We ran payroll for the Fortune 500. Now we run it for our neighbors.

For most of our careers, our founding team managed payroll and revenue operations inside some of the largest companies in America — millions of dollars moved on our sign-off and thousands of paychecks went out because our numbers were right. At that scale, every account reconciles and every deadline is met. We started Global Expert Systems because small businesses in our own community deserve that same rigor at a price they can plan around — the contractor doing invoices at midnight, the restaurant owner who finds out in April what she earned in June. Today, we keep the books for contractors, restaurants, salons, and shops across West Contra Costa from our home base in Hercules. We provide tax-ready financials for your CPA. Our commitments: 1. Your books should be boring: Surprises belong in birthdays, not bank reconciliations. 2. Flat pricing is honest pricing: Never hesitate to call because a meter is running. 3. Plain English beats jargon: No complex financial speak, just clear results. Book a Free Consult
