Why a GAAP Conversion Specialist Costs Less Than You Think (And Less Than the Alternatives)

Before I walk through my pricing and process with prospects, the most common default I hear is some version of: ‘Can we just have our CFO handle this?’ Or: ‘We were thinking of putting this to Deloitte.’ Both are reasonable instincts. Here’s why they usually don’t play out the way people expect.

Option 1: Big 4 or Large Firm

If you go to a Big 4 firm for a GAAP conversion, you’re typically looking at fees that start at $150,000 to $250,000 for the same scope I’d price at $20,000 to $80,000 depending on complexity. For larger or more complex engagements, the Big 4 number goes higher still.

That’s not because Big 4 accountants are doing three times as much work. It’s because of how those firms are structured. You’ll have a partner who sells the engagement, a manager who runs it, two or three seniors doing the work, and an associate formatting documents. Each person bills at a different rate, and you’re paying for all of them, plus the firm’s overhead, office space, and their business development costs. Senior staff rate cards at Big 4 firms typically run $400 to $600 per hour or more.

There are scenarios where a larger firm might make sense: if your timeline is extremely compressed and you genuinely need a large team running multiple workstreams in parallel, or if the GAAP conversion is one piece of a full M&A advisory mandate where the same firm is handling the entire transaction. Even then, you’re often better served by bringing in a specialist for the accounting piece rather than paying transaction advisory rates across the board. For a focused single- or multi-entity conversion, you’re paying a significant premium for overhead that doesn’t make your conversion better.

Option 2: Hiring Someone In-House

The appeal is obvious: your own person, who knows your business, without an external fee. The problem is that a GAAP conversion is not an ongoing function; it’s a time-bounded technical project that requires specific knowledge most finance professionals don’t use day-to-day.

A finance director or controller who has been running FRS 102, HGB, or Norwegian GAAP for five years has not necessarily spent time working through ASC 606 revenue recognition, ASC 842 lease accounting, or the SEC’s requirements for foreign private issuers. Getting someone up to speed takes time they don’t have — and the errors you don’t catch the first time tend to surface at the worst possible moment: in diligence, or during your first audit.

If you’re hiring a US GAAP specialist into your European finance team, you’re looking at a salary of EUR 90,000 to 130,000 plus benefits and recruiting costs, for a role that will spend most of its time doing things that don’t require GAAP conversion expertise. And by the time that person understands your business and your accounting well enough to run the conversion, you’ve already missed your deadline.

I’ve worked alongside a number of in-house hires who were brought in specifically to ‘manage the GAAP conversion’ and then realized they still needed outside support. You end up paying both: the new hire and the specialist. That’s almost always more expensive than starting with the specialist.

Option 3: Assigning It to Your Controller

This one comes up when the company is trying to save money, and it almost always costs more in the end.

Your controller is managing your existing close process, your audit relationship, your statutory filings, and probably several other projects at the same time they’re being asked to run a GAAP conversion. The conversion gets pushed to nights and weekends, or it gets deprioritized every time something more urgent comes up. And because it’s being done by someone who doesn’t do this full-time, it takes longer than it should.

The real cost here isn’t the controller’s salary allocated to the project. It’s what they’re not doing while they’re working on this: the monthly close, the audit prep, the day-to-day. And if the conversion has errors that surface in diligence or during an audit, fixing them after the fact almost always costs more than getting it right the first time.

What You Actually Get With a Specialist

When you hire me for a GAAP conversion, you’re paying for someone who has done this specific work, for companies like yours, under similar time pressures, across dozens of engagements. I know where the meaningful differences are between FRS 102 and US GAAP. I know what PCAOB auditors look for in a revenue recognition memo. I know what a US investor’s accounting team is going to ask about your financial statements before they’ll sign off.

That experience means the work gets done faster, with fewer iterations, and with a lower risk of the errors that cause problems later. It also means your Controller can focus on the things only your Controller can do.

The Number That Actually Matters

The question isn’t whether a $20,000 to $80,000 engagement feels like a lot. The question is: what does it cost if you don’t get this right?

A deal that falls apart because US GAAP financials weren’t ready in time. An audit that drags on for months because the conversion work wasn’t documented properly. A fundraise that stalls because your investor’s accounting team found errors in your restatement and lost confidence in your financial reporting.

A properly scoped GAAP conversion by someone who does this work full-time is one of the better investments you can make in a transaction process.
