What Matters for Contractors

AI expense categorization saves 5-10 hours per month by automatically sorting transactions into the right accounts.

Integration with your FSM (Jobber, ServiceTitan, Housecall Pro) eliminates double data entry.

Job costing reports show profitability per job, per tech, and per service type.

Cash flow forecasting prevents the cash crunches that kill contractor businesses.

Start with QuickBooks unless you have a specific reason not to. It integrates with every contractor tool on the market.

Worked Example: Accounting Software ROI

QuickBooks Plus at $90/month. AI expense categorization saves 8 hours/month in manual bookkeeping = $400/month saved (at $50/hour). The HVAC company that recovered $23,000 in missed deductions: that's $23,000 ÷ $1,080/year in software = 21x ROI on the software alone. Cash flow forecasting prevents the overdrafts and late payments that cost contractors $500-2,000/year in fees and penalties. Total ROI: 25-30x when you include time savings, deduction recovery, and fee avoidance.

What Not to Do

  • Don't use a personal bank account for business. Mixing personal and business finances makes tax prep 5x harder and increases audit risk. Open a business checking account and use it exclusively.
  • Don't skip expense receipt scanning. A shoebox of receipts at tax time costs you thousands in missed deductions. Snap photos of receipts immediately - QuickBooks and FreshBooks both offer receipt scanning.
  • Don't reconcile annually. Reconcile bank statements monthly. Catching errors in January that happened in March costs 10x more time to fix than catching them in April.
  • Don't ignore job costing. Revenue minus expenses = profit. But which services are profitable and which lose money? Without job costing, you're guessing - and might be subsidizing unprofitable work.
  • Don't DIY taxes past $300K revenue. A CPA who specializes in contractors costs $2,000-5,000/year but saves you $5,000-20,000 in missed deductions and tax strategy.
