I can't believe the general consensus is not to have a budget. If you don't have a budget how do you know what your costs are and how what to charge for the particular job?
I dunno this is were quickbooks is great...tracking everything and being able to track expenses versus a budget is pretty simple. I can go back days, weeks, months, years....per project/job, track individual expenses...repairs, fuel, etc. So I can track how the variable (not fixed costs) are doing compared to what we expected.
I dunno if our repair costs are much higher than anticipated I'll be less likely to pull the trigger on new equipment purchase or whatever.
I just can't believe people don't have budgets...
