Our CPA experts provide strategic accounting, proactive tax planning, and fractional CFO support to help Bay Area and California contractors understand job profitability, control equipment and hauling costs, anticipate cash needs, and plan taxes.
You can bid a site, but you can’t see what’s actually underground until you start digging — rock, contaminated soil, or a utility line nobody mapped. Our fractional CFO, accounting, and tax strategy practice works with excavation and sitework contractors across California, based in the San Francisco Bay Area, who need that risk reflected in their numbers, not absorbed by their margin.
We work with residential, commercial, and public works excavation contractors to track change order documentation, manage heavy equipment costs, and account for hauling economics that shift with every site.
The numbers we review together:
When several jobs are running at once, small misses in estimating, equipment utilization, or scheduling can quickly cut into margins and make it difficult to see which projects are actually producing profit.
Our team of CPAs and accountants helps excavation and sitework contractors understand where money is being made or lost, how labor and equipment costs are affecting each job, and how much working capital is needed to keep crews and equipment moving.
The Cost Risks Hiding Underground
Excavation and sitework jobs can look profitable on paper while equipment downtime, fuel costs, hauling, labor overruns, and unexpected site conditions quietly eat into the margin. We help California contractors get a clearer view of job performance, identify where costs are drifting, and make adjustments before those issues start putting pressure on cash flow and overall profitability.
Hitting rock, contaminated soil, or an unmapped utility line can undercut a bid before the job even gets going. We help organize change-order documentation and track related costs so unforeseen conditions are identified, billed, and followed through more consistently rather than disappearing into job margin.
Whether you’re importing or exporting dirt changes your cost structure job to job, and trucking costs move with fuel prices and haul distance. We track trucking, fuel, import/export volume, haul distance, and related costs by job so owners can see how hauling is affecting project margin.
Owning versus renting affects utilization, maintenance, financing, cash flow, depreciation, and project cost. We help model the total financial impact before a major equipment decision.
Stormwater and erosion-control requirements can add meaningful project costs. We help capture those costs in job reporting so they aren’t buried in general overhead when they belong to a specific project.
Certain off-highway fuel use may qualify for federal or California tax treatment depending on the facts and applicable rules. We review fuel usage and documentation as part of tax planning to determine whether any available treatment applies.
We’re the right fit for excavation contractors that:
We help contractors across the Bay Area and California move beyond basic accounting with stronger reporting, proactive tax strategy, and clearer visibility into equipment costs, labor, fuel, job margins, and overall project profitability.
San Francisco contractors preparing individual home sites for grading, utilities, and foundation work.
Bay Area firms managing larger commercial site development and infrastructure prep.
California contractors working government-funded road and infrastructure grading projects.
Firms specializing in trenching and installation for underground utility work.
Contractors focused on clearing and site prep ahead of other trades starting work.
The right financial strategy doesn’t just organize your books. It increases resilience and confidence.
Your financial setup should work the way you do — not the other way around. That’s when things finally make sense
Your numbers should help you answer:
Limited visibility into equipment utilization, fuel, labor, hauling, and job costs can make that growth harder to control. Better reporting and financial oversight help owners see which projects are performing well, where profit is being lost, and how to grow without putting unnecessary pressure on cash flow.
Senior financial leadership on a part-time basis. Strategy, forecasting, and financial decision-making, without the full-time salary.
Track base-contract revenue, change orders, labor, hauling, fuel, equipment usage, retainage, receivables, and overhead so monthly reporting reflects how excavation jobs actually perform.
Anticipate payroll, fuel, trucking, equipment payments, subcontractor costs, taxes, retainage, and collections so potential cash shortfalls are visible earlier.
Compare estimated and actual labor, trucking, fuel, equipment, materials, subcontractors, and site-condition costs by phase so margin problems show up before closeout.
We review entity structure, owner compensation, estimated taxes, equipment purchases, depreciation, fuel-related tax treatment, and available deductions throughout the year so tax decisions happen before deadlines limit your options.

What a great surprise! We were expecting to pay IRS over $10,000 in additional taxes but we ended up with $4,000 tax credits and paid nothing! Samy is amazing! He knows all the recent tax reforms and patiently explains them to us and applies the relevant tax deductible tools and strategies for our business and personal taxes.

As a new client I’m delighted to report that my interactions with Basta & Company have been excellent. I’m grateful for the invaluable assistance I’ve so far received from Basta & Company, and staff!

I cannot recommend Samy enough! He helped us with a very challenging 1031 exchange which allowed us to defer our capital gains taxes and purchase a new property. He returns e-mails and phone messages promptly and the best part is that he talks non CPA language to you in order to make sure you understand everything. If I could, I would give him 6 stars!
