A five billion dollar merger is capable of shaking the foundation of a company and has the potential to change the narrative of an industry.
With Grant Thornton Advisors announcing their intention to merge with CBIZ, the deal became an important headline in the US accounting market. In case of a successful merger, it will place Grant Thornton among top five accounting companies in America, leaving behind such giants as Deloitte, EY, KPMG, and PwC. It is estimated that the merged company will earn more than $5 billion in the United States and close to $7.5 billion around the world.
Yet, the biggest question may not be:
"How big will the merged company become?"
The question that matters more may be:
"What does this merger mean for the industry as a whole?"
The answer points toward a future shaped by technology and scale, talents, improved operational efficiencies, and better support systems.
For CPA firms, the merger of Grant Thornton and CBIZ is not just another news about a merger and acquisition. It is a sign that the industry is evolving and that companies of any size will need to rethink how to increase capacity and grow.
The Deal is Big. The message behind it is Bigger.
CBIZ is being taken over by Grant Thornton in a transaction that stands among the biggest acquisitions in accounting for decades. The approximate value of the deal is nearly $5 billion and is expected to close in Q4 2026 as soon as the necessary approvals are obtained.
This means that there are two players with solid histories in the fields of tax, accounting, and consulting coming together to maximize their service delivery. Once the transaction is finalized, Grant Thornton will be able to access new opportunities for assisting its clients in numerous industries around the globe.
Yet, it should be stressed that the acquisition worth mentioning is about more than just money being at stake and persons being involved into the process.
At this moment, it should be mentioned that the market of accounting is evolving and the companies are in search of new methods of acquisition in order to satisfy the needs of the clients.
The methods of expanding the companies' presence have changed over the time. Acquisition of new technologies and finding partners comes first before establishing new branches or employing more staff.
The Accounting industry Is moving toward greater scale
For years, accounting firms relied on referrals, relationships, expansion, and growing their internal people to grow their business. These methods are still relevant today. Nonetheless, things have changed now.
Clients want more than just compliance services from accountants. They expect accountants to have their bookkeeping on time, give them strategic advice, and provide information about a leading technology. The firms are experiencing greater workloads, changing rules and regulations, shortage of talented people, and necessity to invest in new technologies.
In this regard, a larger firm can afford:
- using modern techniques
- a workflow enriched with artificial intelligence
- learning and training of their employees
- compliance and protecting information from cybercrime
- various consulting services
- defining opportunities in different regions
This, however, does not mean that every CPA firm is to merge with or acquire another organization.
It means that organizations have to think carefully about how they are going to expand today. Some will merge, while others will focus on hiring professionals, using new technologies, and establishing partnerships with other organizations.
What this means for US CPA firms
The deal between Grant Thornton and CBIZ can push small to medium-size accounting companies to think further about their own development in the long run.
Some important questions might emerge such as:
1. Will larger accounting companies bring more competition?
2. Will clients expect faster reporting and an extended range of services?
3. Will technology be more significant for accounting firms?
4. Will companies need more qualified specialists to handle the increased amount of work?
These are fundamental questions.
However, the answer isn’t always in going bigger or building all capabilities internally.
Many accounting companies already have some great advantages in such areas as strong relationships with clients, unique experience, knowledge of the local market, personal attitude to clients and ability to act quickly.
The key lies in maintaining the mentioned capabilities and building up some capacity.
For example, as the accounting firm attracts more clients, it should be ready to deal with more work.
Instead of hiring a big internal team to accomplish one and the same task repeatedly, the organization might think about flexible outsourced assistance when it comes to bookkeeping, accounting reconciliation, tax preparation, payroll, financial reporting, and other typical jobs.
This will allow them to spend more time on:
- Building stronger client relationships
- Providing advisory services
- Growing the business
- Managing complex accounting and tax work
- Making important business decisions
- Delivering higher-value services
The purpose is not to replace professional expertise. It is to support the team by managing routine work efficiently, so experienced professionals can focus on the areas where their knowledge and expertise create the most value.
The real challenge is not winning more work
Envision a CPA firm that has just concluded a triumphant year. Customer demand is on the rise. Fresh contracts keep flowing in. The firm is providing new services. The profit is improving.
From the outside, everything seems as it should be. But then you start witnessing increasing workload.
Bookkeeping duties increase each month. More accounts need to be reconciled. Tax deadlines are looming. Clients’ requests are growing in number. It becomes necessary for the internal staff to start spending more time dealing with routine matters rather than working on advisory projects.
The firm has achieved growth but it hasn’t expanded its operations at the same pace. This is where the growth becomes problematic. A firm may gain clients but face challenges if the necessary processes, resources, and workflows are not capable of taking the additional workload.
The question is not only “How do we grow?”
The question is also “How do we make growth possible without overcomplicating the operations?”
The answer might lie in better technology, standardized processes, internal hiring, automation, or engaging somebody from outside. In a lot of cases, a combination of some of these options is a winning solution.
Scale does not always mean building everything internally
It is common to think of the accounting profession as one that relies on expertise, accuracy, integrity, and professional judgment. All of these factors will continue to be significant. However, the approach to work has changed.
In today’s world, a modern CPA firm does not need to build every competency from scratch within its own organization. Strategic support can enable a firm to create more capacity while maintaining control and quality of services.
Outsourced accounting support can play an important role in helping a firm.
By using the right support model, a firm can take care of ongoing and process-oriented work while its employees focus on more important activities.
The need for support in specific areas depends on a firm’s circumstances and could include:
• Accounting
• Account reconciliation
• Financial reporting
• Tax return preparation
• Payroll services
• Sales tax reporting
• Audit services
• Client Accounting Services
• Financial planning and analysis
It is essential to note that outsourcing is not a universal panacea, and it is not just a decision made with the purpose of saving money.
If done correctly, outsourcing may become a capacity approach that allows a firm to deal with changing workloads, facilitate ongoing operations, and lay the foundation for growth.

The future of accounting will be more connected
In the future, the accounting firm is likely to have a completely different appearance. Technologies will keep on automating everyday tasks. Artificial Intelligence will modify the way how data is treated. Customers will demand insights that are faster and advice that are more active.
The companies will still pursue mergers, acquisitions, partnerships and new ways of providing services. However, technologies are not going to solve all problems. Companies need professional people, dependable procedures, quality control, and an ability to handle changing workloads.
Companies with the ability to adapt to future tasks will be the ones that keep the combination of:
Personnel + Technologies + Effective Processes + Flexible Capacity.
This combination will help companies remain flexible and decrease the burden on their in-house personnel.
The CBIZ and Grant Thornton deal is a bright example of how the companies are going to achieve bigger size. However, growth does not have the same shape for each company.
For instance, one regional CPA firm may develop through specialization.
- A boutique company may grow due to increasing effectiveness of their advisory service.
- A mid-size company is going to invest in automation.
- Another company is going to employ external service to increase their operational capacity.
- Different strategies can lead to the same outcome:
- A more capable, resilient, and scalable accounting practice.
Final Thoughts: Scale requires more than size
The upcoming acquisition of CBIZ by Grant Thornton for $5 billion can be classified as one of the most significant events in the realm of accounting in the year 2026. The deal illustrates the growing importance of scale, broad capabilities, technological investments, and strength of operations. It also indicates that the accounting industry in the United States is undergoing changes through modern business models and strategies.
The moral of this story for CPA firms, however, is not that every company should become larger by means of buying others’ businesses. Instead, it teaches firms that they first need to think how they will develop their capacity for tomorrow.
The development of capacity can take place through talents, technologies, processes, specialization, strategic partnership, or outsourcing.
