Services We Provide to Contractors

Bookkeeping Services

Construction bookkeeping services include accounts payable and receivable data entry, invoicing, paying bills, deposit recording and tracking, bank reconciliations, and general ledger maintenance. Each service is customized to meet the specific needs of your construction business - including Foundation Construction Software and QuickBooks. 

Clean-Up & Catch Up

No matter how far behind your construction books are, we get you cleaned up and caught up—fast. With deep experience in Foundation Construction Software and QuickBooks, we help California contractors fix missing or messy entries and bring their books fully up to date. We keep your construction bookkeeping on track so you can keep building.

Progress Billing Support

As contractor accountants, we handle it all: Schedule of Values setup, pay applications, retainage tracking, and lien management, so you don’t have to. Whether it’s progress billing, unit based, or time and materials, we make sure every invoice is accurate, on time, and documented right. This means faster payments, stronger cash flow, and less time chasing down what’s already yours. We speak the language of GCs, subs, and project managers and we keep your billing airtight from start to finish.

Certified Payroll

We provide certified payroll services for California and Davis-Bacon projects, preparing all required paperwork including DAS forms, Statements of Compliance, fringe benefit reporting, and prevailing wage documentation. We submit reports through the DIR or LCP Tracker depending on project requirements. We stay current with industry training to keep your payroll accurate and hassle-free.

Job Costing

If you don’t know what a job costs, you can’t price it right, and you can’t protect your profit. We build job costing systems that make sense for construction. Simple, accurate, and built to match the way you actually work.

Payroll Processing

We manage time tracking, garnishments, sick and vacation hours, labor cost allocation, payroll tax filing and reporting, and ensure accurate payroll data entry using your software.

Training is provided in Foundation Software, QuickBooks, and Sage with clear workflows built for construction.

With clear financials, they now bid smarter and make confident, data-driven decisions.
