In 2012, Tim Abbott walked into a Chicago accounting firm that still tracked tax returns on a clipboard. No electronic filing, no digital documents, just alphabetical lists checked off by hand. Eight years and one pandemic later, he owned that practice and another 40-year-old firm, and had transformed both into a thriving $2.4 million modern business while keeping nearly all their legacy clients.
In this episode of “Who’s Really the Boss?”, hosts Rachel and Marcus Dillon get Abbott’s story about acquiring and modernizing two multi-generational accounting firms in the Chicago suburbs. The journey involved a delicate balance between honoring tradition and driving innovation.
Starting With “No Is a Complete Sentence”
Abbott’s path to firm ownership began with an unexpected philosophy. “The best piece of advice I received,” Abbott shares, “is that no is a complete sentence.” This mantra guided his transformation of M.J. Vandenbroucke from a clipboard-based operation into a modern firm serving law offices, financial planners, and medical practices across the Chicago suburbs.
Abbott brought a fresh perspective to a firm frozen in time. With three daughters at home and a wife working as an elementary school nurse, he understood the importance of setting personal and professional boundaries. That discipline proved essential when navigating the complexities of modernizing practices that had operated the same way for decades.
The firm he joined in 2012 wasn’t broken; it was just stuck. With ten employees, many boasting 20 to 35 years of tenure, M.J. Vandenbroucke had successfully served clients since 1970. But success had bred complacency. The firm ran entity returns through UltraTax while processing individual returns in ProSeries, losing K-1 import capabilities. When Marcus Dillon learned about this setup, lost efficiencies immediately came to mind.
The Art of Incremental Change
Rather than shocking the system with sweeping reforms, Abbott orchestrated a deliberate five-year modernization plan. Each year from 2012 to 2017 brought one major improvement. Electronic filing replaced paper submissions. Digital file cabinets eliminated physical storage. Client portals opened new communication channels. Direct deposit streamlined payments.
“When you’ve been doing things largely the same way for 30 years, it can be challenging to change,” Abbott observed. His measured approach respected the staff’s experience and the clients’ expectations. This patience wasn’t passive; it was strategic.
Abbott received some invaluable advice about acquisitions: “Unless something is functioning horribly, don’t change anything you don’t have to” during the first year. By observing existing workflows and understanding why certain processes existed, he could distinguish between outdated habits and practices that genuinely served clients well.
This incremental approach delivered measurable results. Staff gradually embraced new technologies without feeling overwhelmed. Clients experienced improvements as enhancements rather than disruptions. Most importantly, the firm maintained its operational stability while building capacity for future growth. By 2017, Abbott was ready to acquire the practice, having proven that modernization didn’t require revolution.
When Coffee Leads to Acquisitions
Abbott’s second acquisition offers a lesson in professional serendipity. At a conference, he sat next to a CPA from New Jersey who mentioned knowing someone near Abbott’s Chicago office. “That casual breakfast conversation led to coffee meetings,” Abbott recalls, which evolved over two years into an acquisition agreement finalized in 2020, during the pandemic.
The 75-year-old owner of this second firm had no succession plan. Like M.J. Vandenbroucke, this practice had operated for nearly 40 years with established processes and long-term client relationships. Abbott acquired the business and moved the entire operation to their larger office space, merging two firms with a combined 90 years of history.
Both transitions followed a similar pattern, with previous owners staying on for approximately three years. The first owner planned to work through the 2020 tax season, but when COVID extended deadlines indefinitely, he decided to leave on June 30th. “If we don’t just rip the Band-Aid off, I’m going to be here forever,” he told Abbott.
The second owner maintained his full role for the first year, with Abbott sitting in on client meetings but not directly involved in work. Years two and three saw gradual transitions until Abbott hired a replacement CPA. This extended handoff was crucial for client retention.
Building Trust Through Continuity
Abbott presented the second acquisition as a “merger” rather than a takeover, maintaining all existing staff to ensure continuity. The messaging mattered. “There was actually a pretty big sense of relief that we had a continuity plan in place,” Abbott notes. Clients who had watched their CPA age into his seventies welcomed the security of younger leadership backed by familiar faces.
The human element proved crucial. When a bookkeeper has been working with a client for 22 years and stays through the transition, “there’s a lot of comfort there,” Abbott observed. This continuity helped maintain exceptionally high client retention rates through both acquisitions.
Not all relationships transferred smoothly, though. Referral sources—particularly those with personal connections to previous owners—were harder to retain than clients. “The owner’s friend, people he grew up with, high school buddies, fraternity friends, some of those don’t transfer very well, no matter how hard you try,” Abbott acknowledged.
Marcus Dillon confirmed this challenge from his own experience. “The referral sources who referred clients to the firm while it was owned by another CPA, some of those loyalties go away.” This means firms must activate new business development strategies to replace lost lead sources.
Discovering Hidden Challenges and Strengths
Post-acquisition discoveries revealed problems and unexpected assets. Abbott uncovered situations like clients receiving May financials in September because “they’re always late and we have to call three times.” Marcus Dillon shared similar experiences, noting how sellers suddenly reveal after closing which clients are “awful to work with.”
But Abbott also discovered the firm’s employees had an exceptional ability to explain complex concepts without condescension. “We’ve received several referrals from prospects who said, ‘so and so told me to call you, I need help. And they said you wouldn’t make me feel dumb.’” This skill became a cornerstone of the firm’s value proposition.
The firm’s recent website redesign reflects this evolution. Rather than hiding behind traditional industry opacity, Abbott chose radical transparency with published pricing. “We’re not out here to compete with anybody on price, but you have no reason to hide it.” The new site at mjvcpa.com has already generated upsells from existing clients who discovered services they didn’t know the firm offered.
The Power of Peer Connections
Throughout these transitions, Abbott credits peer relationships as essential to survival. “COVID was brutal for everybody,” he reflects. “I don’t know that I would still be here running a firm without just some of those relationships that got me through the tough times.”
His involvement in mastermind groups and communities like Collective by DBA provided crucial support. “Having the resources of other firm owners that have literally walked in your shoes and faced the same challenges, getting their perspective, wisdom, and advice has always been hugely beneficial to me.”
These connections even facilitated acquisitions within the group. Marcus Dillon recalled how a conversation with one mastermind member led to another acquisition for his firm. The lesson? Professional relationships often yield unexpected opportunities.
Building for the Next 50 Years
Today, M.J. Vandenbroucke employs 13 team members in a hybrid environment, with staff in the office one to four days per week and two fully remote employees.
After years of integration work, they’ve finally standardized processes across both acquired firms. Goals have shifted from survival to optimization. The firm has the capacity to grow without adding headcount.
“When you take the right steps, generally the results follow,” Abbott reflects. His patient approach to building on established foundations while creating new value positions M.J. Vandenbroucke for another 50 years of service.
For accounting professionals considering acquisitions, Abbott’s experience offers valuable lessons. Respect the pace of change. Invest in extended transitions that transfer trust, not just client files. Honestly evaluate what deserves preservation versus transformation. And perhaps most importantly, remember that “no is a complete sentence,” because boundaries matter when managing complex transitions.
