Buying a Veterinary Practice: Financial Due Diligence Checklist

You've found a practice you like. The broker says it's priced at 85% of collections. The seller says it runs itself. Before you sign anything, you need to see behind that story — and most first-time vet buyers don't know what to look for. This guide covers the financial due diligence that separates a good acquisition from a costly mistake.

Phase 1: Documents to Request

A serious seller should provide all of this within 5-7 business days once you have a signed letter of intent and NDA in place. If they're evasive about any category, that's your first red flag.

Financial records

• 3 years of federal tax returns (business entity return, and personal if sole proprietorship)
• 3 years of profit & loss statements and balance sheets — compare these to the tax returns. Gaps between P&L income and taxable income need explaining.
• Current accounts receivable aging report — how much is owed, and for how long?
• 12 months of bank statements — confirms revenue actually deposited matches reported revenue
• Outstanding loans and liens — equipment notes, SBA loans with transfer restrictions, UCC filings

Production and operational records

• Production reports by doctor, last 2 years — what does each DVM individually produce? If the selling vet drives 70%+ of production, their departure is a revenue cliff.
• Active client count (last 18 months) — how many unique clients? Is the number growing or shrinking?
• New client acquisition rate by month — flat or growing new clients is a good sign; declining new clients is a warning
• Appointment availability and waitlist — a 3-4 week wait means demand exceeds capacity (upside); minimal wait in a saturated market means different
• Staff roster with compensation, tenure, and FTE status
• Any existing employment contracts or non-solicitation agreements

Legal and facility records

• Lease agreement (if rented): term remaining, renewal options, rent escalation clauses, landlord consent to assignment
• Equipment list with purchase dates and maintenance history
• Licensing: state veterinary practice license, DEA registration, state controlled-substance license
• Any pending or past regulatory actions (state board, OSHA, DEA)
• Existing contracts: referral relationships, cremation providers, lab service agreements

Phase 2: Financial Analysis — How to Read What You Get

Normalize EBITDA (the number that drives valuation)

Reported net income on the P&L is not what a buyer should pay for. You need adjusted EBITDA — earnings before interest, taxes, depreciation, and amortization, plus add-backs for owner-specific items that won't persist under your ownership.

Common add-backs that increase adjusted EBITDA:

• Owner's above-market compensation (if paying themselves $400K when a replacement DVM costs $150K, add back the difference)
• Owner's personal vehicle run through the practice
• Owner's family members on payroll not doing real work
• One-time legal or consulting expenses
• Depreciation and amortization (non-cash)
• Interest on existing debt you won't assume

Common deductions that decrease adjusted EBITDA:

• If owner was paying themselves below-market, add a market-rate replacement DVM cost
• Deferred maintenance you'll need to fund in year 1
• Any unusually low rent from a related-party landlord that will reset at market rate under your lease

Production per DVM benchmark

A full-time small-animal DVM typically generates $600K–$900K in annual gross revenue¹. Large-animal and mixed practices vary more due to mobile costs and seasonal concentration. If production per doctor is significantly below these ranges, understand why: is the market saturated? Is the vet only working part-time? Is the fee schedule 10 years out of date?

Overhead percentage

Industry overhead for companion-animal practices averages 70–80% of gross revenue¹. Overhead includes all expenses except the owner's compensation and debt service. Below 70% suggests tight operations or a practice that hasn't invested appropriately in staff. Above 85% means thin margins that will pressure your cash flow after debt service is added.

Accounts receivable health

Most vet practices are primarily cash or payment-plan businesses — client AR should be minimal. If you see large AR balances aging past 60 days, find out why. Corporate-billed accounts (insurance, government contracts) can carry legitimate AR; client balances over 90 days are usually uncollectible.

Phase 3: Is the Asking Price Reasonable?

Private vet practice sales typically price at 70–95% of trailing 12-month gross collections or 4–6× adjusted EBITDA, depending on practice type, growth rate, and geography². A practice with strong growth, low doctor-dependency, and multiple vets on staff commands the top of that range. An owner-dependent single-vet practice with flat revenue prices at the bottom.

Quick sanity check:

• Ask for trailing 12-month gross revenue and compute 70%, 80%, 90% of that number
• Ask for trailing 12-month adjusted EBITDA (they should provide this or you should calculate it) and multiply by 4, 5, 6
• The asking price should sit somewhere in the overlap of both ranges for a fairly priced deal
• A significant premium over both ranges needs a specific growth story to justify it

Use the practice acquisition ROI calculator to model whether the asking price, at your projected debt service, produces adequate return versus staying as an associate.

Phase 4: SBA 7(a) Loan Qualification

Most vet practice acquisitions under $5M are financed with an SBA 7(a) loan — the workhorse of small-business acquisition lending. Key terms:

• Maximum loan amount: $5 million³
• Typical down payment: 10–20% of purchase price (higher for thin-equity practices or lower credit scores)
• Term: Up to 10 years for practice acquisitions (up to 25 years if real estate is included)
• Collateral: SBA requires a lien on all business assets; may require personal real estate if practice assets are insufficient
• Personal guarantee: Required for all owners with 20%+ equity
• Debt service coverage: Most SBA lenders want 1.25× coverage — meaning if your annual debt payments are $120K, the practice needs to produce at least $150K in adjusted EBITDA

Specialized vet practice lenders — including Live Oak Bank, Bank of America's healthcare lending division, and some community banks — understand vet practice cash flows better than generalist SBA lenders. They're more likely to understand that a single-DVM practice is riskier than a multi-vet one and price their terms accordingly⁴. Apply with a vet-specialist lender first.

Phase 5: Red Flags That Should Slow You Down

These don't always mean walk away — but each one requires an explanation you can verify:

• Owner drives 70%+ of production. When they leave, that production doesn't automatically transfer to you. New clients may leave too. Factor a revenue haircut of 15–25% in year 1 for high owner-dependence practices.
• Client count declining year-over-year. Flat is okay if the practice has raised fees (revenue up, clients flat). Declining client count with flat revenue usually means fee increases masking attrition — not a healthy sign.
• P&L and tax returns don't match. Some discrepancy is normal (depreciation timing, etc.). Large unexplained gaps could mean unreported income (good for you as a buyer if real) or expenses being masked (not good). Either way, get a vet-focused CPA to reconcile them.
• Short lease remaining with no renewal option secured. A practice with 18 months left on a lease and a landlord who won't commit to renewal is a practice you might buy and then lose its location. Lease assignability and renewal terms are non-negotiable.
• Equipment is 10–15 years old across the board. Budget $150K–$400K for major equipment refresh over the first 3 years, and factor that into your ROI model. Don't let a low purchase price mask a hidden capex requirement.
• Seller received and declined a corporate offer. Ask why. A seller who passed on an 11× EBITDA corporate offer to sell to you at 5× either has specific reasons you should understand (post-sale employment, locality ties, speed of close) or the corporate due diligence found something the broker hasn't told you.
• High staff turnover in the last 2 years. Get the staff roster with tenure dates. If you see a pattern of 1–2 year tenures, the work environment is the problem and it stays after the ownership changes.

Phase 6: Transition Planning

Even a financially healthy practice can stumble post-acquisition if the seller exits abruptly. Key questions:

• Transition period: Most SBA lenders require a 30–90 day seller transition. Negotiate 60–90 days with graduated reduction in the seller's clinical days — enough for you to build client relationships.
• Non-compete: A seller non-compete in the same specialty within 5–10 miles for 3–5 years is standard and enforceable in most states. Get this in the purchase agreement, not just the employment agreement.
• Key employees: Identify who the practice couldn't operate without and determine their compensation and retention plans before you close.
• Client communication: Who sends the "new ownership" letter? The seller introducing you is more credible than you introducing yourself. Plan this in the purchase agreement.

What a Vet-Focused Advisor Does for Buyers

A fee-only financial advisor who specializes in veterinary practice transactions adds value at three points in a purchase:

1. Pre-LOI analysis: Before you make an offer, a specialist can review the CIM (confidential information memorandum) and tell you whether the normalized EBITDA is realistic and whether the pricing is defensible. Catches overpriced deals before you're emotionally invested.
2. Post-LOI financial modeling: Builds a 5–10 year cash flow model under different revenue growth scenarios. How many years to break even versus staying as an associate? What does your retirement picture look like if you own this practice vs. investing the down payment instead? Use the practice acquisition calculator for a quick version of this analysis.
3. Post-close tax structure: The day you own a practice, entity structure decisions (S-corp election, retirement plan setup) have immediate financial impact. A specialist advisor gets you into the right structure before the first payroll instead of fixing it in year 3. See the S-corp election guide for vets.
