Payroll made easy.


Your success is our priority.

Are you spending too much time on payroll? Spending too much on payroll services? Afraid of mistakes that may lead to IRS penalties?

As a small or mid-sized business owner, keeping your own books may seem like a daunting task. Your company’s success is the priority - let us handle the rest. TOPCO is determined to provide the best possible bookkeeping or payroll service online depending on your needs.

Whatever your payroll question is, we are here to help. We offer top quality service, 365 days a year.


Since ‘09.

TOPCO was launched in 2009 and has been growing ever since. Starting with only one client and expanding to a vast network the past decade, we remain dedicated to giving each client our undivided attention. Though we are based in the San Francisco Bay Area, we have expanded to other parts of California and neighboring states.

For us, good organization is key to good communication. Making sure your books are organized is of the utmost importance to us. We work closely with owners or CFO’s of businesses and their tax accountants. We also provide a full payroll service and integrate worker’s compensation.

We are your one stop shop for a flexible, organized, and, most importantly, reliable bookkeeper.


“Organization has been and will continue to be the key to our success.”
