Quick answer: If your practice books rent, owner salary, or depreciation as annual lump sums — usually in December — your monthly P&L is useless for decision-making 11 months of the year. One month looks catastrophic. The other 11 look artificially good. Neither is real. The fix takes your accounting team 15 minutes.

The December That Lost $110,000

A veterinary practice we recently analyzed showed strong, consistent monthly profits from April through November. Net income ranged from $17,000 to $74,000 every month. Revenue was steady. Expenses were predictable. Everything looked healthy.

Then December hit: negative $110,000.

Not a dip. A six-figure loss. In a single month. On a practice that was profitable every other month of the year.

If you were the owner and you looked at that December P&L without context, you'd panic. You might freeze hiring. Delay equipment purchases. Cancel the marketing campaign you were considering. Pull back on everything because the numbers just told you the business lost $110,000 in 30 days.

Except it didn't. The practice was fine. December was a normal operating month. The $110,000 "loss" was entirely a bookkeeping artifact — created by catch-up journal entries that dumped 12 months of expenses into a single period.

Here's what was booked in December:

Every one of these expenses was real. The practice owed that rent, that salary, that depreciation. But by booking them all in December instead of ratably across 12 months, the P&L for January through November was understating expenses — and the December P&L was massively overstating them.

Neither picture was accurate.

Key Takeaway: If your practice books rent, owner salary, or depreciation as annual lump sums in December, your monthly P&L is fiction 11 months of the year. The annual total doesn't change — but you can't make hiring, pricing, or investment decisions on distorted monthly data. The fix is 15 minutes of recurring journal entries in QuickBooks.

Why This Happens (And Why It's So Common)

This isn't a mistake unique to one practice. We see this pattern in veterinary clinics, dental offices, medical practices, and service businesses across South Florida. The cause is almost always the same: the practice runs on cash-basis thinking even when the books are set to accrual.

Here's how it typically plays out:

The owner pays rent monthly. The check goes out on the 1st of every month. But the bookkeeper either isn't recording it, or is recording it to a suspense account, or is waiting for some reconciliation that never happens. At year-end, the accountant cleans it up with a single entry.

The owner doesn't set up formal payroll for themselves. Instead of running officer salary through payroll monthly, they take draws. At year-end, the accountant books a journal entry to reclassify draws as officer compensation — often as a single December entry.

Depreciation is calculated once a year. The accountant computes the annual depreciation figure during tax prep and books it as a single December entry instead of 1/12 each month.

Bonuses are paid annually. They show up as a December expense because that's when the check was cut.

In every case, the entries are technically correct — the annual totals tie out. But the monthly distribution is fiction.

What It Costs You (Beyond Confusion)

Distorted monthly financials don't just look ugly. They lead to real decision-making errors.

You can't see seasonal patterns. If $135,000 in rent is sitting in December, your operating cost for every other month is understated by $11,250. That means your margin for April through November looks better than it is. You might think you have room to hire, expand, or invest when you actually don't — or at least not as much as the numbers suggest.

You can't benchmark against industry standards. When you compare your monthly P&L to AAHA or VHMA benchmarks, the distortion throws everything off. Your rent-to-revenue ratio looks like 0% for 11 months and 95% in December. Neither number is useful for comparison.

You can't spot real problems. If a genuine cost increase happens — say your lab fees spike by $3,000 in September — it gets lost in the noise. The monthly P&L is already wrong, so an additional $3,000 doesn't trigger any alarm. You don't catch it until the annual review, if at all.

You can't forecast cash flow. Cash flow forecasting depends on understanding your true monthly burn rate. If your books say you spend $55,000/month in operations for 11 months and then $270,000 in December, any forecast built on those numbers is garbage.

You can't get a fair practice valuation. If you ever sell, merge, or bring in a partner, the buyer's due diligence team will normalize your financials. They'll catch the lump-sum entries and may use them as a negotiating point — not because you did anything wrong, but because messy books signal a practice without financial infrastructure. That costs you at the negotiating table.

The Fix Takes 15 Minutes

This is not a complex accounting problem. Your accounting team can fix it in a single sitting.

Step 1: Identify every annual lump-sum entry. Pull your December journal entries and flag everything that represents a full-year expense booked in one month. Common culprits: rent, owner salary, depreciation, insurance, property taxes, annual subscriptions, and bonuses.

Step 2: Convert each one to a monthly recurring entry. For rent at $135,000/year, create a recurring monthly journal entry for $11,250. For officer salary at $125,000/year, book $10,417/month. For depreciation at $6,560/year, book $547/month.

Step 3: Set it up in QuickBooks (or your accounting system). QuickBooks Online supports recurring journal entries. Set them to post automatically on the 1st of each month. Once configured, they run without anyone touching them.

Step 4: Reverse the catch-up approach going forward. Make it a policy: no annual lump-sum entries for recurring expenses. If an expense happens every month, it gets booked every month.

Here's what the monthly P&L looks like before and after this fix, using the practice we analyzed:

The annual total doesn't change. The practice still earns $418,000 for the year. But now the monthly numbers actually mean something. You can see which months are stronger, which are weaker, and whether your costs are trending up or down — in real time, not in a year-end surprise.

The Deeper Issue: Are You Running Your Practice on Real Numbers?

The catch-up entry problem is a symptom of a bigger question: how current and accurate is the financial information you use to make decisions?

If your books are only "correct" once a year — after the annual cleanup — then you've been making 11 months of decisions on incomplete data. Hiring decisions. Pricing decisions. Expansion decisions. Draw decisions. All based on numbers that don't reflect reality.

We see practice owners who think they're running at 8% occupancy cost because the monthly P&L shows zero rent. They're actually running at 11%. That's not a small difference — on a $1.6M practice, it's the difference between $128,000 and $176,000 in annual occupancy cost. That $48,000 gap is real money, and it was invisible until someone cleaned up the entries.

The practices that make the best financial decisions — the ones that grow profitably, build cash reserves, optimize their tax position, and eventually sell at premium multiples — are the ones with clean books twelve months a year. Not because they're accounting obsessives. Because accurate monthly data is the foundation for every good business decision.

This is the difference between an accounting firm that files your taxes and one that helps you run your business. Most firms see a clean annual return and call it done. We look at your monthly financials and ask: can you actually make decisions with these numbers? If December looks nothing like January, the answer is no — and we fix it before you make a hiring decision on bad data.

What To Do This Week

1. Ask your accountant one question: "Are there any expenses being booked as annual lump sums instead of monthly?" If they hesitate or say "we true it up at year-end," you've found the problem.

2. Pull your December P&L. Look for any line item that's dramatically different from the other 11 months. That's your catch-up entry.

3. Request monthly recurring entries for every recurring expense. Rent, owner salary, depreciation, insurance, property taxes. If it happens every month, book it every month.

4. Compare January and February to the corrected baseline. Once the recurring entries are in place, your January and February financials become reliable for the first time. Use them.

This isn't about being a perfectionist. It's about having the information you need to run your practice — not once a year, but every month.

If your monthly P&L has numbers you don't trust — or if December looks nothing like the rest of the year — we'll clean it up. One conversation identifies every catch-up entry. We set up monthly accruals, and from that point forward, your financials tell the truth every month — not just in April when the tax return is done. Schedule a financial cleanup →

Frequently Asked Questions

Is it wrong to book expenses as annual lump sums?

It's not illegal and it doesn't affect your annual tax return. The annual totals are the same either way. But it makes your monthly financial statements unreliable for operational decision-making. If you use monthly P&Ls to make hiring, pricing, or investment decisions — and you should — lump-sum entries undermine that process.

What's the difference between cash basis and accrual basis for monthly reporting?

Cash basis records income and expenses when cash changes hands. Accrual basis records them when they're earned or incurred, regardless of when cash moves. For monthly reporting, accrual basis with proper monthly entries gives you a much more accurate picture of your practice's true performance. Your tax return may use either method, but your internal management reports should use accrual.

How do I know if my accountant is booking catch-up entries?

Look at your December P&L. If any expense category is dramatically larger in December than in other months — especially rent, officer salary, depreciation, or insurance — it's likely a catch-up entry. You can also ask your accountant directly: "Are there any recurring expenses that aren't being booked monthly?"

Will fixing this change my tax liability?

No. The annual totals remain identical. Switching from annual lump-sum entries to monthly recurring entries is purely an internal reporting change. Your taxable income for the year is the same. The only thing that changes is the accuracy of your monthly financial statements.
