Booking rules: Availability

Updated on 11 nov. 2026

Availability lets you limit how many rooms of a category can be sold online each day, or close a category completely, separately for each rule set.

Reading the grid

You find Availability under Units & Rates → Booking rules → Availability. The page shows one year at a time, with a row for each day and a column for each month. Use the arrows at the top to change year.

Every day shows three values, for example Max /1/ Thr:

• Maximum (left): the most rooms of this category that can be sold on the day. Empty means no limit.
• Middle number: how many rooms of the category are currently unsold. It updates by itself and you can't edit it.
• Threshold (right): the category closes when this many rooms are left. With a threshold of 1, the last room is never sold through the rule set.

A middle number of 0 means the category is fully booked or closed that day.

Setting availability

1. Go to Units & Rates → Booking rules → Availability.
2. Pick the Rule set you want to change, for example Public rule set. The values you enter apply to every channel that uses that rule set (see below).
3. Pick one or more Categories, for example Double Room (DBL). You can select several categories at once. The values are then shared across all the selected categories, so selecting every category lets you manage the total availability of the whole property.
4. Enter your Maximum and Threshold values using one of the three methods below.
5. Click Save in the top right corner. Nothing is applied until you save.

You can enter values in three ways:

A default value never overwrites a day you have set yourself, so you can set a general rule and then make exceptions for single days.

Closing a category for booking

To stop a room category from being sold for certain dates, set its Maximum to 0.

1. Go to Units & Rates → Booking rules → Availability.
2. Pick the Rule set. Choose the one used by the channels you want to close: for example Public rule set for your own booking page.
3. Pick the Categories you want to close. Select all of them to close the whole property.
4. Open Bulk update, choose the From and To dates and make sure all weekdays are ticked.
5. Enter 0 in Maximum and click Done.
6. Click Save in the top right corner.

The days now show 0 as Maximum and the category can no longer be booked on those dates through that rule set. To open the dates again, clear the Maximum (or set a new number) with a bulk update and save.

Only the rule set you picked is affected. If you also want to close the dates on other channels, repeat the steps for the rule sets they use.

Which channels use which rule set

Availability is saved per rule set, not per channel. Each booking channel uses a rule set like this, in order:

1. If the channel is linked to a rule set (Administration → Drop Down Lists → Booking channel), that rule set is used.
2. Otherwise, a channel marked Public uses the rule set of the Public channel.
3. Otherwise, a channel marked External (channel manager connections such as Booking.com or Expedia) uses the rule set of the External channel.
4. Otherwise, the rule set of the Intranet channel is used.

You can use the same rule set for several channels, so one change in Availability covers all of them. If a channel needs its own numbers, give it a separate rule set. A rate plan can also use a different rule set from its channel's: set this in channel management on the rate plan mapping page.

Bookings made by your own staff. Availability limits only apply to staff bookings if restrictions are switched on for your property and a rule set is assigned to the Intranet channel. When creating or editing a reservation, the Restriction policy decides what happens: Channel restrictions (default) follows the reservation's channel, Intranet restrictions always uses the Intranet rule set, and No restrictions ignores all rules. No restrictions is only available to users who have been given permission.

If something looks wrong

• A category is still bookable on a channel after you closed it. Check which rule set that channel uses (see above). You may have changed a different rule set.
• Closed on your booking page but open on Booking.com or Expedia (or the other way round). The two channels use different rule sets. Repeat the change for the other rule set, or link both channels to the same one.
• Your changes disappeared. Availability is only applied after you click Save. Save before you change year, rule set or category.
• A day ignores your default value. The day has its own value, which always wins over the default. Clear it or overwrite it.
• A staff booking was refused, or went through when it shouldn't. Check the Restriction policy on the reservation and that the Intranet channel has a rule set.
