Bookkeeping built for contractors

Construction bookkeeping is different from general small business bookkeeping. Job costing, certified payroll, prevailing wage tracking, and DIR record organization require a bookkeeper who understands how California contractors actually work.

J.P Bookkeeping has direct California public works and labor compliance experience. That means your job costs are tracked by project, your payroll records are organized for DIR reporting, and your CPA gets the documentation they need without spending their time reconstructing your records.
