Hi.. Just my opinion.. I would step it up and go Credit/Debit and Bills in bays.. NO
COINS.. trash your quarter
changer for a Bill Breaker.. and the same with the Vacuums, Bills and Cards, NO
COINS.. ..you gotta spend it, to make it.. I have done what I just mentioned and it works.. I just remodeled a 6 Bay and 8 Vac Wash, with EVERYTHING Top of the Line..Air Dryers etc, and it did 188,000 last year after remodel.. this year heading for 230,000+.. I know that is not great revenue, but it's working so far, and simple to manage....I thought about adding a AutoMatic, but I have had them in the past, and they can be a Pain in the you know what.. Just my 3 cents..
Happy Car Washing,
Doug
