Bookkeeping, job costing, and fractional CFO services built exclusively for US solar and roofing companies — so you always know where the business stands financially.
Revenue looks fine. But without per-job financials, you can't see which installs made money, which crews are profitable, or where cash actually went last quarter.
A general bookkeeper doesn't understand ITC credits, job costing for installs, or how AccuLynx workflows translate to financial reporting. We do.
Onboarding is fast. Operations run on autopilot from there.
30-minute deep dive into your current books, tax position, software stack, and financial gaps. No pitch — just honest findings, free.
We audit and fix your existing books, build the right chart of accounts for your trade, and integrate your CRM and job management software.
Reconciliation, payroll, job costing, tax filings, and reporting delivered every month — with a short video walkthrough of your numbers.
Cash flow forecasting, profitability analysis, bank-ready reports, and strategic guidance to help you scale confidently.
We don't serve every business. We specialize exclusively in solar and roofing — which means faster onboarding, fewer questions, and more accurate books from day one.

"Their team knows solar inside and out. They caught ITC errors our previous CPA missed for three years straight."
GSC transformed our financial operations. The monthly job costing reports alone changed how we bid on projects — we cut two underperforming install crews and grew revenue by 22%.
"Multi-state payroll used to give me nightmares. Now it's completely off my plate — handled perfectly every month."
We operate crews in Texas, Oklahoma, and Louisiana. GSC manages all state compliance, 1099s, and quarterly filings. Not a single penalty or late filing since we switched.
"We got a $500K credit line approved because GSC made our books look exactly how lenders want to see them."
Before GSC, three banks turned us down. Within 3 weeks of working with them, our financials were clean, organized, and presented correctly. We got the line approved the next month.
"Finally know which roofing jobs are profitable. GSC's per-job reporting completely changed how I run my business."
I used to price jobs by gut feel. Now I have real margin data per project type, per crew, per region. We cut our worst-performing contracts and grew net profit by 31% in one year.
