in those months. A visit is one property serviced in the day, whatever the services. Leave your details in the form at the bottom of the page: we will get back to you with an offer suited to your properties.
