I don't bait and switch like some of you guys do.
You're supposed to clean the client's carpet NOT their wallet!!
That table can be turned on a dime. It can easily be argued that all inclusive pricing robs a great many of your customers, and makes those with less "service" need, subsidize those that have more " service" need.
You simply can not say that it does not cost you more as a business in time and materials to pre-treat, and on heavily soiled carpets use a rotovac (or any rotary tool) than it does to clean with a floor wand only. Pretreatments cost money - it takes time to apply them. Rotary tools cost money, require higher maintenance, consume more chems, and take longer to clean with than a wand.
So in turn - with a flat rate not considering any individual customers specific needs - you have to account for those costs (in one way or another) on all jobs, and then you have a situation where some people are paying for things they do not need. A customer who cleans 2x yearly with lightly soiled nylon doesn't need pretreatment, nor rotary cleaning, isn't benefiting from it in any way, and is paying for things they did not need. Your all inclusive approach is doing more wallet cleaning than an honest tiered service offering.
Custy 1 - Lightly soiled nylon, base clean, lower price.
Custy 2 - Moderately soiled oly, they need pretreatment, and are charged for what they needed above custy 1
Custy 3 - Heavily soiled poly, they need pretreatment and a rotovac, and are charged for what they needed above custy 1 & 2
And we haven't even gotten into stains, repairs, color correction/dye services, stretching etc. We have corrected stains and saved carpets hundreds of custy's through the years they were planning on replacing - so in the end, our OFFERING additional services - saved them thousands.
There is a distinct difference between offering needed services, and hard selling unneeded services - not every cleaner who offers tiered services is a "bait and switch". As long as potential costs are stated prior to booking - it is the farthest thing from it.
