Bookkeeping, Payroll and Tax Services for San Diego Small Businesses
San Diego runs on three or four different economies stacked on top of each other — biotech grant cycles, defense contract billing, tourism seasonality, and a supply chain that crosses into Tijuana and back. Fiscal Integrity Group keeps the books, payroll, and tax filings behind all of it running clean, whether you are two people in Sorrento Valley or fifty people on a government contract.
A County Built on Four Engines
San Diego is not a single-industry town. The businesses we work with here cluster around four distinct economic pillars, and each one demands a different kind of financial work.
Life Sciences
San Diego is the country's second largest biotech hub after Boston, home to more than 1,400 life science companies packed into a corridor running from Torrey Pines through Sorrento Valley and Carmel Valley. Most headlines go to anchor tenants like Illumina or Neurocrine, but the actual client base is smaller — contract researchers, device startups, and lab services vendors who live and die by burn rate and the next grant milestone. Their books have to hold up to due diligence on a timeline they do not control.
Defense
Roughly a quarter of the county's entire economy, and about the same share of its jobs, traces back to defense spending. That built a deep bench of contractors and subcontractors around the Navy and Marine Corps presence here, and 2026 has already brought a fresh wave of investment into the drone and defense tech side of it. Government contract accounting has its own rules, and getting cost segregation and billing wrong on a federal contract is a very different problem than getting it wrong on a retail invoice.
Tourism
Tourism is San Diego's third largest economic engine — over 26 million visitors and more than 5.6 billion dollars in visitor spending most years, and the county consistently posts the highest hotel occupancy in California. For a restaurant, hotel, or tour operator, that means real seasonality in the books, cash flow that swings hard by quarter, and payroll that has to flex up and down without falling out of compliance.
Cross-Border Trade
San Diego and Tijuana form what is genuinely the busiest binational economic zone in the world. Aerospace, medical device, and semiconductor manufacturers move components back and forth across the border as products get assembled and finished, and that corridor supports roughly 95,000 local jobs in the industries built around it. If your supply chain or your customer base crosses that line, your books need someone who has actually done it.
Why generic bookkeeping fails here
A bookkeeper who has never tracked an R&D credit, never segregated defense contract costs, and never reconciled a cross-border operation will leave real money on the table and create real compliance exposure.
Your Books Should Not Be the Hardest Part of Your Week
San Diego owners already juggle enough. Between grant reporting deadlines, contract compliance reviews, and a seasonal tourism swing, the last thing you need is a set of books you cannot trust.
- Grant spend and R&D costs lumped into one messy category
- Contract costs that would not survive a government audit
- Cross-border transactions sitting uncategorized for months
- TOT and sales tax filings that never quite match the books
- Paying premium San Diego rates for generic bookkeeping
- No idea which projects are actually profitable
