If you don't want to show availability for your products, you can disable availability by going to your Online reservations settings.
With real-time availability enabled, customers can only place orders when all items are available. Booqable will automatically reserve items for the rental duration provided.
When disabled, customers can always place orders, and orders will come in as concepts. Once the order comes into the Booqable backend you will need to mark them as reserved if all products are available.
