Dental Practice Buyside Pre-Sale Checklist: A Due Diligence Preparation Guide for DSO Transactions

If you are considering selling your dental practice to a DSO or private equity-backed buyer, preparation is the single most important factor determining how much you leave on the table — and how smoothly the transaction closes. Unrepresented sellers routinely leave 20–40% of deal value uncaptured. Sellers who are unprepared for due diligence create delays, concessions, and indemnification exposure that erode both valuation and close certainty.

This checklist — developed by Viturtal Consulting for dental practice owners and their advisors — covers the eight due diligence areas that buyers scrutinize most closely in DSO transactions. Use it to self-assess your readiness, identify gaps, and address them before the letter of intent stage.

How to use this checklist

Items are color-coded by priority:

Red — highest scrutiny and deal-breaker territory. Gaps here can kill a deal or trigger significant purchase price adjustments.

Amber — high priority with direct valuation impact. Weaknesses here depress multiples or create earnout risk.

Teal — organizational and strategic items. Important for a smooth close and post-acquisition integration.

1. Financial Documentation

Financial documentation is where buyers start and where most deals encounter their first surprises. PE buyers will recast your EBITDA using their own methodology — know your add-backs before they do, or you will be negotiating on their terms.

Key items: three years of tax returns (business and personal), three years of CPA-prepared profit and loss statements, current year-to-date P&L and balance sheet, accounts receivable aging segmented by payer versus guarantor (AR over 90 days will be flagged as a collection quality concern), fee schedule benchmarked against peer and UCR comparisons, documentation of all owner personal expenses run through the practice, reconciliation of outstanding equipment and facility loans, and verification of no outstanding IRS liens, payroll tax issues, or state tax delinquencies.

2. Production and Revenue Quality

Buyers evaluate revenue quality as carefully as revenue volume. A practice producing $2M with heavy Medicaid exposure and single-provider concentration is worth significantly less than a practice producing $2M with a diversified payer mix and multiple productive providers.

Key items: trailing 12-month production report by provider and procedure code, hygiene production as a percentage of total (buyers target 30%+), payer mix documented by type (PPO, HMO, Medicaid, fee-for-service — heavy Medicaid or HMO exposure depresses valuation multiples), new patient count per month for the trailing 12 months, active patient count seen in the last 18 months, identification of single-provider concentration risk (if you are the primary producer, expect a longer earnout), and recall and recare rate documentation.

3. Legal and Compliance

Legal and compliance gaps create indemnification exposure — the kind that shows up as purchase price holdbacks, escrow requirements, or renegotiated terms after the LOI. PE buyers will run a HIPAA audit; gaps discovered in due diligence create leverage that sophisticated buyers will use.

Key items: dental license active and in good standing with no board actions, current DEA registration, malpractice claims history (request a loss run from your carrier), outstanding or threatened litigation, HIPAA compliance documentation (policies, training records, BAAs with vendors), OSHA compliance (safety manual, bloodborne pathogen training, hazard communication logs), state dental board investigation history including resolved matters, and corporate structure documentation (PC vs. LLC) with confirmation of compliance with your state's DSO ownership rules.

4. Facility and Lease

Lease terms are frequently a deal-limiting constraint that sellers discover too late. PE buyers typically require 7–10 years of remaining lease term or options. A lease with two years remaining and no renewal option is a significant obstacle to closing — and one that takes months to resolve.

Key items: lease with remaining term, renewal options, and assignment clause confirmed, landlord relationship and likelihood of assignment consent assessed, facility documentation (square footage, operatory count, utilization rate), equipment inventory with age, condition, and maintenance records, deferred maintenance and capex needs identified and quantified (buyers will discount for these), and confirmation of outright ownership or documented financing obligations for all major equipment.

5. Human Resources and Staffing

HR and staffing issues — particularly associate classification and employment documentation gaps — are among the most common sources of post-LOI renegotiation. In many states, 1099 associate classification is a compliance red flag that creates liability exposure buyers will price into the deal.

Key items: org chart with tenure, compensation, and employment status (W-2 vs. 1099), proper classification of associate dentists confirmed, employee handbook and all employment agreements, non-competes, and offer letters reviewed, benefits documentation (health insurance, retirement plan, PTO), key person risk assessment (which staff would follow you vs. stay), and confirmation of no open EEOC complaints, wage claims, or workers' compensation litigation.

6. Technology and Systems

Technology documentation is often an afterthought for sellers — but buyers will benchmark your digital presence, flag analog equipment as capital expenditure requirements, and scrutinize software license transferability before close.

Key items: practice management software documented with confirmation of ownership or transferable license, digital radiography system confirmed (analog X-rays are a capital expenditure flag), imaging software documented (CBCT, Panoramic, intraoral camera), online review profile confirmed and benchmarked (Google, Yelp, Healthgrades — buyers will compare you to peers), and website ownership and marketing contracts with termination clauses reviewed.

7. Contracts and Third-Party Agreements

Change-of-control clauses in vendor and software contracts are frequently overlooked. SaaS contracts in particular often contain change-of-control provisions that require vendor consent or trigger automatic termination — a material issue when a buyer is acquiring your practice management platform subscription along with your practice.

Key items: all insurance network participation contracts listed and confirmed as assignable, vendor contracts reviewed for assignment or termination provisions, specialist referral relationships and formal referral agreements documented, all software and subscription services listed (SaaS contracts often have change-of-control clauses), and no exclusivity or non-compete obligations owed to other parties confirmed.

8. Deal Structure and Personal Readiness

The deal structure section is where sellers most often negotiate against themselves. Most PE-backed DSOs will require a rollover equity component — typically 10–30% of deal value rolled into the acquiring entity. Understanding your minimum acceptable earnout structure, post-close employment term, and personal financial goal before negotiations begin is essential.

Key items: dental-specific M&A advisor or broker engaged before approaching DSOs directly (unrepresented sellers routinely leave 20–40% on the table), dental CPA engaged to recast EBITDA with appropriate add-backs before the LOI stage, attorney experienced in DSO transactions engaged (general business counsel is not sufficient), minimum acceptable earnout structure and post-close employment term determined, rollover equity ask understood (most PE-backed DSOs require 10–30% rollover), clinical autonomy expectations post-close clarified before negotiations begin, and personal financial goal defined (full exit vs. recapitalization vs. partnership growth model).
