The Brick Iron has a lot of in-house rentals like tables, chairs, and linens, and would like to be able to set a par of these so they know how many are in use per event base on their inventory in-house. i.e. when you create a menu items (i.e. 60" table rental, be able to add total quantity in-house as a part number like "10" and if an event tries to book 12 of them, it will flag or show an error. Additionally, if one event reserves 8 and another event reserves 4 on the same day at the same time, it won't let you book them for the newer event (it will flag a message like 2 available ))
