Welcome to San Mateo County's Open Checkbook!


Curious about what the County spends its money on? Our Open Checkbook is designed to allow you to easily find the information you want: by department, by expenditure type, or by payee.


This data includes checks made to payees totaling $5,000 or more as well as summarized payroll expenditures. (For detailed payroll costs, visit Government Compensation in California.)
