When is the Right Time for Accounting Firms to Switch Payroll Providers?
April 24th, 2025 | 4 min. read

Is there really ever a “perfect” time to switch payroll providers when you’re running an accounting firm? With tax deadlines, quarterly reports, staffing challenges, and client expectations constantly on your mind, carving out time for a system change can feel overwhelming and impossible.
Managing payroll services for your accounting clients can be challenging, costly, and resource-intensive. Between constantly changing regulations, managing the technology required, and pulling your team away from client work, many firms are fearful of adding payroll and find themselves questioning the ROI.
But what if you could find an affordable solution and pinpoint a transition window that keeps things running smoothly without overloading your team?

Timing Considerations for Accounting Firms
While there’s no one-size-fits-all answer, we’ve found that summer offers unique advantages for accounting firms considering a switch. But before we dive into why summer works so well, let’s acknowledge the key timing factors every accounting firm must consider:
Why Tax Season Makes Transitions Challenging
The period from January through April represents the most demanding time for most accounting firms. If your senior accountant or tax manager is going to be championing this conversion, you probably don't want to do this in February. That seems like a bad idea.
At Whirks, we understand that attempting to implement a new payroll system during your busiest season would create unnecessary stress and complexity when resources are already stretched thin.
How Year-End Deadlines Complicate Implementation
While starting a new system on January 1 might seem logical from a calendar perspective, year-end brings its own challenges. Your clients rely on year-end reports to be accurate and on time. Adding a system change to this busy season increases the risk of errors or missed deadlines.
Why You Need to Consider Your Team’s Bandwidth
The most successful transitions occur when your implementation team has adequate time and mental bandwidth to learn new systems, processes, and procedures without feeling rushed or overwhelmed.
What Your Clients Expect During System Transitions
Your clients expect uninterrupted, accurate service regardless of your internal changes. Timing this switch during periods when they’re less likely to have urgent payroll needs will improve overall satisfaction.
Why Summer Is Ideal for Payroll Transitions
After years of helping accounting firms transition to our platform, we’ve found that summer provides the optimal window for several compelling reasons:
1. Post-Tax Season Breathing Room
The biggest window we’ve seen consistently is right after tax season. Summer is typically a time when accounting firms are trying to make changes.
The May through August period represents a natural decompression time for most firms. With tax deadlines behind you, your team can approach this new project with clearer minds and less pressure.
2. Staff Availability
Summer often means more flexible scheduling, with team members rotating through vacation time rather than everyone being simultaneously focused on tax deadlines. This creates space for dedicated training and implementation without pulling resources from urgent client work.
3. Time to Prepare Before Year-End
Starting your transition in summer gives you several months to fully implement the new system before year-end processing begins. This timing ensures you’re comfortable with the platform well before W-2 season arrives.
4. Client Receptiveness
Many businesses experience slightly slower activity during summer months, making them more receptive to administrative changes during this time. They’ll have more bandwidth to review and approve new paperwork and forms, or learn new systems and processes.
How to Prepare for a Summer Transition
If you’re considering a summer switch to the Whirks Network Partner Program, here are some key preparation steps to take in the months leading up to your transition:
Planning Your Initial Assessment and Timeline
Start the conversation about your needs and goals at the end of tax season or right after. This allows for thorough discovery and planning without yet implementing changes.
We know from running our own firm that the decision-making process is typically pretty slow. Accountants do a great job of thinking through all the “ifs” and “buts,” so that can sometimes slow down the decision-making process.
Starting these preliminary conversations in spring ensures you have all the information you need to launch in the summer months.
Identifying Your Implementation Champion
Identify who will champion the implementation within your firm. Who has the time and energy to lead this project without competing demands?
While post-tax season is usually the ideal time, it really depends on who champions the transition. For example, if you already have some payroll people segmented out that don't touch tax work, early in the year could be a great time to begin this process.
For most accounting firms, however, summer provides the best opportunity for key team members to focus on implementation without competing priorities.
Developing Your Client Communication Strategy
Develop a clear plan for introducing clients to the upcoming changes. This doesn't mean announcing specific conversion dates immediately, but rather preparing your messaging about the benefits and timeline.
In other words, plan how you’ll reassure clients that their payroll will continue smoothly and focus on the “why” behind the switch.
Creating a Realistic Implementation Schedule
Work backward from your ideal full implementation date to create a realistic timeline. With Whirks, we recommend planning for:
- Initial training and setup: 2-4 weeks
- First client conversions: Beginning in weeks 3-4
- 80% of clients converted: Within 90 days
Making a Summer Transition Successful
As you consider the timing of switching your payroll provider, think carefully about your firm’s unique rhythm and requirements. Choosing the right timing for your transition is key. You want a window that minimizes disruption while giving your team enough breathing room to learn and adapt comfortably.
While summer works best for most accounting firms, providing that sweet spot between tax season and year-end preparations, your specific circumstances might suggest a different window.
Now is the time to begin exploratory conversations, even if you determine your implementation is months away. This preparation period ensures you have all the information you need to make confident decisions and provide a seamless experience for your team and clients.
