You’ve just closed a deal that brings US reporting into your finance team

A fundraise with US investors, an acquisition by a US company, or a PCAOB audit ahead of a US listing.

  • You have a skilled internal finance team, but it's not structured for the cross-border complexity involved.
  • You're managing the process with limited capacity to coordinate the various tasks involved.
  • The accounting positions established during this period will be reviewed by auditors, investors, or regulators.

How I help you bridge the GA(A)P

Cross-border accounting doesn't have to be confusing or expensive. I help finance teams on both sides of the Atlantic get practical answers on cross-border accounting and reporting.

When you work with me, you get

Clarity on the differences that matter

I map US GAAP, IFRS and your local GAAP side by side in a GAAP matrix, ranked by what changes your numbers, so you know where to spend your team's time.

Advice that fits how you operate

I work from your trial balances, contracts and systems, so each accounting position fits how your business actually runs.

Right-sized support

One person, a fixed fee and a scope that matches what you need, with your team taking on as much of the work as it wants.

A stronger finance team

I explain the reasoning as we go, so your team can maintain the new standards, policies and processes after the project.

Planned around your deal

Every project works back from the date that matters, whether that's an IPO, an acquisition or a US fundraise.

What clients say

“In preparation for our first US GAAP group audit at Taktile, our biggest challenge was to identify all areas in our books that need adjustments, especially the ones that go beyond the obvious. [...] Together with her, we identified the necessary adjustments on group and local entity level, which gave us a clear way to become audit-ready.”
Sven Zeidler, Director Finance, Taktile
“Following investment from a US based listed business, we had to rapidly translate our reporting from UK to US GAAP. [...] Katrina's tried and tested methodology in executing GAAP translation work allowed us to collectively quickly identify where the work needed to be focused.”
Ben Williamson, Group Finance & Commercial Director, Totally Wicked
“Referred to us by our auditors at PwC, she worked seamlessly with both our audit and legal teams to ensure timely and accurate completion of the ASC 805 memo, SEC pro forma financial statements, and disclosures [...]”
Terry Coelho, EVP & CFO, HOOKIPA Pharma
“Her approach to every topic was quite tailored to our business which meant that she only took us through what was of benefit to our company. [...] My team and I now have the knowledge and confidence we need to report under the US GAAP.”
Tim Kamombo, FD, PensionBee
“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 to support the audit process.”
Tom Morgan, Head of Financial Control, Snowplow
“After the discovery section of the project Katrina clearly laid out her findings in a memo that was easy to understand and did a follow up call to answer all the questions I had. [...] The memo she produced now forms the basis of our US GAAP accounting policy.”
Eoin Weeks, Finance Director, Wagestream
