The need

A holiday rental or small estate receives bookings from several platforms, sells direct on its own website, offers extras and bookable resources. It then has to prepare the accommodations, invoice, collect payment, send reminders and declare the tourist tax. These tasks usually live in several tools that do not share their data. GuestFlow brings them together around one calendar and one customer file.

The solution

  1. 01

    Calendar sync with Airbnb, Booking, Abritel, Gîtes de France and other platforms, and stays published to Google Calendar.

  2. 02

    Complete pricing engine: seasons, and pricing recipes that follow the school holidays and detect long weekends. Rates carry over from one year to the next without being entered again.

  3. 03

    Booking flow built into the estate's website: availability calendar, extras, price computed live, online payment through Qonto and cancellation insurance offered to the guest.

  4. 04

    Every extra offered to guests is managed in GuestFlow: a dedicated connector publishes them automatically on the website.

  5. 05

    Resource booking by time slot, such as the Nordic bath, also open to visitors from outside the estate.

  6. 06

    Arrival airlock: it gives guests everything they need at check-in and flags any extras they have not paid yet. Departure airlock: no check-out step is forgotten, and extras or services taken during the stay are settled before leaving.

  7. 07

    Daily schedule, plus cleaning and preparation schedules for the accommodations between stays.

  8. 08

    CRM: customer records and addresses, stay history, quotes, invoices, deposits and balances.

  9. 09

    Simpler paperwork: a dedicated access for the accountant, an export in the accountant's format and a page for the tourist tax declaration.

  10. 10

    Automated emails timed to the stay: confirmation, preparation at D-7, arrival details, thank-you, payment reminders.

  11. 11

    Android and iOS apps, with a notification for each new booking and before each imminent arrival.

  12. 12

    Connected to the estate's home automation, run by Sowel: guests open the gate from an app on their phone, control the devices in their accommodation remotely for their comfort, and follow their electricity use and the solar power available, so they can consume more responsibly.

The outcome

In production at Domaine Solio, where GuestFlow manages the bookings of both accommodations and the Nordic bath, from first contact to invoice. In preparation: an app for guests to order services and book activities from their smartphone, with invoicing handled directly by GuestFlow.
