Preparing the trial balance before audit fieldwork

A clean trial balance does not guarantee a quiet audit, but a messy one almost guarantees delays. When our fieldwork begins, the first documents we ask for are the locked trial balance, the mapping to financial statement line items, and the reconciling schedules behind cash, receivables, inventory, and accruals.

Lock a cut-off date

Agree the ledger close date with your closing checklist owners. Post-close journals should be listed separately so auditors can see what changed after the lock. Unlabelled “cleanup” journals posted during fieldwork create rework for both sides.

Reconcile before we arrive

Bank reconciliations should tie to the general ledger, not only to the bank portal balance. Aged receivables should explain credits and amounts past due beyond your normal terms. Inventory quantities should match the count sheets you will use for observation.

Document estimates in plain language

For allowance for doubtful accounts, inventory obsolescence, and useful lives on property, write a short memo describing the method and the inputs. Auditors will still test the calculation, but a clear memo prevents circular questioning in week one.

Related parties and unusual items

List related-party balances and the nature of each relationship. Flag non-recurring gains, insurance recoveries, and large year-end accruals. Surprises discovered late in fieldwork are expensive in calendar days even when they are legitimate.

If you want a pre-engagement readiness review of your schedules, ask about a short agreed-upon procedures visit before the statutory audit window.
