If you're evaluating GAAP conversion costs or the pricing of an audit readiness project, this page explains how I price my work, what drives that pricing, and how to work out whether my approach is the right fit before getting on a call.
(and how much it costs)
Most projects begin with a similar set of circumstances. A European tech or biotech company is moving into the US, preparing for a PCAOB audit, or dealing with an American investor’s reporting expectations for the first time.
The state of play usually looks like this:
In short, getting this right and documenting it clearly matters more than minimizing costs.
Clients have achieved up to a 50% reduction in advisory fees compared to larger accounting firms. Pricing is defined upfront. Anything outside the original scope is agreed upon separately before it begins.
The best part about working with Katrina was her ability to simplify complex accounting principles and make them understandable. Unlike other consultants, she took the time to tailor her advice to our specific needs and industry context.

I work with European companies navigating the accounting and reporting requirements that come with bringing in US investors. That typically means GAAP conversions, PCAOB audit readiness, investor-grade financial reporting, and the IPO accounting pricing questions that come into focus when a listing is on the horizon.
This isn’t a generalist advisory practice, and the scope is narrow on purpose. I offer a specialist service for a specific, technically demanding area: where European and US accounting frameworks meet, and where precision and documentation quality matter most.
In practice, that means conversion matrices for all relevant financial statement line items, technical accounting memos documenting and defending the positions taken, and a finance team that understands the basis for each conclusion once the work is complete.
Large advisory projects in this space tend to share a common set of structural problems. Work is distributed across multiple teams, which creates friction. Ownership of accounting positions is unclear, which creates delays. The finance team spends significant time managing the relationship rather than moving the work forward.
Reduction in advisory fees vs. larger accounting firms
Snowplow Analytics achieved a 50% reduction in advisory fees compared to larger accounting advisory firms on its GAAP conversion project.
When the work is done, your finance team should have more than a completed conversion. They should have documentation that holds up to scrutiny, accounting positions they can defend, and reporting processes they can run themselves.
Katrina was proactive and pragmatic in her approach, gaining a good understanding of our business and delivering the agreed documentation to underpin the financial statements and support the audit process. She was very helpful in guiding me through a complex and technically challenging project and I would definitely recommend her!

The model works best when both sides are prepared. That means having an internal contact who can own the pre-work where scope allows, clear access to the accounting records and policies that inform the conversion, and a realistic timeline that doesn’t shorten the documentation phase.
The more organized you are when you come in, the more of my time I can devote to high-complexity accounting work rather than information gathering. Both improve the quality of the output and keep the fee in check.
All work is priced on a fixed-fee, project basis. There’s no hourly or day-rate billing. The fee is defined at the outset, tied to a specific scope, and doesn’t increase unless that scope changes.
Hourly and day-rate billing makes sense for open-ended or capacity-based work, where the volume isn’t known in advance. When pricing a GAAP conversion or audit-readiness project, a fixed fee means the price reflects the outcome delivered, not the time required to deliver it.
Where the full scope of a project isn’t yet clear, I structure work in phases. An initial scoped phase establishes the accounting positions and priority areas before the full project begins. This allows both of us to move forward with confidence.
Katrina’s extensive understanding and knowledge of the subject, attention to detail and commitment to excellence were evident in every aspect of her work, ensuring the successful completion of our accounting project.

Five factors drive the cost of any project. Understanding them before the scoping call means that the conversation can focus on structure and timeline rather than fundamentals.
Number of legal entities and distinct GAAP frameworks involved in the conversion.
How much pre-work your team can own vs. what I handle directly.
Number and complexity of accounting positions requiring formal documentation.
Number of historical periods, urgency, and depth of audit readiness required.
How much liaison with auditors, lawyers and implementation teams is required.
The following scenarios describe real projects structured across three frameworks. They're not fixed packages. Each project is scoped individually, and these examples illustrate how spec, internal involvement, and complexity combine to shape the fee.
A UK-listed fintech entering the US market
A publicly listed UK fintech needed to understand the gaps between its existing IFRS framework and US GAAP before engaging with US investors. With an experienced internal finance team in place, the client handled the pre-work: documenting current accounting policies and the chart of accounts.
My scope covered surfacing the differences, co-developing the conversion approach, and delivering a prioritized roadmap. Outputs included a full GAAP Summit, recommended US GAAP policies, and a clear action plan for the conversion ahead. The high level of internal involvement kept the scope focused and the fee at the lower end of the range.
Project outcome
The company entered its US investor conversations with a clear understanding of its accounting position and a documented plan for the full conversion.
A Norwegian biotech preparing for a PCAOB audit and US listing
A Norwegian biotech company required a full conversion from Norwegian GAAP to IFRS in preparation for a PCAOB audit and potential US listing.
This was a full-service project: the complete IFRS conversion matrix across all financial statement line items, a half-day GAAP Summit workshop with the finance team, and four technical accounting memos covering a restructuring, a patent acquisition (business vs. asset assessment), a debt-to-equity conversion, and R&D capitalization policy. I owned the full scope of the work, which is reflected in the fee.
Project outcome
The company completed its IFRS conversion with fully documented accounting positions, audit-ready financials, and a finance team that understood the technical basis for each conclusion.
A pan-European streaming platform preparing for US GAAP reporting
A UK-headquartered global streaming platform with subsidiaries across Germany, Turkey, the Netherlands, Belgium, and the US engaged me following a significant US investment. The complexity spanned six entities across six accounting frameworks.
Across two phases, the work covered the full GAAP conversion matrix across all jurisdictions, a collaborative GAAP Summit, and five technical accounting memos covering the overall conversion approach, revenue recognition, content asset accounting, share-based compensation, and acquisition accounting.
Project outcome
The platform delivered its first US GAAP financials to its new investor with consistent, documented positions across all six jurisdictions and a reporting framework it could maintain internally going forward.
Katrina's tried and tested methodology in executing GAAP translation work allowed us to collectively quickly identify where the work needed to be focused. Katrina's ability to take individual, nuanced accounting problems and simplify their translation was her greatest USP.

Before we speak, it’s worth knowing where your project is likely to land.
My pricing calculator asks the questions that drive the fee: the number of entities, internal capacity, technical memo requirements, and timeline. It returns a working cost estimate in about two minutes, and you’ll need to enter your email address to receive your results.
People who use the calculator before the call arrive with a realistic sense of the cost and a clearer picture of their own scope, which makes the conversation more focused for both of us.
Each project typically starts with a Discovery Call to explore your business, goals, pain points, and project requirements. This helps me fully understand what you’re looking to achieve.
Once I’ve reviewed your needs, we’ll move on to a Proposal Call, where I’ll walk you through my recommended strategy, project scope, timeline options, and pricing.
The calculator provides you with a helpful starting estimate although final pricing may differ based on the details uncovered during our conversations and the specific requirements of your project.
Estimate your project cost before the scoping call. It takes around two minutes.
A 30-minute conversation about fit, structure, and timeline. Best done after the calculator.
