Accounting-practice 90-day transition plan is a working schedule for transferring relationships and operating responsibilities during the first three months after a sale. Its dates organize management work; they do not create legal disclosure permissions, guarantee client retention, or replace the specific transition obligations in the transaction documents.
What should the first 90 days achieve?
They should establish reliable service ownership, controlled record access, staff responsibilities, billing continuity, and a usable process for unresolved matters. The buyer and seller need visible evidence that responsibilities have moved as intended.
Begin with the seller hub and the executed transition terms. Define the services, client groups, seller availability, buyer leadership, and tasks that must continue through the first operating cycle.
The archived Journal of Accountancy client-retention discussion after a practice sale emphasizes practical transition communication. Use it to frame introductions and responsibility, without treating historical guidance as proof of a current retention percentage.
Choose milestones around actual service events and available capacity. A 90-day calendar can cross filing deadlines, monthly closes, payroll cycles, or quieter periods. The plan should fit those events rather than assume every practice has the same first quarter after closing.
What is the numbered transition working plan?
Add an owner, due date, evidence reference, dependency, and status to each action. The following sequence is adaptable; critical readiness tasks may need completion before closing or earlier than the suggested management period.
- Confirm day-one responsibility. Assign leadership for every active engagement, upcoming deadline, staff question, open client matter, and service escalation.
- Verify approved access. Confirm records, systems, office, billing, and provider arrangements through the reviewed transfer process, without assuming legacy credentials confer authority.
- Brief the team. Explain reporting lines, review responsibilities, client contacts, temporary procedures, and where employees raise uncertain or conflicting instructions.
- Prioritize introductions. Identify relationship-dependent and time-sensitive engagements, schedule permitted introductions, and record the successor contact responsible afterward.
- Reconcile opening work. Review unfinished engagements, receivables, deposits, prepaid fees, and notices against the agreed closing cutoff and responsibility schedules.
- Review days 1–30 delivery. Check deadlines, collections, review queues, staff capacity, client questions, and seller hours. Assign corrective actions with responsible people.
- Clarify engagement scope. Resolve inherited ambiguities and proposed service changes through appropriate client communication and professional review rather than silent assumptions.
- Transfer recurring decisions. Move pricing, staffing, client management, and routine operating choices to the intended leadership according to the agreed roles.
- Review days 31–60 controls. Reconcile billing, system permissions, handoff evidence, exception work, and unresolved files before expanding optional operational changes.
- Validate seller-assistance use. Compare work requested, completed, remaining, and paid against the actual agreement and budget. Resolve excess demands through the agreed process.
- Test independent operation. Confirm the buyer and team can handle essential service, review, client communication, and escalation without relying on unplanned seller availability.
- Close the 90-day review. Record completed transfers, continuing responsibilities, financial differences, client concerns, and a dated plan for remaining work beyond the initial period.
The closing-day checklist supplies the opening evidence. The transition plan should start from that record rather than reconstruct the purchase scope from informal conversations.
Which milestones should be reviewed at 30, 60, and 90 days?
Review observable operating results and handoff evidence, not only whether scheduled meetings occurred. A completed introduction can still leave the successor without essential client context or decision authority.
| Review point | Core evidence | Decision |
|---|---|---|
| Opening week | Deadline ownership, access, contacts, open-matter map | Are immediate duties covered? |
| Day 30 | First service events, collections, queues, introduction log | What threatens the next operating cycle? |
| Day 60 | Recurring workflow, scope issues, exceptions, seller hours | Which handoffs or costs need adjustment? |
| Day 90 | Independent operation, unresolved responsibilities, revised budget | What continues and who owns it? |
These are illustrative management checkpoints, not required legal deadlines. Use more frequent review for a material service interruption, staffing departure, unresolved access issue, or client concern that cannot wait for the next meeting.
How should client communication and data access be coordinated?
Coordinate them through the approved service and disclosure process. Explain who will deliver work and answer questions while preserving clients’ choices and applicable information requirements.
The IRS Section 7216 information center describes restrictions and relevant rules for uses and disclosures of tax return information. Have qualified advisers determine the applicable basis, exceptions, and any required consent for the proposed transfer and subsequent uses.
This plan’s 90-day label is not a presumption of consent for tax records. A management timetable cannot substitute for a permitted disclosure basis or required consent process. Keep records of approved sharing and access responsibilities.
The client-transfer guide explores the broader relationship handoff. In the working plan, record which successor has made contact, what concerns remain, and who owns the next action rather than treating a bulk announcement as a completed transition.
What should the plan do with inherited scope ambiguity?
Make ambiguity visible and resolve it through appropriate review and client communication. Do not assume the buyer’s standard package matches the seller’s historical promises or informal practices.
The Journal of Accountancy’s CAS engagement-letter guidance discusses clear scope and responsibilities. Its principles support reviewing acquired advisory engagements, while each service’s applicable professional and contractual requirements need consideration.
Identify included work, client input duties, review levels, deadlines, and additional services. Record what staff actually do when an engagement falls outside the written description. An exception that occurs every month belongs in the operating model.
The engagement-letter sale guide helps evaluate preparation issues. After closing, assign a reviewer and approved process for scope changes; a transition plan should not silently impose new terms or assume uncommunicated fee increases will fund the acquisition.
How can transition hours exceed the apparent budget?
They can exceed it when meetings, training, client introductions, and exception handling are added without reducing ordinary production work. Measure both seller assistance and buyer-team capacity explicitly.
The following assumptions are illustrative, not an agreed contract, staffing benchmark, or actual outcome. Suppose one employee has 40 weekly hours over 13 weeks, giving 520 scheduled hours. Assume normal production and administration consume 450 hours and transition tasks require 100 more. Planned demand is 550 hours, exceeding capacity by 30.
Forty temporary support hours could cover that gap with a 10-hour modeled buffer if the support can perform the actual tasks. The plan still needs skill fit, timing, supervision, and cost evidence. Generic availability is not a substitute for qualified review capacity.
Separately assume 100 paid seller-assistance hours at a hypothetical $150 rate, costing $15,000. If buyer requests require 120 hours, modeled cost becomes $18,000, a $3,000 difference subject to the actual agreement. These seller hours are separate from the employee schedule; do not count them as interchangeable without identifying the work.
How should retention and collections be measured?
Measure them using agreed definitions and the relevant contract, while keeping operational reporting separate from purchase-price adjustments. A client concern, delayed invoice, and lost engagement are different events.
Track completed work, billings, collections, scope changes, known departures, and responsible client contacts by the permitted review process. Explain period boundaries and related-client groups. Do not assume a first-month collections dip proves a permanent loss without investigating timing and service status.
If the transaction includes a retention adjustment or collection-based provision, follow its actual baseline, exclusions, measurement period, documentation, and dispute process. The operational dashboard can inform review but should not rewrite the signed terms.
For each material concern, record the facts, next action, owner, and date. Use confirmed evidence and clearly labeled scenarios in financial updates. Avoid reporting promised future client fees as collected revenue or presenting an unresolved complaint as an established damages amount.
What should remain after the initial transition period?
A documented responsibility map, current operating budget, resolved transfer evidence, and a dated list of continuing issues should remain. The end of the initial schedule does not automatically end contractual or professional responsibilities.
Review seller assistance remaining under the actual agreement, client questions, record custody, review capacity, system permissions, and any price-measurement process. Assign future dates and decision owners for unfinished work.
The buyer should be able to operate without assumptions about unlimited seller access. The seller should understand the duties that continue and their agreed boundaries. A useful 90-day review makes those facts visible so the parties can finish the handoff and address remaining matters through the documented process.
A few common questions
What else should you know?
Does a 90-day plan authorize tax-file transfers after 90 days?
No. The label is a management timetable, not a legal disclosure permission or presumption of consent. Tax return information requires review of applicable Section 7216 rules, exceptions, and any required consent. Establish the permitted transfer and use process separately, and preserve evidence of approved recipients and access responsibilities.
What should the first month’s review examine?
Examine actual deadlines, work completion, review queues, collections, client questions, staff capacity, access, and seller hours. Compare results with the operating plan and identify material gaps. A completed introduction meeting is not enough if the successor lacks context or authority. Assign corrective actions before the next service cycle is affected.
How should the buyer budget transition labor?
Add introductions, training, meetings, migration, and exception work to ordinary production and administration. Identify qualified capacity by task and timing. Budget seller assistance separately under the actual agreement. If demand exceeds available hours, fund support, change the sequence, or reduce other work rather than relying on unexplained staff availability.
Does the seller’s responsibility automatically end on day 90?
No. Continuing duties depend on the transaction agreements and applicable professional or legal obligations. Review remaining assistance, files, open matters, and any measurement or dispute processes. Record responsible people and dates beyond the initial period. The management review should clarify those boundaries rather than assume a calendar milestone cancels them.
