Fractional CFO & Accounting Services in San Francisco

Most CPAs are spreadsheet-heavy, but ours is decision-focused.

Profit on paper doesn’t pay payroll. Without cash flow visibility, you’re always reacting.  Costs blur together and margins get squeezed without warning. One bad month or one slow client can disrupt everything.

Our team of CPA in California builds financial systems that match the way your construction business actually operates.

The Real Financial Challenges We Solve

These aren’t accounting problems. They’re business problems, and California businesses face them every day. The right financial partner can solve them before they become crises.

Cash flow gaps

Profit on paper doesn't pay the bills. We build cash visibility at the level your San Francisco business runs on — by job, client, month, or scenario.

Costs that don't reflect reality

Without accurate cost allocation, you can't price confidently or know what each part of your business actually produces.

Growth that outpaces infrastructure

Hiring or expanding without financial guardrails strains cash. We help you plan growth instead of reacting to it.

Unpredictable margins

We identify where profit is leaking and create pricing strategies that protect margin without slowing momentum.

Tax drag & missed deductions

Most California businesses overpay taxes because planning happens after the fact. We build a proactive strategy that reduces your bill legally.

“Basta & Co. was recommended to us after we had a series of bad experiences with other accounting firms. We look forward to tax season with Samy in charge of our complex tax situations.”

Sharon Ching

SLM Architecture and Design

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.

Elmira Esmaeili

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!


John Meloy

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!
