QuickBooks job costing, AIA billing support, prevailing wage compliance, and retainage tracking for California roofing contractors.
California is one of the largest roofing markets in the US with significant variation: LA commercial and apartment construction, Bay Area tech campus and multifamily, Central Valley residential replacement, San Diego military and commercial. California has strict contractor licensing through the CSLB (C-39 license), strong prevailing wage requirements via California DIR, and one of the most complex tax environments in the country. Union labor dominates large commercial roofing in LA and the Bay Area.
California CSLB C-39 licensing, DIR prevailing wage, and union labor requirements make California roofing one of the most compliance-intensive markets in the US — bookkeeping must support all three.
Every California roofing job gets its own QuickBooks Project. Every invoice, bill, and expense tagged to the correct job. Monthly Project Profitability report shows gross margin on every completed job — so you know which work is worth bidding more of.
Retainage held on California jobs tracked in a dedicated QuickBooks account — visible on your balance sheet, aged monthly, flagged for collection when jobs complete. Most contractors we onboard have $40K–$120K in untracked retainage.
Two reports by the 10th of every month: company P&L and per-job profitability sorted by gross margin. Reports that drive real business decisions — not just annual tax filing.
Every sub paid over $600 in California tracked year-round. Clean 1099 list ready January 31st — no scramble, no missing payments, no IRS exposure.

California contractors on public projects must pay DIR-established prevailing wages, submit certified payroll weekly via eCPR, and maintain detailed labor records. QuickBooks must track labor costs by job, by wage classification, and by pay period to support eCPR reporting. Non-compliance can result in substantial penalties.
California contractors typically pay $500–$1,200/month in LA or Bay Area. JobCostBooks provides roofing-specialist bookkeeping for $600–$1,800/month — competitive with California rates.
