Hot take: a positive P&L does not mean your business is actually profitable.
A P&L shows you the total. It does not show you which jobs made money, which ones lost money, or whether the profit you see is coming from one strong job covering the losses on three others.
Without job-level costing, a contractor can have a great-looking income statement and still be building a business on a shaky foundation. The profit looks real until the strong job is gone.
Job costing is what turns a P&L from a summary into a decision-making tool. LNH CPA helps contractors set up job costing in QuickBooks, run a monthly close, and understand exactly where the profit is coming from. Book a consultation at lnhcpa.com.
