Why a Profitable Veterinary Practice Can Still Run Out of Cash

A practice can show a healthy profit on its year-end financials and still come within a week of missing payroll. That's not a bookkeeping error. It's the gap between profit and cash, and most owners don't understand it until they're looking at a bank balance that doesn't match what the P&L told them to expect.

Profit and cash are not the same number

Accrual accounting recognizes revenue when it's earned and expenses when they're incurred, not when the money actually moves. That creates real timing gaps. Revenue sits in accounts receivable before it clears. Loan principal payments reduce cash but don't show up as an expense on the P&L, only the interest portion does. Owner distributions move cash out without touching profit at all.

Vet practices feel this in specific, predictable ways. Payroll runs on a fixed biweekly or semimonthly schedule regardless of how busy that particular week was. Rent and loan payments are due on fixed dates no matter what. A seasonal inventory buy ahead of flea and tick season or spring vaccine season has to be paid for before the revenue from selling it comes in. And a slow month, whatever causes it in your market, still carries the same fixed cost base as a strong one.

Build a rolling cash forecast, not just a budget

An annual budget tells you where you should end up. It doesn't tell you whether you have enough cash on hand three weeks from now to cover payroll and a vendor payment landing the same week. That's what a rolling cash flow forecast is for.

The standard version is a 13-week rolling forecast: start with your actual cash balance today, add expected collections based on your scheduled production for each week, subtract known fixed outflows like payroll, rent, and loan payments, then subtract variable outflows like inventory orders and discretionary spending. Each week, replace that week's estimate with the actual number and roll the forecast forward another week. The result is about three months of visibility instead of a monthly P&L that only tells you what already happened.

A longer monthly version, run out twelve months, is useful for annual planning and for spotting seasonal patterns before they surprise you again next year.

Decide reserves versus a line of credit before you need either

A cash reserve and a line of credit solve different problems, and the practices that get caught off guard are usually the ones that never decided which tool they were relying on.

A reserve is your buffer for normal variability: a common starting point is four to six weeks of fixed operating costs, more if your practice has real seasonality or a capital expense on the horizon. A line of credit is for a genuine timing gap, a seasonal inventory buy that has to happen before the revenue from it arrives, for example, not for a shortfall that shows up every single month. If cash is tight most months rather than a few predictable ones, that's a sign to fix the underlying structure, not to borrow around it.

Apply for a line of credit while the practice is healthy and can qualify comfortably. Lenders want to see stability, not a practice that's already scrambling.

Make it a habit, not a project

A cash forecast loses most of its value if it's built once and never updated. The practices that stay ahead of this treat it as a weekly or monthly discipline tied to their actual books, not a spreadsheet built in a panic. That's the kind of ongoing visibility a fractional CFO relationship and a live dashboard like OneView™ are built to provide, so you're looking at this before a tight week arrives, not during one.
