Availability tells OS Calendar which rooms can be booked on which dates. In the latest version this is managed by Inventory: for every room type and date, OS Calendar keeps the number of rooms and how many are booked or blocked. The back-end calendar views from earlier versions are still available per room.
Both approaches work the same in standalone mode and when linked with OS Property.
Open Components → OS Calendar → Pricing → Inventory.
Filter by property, room type, date range and stop-sell status. For each room type and date, the list shows:
| Column | Description |
|---|---|
| Total | Number of rooms of this type (from Number rooms in the room type). |
| Booked | Rooms taken by bookings. |
| Blocked | Rooms you have taken out of sale. |
| Available | Total − Booked − Blocked. |
| Stop Sell | Whether the date is closed for new bookings. |
Use the Bulk Actions / Controls area to select a room type and a date range, then:
| Action | Description |
|---|---|
| Generate | Create inventory for future dates so they can be sold. |
| Rebuild | Recalculate inventory from the existing bookings. |
| Block / Unblock | Take rooms out of sale for maintenance or owner use, or put them back. |
| Stop Sell / Open for Sale | Close or open dates for new bookings. Stop Sell can be limited to selected days of the week. |
You can also open a single entry (Edit Inventory) to change the quantity, the blocked rooms, Allow Overbooking and the Overbooking Limit. A Range Summary shows the minimum number of rooms available across the chosen dates.
Tip: Guests can only book a stay if every night of the stay has at least one room available. The number of rooms offered is the lowest availability among all nights.
From the Manage Room Types list, the Availability Calendar (calendar icon) button opens a visual calendar for that room.

Use the month and year selectors or the Prev / Next buttons to move between months. Click dates (or select several) and use Available or Unavailable in the toolbar.
When a visitor searches for a check-in and check-out date:
Tip: Dates that have a confirmed booking are reduced automatically. You do not need to update availability manually when a booking is made.
Needs verification: How the per-room availability calendar (Available / Unavailable dates) and Inventory interact when both are used. Use Inventory as the main tool for new setups.
