What does technical accounting advisory actually cover?

Most accounting is routine. A minority of it is not, and that minority is where companies get hurt. A new revenue stream does not map cleanly to any example in the standard. A financing round comes with warrants and a conversion feature nobody knows how to classify. You sign a lease with a purchase option and a variable payment tied to usage. Each of these has a right answer under the standards, but finding it takes research, judgment, and the discipline to write down why.

That is what US GAAP and IFRS advisory delivers. We take the transaction or the reporting question you are stuck on, work it against the actual guidance, and give you a documented position you can book and defend. The output is rarely a one-line answer. It is a technical memo that states the facts, walks the standard, weighs the alternatives, and lands on a conclusion with the citations to back it.

The projects that land on our desk cluster into a handful of themes: revenue recognition, lease accounting, converting between frameworks, preparing financial statements from the ground up, accounting for complex or one-off transactions, and getting a set of books ready for an IPO or a first audit. The common thread is that a wrong call is expensive to unwind later, and a documented right call saves you an argument with your auditor.

A technical accounting memo is not paperwork. It is the argument your auditor tests line by line, and the record that proves the judgment was made on purpose rather than by accident. We write it to win that test.

When do you actually need technical accounting help?

You do not call for advice on routine entries. You call when the standard stops giving obvious answers and the stakes get real. A few moments send companies looking for technical accounting advisory:

  • You changed how you make money. A new pricing model, a bundled offering, a usage-based tier, or a channel partner arrangement can rewrite how and when you recognize revenue. Getting ASC 606 or IFRS 15 wrong here distorts every metric investors watch.
  • You signed something complicated. Convertible notes, SAFEs, earnouts, warrants, embedded derivatives, and business combinations all carry accounting that is easy to get wrong and painful to restate.
  • Your reporting framework has to change. A new parent, a cross-border deal, or a lender covenant can force an IFRS to US GAAP conversion, or the reverse, on a deadline.
  • You are heading into an audit or an IPO. First-time audits and public-company readiness surface accounting questions that never mattered while you were small and private.

The pattern is always the same. The cost of getting it right up front is a memo and some hours. The cost of getting it wrong is a restatement, a delayed close, or a diligence process that stalls while everyone argues about a number. We would rather you spend the small amount early.

US GAAP vs IFRS: how the frameworks split on revenue and leases

The two frameworks converged on the big principles but still differ in ways that change your numbers. Revenue and leases are where clients feel it most. Here is how the same question lands under each standard.

US GAAP IFRS
Revenue standard ASC 606, with detailed industry-specific implementation guidance IFRS 15, built on the same 5-step model but lighter on prescriptive examples
Revenue judgment More bright lines and codified interpretations to follow More reliance on principles, so more documented judgment is expected
Lease standard ASC 842 IFRS 16
Lessee model Keeps a dual model: finance and operating leases stay distinct in the income statement Single model: nearly all leases sit on the balance sheet and run through depreciation and interest
Practical effect Operating leases show a straight-line expense Front-loaded expense on most leases, which changes EBITDA and covenant math

How a technical accounting engagement runs

Every engagement follows the same disciplined path, so you know what you are getting and when. No open-ended research bills.

  1. 01

    Frame the question

    We nail down the exact transaction, the facts that matter, the framework in play, and what decision the answer has to support. A sharp question is half the work.

  2. 02

    Gather the facts

    We read the contracts, term sheets, and existing entries, and we ask the questions that change the accounting before we reach a view.

  3. 03

    Research the standard

    We work the issue against ASC or IFRS guidance, relevant interpretations, and the alternatives, and we test how each position holds up.

  4. 04

    Draft the position

    We write a technical memo that states the facts, walks the analysis, and lands on a conclusion with citations your auditor can follow.

  5. 05

    Book and present

    We translate the conclusion into journal entries, disclosures, and, where needed, the financial statement presentation, so the answer actually hits your books.

  6. 06

    Support the audit

    We stand behind the memo with your auditor, answer follow-ups, and adjust for any facts that surface during fieldwork.

What you get, and how long it takes

The core deliverable is a technical accounting memo: a document that states the facts, applies the standard, considers the alternatives, and reaches a conclusion your auditor can accept. Depending on the engagement, you also get the journal entries, the disclosure language, restated or newly prepared financial statements, or a conversion workbook that reconciles every material difference between the two frameworks.

Timing depends on the question. A focused revenue or lease position on a single contract can take days to a couple of weeks. A full IFRS to US GAAP conversion or a set of IPO-ready financials runs longer, because we have to work through every account, document each difference, and build the support an auditor and, eventually, a regulator will test. We scope the timeline before we start, and we flag anything that would move it as soon as we see it, so a diligence deadline or an audit date does not catch you short.

What actually drives the cost

We scope each engagement and quote before we start, so you are not signing up for an open meter. The number moves on real factors, not guesswork:

How complex the question is

A clean single-contract revenue view costs far less than a business combination or a multi-element financing instrument that needs several standards read together.

One framework or two

A conversion or a dual-reporting question means working the same facts through both US GAAP and IFRS, which is more effort than a single-framework opinion.

The state of your records

If your contracts, ledgers, and prior entries are clean and organized, we move faster. If we have to reconstruct history first, that is where the hours go.

Depth of documentation needed

A memo for internal use is lighter than one built to survive audit scrutiny or IPO-level review, and the audience sets the rigor.

Why run your GAAP and IFRS work with FinAudit CPA

Many advisers know one framework well and treat the other as a footnote. We work fluently in both. That matters the moment your reporting has to cross a border, satisfy a new parent, or serve investors who read statements in a different standard. A single team handles the conversion or the dual-reporting question, so you are not paying two specialists to hand your file back and forth and hope their conclusions agree.

There is a second advantage that is easy to underrate. We are a licensed CPA firm that also examines controls and audits financial statements, so when we take a technical position, we already see how it moves through your billing, your close, and your reporting. A revenue conclusion is not an abstract citation to us. It is entries that have to reconcile, disclosures that have to tie, and a control environment that has to produce the number every period. The same team that reads the standard understands the machinery behind your books, and that keeps a clever memo from becoming an operational headache later.

Pair your technical accounting work with

  • Quality of Earnings, when a transaction or a new revenue model needs to hold up under buyer or investor diligence
  • Business Combination Accounting, when an acquisition brings purchase accounting, fair value, and goodwill questions
  • Statutory Audit & Review, when the positions we document have to carry through to an independent opinion
  • IPO and audit readiness support, when you need a full set of books that a public-market process will test

US GAAP is the accounting framework used by US companies and set by the FASB. IFRS is used across much of the rest of the world and set by the IASB. GAAP tends to be more rules-based with detailed guidance, while IFRS leans on principles and expects more documented judgment. The two agree on many outcomes but differ on specifics like lease expense, inventory methods, and how some financial instruments are classified.

It is specialist help applying accounting standards to transactions or reporting questions that are not routine. We research the issue against US GAAP or IFRS, weigh the alternatives, and write a documented position you can book and defend. Typical topics include revenue recognition, leases, complex financing instruments, and business combinations, where a wrong call is costly to unwind and a well-supported memo saves an argument with your auditor.

Yes, in both directions. We work through every material account, document each difference between the frameworks, prepare the adjusted statements, and build a conversion workbook that reconciles the two. We often do this when a company gains a new parent, closes a cross-border deal, or faces a lender or investor that reports in the other standard. Because we work in both frameworks, one team owns the whole conversion.

We apply the same 5-step model both standards share: identify the contract, the performance obligations, the transaction price, allocate it, and recognize revenue as obligations are satisfied. The judgment lives in the details of your contracts, such as bundling, variable consideration, and timing. We document how your specific arrangements map to the standard so the revenue you report can withstand audit and investor scrutiny.

Both. We can resolve a single technical question, or we can prepare a full set of financial statements from your ledgers, including the notes and disclosures. This is common for companies heading into a first audit or an IPO, where the statements have to meet a standard they never had to meet as a small private business. We build them to be tested, not just to look complete.

Yes. We surface the accounting questions that a first audit or a public offering will raise, resolve them with documented positions, clean up historical entries, and prepare statements and support that an auditor and a regulator will examine. Doing this early keeps the formal process from stalling on issues that are cheaper to fix before the deadline than during it.

A licensed CPA firm signs opinions and examines controls, so we see how a technical position moves through your billing, close, and reporting rather than treating it as theory. That connection between the standard and the machinery behind your books keeps a clever conclusion from becoming an operational problem. It also means the memo we write is built to face the same scrutiny an auditor applies.
