Key Takeaways

• Every dental practice has key employees, but no critical process should depend on only one person.
• Understanding who controls financial systems, passwords, payroll, and vendor relationships helps reduce business risk.
• Cross-training and documentation protect the practice while allowing experienced employees to focus on higher-value work.
• Strong internal controls reduce errors, improve continuity, and make staffing transitions much smoother.
• Planning for employee turnover before it happens creates a more resilient and valuable dental practice.

A great office manager can make owning a dental practice significantly easier. They know the patients, the team, the insurance companies, the vendors, the software, and the thousand little details that keep the office functioning.

Over time, that knowledge becomes incredibly valuable, but it can also become a risk. The issue isn’t that you have an employee who knows a lot. You should hope you do. The problem arises when only that employee knows it and the practice owner doesn’t realize how dependent the business has become until the person gives notice.

That’s when seemingly simple questions suddenly become very difficult: Who has the login? When is this report filed? Who do we call at the payroll company? Why is this insurance claim handled differently? Where is that contract? How does this adjustment get entered?

The time to answer those questions is while the employee is still happily working for you.

Start With What You Don’t Know

Most dentists don’t need to know how to perform every administrative task in their practice. That’s why you hire capable people. You do, however, need enough visibility to understand how the business works and where critical knowledge resides.

Consider some basic questions.

• Could you identify everyone who has access to the practice’s bank accounts and credit cards? 
• Do you know who can change payroll information? 
• Where are vendor contracts stored? 
• Who manages insurance credentialing? 
• Who knows how patient refunds are processed? 
• Who has administrative access to your practice management software?

Now take it one level deeper. If the person responsible for one of those functions were suddenly unavailable, who would take over? If your answer is “I’m not sure,” you’ve found a vulnerability.

Financial Processes Deserve Particular Attention

This becomes especially important when one employee controls several pieces of a financial process. Suppose the same employee enters vendor bills, approves payments, reconciles the bank account, handles patient refunds, and has access to online banking. Even if you trust that employee completely, the process itself lacks sufficient checks and balances.

Good internal controls are not an accusation. They’re protection for the practice and the employee. Separating responsibilities, reviewing bank reconciliations, establishing approval thresholds, limiting system access appropriately, and maintaining clear documentation reduce the chances of both errors and fraud. They also make transitions much easier when responsibilities change.

Practice owners should understand these processes well enough to know what controls exist and periodically confirm they’re working. That’s different from doing the work yourself.

Some Knowledge Is Harder to Replace Than It Looks

Financial procedures aren’t the only concern. Dental practices often have highly specialized institutional knowledge that accumulates quietly over many years.

An experienced insurance coordinator may understand the quirks of every major plan. A long-time office manager may know which vendor can get a broken compressor repaired quickly, how to resolve a particular payroll issue, or which step in the scheduling process keeps hygiene production on track.

Much of that knowledge never appears in a formal job description. That’s why replacing an experienced employee can be so disruptive even when you hire a talented successor. The new employee isn’t just learning a job. They’re trying to reconstruct years of accumulated knowledge. Documentation helps, but this shouldn’t become a project where someone writes a 200-page manual nobody ever reads. Focus first on the processes that would create the greatest disruption if knowledge disappeared tomorrow.

When Knowledge Becomes Part of Someone’s Value

In some practices, knowledge stays concentrated because being the person who knows how everything works can become part of someone’s identity and sense of value. The employee who always has the answer, fixes the problem, or knows the workaround may understandably feel more secure because others depend on them.

That can make documentation and cross-training feel threatening, even when no one intends it that way. If sharing knowledge is introduced as “we need to make sure we can function without you,” an employee may hear, “we’re trying to make you replaceable.”

The better message is that strong practices do not reduce the value of experienced employees by sharing knowledge. They increase it. The goal is to free key people from being the only person who can handle routine issues so they can spend more time leading, improving processes, training others, and solving higher-level problems.

Build Redundancy Where It Matters Most

Cross-training doesn’t mean everyone needs to know how to do everyone else’s job. It means critical functions should have backup. 

Payroll is an obvious example. At least one other person should know what happens if the usual payroll contact is unavailable. The same is true for banking access, insurance processes, billing, software administration, vendor management, and other functions that could interrupt operations or cash flow.

You also need to think about access itself. Practice owners sometimes discover after an employee leaves that the former employee’s email address is tied to a critical account, a two-factor authentication code goes to their personal phone, or no one else has administrator privileges.

Those are preventable problems. Periodically review who has access to critical systems, what level of access they have, and what happens when someone changes roles or leaves the practice. This should be part of your normal business procedures, not something you figure out during an employee’s final week.

Don’t Wait for a Resignation to Conduct the Exercise

Pick one key employee in your practice and imagine that person gave two weeks’ notice today. Then ask: What would we need that person to teach us before leaving?

Write down everything that comes to mind. Now look at the list and identify the things you shouldn’t have to scramble to learn during someone’s notice period. Those are the areas to address first.

You may discover that the solution is documentation. In other cases, it may be cross-training, better system access, improved internal controls, clearer job responsibilities, or simply greater owner awareness.

And don’t make this exercise about one employee. Once you’ve worked through the office manager’s responsibilities, repeat it for other key positions. The objective isn’t to make employees interchangeable, since great employees aren’t. Their judgment, experience, relationships, and institutional knowledge have enormous value.

The objective is to make sure the business itself remains stable when people change. Turnover happens. People retire. Families relocate. Employees take parental leave, care for aging parents, become ill, or pursue new opportunities. Even the most loyal employee will eventually leave the practice. A well-run practice plans for that reality without diminishing the importance of the people who work there.

At Edwards & Associates, we spend a lot of time helping dentists understand what’s happening financially inside their practices. But good financial management also requires understanding the processes behind the numbers: who handles the money, what controls are in place, where information lives, and whether the practice could continue operating if a key person suddenly wasn’t available. You don’t need to know everything your office manager knows. You do need to know enough about your business to make sure no single employee is the only person who does.
