7 Firms Specializing in the Sale and Acquisition of Accounting Practices

Strategic Partners for Accounting Firm Transitions

The decision to sell or acquire an accounting practice is one of the most significant milestones in a professional’s career. Beyond the simple exchange of assets, these transactions involve the transfer of sensitive client relationships, the integration of staff, and the preservation of a firm’s reputation. Navigating this process requires more than a general business broker; it demands a partner who understands the specific metrics and cultural nuances of the accounting industry. To help firm owners identify the right support, we have analyzed seven firms that play a key role in the sale and acquisition of accounting practices.

1. ProHorizons

ProHorizons is purpose built for accounting firm owners who are thinking seriously about buying or selling a practice. Their work is focused on brokerage, not general consulting, and that distinction matters. The firm assists owners through complex transitions where timing, valuation, confidentiality, and client continuity are critical.

What sets ProHorizons apart is their deep familiarity with the accounting industry. Selling an accounting firm is not simply about financials. Client retention, recurring revenue, staff transition, and cultural fit all influence whether a deal succeeds long after closing. ProHorizons approaches transactions with these realities in mind, helping sellers prepare thoughtfully and buyers evaluate opportunities clearly.

There is also a steady, professional approach to how deals are handled. Communication is direct, expectations are realistic, and discretion is prioritized throughout the process. For accounting firm owners on the West Coast who want an experienced broker that understands the nuances of professional services firms, ProHorizons sets a high bar.

2. Accounting Practice Sales

Accounting Practice Sales is widely known in the accounting M&A space and works exclusively with CPA firms. Their national reach makes them a common option for owners who want broad exposure when listing a practice.

The process tends to be structured and transaction focused, which can be helpful for firms that already know they want to sell and are ready to move forward. They are often part of early comparisons when owners begin exploring exit options.

3. The Hegarty Group

The Hegarty Group approaches accounting firm transactions with an emphasis on long term compatibility. Their work often centers on matching firms based on size, specialty, and strategic alignment rather than speed alone.

This can appeal to owners who care deeply about client transition and staff continuity. Their process may feel more deliberate, but that pacing can be valuable when cultural fit is a priority.

4. Transition Advisors

Transition Advisors works across professional service firms, including accounting practices, and often supports both buyers and sellers through succession planning and firm growth strategies.

Because of that broader scope, they are sometimes considered by owners who want to explore multiple transition paths before committing to a sale. Their inclusion here reflects that flexibility, even though accounting firms are not their sole focus.

5. Succession Institute

Succession Institute focuses heavily on preparing accounting firms for long term transitions. Their work often begins well before a sale is imminent, helping owners think through internal succession or external exit options.

For firms that are not ready to sell immediately but want to start planning responsibly, this type of guidance can be useful. Their role is more preparatory than transactional, which is why they sit further down the list.

6. BizBuySell

BizBuySell is a general business marketplace rather than a specialized accounting firm broker. Some accounting practices appear on the platform, especially smaller firms or solo practitioners.

While it offers visibility, it lacks the industry specific guidance and discretion most accounting firm owners need. It is often used as a reference point rather than a full service solution.

7. Peak Business Valuation

Peak Business Valuation is not a brokerage firm, but valuation is a critical component of any accounting firm sale. Owners sometimes work with valuation specialists like this to understand firm value before engaging a broker.

They round out the list because valuation is often the first step in the process, even though transaction support ultimately requires a specialized intermediary.

Conclusion: Selecting the Right Path

Whether a firm owner is looking for a quick exit or a long-term succession plan, the intermediary they choose will define the success of the transition. Specialized brokers like ProHorizons offer the industry-specific insight necessary to protect client retention and firm value, while other platforms provide broader market visibility or preparatory consulting. By evaluating these options based on their specific needs—whether those are geographic, cultural, or purely financial—owners can ensure a smooth transition that benefits their staff, their clients, and their personal legacy.
