The audit landscape is changing. Firms once tethered to desktop tools are assembling nimble ecosystems around cloud platforms, open APIs, and AI.

To understand how this transformation is unfolding on the ground, we brought together:

At Trullion, we see first-hand how firms are re-shaping their audit stacks around automation and AI – and we wanted to hear how leaders are making those decisions in practice. Here are the highlights to our discussion (you can also watch the full webinar on-demand, at any time).

1. How firms decide what to buy

At Whitley Penn, the team measures every new tool against three pillars: efficiency, quality, revenue. If a product delivers on two of the three, it’s worth a serious look:

  • Efficiency: Cut manual work, free staff from endless data entry, reduce hours per engagement
  • Quality: Strengthen audit outcomes, reduce risk, enhance client experience
  • Revenue: unlock new services or expand into new client segments 

The approach was crafted by an innovation group made up of team members from different practices and offices, ensuring a broad perspective. It’s a philosophy shared by Clark Schaefer Hackett’s David Rich. “You really need that cross-section across the firm of people who have exposure to things we’re not as familiar with… Maybe a tool isn’t as applicable to me, but someone in our government practice sees a huge use case for it,” he noted.

These groups often become champions of the new software – early adopters who drive rollout, help train new users, and build momentum.

David added two more pillars he finds especially important: UI/UX and client experience. Design is the interface between the client and the firm. “That needs to be top-notch. Ultimately, it can become part of the face of the firm,” he said. 

Another non-negotiable: usage metrics. Andy explained that this helps separate vendor promises from reality.

How do you allow me to track usage? Do you have a dashboard? Do you give me weekly reports, monthly reports? Tech needs to have a way to track that user interaction.

Vendors can claim big efficiency or adoption gains, but only concrete usage data shows whether a tool is truly delivering the value it promised.

2. Adoption is the difficult part

Getting people to use new software, every day, often feels like an uphill climb. Our panelists agreed that adoption is most successful when the tool addresses pain points.

One of the most important things for adoption is whether or not that tool solves a real problem that our firm users are experiencing. If it’s painful for them every day, they’re going to start using that tool right away.

At Clark Schaefer Hackett, teams review usage metrics every two weeks and feed insights back to vendors.  “When our users are seeing their feedback actually being incorporated into the product, that boosts adoption,” David said. The feedback loop is paying off: They’ve achieved ~75% daily active users and ~90% monthly on new tools.

Andy added that communication is just as important as functionality, with frequent, clear, and repetitive messaging.

That’s one of the biggest lessons I’ve learned over rolling out different softwares. You have to over-communicate with people – emails multiple times a week, newsletters, company announcements, short videos. You have to get to the point where you’re the walking poster for this product.

Adoption isn’t a one‑time push. It’s an ongoing campaign. Pilot with champions, monitor usage, and keep feedback loops active.

3. What “modern” actually means

When the panelists talked about “modern” audit software, four qualities came up consistently:

  • Cloud‑based delivery: Desktop software has hit its ceiling. Cloud enables access anywhere, smoother client exchanges, and faster vendor updates.
  • Open APIs: The future is an ecosystem of connected, best-in-breed tools. APIs make integrations possible.
  • Collaborative partners: Firms aren’t just looking for new software. They’re looking for partners with an innovation mindset who will continuously listen, train, and adapt.
Think of modern technology providers as an extension of your own team. Who’s on Customer Success? Who’s running your training? The world is changing quickly with AI. What does their roadmap look like? Make sure it’s strong, make sure they’re delivering on their promises.

Andy stressed that shipping velocity is non-negotiable: if you’re going months without updates, you’re falling behind. David added that he evaluates vendors by how their product and development teams show up in meetings. Are they receptive, resourced, and excited to implement feedback? 

And then there’s AI. Andy visualized the firm’s stack in three layers: 

  • Core audit platforms: The foundation consists of engagement management systems, methodology tools, and research databases. These platforms are deeply embedded in firm processes and change slowly, given their impact on compliance and consistency.
  • Analytics and visualization: The middle layer is tools like Excel add-ins, Power BI, and data analytics solutions that help teams explore trends and deliver insights. This layer evolves at a moderate pace, driven by efficiency gains and client reporting needs.
  • Automation and AI: The top layer is where speed and experimentation take over. It’s PBC automation, data ingestion, confirmation tools, and emerging AI solutions – where new technology can be piloted and iterated quickly, but also where governance and risk management become critical.

The last layer is where innovation – and risk – moves fastest. Modern firms need to be comfortable experimenting there while keeping the foundations steady. That means piloting new tools in controlled environments, establishing clear ownership for AI governance, and ensuring that rapid iteration doesn’t compromise audit quality.

4. Best‑in‑breed beats all‑in‑one 

Ten years ago, the safest bet was an all‑in‑one platform – one vendor, one contract, one login. Today, the consensus is shifting.

Open APIs unlocked the shift from monoliths to ecosystems. Instead of settling for one tool that does everything, firms can assemble a stack of specialists.

I want development teams that are hyper-focused on that one problem they’re trying to solve. If they stop innovating, they won’t exist in 1–2 years. That level of pressure on the best in breeds is amazing.
David Rich
Senior Manager at Clark Schaefer Hackett

The trade‑off is complexity. Multiple vendors means multiple contracts, pricing models, and support channels. And while smooth integrations and vendor collaborations aren’t always a given, when they do happen, the upsides are clear: faster innovation and more resilient stacks.

All‑in‑one is a dying thought. I don’t think you’re going to have an all-in-one tool that can truly do everything we want it to do. Let's allow firms to choose the best tools for the job, and APIs to be able to make that work. That’s great for the industry.

5. The audit tech stack modernization roadmap

What’s next? For most firms, the answer is depth, not breadth. Panelists emphasized consolidating the adoption of the tools you already have before implementing new ones.

David framed near-term focus on driving adoption and broadening use cases across existing platforms. Beyond that, his biggest bet is agentic AI – systems that can take initiative and handle multi‑step audit tasks. “That’s probably my biggest focus aside from our existing stack,” he said.

Andy emphasized culture. Change fatigue is real, but his mantra is that something should always change. 

I don't want the expectation that this busy season is going to be the same as last busy season. We're learning something new before the next busy season.
