The Deal Isnât Done Until Itâs Verified
So youâve listed your practice, found a serious buyer, and agreed on the terms. Youâre almost at the finish lineâbut before you can close, the buyer will need to take a closer look.
This phase is called due diligence, and itâs where theyâll confirm that everything youâve represented about your practice is accurate.
- Think of it as the buyerâs version of a clinical examâchecking under the surface before committing.
In this post, weâll explain what to expect during buyer due diligence, how to prepare, and why a little extra effort now can help avoid delays, renegotiation, or even deal collapse later.
What Is Due Diligence in a Dental Practice Sale?
Due diligence is the buyerâs opportunity to verify:
-
Financial health
-
Patient flow and retention
-
Staffing structure
-
Operational systems
-
Legal and compliance standing
It typically happens after a Letter of Intent (LOI) or Offer Letter is signed but before closing.
Why It Pays to Be Prepared
Buyersâand their advisors (CPAs, attorneys, lenders)âneed to see organized, credible records. If your documents are missing, incomplete, or inconsistent, it can:
-
Create doubt or mistrust
-
Trigger price renegotiations
-
Delay financing approval
-
Lead to deal fatigue or cancellation
Solid preparation helps keep the process smooth, builds buyer confidence, and protects the value of your practice.

Tips for Making the Process Smoother
Create a Digital Data Room
Use a secure cloud folder (e.g., Google Drive, Dropbox) to upload documents and share access. Organize it with clear folders and file names.
Be Transparent and Accurate
If thereâs a down year or production dip, explain it upfront. Buyers respect honestyâand often understand when issues are well-documented.
Donât Share Everything at Once
Only share information after an LOI is signed and a confidentiality agreement is in place. Work with your broker to control the flow and timing.
Work With Professionals
An experienced dental CPA and practice broker can help you prep documents, explain add-backs, and avoid red flags that may raise buyer concerns.
Common Seller Mistakes During Due Diligence
Avoid these missteps that can stall or jeopardize a sale:
-
Inconsistent reporting (e.g., P&L vs. tax return numbers)
-
Incomplete patient data or inflated âactive patientâ counts
-
Unclear staff roles or undocumented pay structures
-
Missing lease agreements or surprise facility issues
-
Being slow to respond to buyer questions or document requests
What Buyers Take Away From This Process
Itâs not just about the numbers. Due diligence helps buyers understand:
-
How the practice really operates
-
Where the strengths and risks lie
-
Whether the seller is organized and transparent
-
How easily they can step in as the new owner
The smoother this process is, the more confident theyâll feel about the investmentâand the more likely theyâll follow through.
Preparation Protects Value
Preparing for due diligence might feel tedious, but itâs one of the most important steps in selling your practice. It protects the price youâve negotiated, speeds up the closing timeline, and helps the buyer trust that theyâre getting exactly what youâve promised.
Remember: a buyerâs confidence is your leverage.
Be prepared, be transparent, and let your practice speak for itself.
