realised i undercharged a job by about 40%
did a repair last week. new tap, some pipe work took me a few hours. charged what i thought was fair. then i sat down and added up what i actually spent on parts and fuel. plus my time. came out way over what i charged.
feel like an idiot. this keeps happening cause i never track what im spending in the moment. i just guess and hope.
i know i need a better system. just something simple that tells me if im actually making money.
anyone else do this or am i the only one who cant do basic math
