Pricing risk vs time

[Mesterh]

I give a price for the finished job, be very clear about what that will be and manage the clients expectations, I.E. "We will remove the tree to near ground level, removing all arising, leaving the site clean and tidy. There will some marks on the lawn, but not major damage, there will be no damage to walls, fences, etc"

 

If upon completion they question the price I ask which part of the job has not been completed.

 

That's The best way to go imo.

State what you are doing and price the job accordingly. If you start to get too technical ie it will take x amount of seconds with x amount of men then the customer can come back at you.
