How Auditors Review Prepayment Schedules (and What They Look For)
Understand what external auditors examine during prepayment schedule testing, so you can prepare your documentation and avoid surprises.
External auditors test prepayment schedules as part of their balance sheet audit. Their goal is to confirm that the prepaid asset balance is not materially misstated — meaning every item on the schedule is real, properly valued, and correctly classified.
Existence and Completeness
Auditors will select a sample of items from your prepayment schedule and trace them back to the original invoice or contract. They want to see that every item on the schedule corresponds to a real payment. They may also select items from expense accounts and check whether any should have been treated as prepayments but were not.
Accuracy of Amortization
For each sampled item, auditors will recalculate the amortization. They check the start date, end date, original amount, and monthly expense figure. If you use straight-line monthly amortization, the recalculation is straightforward. If you use custom schedules, they will want to see the basis for the allocation.
Reconciliation to the GL
The total of all items on your prepayment schedule should agree to the balance in the prepaid asset account on the general ledger. Auditors will ask for this reconciliation. If there is a difference, you will need to explain it. Unexplained differences are audit findings.
The single most common audit issue with prepayments is a difference between the schedule total and the GL balance. Keeping these in sync throughout the year — not just at year-end — eliminates this problem entirely.
Classification and Disclosure
Auditors will check that prepaid amounts are correctly classified as current or non-current. They also verify that material prepaid balances are disclosed in the notes to the financial statements as required by the applicable accounting framework.
Adjustments and Write-Offs
If any prepayments were adjusted during the year — partial refunds, early terminations, write-offs — auditors will want to see documentation supporting the adjustment. This includes the reason, the approval, and the journal entry. An adjustment without a documented reason is a control weakness.
How to Prepare
- Maintain a detailed schedule that ties to the GL every month, not just at year-end
- Keep original invoices or contracts accessible for every prepayment
- Document the reason for every adjustment, termination, or write-off
- Ensure your amortization calculations are transparent and reproducible
- Reconcile the schedule to the GL before the auditors arrive
