Fractional Controller & Bookkeeping Services in Santa Monica

Controller-level financial leadership for Santa Monica businesses and Silicon Beach startups—a clean monthly close, audit-ready books, and the technical accounting expertise growing companies need. On-site in Santa Monica or fully remote.

Santa Monica sits at the heart of Silicon Beach, one of the densest clusters of startups, creative agencies, and digital-first brands in the country. Those companies tend to scale fast—and their accounting often can’t keep up. Founders find themselves with a bookkeeper who records transactions but no one senior to own the close, enforce GAAP, or get the books ready when investors or auditors come knocking.

That’s the gap BooksClose fills. Led by Stan Tronik, a CPA with 20+ years of controller-level experience across fintech, SaaS, and venture-backed companies, we give Santa Monica businesses the financial leadership of a full-time controller—without the full-time salary. Whether you need an interim controller during a transition, ongoing oversight, or help cleaning up and tightening your books, we work the way you do: in person on the Westside or seamlessly over the cloud.

Santa Monica FAQ

Common questions

Do you meet clients in person in Santa Monica?

Yes. We’re based in Los Angeles and regularly work on-site with Westside clients in Santa Monica, plus the surrounding Silicon Beach area. We also serve many clients fully remotely—whichever fits how you operate.

What’s the difference between an interim and a fractional controller?

An interim controller fills a temporary gap—for example, while you search for a full-time hire or during a leadership transition. A fractional controller is an ongoing, part-time arrangement. We offer both, and many Santa Monica startups start with one and move to the other.

We’re a startup preparing to raise. Can you get our books investor-ready?

Absolutely. Investor-ready, GAAP-compliant financials and a clean diligence package are core to what we do—we’ve carried high-growth companies through fundraising and acquisition.
