Most dentists decide to sell about a year before they want to be done, call a broker, and discover that the practice is worth less than they assumed and that several fixable things cannot be fixed in twelve months. The financials are messy with personal expenses. Collections dipped last year because the owner cut back to four days. The equipment is 22 years old but a new CBCT was bought last spring. The best hygienist is 63 and planning to retire with the owner.
None of those is a disaster, but all of them cost money at closing. A five-year runway turns each into a manageable project.
This post lays out the work year by year, gets specific about the financial cleanup that drives price, addresses the equipment reinvestment question sellers get wrong in both directions, and compares the three real exit paths. Verify tax and legal specifics with your own CPA and dental-specific attorney.
Key takeaways
- Buyers and lenders look at three years of tax returns and practice management reports. That means the cleanup has to start at least three years before closing, and five gives you room to fix a bad year.
- Do not coast at the end. The single most expensive transition mistake is reducing days, deferring hygiene recall, and letting collections drift in the final two years, because that decline is what gets valued.
- Add-backs are legitimate and expected, but every add-back you claim is a line a buyer's accountant will test. Fewer, cleaner, better-documented add-backs produce a higher net price than a long list of arguable ones.
- Near a sale, replace equipment that fails diligence or blocks operations and skip the discretionary upgrades. Most capital purchases in the last two years do not return their cost in price.
- Decide your path (associate sale, DSO or group sale, or wind-down) by year three, because each one requires different preparation and they are not interchangeable at the end.
- Staff continuity is part of the asset. A buyer paying for goodwill is paying partly for the people the patients know.
Why five years and not two
Three constraints set the timeline.
Lenders look back three years. An SBA lender financing a buyer will typically want three years of business tax returns plus interim statements. A weak year inside that window depresses what the buyer can borrow, which caps what they can pay, no matter how strong the trailing twelve months look.
Trend matters more than level. Two practices collecting $1.2 million are valued differently if one has grown 4% a year for three years and the other has declined 5% a year. A five-year runway lets you produce a rising three-year trend at the point of sale. A two-year runway does not.
Some fixes take years. Hiring and integrating an associate who might buy in. Rebuilding a hygiene recall system to lift the active patient count. Converting from a heavy PPO mix. Renegotiating a lease so the term supports a buyer's loan. None of those are twelve-month projects.
The end-of-career coast is the most expensive habit in dentistry. It is completely understandable: you are tired, you have enough, and the four-day week is nice. But a practice that goes from $1.3 million to $1.0 million over three years while the owner works less does not get valued at $1.3 million with an explanation. It gets valued at $1.0 million, with the decline used as leverage. If you want to work less, do it by delegating and adding hygiene capacity rather than by closing days.
The five-year plan, year by year
| Year | Focus | Concrete work |
|---|---|---|
| Year 5 (five years out) | Baseline and direction | Get an informal valuation or opinion of value; assemble your advisory team; pull three years of reports; identify your likely exit path; fix any glaring compliance gap |
| Year 4 | Financial hygiene and revenue | Begin removing personal expenses from the practice entity; put family payroll on a defensible basis or off; build the hygiene recall system; address payer mix |
| Year 3 | Path decision and infrastructure | Commit to a path; if it is an associate sale, hire or identify the associate now; renegotiate or extend the lease; complete deferred equipment replacements; clean up A/R |
| Year 2 | Clean numbers on the record | This is a year a buyer will read closely; run it clean; minimal capital spend; document systems and staff roles; consider a quality-of-earnings review if a DSO sale is likely |
| Year 1 | Marketing the practice and closing | Engage broker or attorney; assemble the diligence package; field offers; negotiate; close; plan the transition period and the announcement |
Cleaning up the financials
This is where the money is. Everything else on the list is secondary.
What buyers actually reconstruct
A buyer or appraiser rebuilds your practice as if it were operated normally by someone else, then measures what it earns. That means:
- Personal expenses run through the practice get added back to earnings, which helps you, but only the ones you can prove.
- Below-market or above-market items get restated to market. If your spouse is on payroll at $90,000 for 6 hours a week of bookkeeping, the excess is an add-back. If you own the building and charge the practice $2,000 a month for space that would rent for $6,000, your earnings are overstated and will be adjusted down.
- One-time items are removed in both directions: the hail damage repair, the legal fee from the employment dispute, the pandemic-era relief.
The add-back problem
Add-backs are normal and legitimate. The problem is that every one of them is a negotiation, and a long list signals messy books, which makes a buyer discount everything else too.
| Add-back type | How buyers treat it | What to do by year 3 |
|---|---|---|
| Owner auto, travel, meals beyond business purpose | Usually accepted with documentation | Keep them but document clearly, or move them out to simplify |
| Family member payroll above market for actual work | Accepted for the excess, if the role and hours are documented | Right-size or remove; keep a written job description |
| Owner retirement plan contributions | Usually accepted as discretionary | Keep; easy to document |
| Personal insurance premiums (life, disability, some health) | Usually accepted | Keep; easy to document |
| Continuing education that is really a vacation | Partially accepted, often argued | Reduce or accept the haircut |
| Cash collections not deposited | Not accepted, and a serious problem | Stop immediately. Unreported revenue cannot be sold, and claiming it in a negotiation is an admission |
| Below-market rent to an owner-controlled entity | Adjusted down to market, reducing value | Move rent to market at least three years out so the trend is clean |
The rent trap. If you own your building and have been charging the practice artificially low rent to boost practice profit, or artificially high rent to move income to the real estate entity, fix it early. Buyers and lenders normalize rent to market. Worse, if you intend to keep the building and lease it to the buyer, an above-market rate will be negotiated down or will cap the price the buyer can pay. Set rent at a defensible market rate three or more years before sale and get a broker's opinion in writing. See lease vs buy and lease terms that matter.
Metrics a buyer will pull, and where you want them
| Metric | Why it matters to a buyer | Typical target |
|---|---|---|
| Collections trend, 3 years | Direction of the business | Flat to rising; declining is a discount |
| Collection ratio (collections divided by net production) | Whether the reported production is real money | Commonly cited in the high 90s percent |
| Active patient count and trend | The actual asset being purchased | Defined consistently (usually seen in 18 months) and stable or growing |
| New patients per month | Whether the practice replaces attrition | Stable; sudden drops get investigated |
| Hygiene reappointment rate | Recurring revenue quality | High; a weak number signals the patient base is leaking |
| Percentage of production done by the owner | Transition risk | The lower, the easier the handoff |
| A/R over 90 days | Billing discipline | Small; large aged A/R is usually excluded from the sale anyway |
| Overhead by category | Whether the buyer can improve it | Within normal ranges; see overhead benchmarks |
| Referrals out | Untapped production the buyer can capture | A selling point if you refer a lot and the buyer does not |
Our post on the KPIs worth tracking covers how to instrument this, and building a recall system addresses the hygiene numbers directly.
Equipment reinvestment near a sale
Every seller asks some version of this: should I buy the CBCT, replace the chairs, upgrade the sensors? The honest answer is usually no, with important exceptions.
The general rule
Capital spending in the last two years before a sale rarely returns its cost in the sale price. A buyer does not pay you a dollar of goodwill for a dollar of new equipment. Equipment enters the valuation mostly as part of the tangible asset allocation and as an absence of a problem, not as a value driver. A $90,000 CBCT bought eight months before closing does not raise the price by $90,000, and it may not raise it at all if the buyer would not have chosen that unit.
The exceptions worth spending on
| Spend on it | Why |
|---|---|
| Anything that will fail a buyer's equipment inspection or a regulatory inspection | It becomes a price deduction plus a credibility problem. Fix it before it is found |
| Sterilizers, compressor, vacuum at or past end of life | These stop the practice when they fail, are visible in diligence, and are relatively cheap to replace |
| Digital radiography if you are still on film | This is a genuine buyer objection and a workflow gap, not a preference |
| Practice management software that is unsupported or ancient | Data migration risk scares buyers and lenders; see practice software basics |
| Amalgam separator, x-ray registration, waterline compliance | Compliance gaps are a deduction and sometimes a deal delay. See x-ray registration and amalgam separators |
| Cosmetic refresh: paint, flooring, reception furniture, signage | Cheap, and first impressions affect buyer enthusiasm disproportionately |
The ones to skip
- A CBCT, milling unit, or laser you have not been using and will not use in the time remaining. If you would not buy it with a 10-year horizon, do not buy it with a 2-year one.
- Full operatory replacements when the existing chairs are functional. Buyers discount tired but working chairs less than the cost to replace them, and a buyer may prefer to choose their own. See what used dental chairs sell for.
- Financed equipment that will still have a balance at closing. Equipment debt has to be paid off or assumed, and it complicates the deal. If you must buy, pay cash or plan to retire the note.
The three-year test. For any capital purchase within five years of your intended exit, ask: will this pay for itself through production or savings before I sell? If yes, buy it. If no, but it prevents a diligence problem, buy it. Otherwise, do not. And check the tax treatment either way, since Section 179 and bonus depreciation change the after-tax cost and can also create depreciation recapture consequences at sale that your CPA should model.
Staff planning
A buyer paying for goodwill is buying a patient base that has relationships with your team, not only with you. Staff turnover at transition is the most common cause of post-sale revenue decline, and buyers know it.
Staff work in the five-year window
- Map who is likely to retire or leave within two years of your exit, and start cross-training replacements now
- Document roles, systems, and passwords so the practice does not run out of anyone's head
- Move informal arrangements (unwritten PTO, cash bonuses, flexible hours) onto paper so the buyer knows what they are inheriting
- Review wages against market so the buyer does not face an immediate payroll increase, which reduces the earnings they are buying
- Confirm employment classification is correct, especially for hygienists and any contractor arrangements
- Consider stay bonuses payable at and after closing for key team members, funded from proceeds and negotiated into the deal
- Decide your communication plan and timing; do not tell the team informally and then go quiet for six months
Do not announce too early or too late. Telling the team three years out invites attrition during exactly the period you need stable numbers. Telling them the week before closing burns trust and can trigger resignations at the worst moment. Most transitions are announced once the deal is firm and close is scheduled, with the buyer present and a clear message about continuity. Coordinate with the buyer and your attorney, and remember that employment law obligations around notice vary by state. See managing a dental team.
The three exit paths
Decide by year three, because the preparation diverges.
Path 1: Sale to an associate or partner
The most common ideal and the most commonly bungled. It works when you hire the associate early enough for them to build patient relationships, produce enough to justify the price, and qualify for financing.
| Advantages | Risks |
|---|---|
| Best continuity for patients and staff | Associate may not be able to obtain financing |
| Buyer already knows the practice, shortening diligence | Associate may lose interest or leave, taking patients and your timeline with them |
| You can structure a gradual handoff | Personal relationship makes negotiation awkward; people avoid hard conversations |
| Often no broker fee | Price expectations can be unrealistic in both directions |
How to de-risk it: put the intention in writing early, with a valuation method agreed in advance and a date by which the associate must commit and obtain a financing pre-approval. Keep a second path alive until the associate's loan is approved. Never stop marketing to the world on the strength of a handshake. The mechanics of a staged buy-in are covered in from associate to partner.
Path 2: Sale to a DSO or group
Realistic mainly for larger practices with associates already in place, where adjusted EBITDA after paying a market-rate dentist is substantial. Requires that you stay and work, usually two to five years, and part of the consideration is often rollover equity and earnout rather than cash.
Preparation differs: clean, accrual-quality financials matter more, a quality-of-earnings review is common, and the employment agreement is as important as the purchase price. Read DSO consolidation for how the buyers think and how practices are valued for why the two valuation bases give different answers.
Path 3: Wind down and walk away
Under-discussed and sometimes correct. If the practice is small, heavily owner-dependent, in a hard-to-staff location, or has a patient base built entirely on your personal relationships, the sale price after broker fees and taxes may be modest relative to the effort and the multi-year commitment a structured sale requires.
Hypothetical example. Illustrative only.
A solo dentist in a small town collects $520,000 with $210,000 of pre-doctor cash flow. Two years of marketing produce no qualified buyer willing to relocate. A broker suggests the realistic price is around $300,000 with seller financing.
The alternative: work three more years at roughly $200,000 of owner income (about $600,000 total, taxed as ordinary income either way), then sell the patient records to a practice one town over for a modest amount, sell the equipment on the used market, and close. The proceeds are smaller, but the dentist controls the timing completely and owes no post-close employment obligation.
Whether that is better depends on the tax treatment of a sale (capital gain on goodwill versus ordinary income on wages), the real estate, and how much the extra three years of work is worth to them personally. Model both with a CPA. The point is that "no buyer" is not the same as "no plan."
If you go this route, handle records retention, patient notification, and equipment disposition properly. State law generally governs how patients must be notified and how records are transferred or retained. See dental records retention and what to do with equipment first, and confirm your state's specific requirements with your board.
The diligence package, assembled early
What a buyer will ask for
- Three years of business tax returns plus year-to-date financials
- Three years of production, collection, and adjustment reports by provider
- Active patient count with the definition used, and new patient counts by month
- Procedure mix report and fee schedule
- Payer mix with percentage of collections by plan, and current contracted fee schedules
- A/R aging
- Staff roster with hire dates, roles, wages, hours, and benefits
- Equipment list with ages, service history, and any equipment leases or notes
- Lease and any amendments, or property information if you own
- Compliance documentation: OSHA, HIPAA risk analysis, sterilization logs, x-ray registrations, waterline testing
- Any pending claims, board complaints, or employment disputes
- Software version, hosting arrangement, and backup evidence
Assembling this in year two rather than during negotiation does two things: it surfaces problems while you can still fix them, and it signals to a buyer that the practice is well run, which is worth real money in a negotiation. The due diligence checklist covers the buyer's side of the same list.
Getting started this month
If your exit is five years out, three things are worth doing in the next 30 days. Ask your financial planner how much you actually need from the practice, which sets the whole plan. Pull three years of collections, active patient count, and new patients per month and look at the trend line honestly. And walk your office once as if you were a buyer seeing it for the first time, writing down every deferred repair, every piece of dead equipment, and every system that exists only in your head.
Then pick one thing from year 4 of the table above and start it. Financial cleanup is usually the highest-return item, because it affects the number a lender will lend and therefore the price a buyer can pay.
