For many firm owners, preparing for due diligence is the most daunting part of the sale process. It’s where a buyer moves beyond the headline numbers and starts looking under the bonnet of your practice. When well prepared, due diligence builds buyer confidence, protects your agreed price, and keeps the transaction moving smoothly. When poorly prepared, it can lead to delays, renegotiation—or deals falling over entirely.

The good news? With the right preparation, due diligence can be a structured, manageable, and even positive experience.

Below, I outline the key areas buyers will focus on, the information you’ll need to present, and the typical questions you can expect along the way.

1. Client Base Analysis

Your client base is the single most important asset in your accounting practice. Buyers will want to understand not just who your clients are, but how sustainable and transferable those relationships will be post-sale.

Information buyers will request:

• Segmentation of the full client list by service type and fee size
• Top 20 clients by annual fees
• Client demographics and industry mix
• Identification of new clients added in the last 12 months
• Clients lost in the last 12 months and reasons for departure
• Analysis of recurring vs one-off or non-recurring work
• Billing methods (fixed fee, time-based, value pricing)
• Charge rates and fee arrangements

Typical buyer questions:

• How reliant is the practice on its largest clients?
• Are there any clients likely to leave in the short term?
• How sticky are the client relationships without the current owner?
• Are fees appropriately priced and maintainable?

2. Financial Performance & Records

Buyers need confidence that the financial results accurately reflect the true earning capacity of the practice. Clean, consistent, and well-explained financials are essential.

Information buyers will request:

• Profit and loss statements (last 2–3 years)
• Balance sheets and tax returns (typically last 3–5 years)
• Business Activity Statements
• Accounts receivable and payable listings
• Cash receipts and payments reconciled to the accounts
• Work in progress (WIP) and stock, if applicable
• Details of bank loans, overdrafts, or lines of credit

Typical buyer questions:

• Are revenues recurring and predictable?
• Are there any abnormal or one-off items affecting profits?
• How strong is cash flow and debtor management?
• Are profits sustainable under new ownership?

3. Expense Review & Normalisation

One of the most common areas of price renegotiation arises from expenses. Buyers will carefully review costs to understand what will continue, what may change, and what has been understated or deferred.

Information buyers will request:

• Detailed expense breakdowns
• Explanation of owner-specific or discretionary expenses
• Prepaid expenses and accruals
• Maintenance and service agreements
• Advertising and marketing commitments

Typical buyer questions:

• Are all expenses fully reflected in the accounts?
• Has the owner paid any costs through another entity?
• Are there deferred expenses or under-maintained assets?
• What expenses will change once ownership transfers?

4. Staff & Employment Matters

In professional practices, people matter. Buyers want reassurance that key staff will stay and that there are no hidden employment risks.

Information buyers will request:

• Employment contracts and variations
• Roles, tenure, and remuneration details
• Leave entitlements and balances
• Time and payroll records
• Employee policies and manuals
• Any history of disputes, claims, or injuries

Typical buyer questions:

• Who are the key client-facing staff?
• Are employment contracts compliant and transferable?
• What is the risk of staff turnover post-sale?

5. Systems, Infrastructure & Technology

Modern, well-documented systems reduce buyer risk and ease transition. Outdated or undocumented processes can raise red flags.

Information buyers will request:

• Details of accounting, practice management, and workflow systems
• Level of automation and documentation
• Data security and privacy procedures
• Audit work papers (if applicable)

Typical buyer questions:

• How reliant is the practice on the owner’s personal knowledge?
• Can systems scale or integrate into another firm?
• Will additional investment be required post-acquisition?

6. Legal, Contracts & Risk Review

Buyers need to know exactly what they are acquiring—and what risks come with it.

Information buyers will request:

• Client engagement letters
• Staff and contractor agreements
• Partnership or shareholder agreements
• Lease agreements
• Professional indemnity insurance history and claims
• Intellectual property details

Typical buyer questions:

• Are there any unresolved legal or compliance issues?
• Are contracts assignable to a new owner?
• Have there been any PI claims or disputes?

7. Assets & Other Considerations

Even in service-based practices, tangible and intangible assets matter.

Information buyers will request:

• Plant and equipment lists
• Vehicles and fixtures
• Intellectual assets and branding
• Credit history and searches
• Vendor reference checks

Final Thought: Preparation Protects Value

Due diligence is not something to fear—it’s something to prepare for. Practices that invest time in organising their information, addressing weaknesses early, and presenting a clear story are far more likely to achieve a smooth sale at the right price.

If you’re considering selling your accounting or bookkeeping practice, an early conversation can make all the difference. I regularly help firm owners prepare for due diligence well before going to market, ensuring there are no surprises and maximum value is achieved.

If you’d like to understand how ready your practice is for sale, I’d welcome a confidential conversation.

Due Diligence Readiness Checklist

Before taking your practice to market, ask yourself:

• Do I have at least 2–3 years of clean, well-explained financial statements?
• Can I clearly identify recurring vs one-off revenue?
• Is my client base well documented, with limited concentration risk?
• Are client engagement letters, staff contracts, and leases current and assignable?
• Are key staff likely to remain post-sale?
• Are systems, workflows, and pricing structures documented and transferable?
• Have owner-specific or discretionary expenses been identified and normalised?
• Are there any unresolved compliance, legal, or PI insurance issues?

If you’re unsure about any of the above, that’s completely normal—and exactly where early advice adds the most value.

A short conversation now can save months of stress later and protect the value of your life’s work. Reach out for a confidential, no-obligation discussion about your practice and your exit options.
