This excerpt from a short article by Kelly Sims, What Every Entrepreneur Should Know about Comparative Advantage, may help answer your question.
“Comparative advantage is a term used to explain the gains from international trade. It suggests that even if a country has an absolute advantage in the fabrication of all goods, it will maximize its wealth by specializing in those products in which it has the greatest advantage and trading for the others.”
Does this concept apply to small business like a carwash? In a sense, it does.
What an express wash does is trade off wand-bays to specialize on its greatest advantages; the offer of a hand-finish quality, stay-in-the-car, exterior wash, done in less than 4-minutes, at preferred pricing points and free-use services (vacuums). There is virtually no waiting line and the average total guest visit is eight minutes on property.
The truth of the matter is if you have a self-service facility with prototypical in-bay automatic you cannot compete against this effectively.
Instead, you stand the greatest chance to increase revenue by concentrating on the things at which you have the greatest advantage and outsource the rest.
Since most express washes are absent wands and
vending machines, you need to maximize the utility of your self-service business. This means mudders, boats,
fleet vehicles, etc. are your best friends as well as having bill acceptors in bays and offering high quality products, well-known brands are preferable.
If you believe $3.00 for the base wash is needed to compete in the automatic wash segment, you would need an in-bay automatic capable of a producing a legitimate 25 to 35 washes an hour as well as hand-finished quality 24/7, especially for vehicles that won’t fit on a conveyor.
You would need a POS capable of provide a smiling face and greeting, bilingual capable, having up-sell capability, connecting to the internet to provide
marketing information for
loyalty programs and dispensing
tokens if you want to offer free-use vacuums.
You would also want to use top package
marketing to drive high average sales. Wheel brightener, underbody, rust inhibitor, triple foam polish, paint sealant, rain repellant, spot-free and tire shine not only solves motorist’s car-care problems they also put on a good show for the customer.
Hope this helps.
