You're profitable on paper, but your bank account says otherwise, sound familiar?
If you're a construction owner, general contractor, or subcontractor, you've probably experienced this frustrating disconnect. You look at your QuickBooks income statement, see a healthy profit margin, and wonder why you're still struggling to make payroll or cover material costs. The problem isn't your business, it's how your financial reports are set up.
Standard QuickBooks income statements are designed for retail stores and service businesses, not project-based construction work. They show company-wide profitability but hide the critical details you need: which jobs are making money, which ones are bleeding cash, and where your costs are really going.
In this article, we'll walk you through exactly how to streamline your QuickBooks income statements so they actually reflect the reality of your construction business. You'll learn how to set up job-based reporting, track the metrics that matter, avoid common mistakes, and finally get the financial clarity you need to make better decisions.
Why Standard QuickBooks Income Statements Fall Short for Construction
The Problem with Out-of-the-Box QuickBooks
QuickBooks is a powerful accounting tool, but it wasn't built with construction companies in mind. Right out of the box, it's configured for businesses that sell products or services in straightforward transactions think retail shops, consulting firms, or restaurants.
Construction doesn't work that way. Your business revolves around projects that span weeks or months, with costs hitting at different times than revenue. You deal with retention, progress billing, subcontractors, change orders, and materials purchased for specific jobs. Standard QuickBooks income statements lump all of this together into one company-wide view, making it nearly impossible to see which projects are profitable and which ones are costing you money.
Even worse, the default setup doesn't account for work-in-progress (WIP), percentage-of-completion revenue recognition, or the timing differences between when you bill clients and when you pay subcontractors. This creates a dangerously misleading picture of your financial health.
What Construction Owners Actually Need to See
To run a profitable construction business, you need income statements that answer these critical questions:
Which jobs are making money, and which ones are losing money?
Are my direct costs (labor, materials, subs, equipment) accurately tied to specific projects?
How much of my revenue has been earned versus billed?
What's my true overhead, and is it eating into my profits?
Am I pricing jobs correctly based on actual historical costs?
Without this job-level visibility, you're flying blind. You might think you're doing fine overall, but hidden losses on problem projects can quietly drain your profitability. By the time you realize what's happening, it's too late to course-correct.
Setting Up QuickBooks for Construction-Specific Income Statements
The good news? You don't need to abandon QuickBooks. You just need to configure it properly for construction accounting. Here's how to do it.
Step 1: Enable Class Tracking (or Locations in QuickBooks Online)
Class tracking is your secret weapon for job-based reporting. It allows you to categorize every transaction income, expenses, bills, checks by project or job. When you run your income statement, you can filter it by class to see the profitability of each individual job.
In QuickBooks Desktop: Go to Edit > Preferences > Accounting > Company Preferences, and check "Use class tracking for transactions." You can also select "Prompt to assign classes" to ensure nothing slips through the cracks.
In QuickBooks Online: Go to Settings > Account and Settings > Advanced, and turn on "Track classes." QBO also offers "Locations" if you manage multiple business locations or divisions.
Best Practice: Create one class for each active project. Use a consistent naming convention like "2024-Smith Residence" or "Job ID - Client Name" so your reports stay organized.
Step 2: Structure Your Chart of Accounts Properly
Your Chart of Accounts is the backbone of your financial reporting. For construction, you need to clearly separate direct job costs from overhead expenses.
Direct Cost Accounts (Cost of Goods Sold):
Labor (field wages, burden, payroll taxes)
Materials
Subcontractors
Equipment rental
Job-specific permits and fees
Overhead / Indirect Cost Accounts (Operating Expenses):
Office salaries
Rent and utilities
Insurance
Marketing and advertising
Office supplies
Professional fees
Keep your account names consistent and descriptive. Avoid creating too many accounts consolidate where possible to keep reports clean and easy to read.
Step 3: Configure Job Costing
Job costing is non-negotiable in construction. Every expense must be tied to a specific customer and job. This is how you track true project profitability.
Set up customers and jobs: In QuickBooks, create a customer record for each client, then create sub-jobs for individual projects under that customer.
Link expenses to jobs: When you enter bills, write checks, or record expenses, always assign them to the correct customer: job. Use the "Customer Job" field religiously.
Use Items for consistency: Set up Items (like "Field Labor," "Lumber," "Electrical Sub") that tie to your COGS accounts. This ensures every transaction flows to the right place on your income statement.
Step 4: Customize Your Income Statement Template
Now that your data is properly categorized, it's time to run reports that actually help you manage your business.
Run "Profit & Loss by Class" or "Profit & Loss by Job": These reports break down your income statement by project, showing revenue, costs, and profit for each job.
Customize columns: Add columns for budget vs. actual, or compare this month to last month.
Filter out noise: Exclude non-job income (like equipment sales or interest income) when analyzing job performance.
Save custom templates: Once you've configured a report you like, save it as a custom template so you can run it monthly without starting from scratch.
Key Metrics to Track on Your Construction Income Statement
Understanding your numbers means knowing which metrics matter. Here are the critical measurements every construction owner should track.
Gross Profit by Job
Gross profit tells you how much money you're making on each project after covering direct costs. This is your job-level profitability before accounting for overhead.
If a job shows negative gross profit, you're losing money on that project period. You either underestimated costs, experienced scope creep, or faced unexpected expenses. Either way, you need to know immediately so you can address it.
Gross Profit Margin (%)
Gross profit margin is a percentage that shows how efficiently you're managing job costs. Industry benchmarks vary, but most healthy construction companies maintain margins between 15-20%.
If your margins consistently fall below 10%, you have a serious problem. You're either pricing jobs too low, experiencing cost overruns, or both. This metric should be a red flag that triggers immediate action review your estimating process, tighten cost controls, or adjust your pricing strategy.
Overhead Percentage
Your overhead includes all the costs required to run your business that aren't directly tied to jobs office rent, administrative salaries, insurance, marketing, and so on.
Track overhead as a percentage of total revenue. A healthy goal is to keep overhead below 10-15% of revenue. If it's creeping higher, you need to either increase revenue or cut fixed costs.
Work-in-Progress (WIP) Considerations
Here's where construction accounting gets tricky. On a cash basis, your income statement only shows money that's hit your bank account. But that doesn't reflect economic reality.
If you've completed 60% of a $100,000 project but only billed $40,000, you've earned $60,000 in revenue even though you've only collected $40,000. You're underbilled by $20,000.
Conversely, if you've collected $80,000 but only completed 60% of the work, you're overbilled by $20,000. That money isn't really yours yet, you still owe work.
Your income statement needs to account for these timing differences. This is where WIP reports and percentage-of-completion revenue recognition come into play. Without adjusting for WIP, your income statement will mislead you about true profitability.
Common Mistakes Contractors Make (And How to Avoid Them)
Even with QuickBooks properly configured, contractors still make critical errors that distort their financial picture. Here are the most common mistakes and how to avoid them.
1. Not Assigning Costs to Jobs
This is the cardinal sin of construction accounting. When you don't assign expenses to specific jobs, they all dump into overhead. Your income statement will show inflated overhead costs and artificially high job profits.
The result? You think your jobs are more profitable than they really are, and you can't identify which projects are actually causing problems.
Solution: Make job assignment mandatory for every transaction. Train your team to always select a customer: job when entering bills or expenses. Run exception reports regularly to catch any transactions that weren't assigned.
2. Mixing Personal and Business Expenses
Using the business account for personal expenses (or vice versa) creates chaos in your financial reports. It inflates costs, makes reconciliation a nightmare, and can cause serious tax issues.
Solution: Maintain completely separate bank accounts and credit cards for business and personal use. If you need to move money between them, do it through proper owner draws or distributions not by randomly mixing expenses.
3. Ignoring WIP Reports
Many contractors run income statements without adjusting for percentage-of-completion. They look at cash collected and costs paid, but they don't account for earned revenue or incurred costs that haven't been billed or paid yet.
This creates wild swings in apparent profitability from month to month, making it impossible to understand true financial performance.
Solution: Run WIP reports monthly. Compare the percentage of work completed to the percentage of contract billed. Adjust your income statement to recognize revenue based on completion, not just cash collected.
4. Looking at Cash Basis Instead of Accrual
Cash basis accounting only recognizes transactions when money changes hands. For construction, this creates massive distortions. You might show huge profits one month (when you receive a big progress payment) and losses the next (when you pay subcontractors), even though the underlying economics haven't changed.
Solution: Use accrual basis reporting for accurate job costing. Accrual accounting recognizes revenue when earned and expenses when incurred, giving you a much clearer picture of true profitability.
From Data Chaos to Clear Insights
QuickBooks can absolutely work for construction companies but only when it's set up correctly. The out-of-the-box configuration won't cut it. You need job-based tracking, proper account structure, accrual basis reporting, and regular WIP adjustments.
The payoff is worth the effort. When your income statements accurately reflect job-level profitability, you gain the visibility to make smarter decisions. You'll know which types of projects to pursue, where to cut costs, how to price more competitively, and when to walk away from bad opportunities.
Small changes to your income statement setup create big results. Better visibility leads to better decisions, and better decisions lead to more profit simple as that.
