Those recurring review comments that keep popping up across your team? Sam Mansour, CPA, did the math and it should make every audit firm leader pay attention. When you multiply these small inefficiencies across your entire practice, they balloon into 1,000 hours of wasted time annually. That’s half a full-time position lost to preventable mistakes, year after year.
In this episode of Audit Smarter, hosts Sam and Abdullah Mansour explore how firms can transform their most frustrating pain points into powerful improvements. Rather than treating each mistake as an isolated problem, Sam shares a systematic approach that turns recurring challenges into opportunities for growth.
The Hidden Cost of Repeated Mistakes
Sam starts with a simple example: a staff member who keeps forgetting to include references from cash testing leads back to supporting check registers. It seems minor until you realize this same mistake is happening across multiple team members, multiple engagements, and multiple years.
“Without reflection, mistakes repeat,” Sam emphasizes. “Without capturing what we’ve learned, we’re almost guaranteed that they’re going to repeat themselves.”
The math becomes staggering when you look across an entire firm. Sam breaks it down. “Let’s say they’re 15-minute issues. If you multiply that by 1,000, now it’s starting to take a lot of time. Because it’s not just one person, but multiple people doing it across multiple engagements.” With an average person working 2,080 hours per year, those 1,000 hours of wasted time equal half a position.
What’s particularly frustrating is that these aren’t random, one-off errors. “Very rarely is it just this one person making this one mistake and you’re never going to see that mistake ever again from different team members,” Sam explains. “People tend to make similar mistakes.”
From Personal Notes to Firm-Wide Knowledge
Sam’s solution is simply to create a lessons-learned log. At the most basic level, this might be a Word document where a preparer titles a section “Cash” and documents specific review comments they receive.
“When you go and test that section again, you need to review your own work,” Sam explains. “You complete this testing in that cash section. Next, you need to realize, okay, I commonly forget to make the reference back from what I see in this lead schedule.”
But personal documentation is just the beginning. Abdullah suggests using OneNote for better organization. “OneNote helps organize it so that you can have one folder for one client,” he explains. “And then you can have several different pages essentially underneath that. So just organizes it a lot better. It’s like a file structure on a network.”
The real power comes when firms turn these individual insights into searchable, firm-wide resources. Sam shares his own recurring challenge with farm audits. “Every year I get into those work papers, I’ll be like, oh shoot, how did those journal entries work? What was that again? Because I only tested like one or two of these a year.”
The solution is to create what Sam calls “a trail of breadcrumbs,” detailed guidance that lives outside the formal audit documentation. This might include written instructions, screenshots of calculations, or even “record video of yourself talking about it.”
By organizing these resources into categories like planning, fieldwork, and wrap-up, firms create an institutional memory that helps everyone, but especially new team members who can access years of accumulated wisdom before their first engagement.
Post-Engagement Debriefs Can’t Be Optional
Sam acknowledges the common perception of post-engagement debriefs as just administrative work. Teams finish one audit and want to jump straight into the next, treating reflection as a luxury they can’t afford.
But Sam insists these debriefs are critical. Structure these meetings by asking three essential questions: What worked? What didn’t work? Where did we get stuck?
Timing matters enormously. “If you wait six months to ask what worked and what didn’t work during busy season, it’s difficult to recall all those little instances,” Sam explains.
The solution is to make debriefs mandatory. “Don’t make it an optional thing,” Sam insists. “We need to sit down, discuss, and reflect.”
These insights then translate into concrete improvements. Sam provides specific examples of how to use what you learn:
- Update templates. Add conditional formatting that turns cells green when correct values are entered, creating visual confirmation that eliminates data entry errors.
- Improve checklists. Sam says people like to complain about adding more things to the checklist. His response is practical: “We should continue to add things to the checklist until we stop missing them.”
- Document compensating controls. In smaller environments where proper segregation of duties isn’t possible, teams often miss compensating controls. Sam’s solution is to put a header in the template that says Compensating Controls. Highlight that section in yellow, and force auditors to fill it out when they’re in the field.
Getting Your Team to Actually Buy In
“They’re filling out more paperwork. Their checklists are becoming longer, their templates are becoming longer. They’re asked to do more work. People get frustrated,” Sam says, acknowledging the pushback firms encounter.
The key to overcoming resistance is to explain the “why” behind every change. Using the compensating controls example, Sam shows how to frame it. Explain why smaller clients need these controls, how missing this documentation puts the firm at risk, and why this has emerged as a firm-wide trend.
Most importantly, show the math. “Yes, it takes an extra 15 minutes to fill out this work paper,” Sam quantifies, “but on the back end it costs us, on average, an hour. So we’re saving 45 minutes and we’ve improved our audit quality.”
Recognition matters too. “Recognize people who help us improve as a firm,” Sam emphasizes. When you publicly acknowledge team members who contribute ideas, it shows everyone that the firm values continuous improvement.
The payoff is clear when teams understand the bigger picture. “Improvement is easier to embrace when it’s linked to wins, not just extra tasks,” Sam explains. The wins include reduced hours, better documentation, less stress during peer reviews, and becoming better auditors overall.
Building a Culture Where Every Audit Makes You Stronger
The ultimate transformation happens when learning becomes part of your firm’s DNA. “We do work and then we reflect on that. What did we do good? What did we do bad? What needs to improve? What needs to change?” Sam describes. “We take those lessons learned and then we implement change in the firm. Now it’s an upgrade.”
This creates a powerful shift in how teams approach their work. “Eventually it becomes so ingrained in people that they go out into the field with that mentality from the very beginning,” Sam observes. “If you know you’re going to have that conversation, the next audit you go out on, you don’t want come to the next meeting and say, oh shoot, we missed this.”
The benefits extend beyond efficiency. Sam notes that when professionals evaluate career moves, they ask themselves if working at a firm will enhance their resume. “It’s really important to have a culture of learning, to have a culture of enhancing and moving forward,” he emphasizes.
Perhaps most remarkably, this approach transforms the audit environment itself. “I have found audit environments like that are much less stressful to be in because everyone’s just so ahead of the game and so proactive,” Sam reflects.
Some might think this vision sounds unrealistic, but Sam addresses this directly. “For a lot of audit firms listening to this, they’re thinking this is an unrealistic dream. But it’s very realistic if the people in the firm buy into this idea.”
Over time, Sam promises, “your audit methodology becomes smarter, more efficient and more resilient because now you’re not just digging holes and going home. You’re you’re thinking it through.”
Turn Your Next Review Comment Into Progress
The difference between firms that fight the same battles year after year and those that continuously improve isn’t talent or resources. It’s the discipline to capture, analyze, and act on lessons learned.
Sam’s framework shows every review comment, debrief insight, and team suggestion can strengthen your entire firm. When you transform individual experiences into institutional knowledge, optional debriefs into mandatory investments, and isolated improvements into a learning culture, each audit makes your firm stronger.
