Construction Chart of Accounts: The Accounts Behind a WIP Schedule Your Surety Will Accept

A general contractor bids a job that needs a larger bond than the surety has approved before. The surety asks for a work in progress (WIP) schedule: every open job, its contract value, cost to date, estimated cost to finish, billings to date, and whether the job is overbilled or underbilled. The contractor opens QuickBooks and finds one revenue account, one cost of goods sold account, and an accounts receivable balance that mixes retainage with ordinary invoices. Nothing on the schedule can be filled in from the books. It gets built in a spreadsheet, from memory, and the surety reads it with the trust that deserves.

The schedule is not the problem. The chart of accounts is. A WIP schedule is built job by job from contract values, estimated costs to complete, costs to date and billings to date. When job costs are tagged by job and the over- and underbilling accounts are posted every month, the books agree with the schedule. This guide covers those accounts, the three entries that fill them, and what each one does to the income statement and balance sheet.

Why a generic chart breaks down for contractors

A generic chart has no account for billings that run ahead of or behind the work, so revenue usually gets recorded when an invoice goes out. On a twelve-month contract billed monthly, that timing is wrong in both directions. A contractor who front-loads billings has collected cash for work not yet done. A contractor who is slow to bill has done work the books do not show. Under GAAP (Generally Accepted Accounting Principles), revenue on a long-term contract is recognized as the work progresses, usually in proportion to costs incurred against total estimated costs. The Internal Revenue Service applies the same percentage-of-completion idea to larger contractors for tax, and its Construction Industry Audit Technique Guide walks examiners through it job by job.

The generic chart also has one place for receivables and one for payables. Retainage, the slice of each billing the customer holds back until the job is accepted, sits inside accounts receivable and looks like a late payment. The retainage you hold back from subcontractors sits inside accounts payable and looks like a bill you have not paid. Both distort the aging reports a surety reads alongside working capital.

Finally, a single cost of goods sold line cannot tell a labor overrun from a materials overrun. Job costing needs direct costs split by category, and it needs the office rent and the estimator's salary kept out of job cost entirely.

There is a tempting shortcut: keep the books on a cash basis and let the tax return sort it out. It fails at the first bond application. A surety reads accrual statements, and most ask for a reviewed or audited set once the bond program passes a certain size. The chart of accounts is the cheapest part of that requirement to get right, and the one that cannot be fixed at year end by the accountant alone.

Cost and cash flow through the job accounts

Every dollar on a job touches these accounts in this order. Revenue and cost reach the income statement on the way through; the balance sheet holds whatever has not settled yet.

The accounts that do the work

These are the accounts that do the work for a contractor. Most of them are not in a generic chart. The numbers, names and types are a suggested layout; nothing on this page imports into QuickBooks. The account names call retainage "retention"; the two words mean the same thing.

The four cost accounts in the 5000 range are direct job costs and belong in gross profit. Rent - Office sits in the 6000 range as general overhead. Keeping that line intact is what makes gross profit by job a number you can defend to a surety, because it contains only costs that would not exist without the job.

One decision the owner has to make once, and then hold to: what counts as job overhead. A site trailer, a project manager's time, a dumpster, and the fuel for the crew truck all vanish when the job ends, so they belong in the 5000 range and get tagged to the job. The yard lease, the estimator, and the bookkeeper stay whether the job exists or not, so they belong in the 6000 range and never get tagged. A chart that draws that line makes the job cost report and the bid estimate use the same definition of cost, which is the only way to learn anything by comparing them.

How the accounts get booked

Take one commercial job: a $500,000 contract with an estimated total cost of $400,000. Figures are illustrative throughout.

In month three the contractor bills $100,000 against the schedule of values. The contract lets the customer hold 10 percent until final acceptance. The billing is split at the moment it is recorded, so retainage never hides inside ordinary receivables.

The same month, the electrical subcontractor submits a $40,000 pay application. The contractor withholds 10 percent from the sub, exactly as the customer withholds from the contractor. The full $40,000 is a job cost today; only $36,000 is payable today.

At month end the bookkeeper compares work performed to work billed. Cost to date on this job is $180,000 against the $400,000 estimate, so the job is 45 percent complete and earned revenue is $225,000. Billings to date are $250,000. The contractor has billed $25,000 more than it has earned, and that $25,000 is a liability: an amount billed for work still owed to the customer.

Entry 3 records the WIP schedule's result for this job. The total of the schedule's overbilling column is the balance in 2241, and the total of its underbilling column is the balance in 1385. When job costs are tagged by job and those two accounts are posted every month, the books agree with the schedule.

The underbilled case deserves its own sentence, because it is the one owners ignore. A job that has earned more than it has billed is not a good sign to a surety. It usually means one of three things: the billing is late, the estimate of total cost is too low so the percentage complete is overstated, or the job has costs on it that the customer will never pay for. All three reduce cash. A growing balance in 1385 is the earliest warning the books can give, and it only exists if the account does.

When the job reaches final acceptance, the retainage releases. The $10,000 in Retention Receivable moves to Accounts Receivable - Progress Billing with a debit to 1201 and a credit to 1211, and the invoice goes out. The same day, the $4,000 in Retention Payable becomes a bill to the sub. Neither move touches revenue or cost, because both were recorded when the work was done, not when the cash moved.

What this looks like on the statements

The same three entries, seen from the reports. The highlighted lines exist only because the accounts above exist.

Gross profit of 45,000 on 225,000 of earned revenue is the same 20 percent margin the estimate promised. If revenue were left at the 250,000 billed, gross profit would read 70,000 and the job would look better than the bid, which is exactly the number a surety learns not to believe.

The two retention lines are cumulative across every open job, which is why they are larger than the single job in the entries above. The 8,400 in underbillings comes from a different job that is behind on invoicing. A surety reads the two WIP lines together: underbillings that keep growing suggest revenue that may never be billed, and overbillings that keep growing suggest the contractor is living on the next job's cash. The generic chart shows neither line, so the surety asks for the spreadsheet instead.

What changes from a generic chart

Job Costing Implementation

Job Cost Structure

Each construction project should track costs in categories that match your chart of accounts:

Job Cost Categories:

1. Direct Labor: All labor directly working on the job
2. Direct Materials: Materials incorporated into the project
3. Subcontractors: External contractors performing work
4. Direct Equipment: Equipment rental specific to the job
5. Other Direct Costs: Permits, utilities, cleanup, etc.
6. Job Overhead: Site costs that exist only because of the job

Job Numbering System

Develop a consistent job numbering system:

Format Examples:

• Year-Sequential: 24-001, 24-002, 24-003
• Customer-Year: SMITH-24-001, ABC-24-002
• Type-Year-Sequential: RES-24-001 (Residential), COM-24-001 (Commercial)

Account Coding for Jobs

Method 1: Job Classes (QuickBooks) Use the same accounts for all jobs but assign job/customer classes:

• Account: 5001 (Direct Labor - Field Workers)
• Class: Job #24-001
• Result: Direct Labor costs tracked by job

Method 2: Job-Specific Accounts Create separate accounts for major jobs:

• 5001-001: Direct Labor - Job #24-001
• 5001-002: Direct Labor - Job #24-002
• 5101-001: Materials - Job #24-001

Method 3: Project Codes Use project/dimension codes in advanced systems:

• Account: 5001 (Direct Labor - Field Workers)
• Project: 24-001
• Department: Construction
• Cost Center: Residential

Equipment Management

Equipment Cost Allocation

Direct Job Charging: Charge actual usage to specific jobs

Dr. Job Cost - Equipment           $500
    Cr. Cash/Equipment Rental           $500

Overhead Allocation: Include equipment costs in overhead rates

Dr. Equipment Overhead             $2,000
    Cr. Accumulated Depreciation        $2,000

Dr. Job Cost - Overhead            $800
    Cr. Equipment Overhead             $800

Get started

Our Construction template starts a new chart with 65 accounts. It is a different layout from the accounts on this page, with its own names and numbers.

The optimizer reads your own chart and proposes changes for you to review. It does not compare your chart with the accounts on this page. Tag every job cost to a customer or project from the first invoice on and post Entry 3 on the last day of every month, and the books will agree with the WIP schedule.
