Subcontractors have unique bookkeeping needs that general contractors don’t always face. Managing multiple GCs, chasing down lien waivers, handling backup withholding, tracking equipment across job sites, and navigating California’s contractor licensing rules — it all adds up. Bookkeeping Champs provides specialized bookkeeping for construction subcontractors in Los Angeles, San Fernando Valley, and Ventura County.
We understand your world. Whether you’re an electrical subcontractor, plumbing sub, framing crew, or specialty trade — we handle the financial side so you can focus on the work. Call (818) 679-4451 for a free consultation.
Why Subcontractor Bookkeeping Is Different
As a subcontractor, your financial management challenges are unique compared to general contractors or other small businesses:
- Multiple GC Relationships — You may be working for 3–10 different general contractors simultaneously, each with different billing formats and payment schedules
- Lien Waiver Management — You need to track conditional and unconditional lien waivers on every job — and make sure your lower-tier subs provide them too
- Retainage Tracking — GCs often hold 5–10% retainage on your billings until project completion; this must be tracked carefully as an asset
- Certified Payroll Compliance — If you work on public works as a sub, you must submit certified payroll reports to the DIR independently
- Insurance & License Tracking — You need to stay on top of your own CSLB license renewals, workers’ comp audits, and COI requirements from GCs
- 1099 Obligations — If you use lower-tier subs or independent contractors, you have your own 1099 filing requirements
- Backup Withholding Risk — If you don’t have a W-9 on file for your subs, you may be required to withhold 24% of payments
Our Bookkeeping Services for Subcontractors
Monthly Bookkeeping & Job Costing
We track income and expenses by job so you know which GCs and project types are actually profitable. With proper job costing, you can make smarter bidding decisions and eliminate money-losing work types.
Accounts Receivable & Retainage Tracking
We track every invoice, every payment, and every retainage balance so nothing falls through the cracks. We can also help you draft professional billing applications that GCs pay faster.
Lien Waiver Administration
We maintain a lien waiver log for every project — tracking what’s been sent, what’s been received from your lower-tier subs, and what’s still outstanding. Proper lien waiver management protects your lien rights and satisfies GC requirements.
Certified Payroll for California Public Works
We prepare and file certified payroll reports (DIR Form A-1-131) for California prevailing wage jobs. As a sub, you are responsible for your own CPRs — even if your GC uses a compliance service for theirs.
Subcontractor & 1099 Management
We collect W-9s from your subs, track payments throughout the year, and handle all 1099-NEC filings at year-end. We’ll also help you determine which workers should be classified as employees vs. independent contractors under California’s strict AB5 rules.
Tax Preparation & Planning
Year-round tax planning to minimize self-employment taxes, maximize deductions for tools, vehicles, and equipment, and ensure you’re compliant with California FTB requirements.

Frequently Asked Questions for Subcontractors
Do I need separate bookkeeping from my GC?
Yes. As a subcontractor, you are a separate legal and financial entity. You are responsible for your own books, payroll, taxes, 1099s, and certified payroll filings — regardless of what your GC does.
What is retainage and how should it be tracked?
Retainage is the portion (typically 5–10%) that GCs withhold from your progress payments until project completion. It must be tracked as an accounts receivable asset so you don’t lose track of money owed to you.
Am I required to submit certified payroll as a sub in California?
Yes. If you work on California public works projects, you must submit your own certified payroll reports to the DIR through the eCPR system — independent of your prime contractor’s filings.
How does AB5 affect me as a subcontractor using helpers?
California AB5 uses the strict “ABC test” to determine worker classification. Construction subcontractors have specific exemptions, but they are complex. We can help you navigate proper classification to avoid costly misclassification penalties.
Can you help me catch up on back bookkeeping?
Absolutely. We offer bookkeeping catch-up services to get your records current, whether you’re 3 months or 3 years behind. Call (818) 679-4451 for a catch-up quote.
