US GAAP Audit Readiness: A Controller's Practical Roadmap

Audit readiness is not a binder assembled shortly before the auditors arrive. It is the result of a finance function that can explain its balances, reproduce its support and show that important accounting activities are controlled. My US GAAP experience has included multi-entity controllership at Honeywell, intercompany accounting at NOV, the Mexico division of Forza Transportation and current fractional finance work for U.S. companies.

Start with GL and balance-sheet integrity

Every material balance should have an owner, a reconciliation method and support that can be reproduced. Old reconciling items, unexplained fixed assets, duplicate transactions and inconsistent master data are not merely cleanup issues; they affect management decisions and audit evidence.

Make the close repeatable

At Honeywell, SOPs for tax accruals and journal entries helped reduce month-end close time by 25%, while data mapping and vendor cleansing reduced reconciliation errors by 40%. Repeatability matters because an audit-ready process should produce reliable evidence every period, not only when someone knows an audit is coming.

Control intercompany before consolidation

Intercompany differences become more difficult to resolve after they reach the consolidation layer. At Honeywell, redesigned intercompany workflows contributed to a 30% faster close process. At NOV, the same discipline had to work across entities using JD Edwards and NetSuite before consolidation through HFM.

Document judgments and supporting evidence

US GAAP reporting requires more than correct arithmetic. Accruals, reserves, revenue treatment, classifications and other judgments need support that another qualified reviewer can follow. The exact accounting guidance depends on the transaction; the control objective is to make the conclusion traceable from source evidence to journal entry and financial statement.

Separate corporate reporting from local compliance

Cross-border finance often works in more than one framework at the same time. In Gulf Copper, reporting sent to the United States followed US GAAP while local accounting followed Mexican NIF. At ABB and Honeywell, the primary corporate environment was US GAAP while regional or internal policies also required IFRS knowledge. Good controllership keeps those requirements distinct instead of treating them as interchangeable.

Build the PBC package continuously

Bank support, debt schedules, reconciliations, fixed-asset records, intercompany support, policy documentation and control evidence are easier to maintain during the year than reconstruct at audit time. Audit readiness is therefore a monthly operating discipline: close, reconcile, explain, document and retain the evidence.
