A 2 or 3 bay self serve with an IBA may not have the revenue to compensate full time management/maintenance personnel. A lot of the sell sheets for self serve and IBA equipment, as well as general information on “building a self serve car wash” boasts the advantage of it not being a “hired labor” intensive model. I know many self serve operators are successful hiring full time management because they are pulling in enough to do so, but many of the locations I have seen would not be profitable, or at least sufficiently profitable, with full time employees. A lot of it is valuing your own time. If your wash is netting 80k - 100k, do you want to basically split that with employees? With that time, are you making more in some other business venture you may be involved in? Is the free time you get having the wash maintained by someone else worth that to you? Everyone is different where they draw that line. To generate a full time salary for an employee, you will need to require them to have sufficient and substantial hours on site, which can generally be done in a fraction of that time by an owner operator. It’s really about finding an acceptable balance and obviously gets tougher with more locations and distance.
