A well-structured chart of accounts is the foundation of solid, long term construction accounting. Setting up your chart of accounts the right way is more consequential than you may think. Get your construction chart of accounts right from the start, and you’ll have clear, reliable numbers that will guide your management of your company. But if you don’t pay attention to all the details, every report you pull will be a little bit confusing, a little bit off.
Our guide walks through the key steps of how to build a chart of accounts that fits your contractor accounting structure.
What Is a Construction Chart of Accounts & How is it Different from Cost Codes?
It’s easy to confuse a chart of accounts with a cost code system, but they do two different jobs.
Your chart of accounts is the structure behind your balance sheet and income statement. You use it to track the overall financial health of your company. It provides a broad overview of what you own, what you owe, and what you’re earning.
Construction cost codes track costs at the job level. They are used to break down labor, materials, and subcontractor costs for a specific project so you can see how that job is performing.
Both systems are key to the overall financial health of your construction company and they should work together without getting tangled. If you mix job-related costs in with overhead in your chart of accounts, your reports get muddy fast. That leads to poor information, and poor information leads to poor decisions. Keeping job cost categories separate from your general ledger structure is one of the simplest ways to keep your books transparent.

Why Construction Accounting Needs its Own Structure
Construction companies have specific financial transactions that are unique to the industry. Retainage, or the portion of a payment your client holds back until the job is complete, should be recorded separately in your books. It’s the same with over-billings and under-billings, when you use percentage-of-completion accounting.
These unique financial instances are fundamental for how construction companies recognize revenue and manage cash flow. That’s why setting up your chart of accounts correctly is essential for every construction company. And it’s never too late to review your construction chart of accounts. Building it right saves you endless hours of reviewing poor data so you can always make decisions based on reliable numbers.
How to Build Your Chart of Accounts, Step by Step
Most charts of accounts follow the order of a balance sheet first, then an income statement. Here’s a simple numbering structure that works well for contractors, and the order to build it in.
Step 1: Start with assets (1000s). Assets are everything your company owns, including cash, accounts receivable, equipment, and retainage receivable.
Step 2: Set up liabilities (2000s). Liabilities are what you owe. It helps to flag which ones are due within the next twelve months, like accounts payable, payroll taxes, and principal payments on longer-term debt.
Step 3: Add equity (3000s). This covers common stock, retained earnings, and other ownership accounts. Remember: total assets should always equal total liabilities plus equity. That balance is what keeps your balance sheet balanced.
Step 4: Build out revenue (4000s). This is where your income from completed and in-progress jobs lives.
Step 5: Set up cost of revenues (5000s). This category deserves extra attention in construction. Cost of revenues (sometimes called cost of goods sold) directly ties your job costs to the revenue they generated, which is critical for understanding true project profitability.
Step 6: Add expense categories (6000s and 7000s). These are your overhead costs, including office administration, utilities, equipment depreciation, and supervisor salaries. This is where you record expenses that keep the business running but aren’t tied to a specific job.
Step 7: Include other income and expense (8000s and 9000s). This covers things like interest income and interest expense related to financing.
This structure gives you a construction GL setup that’s clean, consistent, and built for how contractors actually operate.
Handling Retainage and Percentage-of-Completion Entries
Two areas of accounting that can take a lot of time and pose many challenges are: retainage and percentage-of-completion accounting.
Make sure retainage is captured as a receivable, along with the income associated with it. If it’s missing from your books, your revenue picture will be incomplete.
You’ll also need accounts for costs in excess of billings and billings in excess of costs. These entries are necessary for percentage-of-completion accounting, and they belong on your balance sheet, not buried in a spreadsheet on the side. To understand exactly how this works, read our article on revenue recognition and percentage-of-completion accounting.
The One Rule that Matters Most: Stay Consistent
Once your chart of accounts is set up, the most important thing you can do is stay consistent. Use the same account structure across every job, every month, every year. Consistency is what makes your job costing accurate and your financial reports genuinely useful.
