2. Missing deductions on trucks, tools, and parts purchases
3. Misclassifying technicians as 1099 contractors
4. Overpaying estimated taxes during slow months
5. Waiting until year-end for depreciation planning

## Built for Shops with Mixed Revenue Streams
Plumbing businesses rarely run on one type of work. Service calls, maintenance memberships, remodel jobs, replacement work, and emergency dispatch all hit the books differently. We keep the accounting organized so those lines are easier to review, cash is easier to manage, and tax moves can happen before profit gets trapped in the wrong places.
