Construction Bookkeeping Cost: The Quick Answer
Professional construction bookkeeping in Los Angeles typically costs $400–$2,000/month depending on your company size, number of employees, active projects, and services needed. Here’s the breakdown by contractor size:
- Solo contractor / sole proprietor: $400–$550/month
- Small contractor (2–5 employees): $550–$800/month
- Mid-size contractor (6–15 employees): $800–$1,300/month
- Larger contractor (15–30 employees): $1,300–$2,000/month
- Bookkeeping catch-up (one-time): $800–$3,500 depending on how far back
- QuickBooks setup from scratch: $500–$1,500 one-time
What Affects the Cost of Construction Bookkeeping?
1. Transaction Volume
The number of bank transactions, bills, invoices, and expenses per month is the biggest cost driver. A solo contractor with one business checking account and 50 transactions per month costs far less to service than a 10-person contractor with 3 bank accounts, 400+ transactions, and 20 active vendors.
2. Number of Employees & Payroll Complexity
Payroll is labor-intensive, especially in California. The more employees you have, the higher the bookkeeping cost. Certified payroll (required for California public works) adds additional complexity and cost — typically $150–$300/month depending on the number of projects and employees requiring certified payroll reports.
3. Number of Active Projects
Job costing multiplies the complexity of bookkeeping. Every transaction needs to be assigned to a project. Tracking 2 active jobs is simple; tracking 15 simultaneously requires significantly more time. Most bookkeepers price job costing as either a flat-rate add-on or a per-project fee.
4. Subcontractors
Managing subcontractor payables, W-9s, COIs, lien waivers, retainage payable, and 1099s adds meaningful time to monthly bookkeeping. GCs with 10–20 active subs pay more than specialty subs with no lower-tier subcontractors.
5. WIP Schedules
Monthly Work-in-Progress schedule preparation is a specialized skill that adds $100–$300/month to typical bookkeeping costs depending on number of projects. This is money extremely well spent — WIP schedules directly impact your bonding capacity.
6. Catch-Up / Cleanup Required
If your books are behind or messy, there’s typically a one-time catch-up fee before regular monthly service begins. We charge flat-rate catch-up fees based on scope after a free assessment — no hourly billing surprises.
Construction Bookkeeping Cost vs. In-House Bookkeeper
Many LA contractors ask whether they should hire an in-house bookkeeper vs. outsource. Here’s the honest math:
In-House Bookkeeper (Los Angeles)
- Salary: $48,000–$65,000/year
- Payroll taxes (employer): $6,000–$8,000/year
- Health insurance: $5,000–$10,000/year
- Workers’ compensation: $1,000–$2,000/year
- Paid time off (sick + vacation): $3,000–$5,000/year in lost productivity
- Training, software, recruiting: $2,000–$5,000/year
- Total true cost: $65,000–$95,000/year
And that in-house bookkeeper almost certainly does NOT have specialized construction bookkeeping expertise.
Outsourced to Bookkeeping Champs
- Monthly bookkeeping: $550–$1,300/month
- Annual cost: $6,600–$15,600/year
- No payroll taxes, benefits, PTO, or workers’ comp
- No recruiting or turnover risk
- Instant construction expertise — no training required
- Annual savings vs. in-house: $50,000–$80,000/year
The ROI of Proper Construction Bookkeeping
The cost question misses the bigger picture. Proper construction bookkeeping doesn’t just cost money — it makes money. Here’s how:
Better Bidding = Higher Win Rate & Margins
With proper job costing, you know your true cost by job type, trade, and project size. Contractors who know their numbers bid more accurately — not too high (and lose to competitors) or too low (and lose money). Most contractors who implement proper job costing improve their margins by 3–8% within the first year. On $1M of revenue, that’s $30,000–$80,000 more profit.
Higher Bonding Capacity = Bigger Projects
Clean WIP schedules and professional financial statements directly increase your bonding limits. Going from a $500K single bond to a $2M single bond opens up an entirely new tier of commercial and public works projects. A single larger contract can generate more gross profit than an entire year of smaller work.
Tax Savings
Disorganized books = missed deductions = higher taxes. Professional construction bookkeeping typically saves contractors $5,000–$25,000/year in taxes through properly documented deductions for vehicles, equipment (Section 179), tools, home office, insurance, and retirement contributions.
Faster Collections
When your billing is accurate and your AR tracking is tight, you get paid faster. Even a 10-day improvement in average collection time on $500K of annual billings frees up $14,000 in cash flow.

Frequently Asked Questions About Construction Bookkeeping Cost
Is construction bookkeeping tax-deductible?
Yes — 100%. Bookkeeping and accounting fees are fully deductible as ordinary and necessary business expenses for contractors. A $700/month bookkeeping expense saves you roughly $200–$280/month in taxes (depending on your tax bracket), making the effective cost even lower.
Do you charge hourly or flat-rate?
We charge flat monthly rates — no hourly billing surprises. You know exactly what you’ll pay every month. The only exception is one-time catch-up projects, which we quote at a fixed price after a free assessment.
Can I start with a lower plan and upgrade later?
Absolutely. We start wherever makes sense for your business right now and scale with you. Many clients start with basic monthly bookkeeping and add payroll, WIP schedules, and subcontractor management as their business grows.
Is there a setup fee?
There is no setup fee for clients starting with a clean or reasonably organized QuickBooks file. If your books require significant cleanup before we can begin monthly service, we quote a one-time catch-up fee — always flat-rate, never hourly.
How does your pricing compare to other LA bookkeepers?
Generic LA bookkeepers who don’t specialize in construction typically charge $300–$600/month for basic bookkeeping — but without job costing, WIP schedules, certified payroll, or construction expertise. You end up paying more to your CPA at tax time to clean up the mess, and leaving significant tax savings and financial insights on the table. Specialized construction bookkeeping delivers more value, not just more cost.
