Short Answer: The Industry Has Standards for the Work, Not for the Business
Tree care is one of the most carefully standardized trades in the world when it comes to the actual tree work. ANSI A300 says how a tree is pruned. Z133 says how the crew stays safe. ISA says who is qualified. TCIA audits the company against all of it.
None of them says what a healthy close rate is, how much of a crew's day should be spent driving, or how fast an invoice should leave. None of them says what share of revenue can go to payroll before the company stops making money.
The US tree trimming industry alone is worth about $39.5 billion across roughly 175,000 businesses (IBISWorld, 2026). Most are small, and most are run on experience rather than numbers. The ArboStar Standard is the operating standard that sits next to A300 and Z133, covering everything they leave out: how the business itself should run. It is not written in a conference room. It is drawn from how well-run tree care companies across the USA, Canada, Australia, New Zealand, the UK and Europe actually run their operations today.
