Tips for Successful Post-Completion Integration in M&A: Insights from John Holliday

Mergers and acquisitions (M&A) are often discussed in terms of strategy, valuation, and the pre-deal process, but the real challenge, and the true determinant of long-term success, lies in post-completion integration. John Holliday, Partner at Pocknolls Accountants, has firsthand experience managing this crucial phase, offering valuable lessons on how to integrate teams, manage branding, retain clients, and navigate fee adjustments. Drawing on his insights, here’s how to approach post-completion integration effectively to set your firm up for lasting success.

1. Integrating Teams: Building Trust and Culture

A smooth integration starts with people. John highlights that trust and cultural alignment are essential from the start. “If at any point, you're not getting on with the existing partners or there’s a trust issue, that should be a deal breaker,” he says. Building trust with key partners before the deal closes helps lay the groundwork for a successful transition. John emphasises early engagement with senior team members as a critical step in assessing cultural fit and establishing trust. “If you can’t meet the team before acquisition, that’s a red flag,” he notes. He shared an example where an initial team-building exercise made a significant difference. “We organised a day-long workshop where teams collaborated on problem-solving tasks. It broke down barriers and sparked conversations that didn’t happen in regular office settings,” he said. This proactive approach helped create an environment where teams felt unified and engaged from the start. After the deal closes, maintaining momentum is crucial. While casual social events like drinks are useful, John suggests that structured activities foster deeper connections. “Drinks are nice, but they can be segregated. A structured team event forces communication and helps everyone get to know each other,” he explains.

2. Branding Decisions: Navigating the Transition

Deciding how and when to rebrand an acquired firm can impact both internal team morale and client perception. John’s strategy varies based on the nature of the acquisition. “In smaller deals, we’ve rebranded right away due to strong partner support, but for firms with significant goodwill, a gradual co-brand strategy works best,” he says. John recalled a specific instance where an immediate rebrand led to questions from long-standing clients. “We had to manage client concerns by emphasising how the rebrand meant more comprehensive service offerings,” he shared. This transparent communication transformed initial scepticism into client buy-in and even enthusiasm.

Strategic Approaches to Branding:• Immediate Rebranding: Effective when the acquired firm aligns closely with your identity and there’s partner buy-in.• Co-Branding: Ideal for firms with a well-established local reputation, ensuring trust is maintained during the transition.Clients are more likely to embrace a new brand when they understand the benefits, such as enhanced services and broader expertise. John’s experience underscores the importance of clear and consistent messaging throughout this process.

3. Client Retention: Keeping Clients Loyal

Retaining clients after an acquisition is a cornerstone of successful integration. John emphasises that maintaining client trust requires consistency and proactive communication. One of Pocknolls’ strategies involves earn-out agreements to keep outgoing partners involved. “We align interests by offering 25% for four years, ensuring partners stay motivated to retain clients,” he explains. John shared how this strategy played out in practice: “In one acquisition, the earn-out agreement was a turning point. The outgoing partners remained engaged, which reassured clients and maintained the relationship continuity they valued.” This thoughtful approach kept client turnover low and ensured that clients felt secure during the transition. Clients often worry about how changes will impact their services. John advises keeping familiar faces in client interactions to help ease these concerns. “Clients often worry about changes. Ensuring they see familiar faces and hear from their existing partners helps them adjust,” he notes.

4. Fee Management: A Gradual Approach

Fee structures can be a sensitive topic post-acquisition. John’s approach is to maintain stability initially, avoiding client discomfort during a transitional period. “We have a centralised quoting system,” he shares, which ensures transparency and consistency when adjustments are needed. John highlighted an instance where proactive communication was key: “A client voiced concerns about potential fee changes after an acquisition. We addressed this by sitting down with them and explaining the enhanced support they’d receive and how that justified the gradual adjustment.” This open, honest dialogue reinforced trust and helped clients see the value of the changes.

Approach to Fee Adjustments:• Initial Stability: Start with existing fee structures to provide continuity.• Gradual Alignment: Introduce fee changes over time with clear communication about the value clients will receive.By framing fee adjustments around added value and client benefits, firms can manage expectations effectively and foster long-term loyalty.

5. Systems and Processes: Phased Integration

Integrating operational systems can be one of the most complex parts of post-acquisition. John admits that Pocknolls initially delayed changes, a lesson that taught them the importance of balance. “We were probably too kind, waiting six to twelve months to make changes. But now we know that balance is key,” he reflects. Phased rollouts, combined with proper training and support, have since become John’s preferred approach. He shared how resistance was mitigated through tailored training: “Accountants don’t like change,” he joked. “But we showed them how these changes would streamline their workflow through a series of training sessions and one-on-one support.” This step-by-step integration ensured that teams adapted gradually without feeling overwhelmed. Interestingly, John noted that some acquired firms brought valuable insights to Pocknolls. “They were doing things better than us, and we were open about that. We learned from them and improved our own processes as a result,” he said. This openness to learning created a collaborative atmosphere that benefited both sides.

Final Thoughts: The Power of Communication

Throughout the post-completion integration process, communication remains the most critical element. “Be honest and open, not just with the partners but the entire team,” John emphasises. Transparent, ongoing dialogue builds trust and encourages buy-in, making integration smoother and more effective.

Top Lessons Learned:

• Start with Trust: Build relationships with key partners before the deal is signed to set the stage for successful integration.

• Maintain Clear Communication: Keeping everyone informed fosters a collaborative environment and confidence throughout the transition.

M&A success is measured not just by closing the deal but by what happens after. Effective integration, marked by trust, thoughtful strategy, and open communication, lays the foundation for long-term growth and client satisfaction. If your firm is navigating M&A, develop a comprehensive post-completion integration plan that prioritises team dynamics, client engagement, branding strategy, fee management, and system integration. The care you put into these areas will shape the success and sustainability of your acquisition.
