Manage the vendor’s role after settlement through clear availability, agreed requests and decision-making boundaries, with a planned transfer of knowledge before support ends.
The outgoing owner may know the answer to almost every question in the practice. That knowledge is valuable, especially when a client calls about an old arrangement or a staff member needs the history behind an unfinished job.
The challenge is to use that help while establishing confidence in your own leadership.
For an Australian accounting-practice buyer, a useful arrangement makes the vendor’s contribution specific. People should understand when help is available, how to request it and who now makes decisions. Settlement changes ownership, while the handover gives the team a practical way to work through that change.
The vendor’s role after settlement: the short answer
Translate the agreed support into activities, hours and review dates.
Use a clear channel for requests, with different arrangements for urgent matters.
Explain who now makes management and service decisions.
Plan client contact and staff communication together with the vendor.
Transfer knowledge early, prepare for absence and review access as responsibilities reduce.
Start with the support you have actually agreed
Your working plan should begin with the documented vendor handover. Check the duration, expected hours, activities and payment arrangements with your solicitor where interpretation is needed.
A broad promise to ‘help as required’ is difficult to schedule and may mean different things to buyer and vendor.
The Australian Government’s business-sale guidance identifies handover training among matters to negotiate and handover details among terms in the sale agreement. Your solicitor should address how the particular obligations work. The daily schedule then turns those agreed terms into introductions, briefings and answers the incoming team can use.
Ask about availability during the periods that matter to this practice.
An owner who is available on Mondays may not be available for a difficult client meeting on Thursday. Record planned absences and the support arrangements around them, rather than assuming a fixed number of hours means access whenever you need it.
Give requests a clear route
Without a shared process, the vendor can receive scattered calls, messages and corridor questions from several people. The same issue may be raised twice, while an important unanswered question disappears into someone’s personal inbox.
A simple request list makes the available support easier to use.
Agree who can request assistance and how it will be organised. A practice manager could collect routine questions for scheduled sessions, while time-sensitive matters follow an agreed escalation route.
Record the client or task, the specific question, the person waiting for the answer and the date it is needed.
For unfinished work and related billing matters, clarify whether you need historical context, technical input or completion of an agreed task. Those are different requests.
Explain the distinction so the vendor knows what is expected and the team knows who remains responsible for progressing the job.
Make management and professional responsibility clear
The vendor may be helping with client relationships, technical review or training. Define what authority accompanies each activity and which decisions need your approval.
Staff should know who decides pricing, work allocation, leave arrangements and proposed changes, within the actual management and employment arrangements.
If staff receive different instructions from you and the vendor, address the conflict privately and promptly. Explain the agreed decision to the team afterwards. The aim is to make responsibilities understandable while respecting the vendor’s experience and avoiding an unnecessary public contest over authority.
The Tax Practitioners Board’s supervision and quality-management guidance explains the importance of directing, overseeing and checking services provided on a practitioner’s behalf. Confirm the applicable professional responsibilities with your advisers. Vendor availability should not be treated as a substitute for the acquiring practice’s own competent service and supervision arrangements.
Your earlier review of the staff structure helps identify who can take on particular responsibilities.
Give those people time, training and a route for difficult questions. A title change alone does not transfer the knowledge needed to perform the role.
Agree how the vendor will speak with clients
A familiar voice can help clients feel comfortable with the transition. Agree which introductions will be joint, which conversations the vendor will lead and when the incoming relationship manager will follow up. Explain who clients should contact afterwards, including when the vendor remains involved for a limited purpose.
Where relationships depend heavily on the owner, the vendor’s reassurance may be especially useful.
Yet the incoming manager needs to participate and begin answering questions. A conversation that sends every future concern back to the outgoing owner can leave the original dependency intact.
Agree how to handle direct calls the vendor receives later. They might direct the client to the nominated contact, or involve that person in a response where appropriate.
Avoid commitments about fees, timing or future services that the current team has not reviewed and cannot reliably support.
Transfer knowledge while help is available
Use planned sessions to capture important client information, recurring procedures and unresolved matters. Ask the incoming staff member to explain the next step back in their own words, or demonstrate the process where suitable. That makes gaps visible while the vendor can still help resolve them.
Prepare for absence as well as the planned endpoint.
If the vendor becomes unavailable, who can find the relevant record, complete a review or contact the client? Keep essential information in the authorised practice system and arrange suitable support for work the team cannot yet perform independently.
If new work falls outside the agreed assistance, clarify scope, approval and payment before it begins. Discuss significant additional costs with the relevant advisers and reflect them in cash-flow planning.
Your solicitor should address contractual questions, because a helpful conversation does not by itself settle the terms of an expanded engagement.
Review access as the role changes
System access should support the actual work the vendor is authorised to perform. Your technology review should now connect with named accounts, appropriate permissions and a review date.
Ask the technology adviser to check administrator rights, shared accounts and recovery arrangements as responsibilities move.
Australian Signals Directorate guidance on restricting administrative privileges recommends regularly revalidating the need for privileged access, including when duties change or people leave. You should apply that principle proportionately and avoid leaving broad access in place simply because the vendor previously owned the firm.
The TPB’s client-confidentiality guidance also matters where information is disclosed to third parties. Ask your advisers how permission, confidentiality and records requirements apply to the vendor’s continuing engagement. Ending access should follow a planned process that preserves required records and authorised service continuity.
An illustrative example: scheduled help becomes transferable knowledge
Suppose a vendor provides agreed support for a limited handover period. The buyer schedules weekly question sessions and joint introductions. Routine requests go through the practice manager, while urgent matters follow an agreed contact route. This is an illustration, not a recommended duration or contractual arrangement.
At each review, the team identifies unanswered questions and responsibilities still relying on the vendor. Before support ends, the buyer checks whether client contacts, technical supervision and system permissions reflect the next phase.
Any extra assistance is discussed separately rather than assumed to continue indefinitely.
Frequently asked questions
Can the vendor continue managing staff?
That depends on the agreed role and management arrangements. Make responsibilities clear to staff and obtain advice on the legal and employment implications of the particular engagement.
What if the vendor is unavailable unexpectedly?
Use the agreed contingency plan and assign someone to assess urgent work. Obtain appropriate support where needed and ask your solicitor about contractual issues rather than assuming availability can be compelled.
Should all client calls go through the vendor initially?
Choose arrangements that support continuity and introduce the incoming contact. If every conversation remains with the vendor, clients may have little opportunity to develop confidence in the new team.
Does additional assistance have to be free?
Check the documented scope and payment terms with your solicitor where needed. Agree any additional work and cost before relying on support outside that arrangement.
When should vendor access end?
Align permissions with current authorised responsibilities and review them as support reduces. Your technology and legal advisers should help manage access, required records and confidentiality appropriately.
Leave the team able to act
A productive vendor arrangement leaves people increasingly able to serve clients and make appropriate decisions themselves. Review progress against the agreed endpoint, address gaps early and keep any continuing support specific. The value of the handover lies in what the practice can confidently do as the vendor steps back.
