You can be the best tradesman on the job and still lose money, because the trade and the business are two different skills. Nobody runs an apprenticeship in entity structure, workers compensation classification, or what to do when a customer stops answering the phone after an estimate.

These guides cover the operational side of running a trade business: the legal and tax foundation, the paperwork that protects you when a job goes sideways, and the systems that turn a first customer into a repeat one.

Written from the position of someone who got several of these wrong first and had to fix them in public.
