Pre-Acquisition Financial Due Diligence for Dental Buyers

The practice looks profitable on paper. But how much of that revenue is real, and how much is sitting in unreconciled limbo?

📚 Part of our DSO series: This article is part of The DSO Financial Operations Playbook, our comprehensive guide to building scalable financial operations across multiple dental practice locations.

Why Financial Due Diligence Makes or Breaks Acquisitions

Acquiring a dental practice is a significant investment. Whether you are a DSO adding to your portfolio, a private equity firm entering the dental space, or a dentist buying your first practice, the financials need to tell a true story.

Surface-level numbers can be misleading. A practice reporting $1.5 million in collections might have $75,000 in unreconciled deposits sitting in suspense accounts. Another practice showing strong margins might be writing off legitimate revenue as bad debt because nobody followed up on denied claims. Without thorough due diligence, buyers inherit problems they did not anticipate and pay premiums for revenue that does not actually exist.

The practices that look cleanest on the surface sometimes hide the messiest problems underneath. Sellers preparing for a transaction often dress up their numbers, accelerating write-offs to clean up aged receivables or delaying recognition of problems until after closing. Sophisticated buyers know to look beyond the summary reports and dig into the operational details that reveal how money actually flows through the practice.

Revenue Verification Starts at the Bank

The fundamental question in any dental acquisition is simple: Does the money in the bank match the revenue reported in the practice management system? This sounds obvious, but the answer is surprisingly often no.

Request twenty-four months of bank statements alongside corresponding PMS payment reports for the same period. If the practice claims to have collected $1.2 million last year, the bank deposits should reflect that amount. When they do not match, you need to understand why.

Some variance is normal. Timing differences between when payments are received and when deposits post can create temporary gaps. Credit card settlements may show different dates than PMS entries. These legitimate timing differences should be documented and should resolve within a few days.

What you are looking for are persistent gaps that never resolve. Unidentified deposits that sit on the books for months without explanation. Consistent discrepancies between what the PMS says collected and what actually reached the bank. When you ask about these gaps and the answers rely on memory rather than documentation, you have found a red flag.

Insurance payments deserve particular scrutiny because they represent forty to sixty percent of revenue for most practices. EFT deposits should match ERA documentation. Posted payments should correspond to actual deposits. When you pull a sample of twenty or thirty EOBs and try to trace them to ledger entries, the trail should be clear. Practices that cannot match deposits to specific remittances have a reconciliation problem that will become your problem after closing.

Accounts Receivable Quality Matters More Than Quantity

A practice showing $200,000 in accounts receivable might look like it has strong revenue still coming. But if half that receivable is over ninety days old, you are looking at a collection problem, not future revenue.

The age distribution of receivables tells you how well the practice converts production into actual collected revenue. Industry benchmarks suggest that no more than fifteen percent of AR should be over ninety days. Practices significantly above that threshold either have collection process failures or are carrying balances that should have been written off long ago.

Look at the trend over time rather than just a snapshot. Is AR growing faster than revenue? That suggests the practice is producing but not collecting, which means the revenue numbers overstate actual economic performance. Is there a sudden drop in AR right before the sale? That might indicate a cleanup effort to make the books look better for buyers.

Credit balances also reveal operational health. When patients have credits on their accounts, it usually means either overpayments that need refunding or posting errors that created false credits. A practice with credit balances exceeding two percent of monthly collections has posting accuracy problems. Old credits that sit unresolved for months suggest nobody is reviewing accounts carefully.

Production and Collection Rate Verification

Sellers love to cite collection rates, but those rates are only meaningful if you understand how they are calculated and can verify the underlying numbers.

The gross collection rate divides actual collections by gross production. The net collection rate divides collections by production after contractual adjustments. Both numbers matter, but they tell different stories. A practice collecting ninety-five percent of adjusted production is performing well. A practice collecting seventy percent of gross production might also be performing well if their adjustment rate reflects realistic insurance contracts.

What you want to avoid is accepting stated collection rates without verification. Pull the underlying reports. Calculate the rates yourself. Compare the calculation methodology across time periods to ensure consistency. Practices that show volatile collection rates from month to month either have seasonal patterns that should be explainable or have data quality issues that make the numbers unreliable.

Production accuracy matters because production drives valuation. Verify that stated production can be traced to actual patient records. Check that fee schedules align with market rates. Look for unusual spikes in procedure volume in the months before the sale, which might indicate accelerated treatment or, worse, phantom production designed to inflate the numbers.

Internal Controls Signal Management Quality

The financial controls a practice maintains reveal how seriously they take financial management. Practices with weak controls have more errors, more fraud risk, and more surprises waiting for buyers.

Segregation of duties is fundamental. The person who posts payments should not be the same person who makes deposits, who should not be the same person who reconciles accounts. When one person handles the entire financial process from collection to reconciliation, there is no independent verification that everything is being done correctly. This is not about assuming dishonesty. It is about creating systems where errors get caught and honest people are not placed in positions of unverified trust.

Adjustment controls matter because adjustments are where money disappears. Every adjustment reduces what the practice collects. Legitimate adjustments have documented reasons, appropriate approvals, and logical patterns. Practices with round-number adjustments, high adjustment volumes, or adjustments made without approval have control weaknesses that affect their true financial performance.

Interview the staff who handle the money. Ask them to walk you through the daily deposit process, the insurance payment reconciliation, what happens when deposits do not match. Their answers should be clear, consistent, and align with what the documentation shows. When descriptions are vague, when processes depend on one person's memory, when there are contradictions between what people say and what records show, you have found operational weaknesses that will require post-acquisition attention.

Technology and Systems Evaluation

The practice management system contains the data you need to verify everything else. If the PMS is unreliable, all the reports generated from it are unreliable.

Modern, supported software is not just about features. It is about data integrity. Outdated or unsupported systems may have bugs, security vulnerabilities, or limitations that affect the accuracy of financial records. Find out what platform the practice uses, what version they run, and whether they have maintained proper backups.

Audit trails matter for investigation and accountability. Systems that track who made changes, when, and what they changed allow you to trace problems to their sources. Systems with disabled audit trails or no change tracking leave you unable to verify what happened or who was responsible.

User access controls reveal how seriously the practice takes data security. When everyone has administrator access, there is no accountability. When the person who left two years ago still has active credentials, there are security gaps. These details matter both for what they say about past management and for the work required to establish proper controls after acquisition.

The Cost of Skipping Due Diligence

Buyers who shortcut financial due diligence face predictable consequences. Valuation surprises emerge when revenue that looked solid turns out to include significant unreconciled or uncollectible amounts. Integration becomes harder when messy books make it impossible to establish clean baselines for post-acquisition performance measurement.

Staff problems often accompany financial control issues because the same management weaknesses that allow financial sloppiness also affect other operational areas. Ongoing losses continue after closing because the problems that existed before acquisition do not magically resolve with new ownership.

Thorough due diligence takes time and costs money. Engaging professionals to verify financial claims, analyze records, and identify red flags requires investment. But discovering a $50,000 reconciliation problem before closing is far better than discovering it after, when it becomes your problem to solve with your money.

The practices that can demonstrate clean books, clear processes, and verified revenue command premium valuations because they present lower risk. The practices that cannot demonstrate these things should be priced accordingly, or perhaps reconsidered entirely.
