How does availability work? Will I get double-booked?

The quantity you set IS your availability. Rennt subtracts confirmed bookings automatically.

Rennt does not have an "availability calendar" you have to maintain. The quantity you set IS your availability, and we do the arithmetic.

How it works#

Say you own 3 bounce houses, so you set Qty to 3 on that product.

  • Someone books one for Saturday → 2 left for Saturday.
  • A second person books two for Saturday → 0 left. Saturday now shows as unavailable for that item, automatically.
  • Sunday is untouched. It still shows 3.

Stock is held per date, and only from the moment you Confirm the booking. A booking still sitting as a Request does not hold anything.

Set Qty to what you can actually rent out at once — not what you own. If you own 3 tents and one is torn, set 2. Rennt cannot know about the torn one.

The one way you can still double-book#

Phone and text orders you forget to enter.

Rennt can only protect stock it knows about. If someone calls and books your last bounce house, go to Bookings → + New booking and enter it right then. Thirty seconds, and it closes the only real hole in the system.

Blocking off dates#

Going on holiday, or the gear is booked for a private job? Use Availability & blackout dates in Inventory to block a date range so nothing can be booked in it.
