You spent weeks and real money landing a strong new accountant. The first ninety days decide whether that investment compounds or evaporates. It is not an exaggeration. Structured onboarding has been shown to improve new-hire retention by more than 80 percent, and employees who experience it are markedly more likely to still be with the firm three years later. An onboarding checklist for new accountants is the difference between a hire who becomes a fixture and one who quietly starts taking calls by month six.
Why the first 90 days make or break retention
The early weeks set a new hire’s expectations about what the firm is really like, whether it is organized or chaotic, whether they are supported or abandoned, whether the role matches what they were sold. A rocky start plants doubt that is hard to reverse later, no matter how good the work becomes.
The 30 / 60 / 90 structure
The most reliable CPA firm onboarding plans move through three phases. The first thirty days are for learning, absorbing tools, processes, people, and the firm’s culture. The next thirty shift to contributing, real work on real engagements with tight feedback loops. The final thirty are for executing, moving toward full autonomy and setting the longer-term goals that connect the new hire to where the firm is going.
Get day one right
Day one is disproportionately powerful. Have the workspace, logins, and tools ready and tested before the person arrives. Introduce them to the team and the cross-functional contacts they will depend on. Assign clear ownership for each onboarding task, HR, IT, the hiring manager, a peer buddy, so nothing falls through the cracks in the first, most formative week.
Build in the check-ins
Schedule structured conversations at the 30, 60, and 90-day marks, real reviews of early wins, growth areas, and support needs. These check-ins are among the highest-return actions a firm can take. Firms that run them cut first-year turnover dramatically compared with those that leave the first months to chance — see the true cost of turnover →. They also hand the new hire their first goals, connecting onboarding directly to the ongoing performance rhythm → the firm already runs.
