Running a construction and tree service business, I find everyone wants a flat rate quote, no matter what the project entails. While fixed bid works in some applications, it doesn't work in every situation. A lot of customers don't want to understand that.
They willingly let plumbers, electricians, etc in that work strictly on a T&M basis, but then expect me to give a hard quote on every project, no matter what. Residing old barns can run into a lot of structural stuff needing replaced that you can't see until it's stripped. Pruning long tree lines takes a lot of time depending on the trees involved, how the debris is to be handled, site conditions, etc. I can't just give a price per ft as there are too many variables. I can give an approximate range, but then they instantly think I'll do the job for the lowest number mentioned. I no longer give a verbal number unless its going to be a fixed bid job. Also, I've become very clear on any written paper I hand over that it is either an ESTIMATE or FIXED QUOTE. Some folks get it, others don't. Then there's always that guy that wants to add on almost twice the workload after you start a project and expect you not to bill for it. "Well, you were out there anyways. It didn't add that much time..." That particular job added an additional 9 hours of work and he expected it to be included as part of my estimated work
I'm a bit sour after a couple of recent jobs. I'll get over it; just need to really watch how I say things and what goes on print.
