What to expect in the first 90 days after buying an accounting practice

What should the first 90 days prove?

The first quarter should establish that the buyer can deliver acquired work, communicate with clients, collect fees, and manage exceptions under clear responsibility. It is an illustrative operating period, not a guarantee that every annual relationship will complete a service cycle within three months. Match milestones to the work actually due.

Start with the transition commitments and diligence findings already agreed. Assign continuing owners to clients, deadlines, technical issues, systems, collections, and staff questions. Preserve a current exception list. A transaction announcement is an initial communication; it does not complete the handoff or demonstrate that all critical records and capabilities are available.

The buyer hub connects closing with the operating plan. Use the first 90 days after buying an accounting practice to test that plan and correct facts early. Document changes to scope, staffing, and cash assumptions so decisions respond to observed service results rather than the pressure to declare integration finished.

What needs attention in the opening days?

Confirm the work inventory, imminent deadlines, missing inputs, and responsible people. Verify approved access to essential records, systems, bank and payment functions, client platforms, and communications. Identify who can authorize decisions and who acts as backup. Test access in the real workflow instead of relying on a closing checklist marked credentials received.

The IRS EFIN FAQ states that an EFIN is not transferable. Confirm buyer filing arrangements established before closing and resolve any remaining authorized setup with advisers. Filing readiness is separate from a successful software installation.

Check that contractual transition services are scheduled and that the seller understands the next milestones. Clarify availability, priorities, and escalation. The sole-practitioner handoff guide is useful where knowledge is concentrated in the departing owner. Capture imminent exceptions while the relevant context and people are available.

How should client communications be managed?

Use the agreed message and timing. Give clients a named continuing contact, explain practical service arrangements, and describe decided changes accurately. Prioritize relationships with upcoming work, complexity, or strong seller dependence. Staff should know how to answer ordinary questions and which issues require an authorized leader’s response.

The historical Journal of Accountancy client-retention discussion emphasizes active cooperation and relationship transfer. Schedule purposeful introductions and successor-led follow-up. A client meeting should establish the next task, responsible contact, and any concern requiring action. Track these outcomes instead of counting an announcement email as equivalent to an introduction.

Keep promises consistent with the operating model. If fees, personnel, or platforms may change, avoid guaranteeing permanence. Explain the known plan and how future decisions will be communicated. Confidence depends on dependable service and accurate expectations more than an assurance that nothing will ever change after the transaction.

What should employees know during the first month?

Clarify supervisors, work assignments, decision rights, compensation arrangements, training, and how to raise concerns. Confirm that offers and other agreed arrangements are reflected in actual administration. Employees need workable instructions while continuing client obligations, especially if the buyer’s procedures differ from the acquired firm’s routines.

Use the staff evaluation guide to connect integration with the capability map from diligence. Address missing review or management coverage promptly. Do not assume the person who knows an engagement best can absorb every new administrative task without additional time or support.

Schedule brief operating reviews around exceptions and capacity. Ask where work is waiting, which clients need decisions, and whether training is adequate. Distinguish temporary unfamiliarity from a persistent staffing problem. Fund necessary help rather than using the first quarter to demonstrate savings that the service workload does not support.

What milestones suit days 1 through 90?

Adapt the schedule to acquired deadlines and service cycles. Record which engagements have actually been tested so early conclusions do not imply evidence about work that has not yet come due.

Which cash measures deserve frequent review?

Track bank cash, payroll commitments, collections, aged receivables, upcoming debt and seller payments, transition costs, and integration spending. Compare actual receipts with the forecast by month and client cohort. Explain whether differences reflect timing, reduced scope, discounts, or permanent departures. An annual revenue projection can conceal a short near-term cash calendar.

Maintain a rolling cash forecast with a downside case. Include obligations from advance fees and unfinished acquired work as agreed in closing economics. Update the cost of missing capacity and delayed system savings. The buyer should know what cash is available after upcoming obligations rather than rely on an apparently improving invoice total.

The retention-underwriting guide helps separate changes in relationships from collections timing. Use consistent definitions when reporting to the seller under any purchase adjustment. Preserve support for late receipts and credits so an operating cash issue does not become an avoidable disagreement over the consideration calculation.

How should systems and security change during the quarter?

Follow the migration plan, approved permissions, and acceptance criteria. Preserve required historical context and test workflows before closing temporary environments. Staff should know where authoritative records reside and how errors are corrected. Do not let multiple live copies become competing sources for deadlines, balances, or client instructions.

The IRS written security-plan publication provides a framework for reviewing actual access, service providers, training, and response duties. Update the plan for the buyer’s operation and transition environments. Verify that temporary access has a purpose and end date, and that ongoing administrators and backups are appropriately assigned.

The migration guide explains pilots and reconciliation. Sequence optional platform or reporting improvements after material continuity needs are met. Include training and support costs in the forecast while the new workflows are being tested. A hurried consolidation can obscure whether problems arise from the acquisition or the system change.

What should be done with unresolved diligence findings?

Transfer each actionable finding into the operating tracker with an owner, date, required evidence, and escalation route. Distinguish items that were closing conditions from obligations expressly scheduled after closing. Confirm that the agreed contractual process is used for claims or adjustments rather than treating every operating exception as a purchase dispute.

Review client acceptance, historical notices, work quality, and professional responsibilities with appropriate advisers. A client acquired in the transaction still needs suitable continuing service. Where a material issue emerges, obtain evidence, preserve records, and communicate through authorized channels. The buyer should not repeat historical work unquestioningly because it was included in the purchase.

The IRS Section 7216 information center remains relevant to tax-return-information use and disclosure after closing. Confirm permissions and purposes as additional people or systems receive access. Commercial ownership does not eliminate the need for an appropriate information-handling process across continuing engagements, seller support, and retained historical records.

Which improvements should wait for more evidence?

Delay discretionary changes when their assumptions have not been tested or the team lacks capacity. Pricing, branding, service scope, systems, and leadership changes can interact. Choose an order that preserves accountability and allows results to be understood. Necessary security or professional corrections should be prioritized according to their actual urgency.

Record proposed improvements with expected benefit, required resources, evidence, risks, and review date. A suggestion from the buyer or acquired staff may be valuable without being ready for immediate implementation. Observing a full relevant cycle can help distinguish a persistent workflow weakness from a temporary transition interruption.

What should the 90-day review produce?

1. Confirm which acquired service cycles and relationships have been observed.
2. Reconcile work, collections, staffing, payments and integration expense against assumptions.
3. Resolve or assign material exceptions with deadlines and funded resources.
4. Update the cash forecast, seller-support plan and system-transition milestones.
5. Set the next-cycle objectives without claiming annual retention is already proven.

The review should produce a practical next plan, not a ceremonial declaration of success. Preserve the evidence supporting what works and identify what remains uncertain. The buyer’s first quarter is useful when it improves delivery, reveals cash needs early, and establishes a continuing team able to serve clients as the seller’s role declines.
