Due Diligence When Selling a Veterinary Practice

Due diligence is where a buyer tests whether the business they thought they were buying is the business that actually exists. For a veterinary practice, the process is usually more sector-specific than sellers expect.

A buyer will still review accounts, tax, employment records, contracts, and legal structure. But the questions that really affect price are the ones that show whether the revenue is durable, whether risk has been controlled, and whether the business can transfer cleanly after completion.

Why does sector-specific due diligence matter?

Generic due diligence asks whether the numbers are accurate. Sector-specific due diligence asks whether the business model is robust.

For a veterinary practice, buyers will pay particular attention to clinical records, vet and nurse retention, out-of-hours arrangements, pet health plans, equipment, stock, property terms, and complaints history. These areas influence valuation because they tell the buyer whether earnings are repeatable or fragile.

If the evidence is clean, diligence can reinforce the original offer. If the evidence is weak, the buyer may reduce price, ask for stronger warranties, require an indemnity, increase deferred consideration, or extend exclusivity while they investigate.

What documents should be ready?

Before signing heads of terms, prepare a data room that makes the buyer's work straightforward. At minimum, include:

Three years of statutory accounts
Monthly management accounts and current-year trading
Revenue analysis by customer, service line, contract, or site
Gross margin and EBITDA bridge
Key customer or client contracts
Supplier and subcontractor agreements
Staff list, contracts, pay details, and any disputes
Insurance policies and claims history
Property leases, licences, or asset finance documents
Compliance records specific to the sector
Complaints, disputes, or regulatory correspondence
A clear explanation of owner involvement and transition plan

The aim is not to create a huge data room. The aim is to create a useful one. Buyers become nervous when basic information is missing, inconsistent, or produced only after repeated requests.

What financial checks will buyers run?

Financial due diligence will test whether reported profit is maintainable. Expect buyers to examine revenue recognition, one-off income, owner costs, exceptional expenses, working capital, debt-like items, and the normal level of cash needed to run the business.

For a veterinary practice, the financial review will usually focus on whether margins are stable and whether recent performance reflects underlying trading rather than timing, temporary cost savings, or unusually strong one-off work.

Prepare a simple EBITDA bridge before the process starts. If you are adding back costs, make sure each adjustment is evidenced and commercially reasonable. Aggressive add-backs are one of the fastest ways to lose buyer trust.

What operational checks will buyers run?

Operational diligence asks whether the business will keep working after completion. Buyers will look at who holds key relationships, which people are essential, how work is delivered, and whether the systems can scale.

The biggest operational red flag is owner dependency. If the owner prices work, manages key clients, resolves technical problems, approves every hire, and controls the finances, the buyer is not acquiring a business so much as negotiating a handover of personal goodwill.

Reducing that dependency before sale is often worth more than trying to negotiate around it afterwards.

What are common red flags?

The issues that most often damage a deal are:

Management accounts that do not reconcile cleanly
Customer or contract concentration without a credible explanation
Missing signed contracts or undocumented variations
Informal employment, bonus, or commission arrangements
Compliance records that are incomplete or out of date
Unresolved disputes, complaints, or claims
Heavy dependence on the founder or one senior employee
Poor data quality in the CRM, finance system, or operational software
A data room assembled in a hurry after exclusivity begins

None of these automatically kills a deal. But each one gives the buyer a reason to revisit price or structure.

How should you prepare?

Start with a pre-sale diligence review. Pick the documents a buyer would ask for and test whether you can produce them quickly, accurately, and consistently.

Then work through the following:

Reconcile revenue schedules to management accounts.
Review major contracts and identify change-of-control or termination risks.
Clean up employment records and any informal arrangements.
Resolve known compliance gaps before buyer outreach.
Document management responsibilities below the owner.
Prepare a balanced explanation of risks rather than hoping they are not noticed.
Build the data room before exclusivity, not during it.

Good diligence preparation does not just avoid problems. It helps the buyer move faster and gives them fewer reasons to chip the deal late in the process.

FAQ

How long does due diligence take when selling a veterinary practice? For a prepared seller, six to ten weeks is common. It can take longer where records are incomplete, compliance questions are unresolved, or the buyer needs specialist advisers.

Can diligence reduce the price after heads of terms? Yes. Heads of terms are usually subject to diligence. If the buyer finds risks that were not reflected in the offer, they may seek a price reduction, more deferred consideration, or specific protections in the SPA.

Should I disclose problems before the buyer finds them? Yes. Controlled disclosure is almost always better than surprise discovery. Buyers can price known issues; they lose confidence when they feel the seller did not understand or disclose them.
