IDK, once again I think a bit different than everyone else. But before I get to that, let me respond to some things
Offered him 10% on corporate referrals Over time you will realize that if you do exceptional work, you wont need to discount your price. These days its difficult to find a tradesman that does good work. Once a client finds one, they are hard pressed to go elsewhere. So why offer a discount?
I can charge more in the future once I have more google reviews and referrals. Once again your relating what you charge (whether giving discounts or increasing prices) based on factors other than your exceptional work. Your exceptional work wont change so why are you fluctuating your prices based on other factors?
Then I applied fabric protector - didn't charge for this as it was first time customer. So if you would have charged for protector what would you have made?
The efficiency thread" and "$100/hr... yah its nice, but dont skimp on your procedures to get there. Once you eliminate one step, its easy to eliminate another and soon you are just like all the other cleaners in your area. Be different, set yourself apart from the others.
Why? Because once you get a following, you wont need to advertise. Your clients wont go anywhere else.
