💡 Core Concepts & Executive Briefing
Understanding Cash Flow
Cash flow is the movement of money into and out of your optometry practice. In this business, money comes from exam fees, eyewear sales, contact lens sales, medical services, and sometimes vision plan reimbursements. Money goes out for staff pay, rent, lab bills, frame inventory, lens orders, software, equipment leases, and taxes. If more money goes out than comes in, the practice gets tight fast.
Think of your practice like a contact lens case. If it is not filled on time, it dries out. Cash works the same way. A practice can look busy all day long and still run short on cash if patient payments are delayed, insurance claims are slow, or inventory is tied up in frames that do not sell.
The Importance of Basic Records
Good records are the foundation of a healthy optometry practice. You need to know what came in, what went out, and what is still owed to you. That means tracking collections from patients, vision plans, medical insurers, lab invoices, payroll, sales tax, frame purchases, and equipment payments. Without clean records, you cannot tell if the practice is actually profitable or just busy.
Records also help you spot waste. Maybe your optical is over-ordering frames that sit for months. Maybe lens remakes are climbing because prescriptions are being entered wrong. Maybe a front desk team member is collecting less copay than they should. Strong records show the truth.
Real-World Scenario
Picture a two-doctor optometry practice with a busy optical. The schedule is full, and the team feels good. But the owner notices bank balances are still thin. When they review records, they find that vision plan receivables are aging past 45 days, frame inventory is too high, and contact lens rebates are not being tracked. The practice is selling, but cash is leaking out in three places.
That is common in optometry. Revenue does not always hit the bank on the same day the patient walks out. Some money is tied up in claims, some is tied up in inventory, and some is tied up in accounts receivable. You need a system that shows the full picture.
The Bootstrapper's Ledger
You do not need fancy software to start. A simple weekly ledger can work if it is used every week. Track:
- Exam revenue
- Optical sales
- Contact lens sales
- Medical insurance collections
- Outstanding insurance claims
- Payroll
- Rent and utilities
- Lab costs
- Frame and lens inventory purchases
- Taxes owed
This gives you a clear view of burn rate, which is how fast you are spending cash, and cash runway, which is how long you can keep operating if collections slow down.
For example, if your practice has $60,000 in cash and your average monthly outflow is $20,000 more than inflow during a slow season, your runway is only three months. That tells you to tighten collections, slow inventory purchases, and delay non-essential spending.
Forecasting and Decision Making
Cash flow forecasting helps you make smart calls before problems hit. If you know summer is slower because families are traveling and elective eyewear sales dip, you can prepare. If you know a new OCT lease payment starts next month, you can plan for it. If a big frame buy is coming before trunk show season, you can decide whether the practice can support it.
Forecasting also helps with hiring. You may want to add an optician, scribe, or billing help, but only if your collections can support the new payroll. It also helps with marketing. A back-to-school campaign for pediatric exams or a dry eye promotion can be timed when cash allows.
Conclusion
Managing cash flow and keeping clean records is not just bookkeeping. It is practice control. In optometry, the owners who win are the ones who know their numbers before the month ends, not after the tax bill arrives. When you track collections, receivables, payroll, and inventory closely, you protect the practice and give yourself room to grow.
