With the latest WebReserv release, it is now possible to name your products/rooms/units individually. This allows you to manage and track reservations and utilization at a completely new level. For example, you can track now only what your customer reserves, but you can track exactly what unit is rented out and returned.
To name your products, go to setup -> products and reservation rules -> product details. In the list you can name each product. Typical names are room numbers (for hotels), tag numbers (car and RV rentals), serial numbers (equipment) and so forth.
When a reservation is made, you can quickly see which unit(s) that has been assigned, and if needed you can reassign the units as needed.
