Technical Accounting Memos for Audits: What Auditors Expect

Written by FirmKey | Oct 16, 2026, 12:38:40 PM

When a company enters into a complex transaction, auditors want to see how management reached its accounting conclusion. A technical accounting memo is that record. For public companies, and for private companies heading into an audit, a sale, or a capital raise, well-prepared memos are a core part of audit readiness.

What is a technical accounting memo?

A technical accounting memo documents management's analysis and conclusion on how a transaction should be accounted for under U.S. GAAP, and where relevant, SEC reporting requirements. It shows the facts, the guidance applied, the judgments made, and the reasoning behind the final treatment.

What auditors expect

A strong memo does more than restate accounting guidance. It should:

  • Define the issue clearly and narrowly
  • Summarize the relevant facts, including contract terms
  • Analyze the authoritative guidance that applies
  • Document key judgments and assumptions
  • State a clear conclusion, including journal entry and disclosure impact

Common areas that need a memo

  • Revenue recognition
  • Stock-based compensation
  • Debt and equity transactions, including convertible instruments and warrants
  • Business combinations and asset acquisitions
  • Leases
  • Adoption of new accounting standards

Why it matters

Weak or missing documentation is one of the most common causes of audit delays. When the analysis isn't written down, auditors ask more questions, fieldwork stretches out, and adjustments show up late. For public companies, it can also raise the risk of SEC comments on periodic filings.

Well-prepared memos do the opposite: fewer follow-up questions, a smoother audit, and a defensible position if the treatment is ever challenged.

When to prepare one

The best time is when the transaction happens, not when auditors ask. Writing the memo while the facts are fresh makes the analysis stronger and gives you time to resolve questions before year-end. This matters even more ahead of a sale or capital raise, when buyers and investors will look closely at how complex items were handled.
