I'm in my second season and last year I bid a job for $50.00. After the first cut I realized I had underbid. I did not considered the large amount of trimming and this customer as it turns out is very particular with his lawn. He had a construction project last year that added to the amount of mowing this year. I explained this to him and rebid the job this year and doubled his rate to $100.00. I did my research and am confident that my bid this year was competitive for the area. As expected he dropped me. In the future how should I handle this situation so a customer does not think I am jerking him around?
