Dr. Hayes is not one client. She is a few of them, and the pattern is common enough to walk through in detail. Numbers in this piece are illustrative. No real client data appears.

After eight years in practice, her optical margin was running 47 percent, which is about eight points below the range Cleinman Performance Partners calls well-run for an optical dispensary. She had no idea. All optical and clinical revenue was combined in a single account, so the optical margin had never existed as its own number. By month six of having the chart of accounts rebuilt to split those two lines, she knew what the number was. By month twelve, it had moved.

What the books looked like when we started

One revenue line. Clinical income and optical income, combined into a single "Practice Income" account. Frame costs somewhere in supplies. Payroll as one figure with no function breakdown. A month-end close that came out, when it came out at all, somewhere in the third week of the following month.

The practice was profitable. The tax return confirmed it. What the tax return could not confirm was whether optical was profitable on its own, whether payroll had been slowly rising relative to collections, or where the frame board actually stood on margin. She was making those decisions by feel, which is more common than the accounting industry tends to admit.

The first 90 days

Rebuilding the chart of accounts took about six weeks. Two revenue lines: clinical services and optical dispensary. Two cost-of-goods lines to match, one for clinical supplies and one for frames and lenses. Payroll broken out by function. A handful of miscoded transactions corrected going back about eighteen months. The work is not technically complicated; it is slow because each categorization decision determines what the monthly report will tell you later.

The first close came out fourteen days after month-end. The second was out on day nine. By month three, day seven.

What the numbers said

Optical gross margin: 47 percent. The gap from the 55-to-65-percent range Cleinman benchmarks was not one thing. Frame turns were slow in two product lines. Lab costs had drifted up without a contract review in three years. Pricing on a mid-range frame category had not moved since 2021.

None of it was a crisis. It had also never been visible.

The clinical margin was in better shape. That mattered because it changed what the path forward looked like. If both sides had been underperforming, the options would have been different, and more expensive.

What changed, and what did not

The decisions that eventually moved the margin were hers: tightening the frame assortment in two product lines, raising prices in a third, setting a quarterly calendar prompt for the lab contract review. Those are not accounting decisions. Accounting produced the number she had been making those decisions without.

Over the following year, optical gross margin moved from 47 to 53 percent. Still below the top of the Cleinman range. Whether the accounting caused that shift or ran alongside decisions she would have made anyway is genuinely hard to say. The decisions happened, and they happened faster than they would have without a monthly number to look at.

One thing that did not change: her billing manager still runs the receivables. Claim submission, ERA posting to patient accounts, following up on denials, patient balances. That work stays inside the practice because it belongs inside the practice, owned by whoever runs the billing function. The accounting work starts once the cash reaches the bank: recording the batch deposits, tying them to the collections report the billing manager produces, then the monthly financial. This line is worth drawing clearly because practices sometimes assume their outside accountant handles more of the billing cycle than any outside firm does or should.

The two numbers she actually looks at each month

Optical gross margin and payroll as a percentage of collections.

The second one took some explaining when we first introduced it. Payroll as a dollar figure does not tell you enough on its own. In a month where collections are $90,000, $18,000 in payroll is 20 percent. In a month where collections are $120,000, the same $18,000 is 15 percent. The ratio is what matters, and it moves before the dollar amount gives you any useful signal. A practice can add one staff member and not notice the payroll-to-collections drift for six months if it only tracks the dollar.

She reads these two numbers in the first week of each month. The full report she goes through quarterly.

Who this is for, and who it probably is not

Practices above about $500,000 in annual collections that cannot currently separate their optical and clinical margins are making decisions with a gap in the picture. Not always a damaging gap. But a gap worth closing.

Below $500,000, the math changes. An ongoing monthly accounting relationship takes on a different proportion of revenue at that scale, and the investment may not pay off until the practice grows. A lighter bookkeeping arrangement alongside annual tax prep is often more appropriate at that stage.

If the owner is not going to read monthly numbers, the investment does not pay off regardless of practice size. The monthly report is a tool. It works when someone uses it to make a decision; otherwise it is a file you archive every month for the tax return.

Questions owners ask about this

How long does it take to get accurate monthly numbers after we start?

For most practices with reasonably clean prior-year books, plan on 60 to 90 days. The first month typically surfaces what is wrong with the chart of accounts. The second month is about fixing it. By month three, the numbers are usually reliable enough to act on. Practices with significant prior-year cleanup can take longer.

Does separating optical and clinical revenue require different software?

No. Most practices do this inside QuickBooks Online with a properly structured chart of accounts. Two revenue lines and two cost-of-goods lines, set up correctly, is usually all it takes. The issue is rarely the software.

What is a typical optical gross margin for an optometry practice?

Cleinman Performance Partners puts the typical range for a well-run optical dispensary at 55 to 65 percent. Below 55 is worth investigating. Above 65 is possible with tight frame management but less common. If you have never tracked this number, finding it in the 47 to 52 percent range at the outset is not unusual.

Our books are a mess. How long would cleanup take before we get useful numbers?

It depends on how far back the issues go and whether prior-year tax returns are filed and accurate. If the last full year is filed and bank reconciliations are complete, getting to reliable monthly numbers typically takes 60 to 90 days. Extensive prior-year cleanup can add another 60 to 90 days. The first step is usually a conversation about what the books actually look like.

We already have a bookkeeper. Is that the same as monthly accounting?

A bookkeeper records transactions. Monthly accounting means someone reviews the numbers each month, flags margin changes or payroll trends, and produces a report the owner can read and use. Some practices have one person doing both functions well. The question is whether you get a monthly report you read and that informs decisions.
