What Is Billings in Excess of Costs? Contractor Guide 2026

Open the balance sheet of almost any Inland Empire general contractor using the percentage of completion method and you will find a line item many owners cannot fully explain: billings in excess of costs. On the IRS’s own sample contractor balance sheet, the account — formally Billings in Excess of Costs and Estimated Earnings — sits among current liabilities. It is not an error and not a gimmick. It is the record of progress billings that have run ahead of the work your crews have completed.

Billings in excess of costs is a balance-sheet liability a contractor records when progress billings have outrun the work actually completed under the percentage of completion method. It represents an obligation to deliver work in the future — similar in concept to deferred revenue. The account label alone does not determine taxable income or deductions; those depend on the applicable contract accounting method.

Adham works with general contractors, electricians, and specialty subs from Moreno Valley to Temecula on the job files, WIP schedules, and percentage-of-completion entries behind these balances. If your over- and under-billing accounts have stopped agreeing with the job files, our construction job costing services rebuild the trail contract by contract. Below: what the account means, how the entries work, and how the same balance is treated differently on your books and your return.

This guide focuses on journal entries and month-end WIP reconciliation. For the underlying balance-sheet meaning and tax-method cautions, see our billings-in-excess overview.

Key Takeaways

• Billings in excess of costs is a liability recorded when a progress invoice exceeds the revenue earned under the percentage of completion method — an obligation to deliver work later, similar in concept to customer deposits and deferred revenue.
• Its mirror account, costs and estimated earnings in excess of billings, is an asset — also called unbilled receivables or unbilled work in progress.
• The IRS construction audit guide treats the two accounts as distinct: they are not netted or offset against each other, and both should be present on the balance sheet.
• In the classic entry, a $25,000 invoice issued for $20,000 of completed work debits accounts receivable $25,000, credits revenue $20,000, and credits the overbilling account $5,000.
• At year end, each open contract’s net balance — costs incurred to date plus estimated earnings, minus total bills rendered — is sorted: credit balances form the liability, debit balances the asset.
• Book overbilling and underbilling balances do not automatically become tax income and deductions. Reconcile them using the permissible method for the contract.

What Billings in Excess of Costs Means on a Contractor’s Balance Sheet

The plain-English definition

Commercial credit-training materials used by lenders put it directly: billings in excess of cost and profits is “the amount of invoice to a client that exceeds the actual work performed under a specific contract using the percentage of completion method of accounting.” When the invoice exceeds the value of work performed at that point, the difference reflects an obligation to deliver — or complete — a specific amount of product in the future, similar in concept to customer deposits and deferred revenue. Naming varies: the IRS guide calls it Billings in Excess of Costs and Estimated Earnings; the credit-training materials call it Billings in Excess of Cost and Profits. Same idea, different label.

Why the account exists at all

Percentage of completion is a computation, not a byproduct of daily bookkeeping. The IRS guide notes that the completion measure — costs incurred divided by total estimated costs — “is a computation not made through the day-to-day book recording procedures,” and there is no general ledger account for total estimated contract costs. To account for the difference between revenue recognized under the method and the amounts billed, two balance sheet accounts are created: Costs and Estimated Earnings in Excess of Billings (asset) and Billings in Excess of Costs and Estimated Earnings (liability).

How it shows up in practice

In the IRS guide’s sample contractor balance sheet, the account sits in current liabilities at $5,666, alongside accounts payable and accrued liabilities (IRS Construction Industry Audit Technique Guide). The guide footnotes that the account should reconcile to its Contracts in Progress schedule — a tie-out many contractors skip until a lender, surety, or auditor asks for it.

Recording the Balance: Journal Entries and the WIP Connection

The mechanics are easiest to see in both directions:

Scenario	Debits	Credits
Invoice of $25,000 issued for $20,000 of work completed	Accounts Receivable $25,000	Revenue $20,000; Billings in Excess of Cost and Profits $5,000
Work completed worth $25,000; invoices to date $20,000	Accounts Receivable $20,000; Costs and Profits in Excess of Billings $5,000	Revenue $25,000

(Entries per the contractor accounting Q&A used in commercial credit training.)

In the first row, the $5,000 credit is the overbilling — money billed ahead of earned revenue. In the second row, the mirror account appears; it is also referred to as unbilled receivables or unbilled work in progress.

The IRS guide’s example contract

The guide illustrates the method with a long-term contract carrying a $3,000,000 estimated contract price against $2,000,000 of estimated contract costs (IRS Construction Industry Audit Technique Guide). Because the completion percentage depends on costs incurred divided by total estimated costs — and estimates live outside the general ledger — the two balance sheet accounts are what force the books and the job-level computation to agree.

The year-end sort, step by step

1. For each contract in progress at year end, compute a net balance: total cost incurred to date plus estimated earnings (on the percentage of completion method), reduced by the total amount of bills rendered.
2. Read the sign: a debit balance means total costs and estimated earnings exceed billings; a credit balance means billings exceed costs and estimated earnings.
3. Add together all contracts with debit balances and show the total as an asset on the balance sheet.
4. Aggregate the credit balances into the billings in excess liability — leaving the two accounts un-netted, per the IRS guide.
5. Tie the resulting liability to the contracts-in-progress schedule before closing the year.

If the balance exists but cannot be traced to a contract file, that is usually a posting-discipline gap — one worth closing with professional bookkeeping help before a lender or surety asks for the schedule.

Billing ahead of costs is good cash flow — until your WIP schedule and general ledger stop agreeing. If your balance sheet shows a billings-in-excess balance you cannot trace to a job, Adham will walk your contracts, entries, and job-cost reports and show you exactly where the disconnect starts.

Why Contractors Bill Ahead of Costs — and When It Backfires

From the contractor’s side, billing ahead is usually the preferred position: if the client pays the invoice, it provides cash to pay for the project as it unfolds. For a subcontractor stretching payroll and materials across Riverside and Corona jobs, that spread between billings and earned revenue is often what funds the next draw.

Two limits come straight from the source materials:

• Both accounts can coexist across jobs — never on one job. With several projects underway at once, it is very common to see both billings in excess and costs in excess on one balance sheet; a contractor with a single job will show one or the other, but not both, for that job.
• The balances assume a going concern. In a liquidation or work-out scenario, the value of billings in excess and costs in excess can be questioned — as can the value of many other assets on the balance sheet.

As jobs come to completion, both accounts are eliminated — the liability unwinds as the work catches up to the billing, and the asset unwinds as the billing catches up to the work.

GAAP vs. Tax Treatment on Your Return

The same account is treated differently on financial statements than on the tax side:

Account	GAAP financial statements	Tax treatment
Billings in excess of costs (and estimated earnings)	Balance sheet liability	Apply the applicable tax accounting method; not automatically taxable because it is an overbilling
Costs in excess of billings (and estimated earnings)	Balance sheet asset	Apply the applicable deduction and timing rules; not automatically deductible because it is an underbilling

The book balances show the relationship between earned revenue and progress billing. Tax recognition is a separate method question: section 460 generally requires percentage-of-completion treatment for long-term contracts, subject to construction-contract exceptions. See IRS guidance on section 460.

Where these balances land on your business tax return — and how they fit the rest of your tax preparation plan — is worth settling before year-end close, not after.

That gap is one more reason the account needs to reconcile to the contracts-in-progress schedule. If your WIP schedule and general ledger tell different stories, construction bookkeeping support should rebuild the schedule from the job files — not plug the difference with a journal entry.

Frequently Asked Questions

What is billings in excess of costs?

It is the liability recorded when a contractor’s progress invoice exceeds the actual work performed under a specific contract on the percentage of completion method. The excess represents an obligation to deliver or complete work in the future, similar in concept to customer deposits and deferred revenue.

Is billings in excess of costs a debit or a credit?

At year end, the IRS guide computes a net balance per contract: a credit when billings exceed costs and estimated earnings — that credit forms the liability — and a debit when costs and estimated earnings exceed billings, which forms the asset. During the year, the overbilling account is credited by entries like the example above.

Can billings in excess of costs and costs in excess of billings appear together?

Yes — across multiple jobs it is very common to see both, since some contracts are overbilled and others underbilled. For a single job, only one of the two can exist. The IRS guide directs that the accounts not be netted or offset; both should appear on the balance sheet.

How is billings in excess of costs treated on a tax return?

The balance alone does not determine the return treatment. Identify the permissible method for the contract and reconcile book revenue and costs to tax amounts. IRS guidance on section 460 describes the general rule and construction-contract exceptions.

Is billings in excess of costs the same as deferred revenue?

Similar in concept, not identical in context. This account arises specifically when billings outrun the earned percentage of a contract in progress, while deferred revenue is the broader obligation concept it resembles. Both represent an obligation to deliver work in the future.

How do you reconcile billings in excess of costs?

The IRS guide footnotes that the account should reconcile to its Contracts in Progress schedule. In practice, recompute each contract’s net balance at year end — total cost incurred to date plus estimated earnings, reduced by total bills rendered — and confirm credit balances land in the liability and debit balances in the asset.

What happens to the account when the job is complete?

As jobs come to completion, both accounts are eliminated — the balances unwind as the work catches up to the billings. That unwind assumes a going concern, which is why the balances can be questioned in a liquidation scenario.
