This is our company's first year cutting grass. We only accepted a small client base (10 accounts) for our first year. When giving the initial proposals we charged anywhere from 27-30 $'s per cut. We bill on a monthly basis and even have a WEB site where the customer can view their current bill for the month. When we gave out the initial proposals we didn't mention anything about tax. When we sent out our first bill's last month we had one customer throw a fit and actually just dropped us today. Instead of their expected $54 they received a bill for $57.24. No one else had a problem with it. To avoid future problems I will include a "not including tax" on the estimate. Do you think we misrepresented the customer by not showing tax on the $27/cut proposal or is this just a cranky customer?
