Your weekly go-to guide to transform your finance function into a strategic powerhouse.

Welcome CFO Techstack Community 👋,


This week we're exploring a responsibility that rarely appears in a CFO job description. Drawing on insights from PawaPay CFO Aaron Markowitz-Shulman, we look at why the best CFOs become trusted thinking partners.


We're also looking inside RSGx's finance tech stack, with CFO Andy Colalillo sharing the tools behind a $500M+ business. Harriet also shares her advice for first-time in-house finance hires and what to prioritise in the first 90 days.

 

FEATURED ARTICLE

The responsibility no CFO job description mentions

Among the discussions at July's FLAC workshop was one about a responsibility that rarely appears in a CFO's job description. During his conversation with David Tuck, Aaron Markowitz-Shulman, CFO of PawaPay, shared an observation that stayed with me long after the conversation had moved on.

 

"Being a founder is an incredibly lonely job," he said. "Your board wants results. Your investors want growth. Your staff look to you for certainty. Very few people are able to tell you honestly when something isn't working."

His point was that founder loneliness creates a gap inside every organisation. There are very few people with enough visibility across the business, and enough trust, to challenge a founder's thinking honestly. Aaron believes that's one of the most valuable roles a CFO can play.

 

The honest broker

Finance occupies a unique position within an organisation. It sees the business through the numbers, but it also understands the decisions behind them. As Aaron described it, the CFO can become the "honest broker". Someone who is close enough to understand what's happening, but independent enough to say the things others might hesitate to say.

 

Sometimes those conversations are uncomfortable. "That decision we made last quarter was really bad. You know this is not working, right?" Or, "This department isn't really going well." Those aren't conversations designed to catch someone out. They're conversations that help a business recognise when reality has moved on from the assumptions that shaped an earlier decision.

 

Challenge without criticism

Aaron was careful to distinguish challenge from criticism. He spoke about "building that relationship where you can be a kind of thinking partner with somebody else in the business". The objective isn't to have all the answers. It's to create enough trust that difficult questions can be asked, assumptions can be tested and better decisions can follow.

 

That relationship matters because founders rarely have many places where they can think out loud. Boards expect results. Teams look for certainty. Honest challenge, delivered by someone who understands both the business and the numbers, becomes another form of support rather than opposition.

 

A different kind of contribution

That feels like one of the least discussed responsibilities of a CFO. Financial control, forecasting and reporting will always matter, but they're not the end of the story. They give finance the credibility to contribute when the conversation moves beyond what happened and turns to what should happen next.

 

Aaron finished with a line that captured the idea perfectly. The best CFOs don't simply report performance or safeguard the numbers. They become "trusted thinking partners rather than scorekeepers."

    First 90 days as an In-house Finance Hire? Don’t Rush the Handover

     

    Readers question:

    Finance at our company is still mostly handled by our external accountants. I have just joined as the first in-house finance hire. What should I prioritise in the first 90 days?

     

    Harriet’s answer:

    First things first, resist the urge to cut the external accountants loose. When you’re the first in-house finance hire, it’s tempting to prove the business no longer needs them. Don’t. A thorough handover is worth its weight in gold.

     

    Keep the accountants in the loop, on purpose

    Budget for an overlap period, ideally the full 90 days. It gives the external accountants time to walk you through the detail instead of leaving you to piece it together yourself. It will cost a little more, but it’s worth every penny.

     

    The handover doesn’t have to end after 90 days either. Keeping the same accountants involved for other services means you retain the knowledge they’ve built up about the business. That might be year-end accounts, the tax return or simply having someone to call when an unfamiliar issue crops up.

    Treat the systems as a blank canvas

    The setup you’ve inherited was probably built for compliance. That’s not a criticism of the accountants. It’s simply the job they were there to do. Now that you’re in-house, the expectations are different. Start from first principles. Automate the bookkeeping. Build a robust month-end process. Get the foundations right before introducing anything more ambitious. Walk before you run.


    It’s common in early-stage businesses. An outsourced finance function will often have an accounting system and a data ingestion tool such as Dext, and that’s usually enough at that stage. As the business grows, the finance function needs more capability. That might mean introducing tools such as Mayday to support the month-end close, ApprovalMax to strengthen finance controls, and more robust accounts payable.

    That’s why it’s worth making sure those foundations can support the next stage of growth. A chart of accounts should be built around how the business wants to understand its performance, not just how it needs to file. Do that now and you’ll save yourself months of rework later.


    Get a handle on cashflow immediately

    The moment you’re in-house, expectations change. Leadership will expect answers on cash much sooner than they did when finance was outsourced. Even a simple weekly cashflow summary in your first few weeks shows the business that you’re on top of the numbers while you build the rest of the finance function.
