When Los Angeles and Ventura County contractors are looking for a bookkeeping partner, they have plenty of options — national chains, generic accounting firms, and software-only solutions. So why do so many choose Bookkeeping Champs? Because we’re not generalists. We were built specifically for contractors, and everything we do reflects that focus. Here’s what sets us apart and why it matters for your bottom line.
We Speak Contractor
Most bookkeepers don’t know the difference between retainage and a progress draw. They’ve never heard of AIA billing, prevailing wage compliance, or CSLB licensing requirements. At Bookkeeping Champs, construction and contracting is all we do. We understand job costing, how subcontractor payments work, how to track equipment depreciation, and the unique cash flow challenges of project-based work. When you talk to us, you don’t have to explain your business from scratch.
We’re QuickBooks ProAdvisors Who Know Construction
QuickBooks Online is the industry standard for contractor bookkeeping — but it has to be set up correctly to deliver value. A generic QuickBooks setup won’t give you job costing, won’t track retainage properly, and won’t generate the project profitability reports you need to grow. We set up QuickBooks specifically for contractors: proper Chart of Accounts, job costing through Projects, subcontractor 1099 tracking, payroll integration, and custom reports that tell you which jobs made money and which didn’t.
As certified QuickBooks ProAdvisors, we can also troubleshoot and clean up existing books — whether you’ve been DIY-ing it for years or inherited a mess from a previous bookkeeper.
Local Knowledge That Makes a Difference
We serve contractors across Los Angeles County, Ventura County, and the San Fernando Valley. That means we understand California-specific compliance requirements that out-of-state or generic bookkeepers miss: California prevailing wage rules, CSLB contractor licensing, California sales tax on materials, DIR (Department of Industrial Relations) registration for public works projects, and local business license requirements in cities like Los Angeles, Thousand Oaks, and Oxnard.
These aren’t obscure details — they’re obligations that can cost you thousands in penalties if you get them wrong. Our local expertise protects you.
Proactive Tax Planning, Not Just Tax Filing
One of the biggest complaints contractors have about their current bookkeeper or accountant is that they only hear from them at tax time. By then, the year is over and tax-saving opportunities have passed. Bookkeeping Champs takes a proactive approach: we do quarterly tax reviews, help you estimate what you’ll owe before Q4, and work with your CPA to implement strategies that reduce your tax burden legally — things like vehicle deductions, Section 179 equipment write-offs, home office deductions, retirement contributions, and S-Corp salary optimization.
Clean Monthly Books, Every Month
We close your books every month, reconcile your bank and credit card accounts, categorize every transaction correctly, and deliver a set of clean financial statements — Profit & Loss, Balance Sheet, and Cash Flow Statement. You always know where your business stands financially. No surprises. No shoebox of receipts handed to a tax preparer in April.
We Grow With You
Whether you’re a solo contractor doing $200K a year or a 20-person company doing $5M, we have a service tier that fits. As your business grows — adding employees, taking on bigger commercial projects, expanding to multiple trades — we scale with you. We’ve helped contractors go from solo operators to companies with multiple crews, and we understand every financial challenge along that journey.
What Our Clients Say
Our Los Angeles contractor clients consistently tell us the same things: they finally understand their numbers, they stopped dreading tax season, and their bookkeeping service pays for itself in tax savings alone. One general contractor in the San Fernando Valley saved over $28,000 in his first year with us by properly tracking deductions he’d been missing for years. Another HVAC contractor in Ventura County was able to bid more confidently once he had real job costing data showing him his actual labor and material costs per project.
Frequently Asked Questions
What types of contractors do you work with?
We work with all types of licensed contractors in California: general contractors, HVAC, plumbing, electrical, painting, flooring, fencing, roofing, landscaping, and more. If you hold a CSLB license and work in the LA or Ventura County area, we can help you.
Do I need to switch to QuickBooks to work with you?
We strongly recommend QuickBooks Online for contractors — it’s the best tool available for job costing and financial reporting. If you’re currently using another system, we can help you migrate. If you’re starting fresh, we’ll set it up correctly from day one.
How much does your bookkeeping service cost?
Our pricing depends on the volume of transactions and complexity of your business. Most small to mid-size contractors find our services cost far less than what they save in taxes and recovered income. Call us for a free consultation and custom quote.
