San Diego’s diverse economy, from pioneering biotech firms in Sorrento Valley to defense contractors near Miramar and thriving hospitality businesses along the coast, demands sophisticated financial leadership. Yet most growing companies can’t justify a $400,000+ full-time CFO. That’s where Weekly Accounting’s fractional CFO services transform the game, delivering enterprise-level financial expertise to San Diego businesses starting at just $1,500 per month.
Our tech-enabled approach gives you 52 feedback loops per year instead of the traditional 12, ensuring you never fly blind between monthly reports. Whether you’re scaling a SaaS startup in Mission Valley or expanding your e-commerce brand from Carlsbad, you get the strategic financial guidance that’s helped our clients raise over $200 million in the past two years.

A fractional CFO provides part-time strategic financial leadership, typically working 10-40 hours monthly while delivering the same caliber of expertise as a full-time executive. San Diego businesses save 60-70% compared to full-time CFO costs while gaining flexibility to scale services up or down based on growth phases.
This model particularly resonates with San Diego’s innovation economy. A La Jolla biotech preparing for Series A funding might need intensive CFO support for three months, then scale back to maintenance mode. A Downtown digital agency winning military contracts needs surge capacity for compliance and reporting without permanent overhead. Even established Chula Vista manufacturers use fractional CFOs to modernize financial systems without disrupting operations.
The sweet spot? Companies between $2 million and $50 million in revenue who need strategic financial leadership but can’t justify, or don’t need, a full-time executive.
The math is compelling. While a full-time CFO in San Diego commands $250,000-$350,000 base salary plus benefits, bonuses, and equity, fractional CFO services deliver the same strategic value for $18,000-$108,000 annually. You’re not paying for idle time or office politics, just pure financial expertise when you need it.
