What Should You Look for in the Client Base of an Accounting Practice?
Updated: Sep 30
The total fee number matters, but the quality of the client base tells you how dependable, concentrated and transferable those fees may be.
A practice can look attractive when you first see the annual fee figure. Stage 1 should go one step further: understand what sits inside those fees before you assume the client base will behave like a single stable asset.
An accounting practice client base should be understood by concentration, recurrence, service mix and relationship ownership—not only by its total annual fees.
You do not need a complete named client register on day one. You do need enough aggregated information to see the shape of the client base and identify the obvious questions for later due diligence.
Accounting practice client base: the short answer
Look at how many clients produce the fees, not just the total annual revenue.
Identify concentration by major client or client group, service type and industry.
Separate recurring work from one-off or irregular revenue.
Ask who owns the client relationships and how dependent they are on the vendor.
Use aggregated or de-identified information early where privacy and confidentiality make named client data inappropriate.
Start with the shape of the fee base
A $1 million practice made up of 500 reasonably diversified clients can present a different commercial profile from a $1 million practice where a small number of family groups account for a large share of fees.
At Stage 1, useful headline data includes the number of clients or client groups, average fees, median or broad fee bands, and the proportion represented by the largest clients.
Client concentration is more than a top-ten list
Concentration should be considered at the economic-group level where appropriate. Several entities may look like separate clients in the practice management system while effectively representing one business family or ownership group.
The question is not simply whether one client is large. It is how much revenue could be affected if one commercial relationship changed after settlement.
Recurring fees and one-off fees should be separated
A buyer should understand how much of the reported revenue is expected to repeat. Annual compliance, bookkeeping and recurring advisory work can behave differently from one-off restructures, special projects or unusually large transactions.
That does not mean non-recurring work has no value. It means the headline fee number should not be treated as automatically recurring without understanding its composition.
Service mix can change the economics
Two practices with similar annual fees can require very different staffing and technical capability if one is heavily weighted to routine compliance and another to bookkeeping, SMSF, audit or higher-touch advisory work.
At this stage, map the broad service mix and identify any area where the buyer may need additional capability, licences, specialists or staff after settlement.
Industry concentration can matter
A client base concentrated in one industry can create both strengths and risks. The practice may have deep expertise and efficient processes, but the revenue can also become more exposed to one sector's economic or regulatory conditions.
The important Stage 1 question is whether the industry mix fits the buyer's strategy and whether any concentration deserves closer investigation.
How transferable are the relationships?
Historical fees belong to the past. The acquisition only works commercially if enough of those client relationships continue after the ownership change.
Ask who normally speaks to the clients, who signs off important work and whether key relationships sit with the vendor or other staff. The people question is explored further in Owner Dependence and Key Staff Risk When Buying an Accounting Practice.
Named client data may not be appropriate at the start
Early analysis can often be done using de-identified or aggregated data. The OAIC's guidance on business sales notes that vendors and prospective purchasers need to consider privacy obligations when personal information is disclosed during due diligence.
Professional accountants also have confidentiality obligations. A buyer should not treat access to a full named client list as an automatic Stage 1 entitlement.
Questions to ask before going further
How many clients or economic client groups generate the annual fees?
What proportion of fees comes from the largest clients or groups?
How much revenue is recurring versus project-based or irregular?
What is the broad service and industry mix?
Who manages the important client relationships and how is the handover expected to work?
Frequently asked questions
Should I insist on a named client list immediately?
Not necessarily. Aggregated or de-identified information may be enough for early screening, particularly where privacy and professional confidentiality need to be managed. Detailed information can be staged as the transaction progresses.
Is a large client automatically a problem?
No. A large client can be valuable and stable. The issue is concentration risk: how much of the practice's revenue and profit would be affected if that relationship changed.
Are recurring compliance fees always better than advisory revenue?
Not automatically. Different revenue streams have different margins, staffing needs, client relationships and growth potential. The buyer should understand the mix rather than assuming one category is inherently superior.
Illustrative decision scenario
Two practices each report $800,000 of annual fees. Practice A has 420 client groups, with its largest group representing 3% of fees. Practice B has 120 client groups, with three groups together representing 28% of fees.
The headline revenue is identical, but the concentration and transition questions are not. This example is illustrative only; the buyer still needs to examine the quality and circumstances of the actual relationships.
A practical early stage client-base check
Prepare a one-page client-base summary showing the number of clients or groups, top concentration bands, recurring versus non-recurring fees, service mix, industry mix and who owns the important relationships.
Highlight what is known and what still needs verification. The purpose is to decide whether the fee base looks sufficiently understandable and transferable to justify deeper due diligence.
Which adviser covers which issue?
An accountant or transaction adviser can help analyse fee composition and profitability. A lawyer can advise on confidentiality arrangements, information-sharing protocols and the sale agreement. Privacy and professional-obligation questions may require specialist advice. A finance broker can explain how client concentration and revenue quality may affect lender assessment.
The buyer remains responsible for deciding whether the client base fits the practice they want to own.
What should you look at next?
Once the client base broadly makes sense, the next question is whether the practice depends too heavily on the vendor or a small number of key people.
Conclusion
Do not reduce the client base to one annual fee number. At Stage 1, understand the concentration, recurrence, service mix and relationship ownership well enough to see where the real risks may sit.
