Accelerating audit efficiency: How Sensiba LLP streamlined technical research and document management with CoCounsel Audit
Sensiba revolutionized their audit and accounting efficiency by piloting CoCounsel Audit, an AI-powered tool that delivers instant, citation-backed answers to complex technical questions and automates the extraction of key terms from lengthy legal documents. This case study reveals how flexible adoption and smart use of templates empowered over 100 staff to streamline workflows, boost consistency, and embrace innovation without sacrificing professional judgment.
Introduction: Early AI adoption
Sensiba LLP, an independent, partner-owned Top 75 U.S. accounting firm with a global footprint, has built its reputation on collaborating with clients to increase efficiency, mitigate risk, and embrace emerging opportunities. As a certified B Corp with operations across the Americas, Europe, Australia, and beyond, the firm maintains a culture where people, families, and communities thrive while providing accounting, tax, risk assurance, and consulting services.
Sensiba prides itself on having a mindset that is open to technological adoption. When the firm explored how AI tools could introduce efficiencies and change the way they work, they became one of the first companies to use CoCounsel in its Audit and Assurance department. After introducing it through a pilot program designed to test its research efficiency capabilities, CoCounsel was integrated into the audit department's workflow and adopted by over 100 professionals.
The firm's approach to AI adoption was deliberate and measured, focusing on responsible implementation that would enhance — not replace — professional judgment. This philosophy aligned perfectly with CoCounsel's capabilities, setting the stage for meaningful transformation in how Sensiba's audit teams conduct technical research and analyze complex documents.
“CoCounsel is like my assistant or staff that actually understands accounting and tax language. You can ask it complex technical questions in plain English, and it will give you a clear citation-backed answer.”

Challenge: Time-consuming research slows audit teams
The audit team at Sensiba faced several time-consuming challenges that impacted efficiency and consistency.
One of the most significant challenges was how time-consuming technical research had become. Staff often spent 30 to 45 minutes digging through accounting guidance and drafting accounting memos from scratch. This extensive research time led to delays in project timelines and potential inconsistencies in how different team members approached similar issues.
In venture capital audits, Limited Partnership Agreements (LPAs) serve as foundational documents outlining the economics and operations of a fund. These lengthy legal documents are essential for validating whether investments and capital allocations align with agreed-upon terms. Traditionally, summarizing LPAs was an extremely time-consuming process, requiring manual extraction of key terms for audit testing and financial disclosures. Similar challenges existed with other foundational documents like certificates of incorporation for technology companies and adoption agreements for employee benefit plan audits.
Beyond operational challenges, Sensiba faced a broader strategic challenge: how to embrace AI in a responsible way that would encourage staff to apply professional judgment rather than blindly rely on technology. With other technical implementations happening simultaneously, there was concern about "change fatigue" from introducing yet another technology into the workflow.
“One of the most meaningful impacts of this software on our firm is to give us the real opportunity to embrace AI in a responsible way. The mindset around AI is just as important as the tool itself, and CoCounsel helps us to shift that mindset.”

Solution: CoCounsel saves time and increases efficiency
CoCounsel addressed Sensiba's challenges through two primary capabilities: intelligent technical research and customizable document analysis templates.
CoCounsel alleviates research bottlenecks by providing quick and structured answers to technical questions. Instead of spending time researching a complex accounting issue, audit staff can now find solid responses within minutes, with relevant guidance displayed directly alongside the response. The citation-backed answers ensure that staff aren't blindly trusting AI output — they can see the underlying accounting standards and guidance that support each answer.
This approach reinforces Sensiba's commitment to professional judgment. As Carson Chen, Senior Audit Manager, explains: "CoCounsel is like my assistant or staff that actually understands accounting and tax language. You can ask it complex technical questions in plain English and it will give you a very clear citation-backed answer, often with the relevant ASC guidance on the right side. It's pretty fast, consistent, and it helps you to solve problems while learning along the way."
The audit team created workspace templates specifically designed for their most common document types. For LPAs in venture capital audits, these templates allow the team to extract key economic terms from lengthy legal documents within minutes. The automated process generates consistent summaries that are ready for review quickly, enabling easy comparison against prior versions or amendments.
The success with LPA templates led to expansion into other audit areas. The team created similar templates for certificates of incorporation (for technology companies) and adoption agreements (for employee benefit plan audits). The use of CoCounsel workspaces proved particularly valuable because keyword searches alone wouldn't work effectively on these complex documents — CoCounsel's AI-powered understanding could identify relevant information even when terminology varied.
The rollout of CoCounsel was deliberately timed for a busy period (January) so the team could learn using the developed workspaces while engaged with their client work. Rather than enforcing use, the focus was on educating staff about the tool's existence and potential applications, allowing them to explore and integrate it into their workflows naturally.
This low-effort approach proved highly effective. Unlike some AI tools with specific, limited terms of use, CoCounsel offered broader applications. The introduction felt minimally disruptive because CoCounsel served as an aid to completing existing workpapers rather than dictating a new approach. This flexibility was key to realizing strong adoption across the department.
Outcomes: Transform audits and preserving professional judgment
An often-overlooked benefit emerged in professional development. Because CoCounsel provides answers with citations and displays relevant accounting guidance alongside responses, staff members solve immediate problems while simultaneously learning the underlying standards. As Carson Chen notes: "That is a big deal for us because our firm is focused on responsible AI adoption and one of our key goals is to encourage staff to not blindly rely on AI, but to still apply professional judgment. The CoCounsel approach helps reinforce that and staff can resolve an issue, while also learning the underlying standard in the process."
Despite concerns about introducing another technology during a period of multiple technical implementations, CoCounsel's introduction felt low-effort and was well-received. The flexibility to use it as an enhancement to existing workflows, rather than a replacement for established processes, proved crucial to this success.
Perhaps most significantly, CoCounsel has enabled Sensiba to establish a model for responsible AI adoption that preserves and enhances professional judgment. This cultural shift positions the firm well for future technological innovations and demonstrates to clients and staff alike that technology and human expertise can work in harmony.
