Rentability
Rentability defines when an accommodation or add-on can and cannot be booked. It is based on parameters that reflect your business logic.
A rentability rule groups multiple conditions that define booking restrictions, such as minimum stay, allowed arrival days, or specific booking periods. Rentability rules can be created in the representation of an accommodation type.
A rentability set is a collection of rentability rules. You apply a set to an accommodation type to manage rules efficiently. Rentability sets can be created in Revenue Manager.
By combining rules and sets, you can optimise occupancy and adapt to changing demand.
Example: For Easter, you might not want a changeover on Easter Monday. You can create a rentability rule that prevents arrivals and departures that day, ensuring guests arrive or leave on Tuesday instead.

Rentability rules
A rentability rule determines whether a booking can be made. You can configure a rule using the following parameters:
- Stay dates – the date range when the guest stays at a location
- Book dates – the date range when the reservation is created
- Length of stay – the minimum and/or maximum number of nights
- Arrival and departure days – the days guests can arrive or leave (for example, Mondays only)

Rentability sets
When you manage more than one rule, group them into a rentability set. You can apply a set to multiple rules to several accommodation types at once, saving time and reducing errors.
You can create rentability sets:
- One by one – configure rules directly in Revenue Manager.
- In bulk – use the batch update template to create or copy rules across locations.
- Import - use the import functionality to create the rentability rules for your set and link them to the applicable representations.

Additional parameters
In addition to the standard parameters in rentability rules, two extra parameters let you fine-tune occupancy and respond to changing demand.
Deviation
The number of days before arrival when a booking is still allowed. You use this to relax conditions for last-minute bookings, for example, by reducing the minimum stay or allowing different arrival days.
Pushing last-minute sales to make sure the planning chart is fully booked is a common goal. When rentability conditions are strict, you can use deviation to make them more flexible for arrivals close to the booking date.
With max deviation, you can:
- Allow shorter stays than your standard minimum stay.
- Allow additional arrival or departure days.
- Loosen conditions that would normally block a last-minute booking.
Note
There is a limit to how many rentability rules can overlap in a single stay period when using deviation. If you cannot add a new rule, review existing overlapping rules first.
Gap
The minimum number of days required between bookings to maximise your occupancy.
The gap parameter helps you avoid unbookable nights in the planning chart. If you set a minimum length of stay, the gap functionality ensures that no booking is accepted if it would leave fewer nights available than your minimum stay.
For example, if your minimum stay is 4 nights and a unit is already booked from 1–5 September, a request for 31 August–3 September would be rejected because it would create a 1-night gap that cannot be sold. You can apply gap settings either to an individual rentability rule or in bulk when creating new rules.
Remember:
- Gaps are optional. Not every rentability rule needs one.
- Both arrival and departure dates must respect the gap rule.
