What is the difference between 'unbilled receivables' and 'retention' in construction accounting, and how should each be audited?

• A. Unbilled receivables are current liabilities; retention is asset; audit by vendor payment tests.
• B. Unbilled receivables are earned revenue not yet billed (asset); retention is a holdback payable to subcontractors (liability); audit by contract review, confirmations with customers/subcontractors, and testing subsequent billings/releases.
• C. Unbilled receivables are cash reserves; retention is asset; audit by cash disbursement tests.
• D. Unbilled receivables are revenue recognized; retention is cash received; audit by revenue tests.

Answer: (B)

In construction accounting, unbilled receivables are assets that arise when revenue has been earned by completing work but has not yet been billed to the customer. This reflects the timing difference between recognizing revenue and issuing the invoice, and the balance should be supported by project progress, milestones, and contract terms.

Retention, on the other hand, is a liability—a holdback of a portion of each progress payment that the owner or contractor keeps to ensure completion and quality. It becomes payable to subcontractors only after meeting release conditions or milestones.

Auditing unbilled receivables focuses on verifying that revenue has actually been earned and properly recognized, even though billed later. This involves reviewing contract terms and project progress, change orders, and the basis for recognizing revenue; confirming with customers when feasible to validate the amount and timing; testing that the unbilled balance aligns with subsequent billings and releases; performing cutoff and aging tests to ensure amounts are not overstated or understated and that collection risk is appropriately considered.

Auditing retention concentrates on the liability side and ensuring proper accounting for holdbacks. This includes reviewing contract provisions for retention, confirming balances with subcontractors or owners, testing the proper calculation of holdbacks, and examining releases or reductions of retention against milestone completions or final payment. It also involves verifying that retention is correctly classified as a current liability and that the releases are reflected in subsequent payments or final settlements.
