Tracking Your Money & Keeping Records

Understanding Cash Flow

Cash flow is the movement of money into and out of your optometry practice. It is not the same as profit. A practice may show a profit on paper while still having too little cash to pay payroll, rent, lab bills, or equipment loans on time. Think of your bank account as a water tank. Patient payments, insurance deposits, contact lens sales, and eyewear purchases fill the tank. Payroll, rent, utilities, frame orders, lab invoices, taxes, and loan payments drain it. Your job is to know how quickly the tank is filling and how quickly it is draining.

Review cash flow by week, not only by month. Optometry practices often have uneven collections. A busy clinic may complete many exams in one week, but insurance payments may not arrive for several weeks. A large frame or lens order can also require cash before the related patient payment is collected. Tracking the timing of money is just as important as tracking the total amount.

The Importance of Basic Records

Accurate records give you a clear view of the practice's financial health. Record daily collected revenue by source, such as exams, medical eye care, optical sales, contact lenses, copays, and insurance payments. Track every major expense, including payroll, rent, utilities, frame inventory, lens laboratory charges, electronic health record fees, merchant fees, malpractice insurance, and equipment maintenance.

Keep business and personal spending separate. Reconcile the practice bank account and credit card every month. Match deposits to the practice management system and point-of-sale reports. If the reports show $18,000 in optical sales but only $15,500 reached the bank, find out whether the difference is caused by insurance receivables, refunds, merchant batches, or an entry mistake.

Good records also make tax planning easier. Your bookkeeper and tax professional can work from complete information instead of trying to rebuild the year from receipts, bank statements, and memory. More importantly, you can decide whether the practice can afford a new autorefractor, another optician, extended hours, or a second location.

Real-World Scenario

Consider an independent optometry practice with two exam rooms and a small optical. During one month, the practice completes 420 exams and generates $82,000 in billed revenue. However, only $61,000 is collected during that month because several vision plans and medical claims are still outstanding. At the same time, the practice pays $24,000 in payroll, $8,500 in rent and utilities, $11,000 for frames and lenses, and $7,000 for operating costs.

If the owner looks only at billed revenue, the month appears strong. If the owner reviews collected cash, the picture is tighter. The practice needs a plan for unpaid claims, optical vendor terms, and upcoming payroll. A weekly cash review would show this issue early rather than after the bank balance becomes uncomfortable.

The Bootstrapper's Ledger

The Bootstrapper's Ledger is a simple weekly record of money received, money paid, and money still expected. It does not require complicated finance software. Use a spreadsheet with one row for each week. Record collected exams, optical sales, contact lens sales, medical visits, insurance deposits, refunds, payroll, rent, lab costs, frame purchases, supplies, taxes, debt payments, and other expenses.

Calculate three basic figures:

- Cash received: All money that actually reached the bank during the week.
- Cash paid: All payments that left the bank during the week.
- Cash left after bills: Cash received minus cash paid.

Also list expected insurance deposits, patient balances, vendor bills, payroll dates, and tax payments for the next 13 weeks. This makes your cash runway visible. Cash runway is the number of weeks the practice could operate using its current cash if no new money came in. Use available cash divided by average weekly cash paid. If the practice has $90,000 available and spends $15,000 per week, its runway is six weeks.

Forecasting and Decision Making

A cash forecast helps you make safer operating decisions. Before hiring an additional optician, enter the expected wage, payroll taxes, training hours, and likely sales increase. Before buying an OCT, include the deposit, financing payment, service contract, and expected medical eye care revenue. Before ordering a large frame collection, review current inventory, vendor terms, and sell-through rates.

Build a rolling 13-week forecast and update it every Monday. Mark payments as confirmed, likely, or uncertain. Treat unpaid insurance claims as uncertain until they are processed and paid. If the forecast shows less than eight weeks of operating cash, delay nonessential purchases, accelerate claim follow-up, review low-margin services, and arrange financing before the problem becomes urgent.

Conclusion

Managing cash flow is a basic operating skill for every optometry practice owner. Reliable records show what was collected, what was spent, what is still owed, and what is coming due. A short weekly review can prevent missed payroll, rushed borrowing, and poorly timed equipment purchases. You do not need a complicated system. You need consistent records, clear categories, and the discipline to act on what the numbers show.

*Example Scenario: An owner plans to replace an aging visual field analyzer. The 13-week forecast shows that the practice can cover the deposit and monthly payment only if two large insurance batches arrive on time. The owner first confirms those claims, builds a reserve for payroll, and negotiates a payment schedule with the equipment supplier before signing the purchase agreement.*
