The Bonadio Group, a Top 50 Firm based in Pittsford, New York, has executed 22 successful mergers over the last 27 years, many of which have been overseen by CEO and managing partner Bruce Zicari.
Harvard Business Review found that between 70% to 90% of M&A deals fail, but Zicari has taken a careful approach to make sure the firms mesh together. Last year, Bonadio added Howard LLP, a firm based in Dallas and Webber CPA, a forensic accounting and financial consulting firm in Rochester, New York. In 2021, Bonadio merged in Ganer + Ganer, a firm in New York City. Zicari has five key pieces of advice:
1. Ensure that every leader at your business is 100% in agreement with the acquisition. 2. Define an approach to vetting merger candidates, including reviews of finances and culture. 3. Prioritize post-merger integration, including “buddy systems” and software transition training. 4. Always be deliberate and intentional in your employee and client communication. 5. Consider moving some of your people into a brand new merged in office.
“We’ve done many mergers over the last 25 years, and we’ve certainly learned a lot of good lessons over the years,” said Zicari. “I think we’ve gotten better and better at them. We’ve made a lot of mistakes over the years, but learned from those mistakes. At a high level, we really take our time with mergers. We spend a lot of time on the front end, getting to know the firm that we’re looking at.”

Bonadio partners meet with the other firm’s partners, not only in business meetings, but also at social meetings and dinners. “It usually takes anywhere from six months to almost a year,” said Zicari. “We have a process where we have a very long series of meetings to make sure we get to know each other, to make sure as best we can determine that there is a good cultural fit, and a good alignment of our values and our vision for the future in terms of strategy. If the culture fits, and we see the world the same way, and we have the same values, everything else really works out.”
He views careful due diligence as essential. The firm has a comprehensive checklist for not only the typical forms of due diligence, including legal, financial and IT matters, but it also does a cultural assessment. “We hire an independent third party that knows and trusts us, knows the accounting industry very well, and they go in and meet with the partners of the firm that we’re looking at acquiring, and they do a cultural assessment,” said Zicari. “That’s another checkpoint for us to make sure that we’re doing a merger with somebody who sees the world the same way. That’s so important. If we have a good cultural match, everything else ends up working out. That’s something that’s worked very well for us over the years.”
He sees this as taking a different approach than the increasing number of accounting firms controlled by private equity.
“With all of the recent private equity transactions, I am seeing firms make acquisitions very quickly,” said Zicari. “They’re making a lot of transactions in a very short period of time. Although we’re competing against private equity, I think our advantage is that we are going to take our time. We’re going to get to know them.”
All the partners have to basically agree that the merger is a good move. “In the meetings we have prior to the merger, as well as the cultural assessment, we make sure that there’s clear alignment, that there are clear expectations on both sides, and we make sure that every partner is 100% in,” said Zicari. “We will not do a merger unless every partner is fully committed to the merger. We’ve walked away from mergers because there have been one or two partners not committed, and it just doesn’t work. If the partners aren’t committed, then the people aren’t committed, the clients aren’t committed, so we make sure there’s 100% alignment in that regard.”
The firm makes sure it’s being clear in any employee and client communications about the merger once it has been approved. “We have a very comprehensive communication process whereby we bring a whole team down to announce it to the employees,” said Zicari. “We make sure that all the clients are alerted exactly right at the time of the merger, and some of the larger clients are actually called ahead of time. We spend a lot of time with both the people and our clients post merger, explaining to them all the benefits of the merger.”
Both clients and staff need to be reassured. “We tell them you’re not going to see a lot of change,” said Zicari. “You’re going to continue to deal with the same partners and the same people. You’re going to continue to get the same great service, the same pricing. The benefit is that your firm now has 1,000 people behind them with resources and support to make sure that we can provide every service possible to bring value to those clients. Our philosophy is always just to make sure that we give the merged-in firm the very best resources and all the best service and surround them with the best expertise and resources to serve their clients even better than before.”
Having an integration process for after the merger is essential, “We like to say that once the documents are signed, it becomes official, but that’s just the very start of integrating and becoming one firm,” said Zicari. “We have a whole team of people that spend time in the weeks and months following the merger.”
That can involve relocating some employees. “If it’s a brand new office, we like to move a number of our people into that office, and move them geographically into the new office, to bring our culture to life there,” said Zicari.
“When we went into New York City, we relocated a number of our people from our upstate offices to New York City,” he added. “When we went into Dallas, we moved a number of people from upstate offices to Dallas.”
Younger employees seem to be especially interested in relocating to new offices. “A lot of our young people really jump at the idea of moving from upstate to some of these larger metropolitan areas,” said Zicari. “It’s a great way to transport our culture, bring our culture to life in these new offices, in these larger cities. Our goal is to try to get 10% of our people. If we do a merger in Dallas of 80 people, we try to get at least eight of our people to relocate and move into the new office and be part of the new merger.”
The firm has a “buddy system” in place. “We assign every one of the people in the new firm to somebody in our firm, so they will have somebody that they can call if they need anything,” Zicari explained. “We have a whole team of marketing, HR, IT, finance people that help integrate the new firm into ours. It’s not just the management of our firm that gets involved post integration. It’s really all of our support functions, all of our partners and all of our people through our buddy system. Everybody gets to know each other and work with each other. And then, we spend a lot of time not only integrating the systems, but just educating the new firm on all the different services we have to offer that they can bring to their clients in the months after the merger.”
The Bonadio Group is currently looking at several possible merger candidates. “We’re always meeting with firms,” said Zicari. “We always have a pipeline of potential mergers. Right now there’s somewhere around five or six potential mergers in the pipeline. We are planning on doing two smaller mergers this year, and we really hope to get those closed and make them part of our firm by the October, November or December timeframe.”
One will be in a new territory for Bonadio. “One is in the mid-Atlantic region, so we are kind of moving out of the Northeast into the mid-Atlantic region,” said Zicari. “That’s a new market for us. The other one is a niche practice. They all work virtually. It’s a smaller, boutique niche practice that’s going to bring some expertise to our tax department that they didn’t have before.”
The Bonadio Group regularly holds an Annual Purpose Day in the summer where employees volunteer to help their communities and get to know each other better. “We worked at somewhere around 40 or 50 different nonprofit entities across our footprint, across all of our offices,” said Zicari. “We had about 800 of our people that collectively did charitable projects for the better part of four or five hours, and then afterward we had a big picnic in each of our geographic regions to cap off the day. For a lot of people, it’s one of their favorite days. We really feel like we’re able to make a difference. And collectively, with 800 people working around our footprint, it’s a great way to really have a very significant, measurable, positive impact on many of these charitable organizations. It’s something we’ve been putting on for about five years now, and we’re very happy to give back to the communities that we’re in.”

The accounting profession is undergoing a fundamental structural transition as enterprise finance departments shift from periodic month-end closes toward automated continuous accounting models. By integrating specialized machine learning algorithms directly into enterprise resource planning (ERP) platforms, chief accounting officers are transforming financial reporting from a retrospective exercise into a real-time operational asset.
The Shift from Periodic Close to Continuous Financial Reporting
Traditional accounting workflows heavily relied on manual data reconciliation, spreadsheet calculations, and multi-week closing cycles at the end of each fiscal period. In contrast, continuous accounting frameworks utilize automated software agents to process, validate, and post transactional data in real time as business activities occur.
Automated bank reconciliation tools cross-reference incoming bank feeds, invoice records, and purchase orders automatically. By resolving transactional variances instantly throughout the month, corporate accounting teams eliminate the traditional workload spikes associated with quarterly and annual closes.
Machine Learning in Audit Trails and Anomaly Detection
Advanced natural language processing (NLP) and machine learning tools are redefining internal audit and financial control environments. Automated systems analyze 100% of general ledger entries, identifying anomalous transactions, duplicate payments, and unauthorized journal entries in real time.
Rather than relying on random statistical sampling, corporate internal auditors can focus their attention on high-risk flags automatically surfaced by algorithmic monitoring platforms. This continuous risk assessment strengthens internal controls over financial reporting (ICFR) and significantly reduces fraud risk.
Evolving Roles for Accounting Professionals
As routine data entry and manual reconciliation tasks become fully automated, the skill set required for accounting professionals is shifting toward data analysis, system design, and strategic business advisory.
– Systems Governance: Accountants are increasingly responsible for monitoring algorithmic accuracy and managing data integration pipelines.
– Business Partnership: Finance professionals leverage real-time financial dashboards to advise operational leaders on margin management and working capital allocation.
– Regulatory Compliance Management: Accounting teams utilize automated platforms to ensure compliance with dynamic tax codes and international accounting standards.
Core Implementation Recommendations
1. Deploy Automated Reconciliation Tools: Integrate continuous transaction processing modules into existing enterprise ERP architectures.
2. Establish Algorithmic Governance Controls: Implement strict internal testing protocols to ensure automated accounting rules comply with GAAP/IFRS standards.
3. Reskill Accounting Teams: Invest in training finance staff on data analytics, workflow automation, and predictive financial modeling.
Corporate accounting departments face expanding reporting expectations as international sustainability disclosure standards achieve regulatory enforcement across major global jurisdictions. Chief Accounting Officers (CAOs) and corporate controllers are establishing rigorous internal accounting controls to treat Environmental, Social, and Governance (ESG) metrics with the same data precision, auditability, and governance as traditional financial statements.
Regulatory Harmonization Under Global Sustainability Frameworks
The implementation of standardized sustainability reporting frameworks—notably rules established by international sustainability accounting boards—has created unified expectations for public and large private enterprises. Corporations must report standardized metrics covering greenhouse gas emissions (Scope 1, 2, and material Scope 3), energy utilization, workforce demographics, and supply chain governance.
In Europe and other participating international jurisdictions, double materiality principles are mandatory. Under double materiality, organizations must report both how external sustainability risks impact corporate financial performance, and how internal corporate operations affect surrounding environmental and social structures.
Integrating Sustainability Metrics into Core ERP Systems
To provide auditable non-financial data, enterprise organizations are integrating specialized carbon accounting and ESG management platforms directly into core ERP systems. Automated data collectors capture energy utility invoices, logistics fuel consumption metrics, and vendor compliance records in real time.
Establishing automated, traceable data pipelines ensures that non-financial reporting is supported by clear audit trails. This structured approach allows external financial auditors to provide reasonable assurance on sustainability disclosures during annual corporate reporting cycles.
Financial Impacts and Capital Market Disclosure
Accurate ESG reporting directly influences corporate cost of capital and institutional credit ratings. Commercial lenders and institutional asset managers systematically incorporate sustainability metrics into risk pricing models. Companies that demonstrate transparent, verifiable progress in operational energy efficiency and climate risk mitigation benefit from expanded access to green bond markets and lower debt pricing.
Action Steps for Accounting Leadership
1. Implement Double Materiality Frameworks: Conduct comprehensive assessments to identify material financial and operational sustainability metrics.
2. Build Auditable Non-Financial Data Pipelines: Automate ESG data collection within core accounting software to ensure data integrity.
3. Align Sustainability with Annual Financial Filings: Prepare non-financial disclosures concurrently with financial statements to satisfy regulatory audit expectations.
Internal audit departments and corporate risk managers are modernizing internal control frameworks by shifting from periodic sampling techniques to continuous monitoring and machine learning analytics. As operational data volumes increase across enterprise organizations, automated control testing ensures financial integrity, prevents corporate fraud, and streamlines annual audit engagements.
The Limitation of Periodic Audit Sampling
Historically, internal and external auditors evaluated internal controls by reviewing random samples of financial transactions—often analyzing less than five percent of total ledger entries. In complex enterprise environments, periodic sampling methods carry inherent risks of overlooking localized financial misstatements, unauthorized disbursements, or operational control breakdowns.
In 2026, progressive internal audit functions are utilizing automated continuous monitoring platforms that evaluate one hundred percent of financial transactions in real time. Continuous control auditing systems continuously monitor general ledger entries, procurement approvals, and expense reimbursements across all operating subsidiaries.
AI-Powered Fraud Detection and Anomaly Identification
Machine learning models trained on historical corporate financial data excel at identifying subtle transactional anomalies that indicate potential fraud or operational error. Automated systems instantly flag duplicate invoice payments, unapproved vendor creation, unusual journal entry timing, and unauthorized override of authority thresholds.
When an anomaly is detected, the automated auditing platform generates an instant risk alert, allowing internal audit teams to investigate root causes immediately. Early detection prevents minor operational errors from escalating into material weaknesses in financial reporting.
Streamlining External Audit Preparation
Continuous internal control monitoring delivers significant benefits during annual external financial audits. External audit firms can review continuous audit logs and automated control testing documentation, reducing the time required for manual field testing.
This integrated approach lowers overall audit compliance fees, reduces administrative burdens on corporate accounting staff, and provides senior management and audit committees with real-time visibility into the organization’s overall risk profile.
Core Implementation Guidelines
1. Transition to 100% Data Testing: Replace legacy sampling methods with automated continuous audit monitoring systems.
2. Deploy Anomaly Detection Algorithms: Implement machine learning models to identify unauthorized transactions and operational control overrides.
3. Align Internal and External Audit Workflows: Coordinate continuous control testing protocols with external auditors to optimize annual compliance cycles.
