Do I need a bookkeeper?
Short answer
Yes, the moment revenue passes $250-500K, or sooner if you hate the books. The hours you save will be worth more than the fee.
What they actually do
Categorize transactions, reconcile accounts, run monthly reports, and tell you when something looks wrong. Not your taxes, not your strategy. The plumbing, done right, monthly.
The cost-benefit
$300 to $800 a month for clean books that give you real numbers to make decisions on. Owners trying to save that fee usually miss tax deductions worth twice it, plus they make pricing decisions on bad data.
