Contractor books are messier than most: materials receipts from five suppliers, progress billing, retainage, subs to 1099, and job costing that decides whether you actually made money on that bathroom remodel. That mess is exactly why trades pay $2,000–$3,000/month for part-time bookkeeping — and exactly what AI now does for about $400.
What AI bookkeeping handles for a trades business
Receipt capture from the truck (photo → categorized transaction), invoice generation the day the job closes, bank and credit-card reconciliation, materials cost tracking by job, progress-billing schedules, and monthly P&L by crew or service line. A human professional reviews the output monthly — same model we covered in the 2026 bookkeeper cost breakdown.
The job-costing difference
Most small contractors find out a job lost money 60 days later, at month-end — if the books are even current. With transactions categorized to jobs as they happen, you see margin slipping while the crew is still on site. That visibility is routinely worth more than the bookkeeping savings.
The math for a typical shop
| Option | Cost /yr |
|---|---|
| Full-time bookkeeper (fully loaded) | $74,900 |
| Part-time / outsourced | $24,000–$36,000 |
| AI bookkeeping + monthly review | ~$4,800 |
