- Profit is not cash, and the gap is where owners get blindsided. A growing practice can post a strong month and still be short on payroll day, because receivables, inventory, and equipment soak up cash the profit line never shows.
- Working capital is six levers, not luck. Inventory turns, how fast clients pay, when you pay suppliers, payroll cadence, the reserve, and a line of credit. Each one is a dial you can actually turn.
- Hold an operating reserve of roughly one to three months of expenses. Advisors cite a range of one to six months; the faster cash runs through your hands, the closer to the top of that range you want to sit.
- A simple 13-week forecast is the cheapest early-warning system there is. Two hours on a Monday shows you a tight week before it lands, while you can still do something about it.
- Above $3 million in revenue, cash discipline is a team sport. OwnerExchange is the one community built exclusively for owners of 3+ DVM practices doing $3 to $10M and up, where the room already knows what a healthy reserve and a clean forecast look like.
The most stressed-out owner I ever sat with was, on paper, doing great.
Her practice was profitable. Three doctors, growing, the kind of year-over-year numbers most owners would envy. And the week we talked, she was lying awake wondering how she was going to make payroll on Friday. Both things were true at the same time, and that contradiction is the single most misunderstood thing in practice finance.
She hadn’t done anything wrong. She’d grown fast, her best clients paid on their own schedule, and she’d just stocked up on inventory. Every one of those is a good-news problem. Together, they’d quietly drained her bank account while her profit-and-loss statement smiled back at her.
One caveat before we go further. I’m a practice owner and a co-founder, not your accountant, and none of this is financial advice. This is about running the cash side of a practice well, the reserves, the timing, the forecast, not about what your practice is worth or when to sell. Talk to a qualified professional about your own numbers.
Why a profitable veterinary practice can still run short on cash
Start with the distinction that fixes most of the confusion. Profit is what you earned on paper. Cash is what’s actually in the account. They are not the same number, and in a growing practice they can point in opposite directions.
Here’s why. Under accrual accounting, the standard method once a practice gets past roughly seven figures, revenue is recorded when it’s earned, not when the money lands. So you can book the revenue, post the profit, and still be waiting on the cash.
Three everyday things open the gap, and none of them shows up on your profit line.
Receivables. Every dollar a client or insurer hasn’t paid yet is profit you’ve earned but can’t spend. Let those pile up and you’re essentially lending money to your clients while your own bills come due.
Inventory. Drugs and supplies cost cash the day they arrive and don’t turn back into cash until they’re used and billed. Overstock, and you’ve parked money on a shelf instead of in the bank.
Growth itself. This is the cruel one. The faster you grow, the more working capital the growth eats. More volume means more receivables and more inventory ahead of the cash that pays for them, so a practice can look wildly successful and feel broke in the same quarter.
That’s the whole puzzle. You can post a record month and struggle to make payroll, because plenty of cash movements never touch the income statement at all.
How to actually read your cash flow
If the profit-and-loss statement is the story of what you earned, the cash flow statement is the story of where the money went. Most owners never read the second one, and it’s the one that tells you whether you can sleep.
It sorts every dollar of movement into three buckets, and the labels are worth knowing.
Operating. Cash from running the practice day to day, after adjusting profit for the receivables and inventory swings above. This is the number that matters most, because it shows whether the core business actually throws off cash.
Investing. Cash spent on or returned from longer-term assets, like a new dental suite, imaging equipment, or a build-out.
Financing. Cash from loans and lines of credit, owner draws, and debt payments.
Here’s the practical move. Glance at operating cash flow next to your net income for the same period. When profit is healthy but operating cash is thin, that’s your signal that money is trapped in receivables or inventory, and it tells you exactly which lever to pull next.
The working-capital levers you can actually pull
Working capital sounds like a finance-textbook abstraction until you see it as a set of dials. It’s just your current assets minus your current liabilities, the short-term money you have to run the place. Cash, receivables, and inventory on one side; what you owe suppliers and on short-term debt on the other.
The good news is that every piece of it is something you control. Here are the six levers, what to actually do with each, and where the cash shows up.
| Cash-flow lever | What to do | Impact on cash |
|---|---|---|
| Inventory turns | Order to about 10% of the week’s revenue; cut dead and slow-moving stock; tighten reorder points | Frees cash off the shelf. AAHA Pulsepoints put drugs and supplies near 10–12% of revenue; total COGS near 20–22% |
| Client payment timing (AR) | Collect at time of service; take cards and payment plans; follow up on aging balances weekly | Pulls earned revenue into the bank instead of leaving it with clients |
| Payables timing (AP) | Use full supplier terms (net 30/60) without going late; capture early-pay discounts only when worth it | Keeps your cash longer without harming vendor relationships |
| Payroll cadence | Know which paydays land before big receivables clear; align the calendar; staff to the schedule | Smooths the single biggest, least flexible cash outflow |
| Operating reserve | Hold roughly 1–3 months of expenses liquid; park it in a money-market or savings account | Turns a bad week into a non-event instead of a crisis |
| Line of credit | Keep one open and unused for short-term gaps; draw, repay, redraw | Bridges timing gaps so growth doesn’t strand you |
Read down that table and the theme lands. None of this is exotic finance. It’s six knowable dials, and turning two or three of them even slightly is usually the difference between a tense month and a calm one.
Two of these deserve a closer look, because they move the most money.
Inventory is cash on a shelf. A common discipline is to cap weekly ordering at roughly 10 percent of that week’s revenue, then hunt down the expired, slow, and duplicate stock that quietly ties up thousands. Every turn you add is cash back in the account.
Receivables are cash in someone else’s bank. The cleanest fix is collecting at the time of service so the balance never ages. For what does age, a weekly five-minute pass on the aging report beats a quarterly panic every time.
Building an operating cash reserve
If you do one thing after reading this, build a reserve. It’s the buffer that turns the scenario I opened with, the profitable owner sweating payroll, into a problem you never have.
How much? The honest answer is a range. The advisors I trust land between one and six months of operating expenses kept liquid, covering everything from payroll and rent to insurance and loan payments. For most multi-doctor practices, one to three months is a sensible working target, with the faster-moving practices sitting higher.
The rule of thumb worth remembering: the faster money runs through your hands, the bigger the reserve you need. A high-volume practice with thin timing margins wants more cushion than a steady one.
There’s a simple way to fund it without feeling the pinch, borrowed from how disciplined owners handle their own finances. Pay the reserve first. Automate a transfer into a separate account every time revenue comes in, the way you’d treat a savings goal, because money tends to expand to fill whatever’s left in the operating account. Build it during your strong months so it’s there for the slow ones.
And don’t let it sit dead. Many banks pay 4 to 5 percent on savings and money-market accounts right now, so the reserve can earn while it waits. The point isn’t yield. It’s that the cash is liquid and ready the day you need it.
A cash reserve is the difference between a bad week and a bad year. The owners who never sweat payroll built the buffer on purpose, during the good months, before they needed it. See how owners at the OwnerExchange table run their cash →
When and how to use a line of credit
A line of credit is one of the most useful and most misused tools in practice finance. Used right, it’s a bridge. Used wrong, it’s a slow leak.
The right job for it is short-term and temporary. A slow season. A payroll run that lands the week before a big batch of receivables clears. A bulk inventory buy that earns a discount worth more than the interest. You draw what you need, pay interest only on the outstanding balance, and repay as the cash comes in. It’s the most flexible working-capital tool there is, which is exactly why it fits these timing gaps so well.
The wrong job for it is funding losses or long-term assets. If the line is covering ongoing shortfalls month after month, that’s not a timing problem, it’s a profitability problem, and more borrowing only buys time. And a long-term asset, a build-out or a major imaging purchase, belongs on term financing matched to the life of the asset, not on a revolving line.
The smart move is to set up the line before you need it, while the practice looks strong to a lender, and then leave it sitting there unused. A line you arranged in a calm month is a safety net. A line you’re begging for in a crisis is a much harder conversation.
Seasonality and the tax-timing piece
Cash flow isn’t a flat line across the year, and pretending it is creates half the crunches owners hit. Most practices have predictable rhythms, busier and slower stretches, while the big costs like payroll and rent don’t politely shrink when revenue dips.
The fix is to expect it. Map your own pattern from last year’s monthly numbers, build the reserve during the strong months specifically so it’s there for the lean ones, and keep the line of credit ready to bridge the predictable slow weeks instead of being surprised by them every single year.
Tax timing belongs in the same conversation, because a large equipment purchase is both a cash event and a tax event. Section 179 lets a practice expense qualifying equipment in the year it’s placed in service, with a 2026 deduction limit of $2,560,000 and a phase-out beginning at $4,090,000 of purchases, per the latest figures. Bonus depreciation runs alongside it at 100 percent for qualifying property placed in service after January 19, 2025.
Here’s the cash-flow point, not the tax-advice point. A deduction reduces your tax bill, but the equipment still costs real cash the day it arrives. So time the purchase where it helps both: a year you have the cash or the financing to absorb it, and a year the deduction actually does you good. That coordination is exactly the kind of call worth running past your accountant before you sign.
A simple 13-week cash forecast
Everything above gets easier with one humble tool: a rolling 13-week cash forecast. It’s the same instrument turnaround advisors and fractional CFOs have leaned on for decades, and it’s well within reach for any practice.
The idea is plain. You project your expected cash in and cash out, week by week, for the next quarter, about 13 weeks of operations. Then you make it rolling: each week you drop the week that just finished and add a fresh week to the end, so you’re always looking 13 weeks ahead. Most disciplined operators spend about two hours updating it on a Monday.
Keep the first build genuinely simple.
- List your cash in by week. Realistic collections, not booked revenue, since the gap between the two is the whole point.
- List your cash out by week. Payroll, rent, inventory orders, loan payments, taxes, the predictable disbursements.
- Run the running balance. Start with today’s cash, then carry each week’s net forward. The week the balance dips toward zero is the one to manage now.
That’s the entire payoff. The forecast surfaces a tight week weeks in advance, while you still have room to accelerate collections, lean on supplier terms, delay a discretionary buy, or tap the line. It turns cash management from a monthly fright into a quiet weekly habit, which is exactly how the calmest owners run.
What is OwnerExchange?
OwnerExchange is a private peer community for the sharpest 5% of independent veterinary practice owners: 3+ doctor practices doing $3 to $10 million and up. You join a small, caliber-matched mastermind POD led by a veterinary thought leader, plus a private 24/7 forum of owners who already know what a healthy reserve, a clean forecast, and a well-run line of credit look like. No fluff, no vendors, no noise. A new group of just 12 owners is forming now.
The metrics to watch, and where to start
You don’t need a finance degree to stay ahead of cash. You need a short list of numbers and the discipline to glance at them.
Days of cash on hand. Your reserve, translated into time. How many days could you operate if revenue stopped? Track the trend, not just the figure.
Accounts receivable aging. What you’re owed, sorted by how late it is. A creeping balance over 60 or 90 days is usually the first sign cash is leaking.
Inventory as a percent of revenue. Your shelf, in cash terms. Drugs and supplies running well above the 10 to 12 percent reference range, or total COGS above the low 20s, often means money is stuck in stock.
Operating reserve in months. The buffer itself. Know the number, and know whether it’s growing or shrinking.
If this feels like a lot, start with one move this week: open the reserve account and automate the first transfer. Then build the 13-week forecast next month. Cash discipline isn’t a single heroic fix. It’s a few small habits that compound into never lying awake about Friday’s payroll again.

Frequently asked questions
Why can a profitable veterinary practice still run out of cash?
Because profit and cash are two different things. Profit is revenue minus expenses on paper, recognized when earned under accrual accounting. Cash is the actual money in the account. A growing practice ties up cash in receivables, inventory, and equipment that never shows on the profit line, so you can post a strong month and still be short on payroll day. The faster you grow, the more cash the growth quietly consumes.
How much cash should a veterinary practice keep in reserve?
A common rule is one to six months of operating expenses kept liquid, covering payroll, rent, insurance, and loan payments. Most advisors point multi-doctor practices toward the higher end, often one to three months as a working target. The faster money runs through the practice, the bigger the reserve should be. The point is simple: if you couldn’t see a patient for a month, you could still keep the lights on and pay your team.
What is working capital for a veterinary practice?
Working capital is current assets minus current liabilities, the short-term money your practice has to run day to day. The main current assets are cash, accounts receivable, and inventory; the main current liabilities are accounts payable and short-term debt. Managing it well means collecting faster, not overstocking drugs and supplies, and timing what you pay, so cash isn’t trapped in things that haven’t turned back into cash yet.
What is a 13-week cash flow forecast and does a practice need one?
It’s a simple rolling projection of cash in and cash out, week by week, for the next quarter. Each week you add a new week to the end so you always see 13 weeks ahead. For a multi-doctor practice it’s the cheapest early-warning system there is: it flags a tight week weeks before it arrives, while you still have time to accelerate collections, delay a discretionary payment, or draw on a line of credit.
When should a veterinary practice use a line of credit?
A business line of credit is built for short-term, temporary gaps, such as a slow season, a payroll cycle that lands before receivables clear, or a bulk inventory buy. You draw what you need, pay interest only on the balance, and repay as cash comes in. It’s the wrong tool for funding ongoing losses or a long-term asset like a build-out or major equipment, which belong on term financing instead.
What cash-flow metrics should a practice owner watch?
Watch days of cash on hand, accounts receivable aging, inventory as a percent of revenue, and your operating cash reserve in months of expenses. As reference points, AAHA’s Pulsepoints put drugs and medical supplies around 10 to 12 percent of revenue and total cost of goods near 20 to 22 percent. High receivables or a creeping inventory line are usually the first place cash is leaking.
