“Not until you spend the $50,000 - $100,000+ depending on how many vacs for vac systems, etc. can you understand what I’m saying.” “Did it increase self serv wash business?”
Best gain from free vacuum I’m familiar is $30,000 to $80,000. This was wand to POP conversion. Conversion cost about $80,000.
If conventional self-serve (i.e. 5 + 1), don’t expect much just from offering free vacuum alone.
Reason is as self-serve vacuum represents maybe 10 to 15 percent of sales.
If this was given away, it would require extra business equal to wand-bay or about 2,000 more cars per year through the in-bay just to make this up.
2,000 more cars a year (about 500 more individual customers) would require something major like subscription program or express in-bay to wash more cars an hour at higher average sales.
Whatever, the solutions are not cheap.
