To cancel, open the booking from Bookings and press "Cancel" (on a confirmed or paid booking) or "Decline" (on a new request). The moment you do, any stock that was reserved for that date is released and can be booked by someone else.

What cancelling does — and does not — do#

• It frees the inventory instantly. The date reopens on your storefront.
• It keeps the booking in your history with a cancelled badge, so your records and Reports stay complete.
• It does not move any money. If the customer paid a deposit or a balance, that is still sitting in your ledger.
• It does not email the customer automatically. Tell them yourself — on Pro, open their record in Customers and use Send email so the message is logged.

Refunding what they paid#

Open the booking and scroll to the Payments ledger. Record a refund there for whatever you are returning — deposit, partial, or full — and pick the method (cash, card, check, other). If the payment came through Stripe, issue the actual refund in Stripe as well; the ledger entry in Rennt is your bookkeeping record. See the article "Refund a customer" for the full walkthrough.

Declining requests costs nothing#

A request never held stock in the first place, so declining one has no inventory effect at all. Decline anything you cannot serve rather than letting it sit — an unanswered request usually means the customer already booked elsewhere.
