Too long, didnt read most replies.
Sales is all about the benefits outweighing the cost. If you cannot put across that your services outweigh the cost, you will lose. There is a technique in this, you hold off on speaking price until AFTER you've thoroughly described what you are doing. For Example:
Customer: HOW MACH DUZ IT COST BRO?
You: I will wash & wax your vehicle, clean your rims and tires, wipe your door jambs clean, wipe your gas tank door, and your trunk jamb. 100% done by hand using premium microfiber cloths that are so soft that you can smack a baby to sleep with them. All for , Just pull in over here.
Once theyre on the hook for at least something, I will tactfully point out something that we could correct for them.. something important such as:
"Btw Mr Customer, In addition to your wash I want to make you aware that we can remove those hard water spots from your windshield. It must be tough driving in the rain, especially at night, with your glass in that condition. We could either do it as an A La Cart add on for or you can take one of our detailing packages if you havn't had a good detail in a while"
or
"Btw Mr Customer, I noticed your headlights are severely yellowed, it must be tough for you to see driving at night. We could restore your lenses to like new condition allowing more light to pass through. This will increase your visibility, and also allow others to see you better as well."
Another thing you should be aware of, is that most customers are bringing you their daily drivers, and are not expecting a concourse detail, or a multi-step paint correction. IF you're trying to sell multi-step corrections to the average person you're going to lose out. I'm not a fan of AIO "details", I havn't found an AIO that'll protect as well as a dedicated wax or sealant like 845 or Klasse HGSG, and I'm all about keeping that car protected and harvesting repeat business.
Try making a detail package thats a one step polish, then a wax or sealant. When customers compare you to "Those guys", explain why your process is superior to an AIO and will outlast that form of protection. build value in that your first step will be dedicated to removing as many imperfections as you safely can while bringing out the best gloss, and how your wax or sealant will lock that look in, instead of just wearing off within a few short weeks leaving their vehicle open for more surface contamination.
I hope this helps.
