From Vision to Workflow: Thomson Reuters Advances AI-Enabled Audit Through Guided Assurance
With new ecosystem partner capabilities now rolling into Guided Assurance, Thomson Reuters is helping audit firms automate key areas of the engagement while keeping trusted PPC methodology at the center, writes Corey Wells
There’s no shortage of AI tools available to auditors right now. The real question is what actually works inside an audit engagement. Firms are navigating tighter capacity, increasing complexity, and growing client expectations around quality and defensibility. At the same time, many AI tools still sit outside the workflow, creating more fragmentation instead of less.
At Thomson Reuters, we bring auditors advanced audit technologies. CoCounsel Tax & Audit and Audit Intelligence Analyze launched in 2025, offering AI-powered solutions to help audit professionals work faster and with greater confidence.
Partnerships are equally central to our innovation strategy, with an approach centered around methodology. When we first shared our vision for an AI-enabled audit ecosystem, the focus was clear: help firms modernize without asking them to walk away from the methodology they trust and their existing technology investments.
The role of the integrated ecosystem
Audit is not a single workflow, and it won’t be solved by a single tool. Our intention is to meet firms where they are – and give them an experience with best-in-class options from trusted providers that meet our standards for quality and reliability.
An open ecosystem approach makes it possible to bring together specialized capabilities and integrate them into a cohesive experience, with data being automatically shared with partners embedded in PPC. For firms, that means more flexibility in how they adopt new technologies and less need to manage disconnected tools across the engagement.
Today, we’re seeing that partnership vision come to life inside real, integrated audit workflows.
Over the past several months, we’ve been working closely with a curated set of partners to embed AI-powered tools into our PPC methodology. Those integrations roll into Guided Assurance, with new automated capabilities available to firms within our software.
Embedding partners within PPC
The impact is most visible in complex, manual areas of the audit where teams spend the most time today, such as lease accounting, proof of cash, and financial statement review — and it’s coming to life through our growing network of integrated partners:
Crunchafi: Lease accounting and specialized workflows
Lease accounting continues to be a complex and time-consuming area for many firms. By integrating Crunchafi into audit workflows, teams can automate lease accounting across FASB ASC 842, IFRS 16, and GASB standards, simplifying complex calculations and generating audit-ready schedules and journal entries directly from source contracts.
“Our clients span a wide range of industries and reporting standards, and lease accounting is one of the areas where getting the calculations wrong has real consequences,” said Leander Sico, Partner at Hutchinson & Bloodgood LLP. “Having Crunchafi integrated into Guided Assurance means our team is working from audit-ready outputs tied directly to the procedures we’re following. That connection between methodology and software gives us greater confidence in both our team’s execution and the final workpapers.”
Audit Sight: Automated proof of cash
Our integration with Audit Sight brings automated cash analytics directly into the audit workflows – reconciling bank activity against accounting records and producing audit evidence that allows auditors to reduce or eliminate substantive procedures throughout the audit.
“Audit Sight has transformed how we perform substantive testing,” said Mark Welp, Partner at Holbrook & Manter. “By automating testing of routine transactions, our team can focus on higher-value audit work. The recent PPC methodology updates reinforce that this approach is both practical and aligned with professional standards.”
Trullion: Financial statement validation
Financial statement validation and version management are some of the most time and judgment-intensive parts of the audit, but much of the underlying work is repeatable. Through our integration with Trullion, we’re bringing AI-driven automation into math and consistency checks on financial statements, version and prior-year comparisons, and statement structure validation.
“Partnerships drive increased efficiency while enhancing the effectiveness of our audit procedures,” said Mike Reynolds, Partner at Bennett Thrasher. “Trullion and Thomson Reuters have consistently delivered on the vision, responsiveness, and execution necessary to solve these key components that differentiate market-leading solutions. Trullion’s financial statement validation capabilities available from Thomson Reuters Guided Assurance creates a fully integrated, AI-powered workflow, reducing friction throughout the entire financial reporting quality control process. We know this is just the tip of the iceberg of what this partnership can unlock and we are excited to see what comes next.”
Across each of these areas, the goal is to reduce manual effort, increase consistency, and keep work anchored in a trusted methodology.
Looking ahead
Audit is steadily becoming more automated and data-driven. The opportunity is to use that shift to improve both efficiency and quality, freeing up time for auditors to focus on risk, judgment, and insight.
By continuing to invest in both our own capabilities and this broader ecosystem, we’re helping firms evolve their workflows in a way that feels practical, connected, and grounded in the standards they rely on every day. That’s where we’re focused, and where we’ll continue to push the pace of innovation in audit.
