Vet Bookkeeping Is Mostly About Inventory

The biggest single difference between veterinary practice bookkeeping and general small business bookkeeping is the inventory. Vet practices carry significant pharmacy inventory (drugs, vaccines, flea and tick prevention, heartworm products), surgical supplies, retail food and pet products, and lab consumables. The cost of goods structure for a vet practice can easily run 20 to 30% of revenue, and most of that flows through inventory rather than directly as expense.

Setting up the books to handle inventory correctly is the difference between a P&L that tells you about practice profitability and one that just hopes the numbers balance at year end. This post walks through the practical bookkeeping setup for a Texas vet practice.

Chart of Accounts for a Veterinary Practice

The chart of accounts should reflect the practice's revenue mix and the inventory complexity.

Revenue Accounts

  • Veterinary Service Revenue (or split by exam, surgery, dental, diagnostics)
  • Pharmacy Revenue (drugs and prescriptions dispensed)
  • Vaccine Revenue
  • Boarding Revenue (if the practice boards)
  • Grooming Revenue (if the practice grooms)
  • Retail Revenue (food, treats, accessories)
  • Lab Revenue (in house lab work)
  • Imaging Revenue (radiology, ultrasound)

Practices vary in how granular this should be. Mixed practices doing meaningful boarding or grooming benefit from breaking those out so the P&L can show whether those service lines are actually profitable. Many small animal practices that do not board can use a simpler structure.

Cost of Service / Cost of Goods Sold Accounts

  • Pharmacy Cost of Goods Sold (drug inventory expensed as dispensed)
  • Vaccine Cost of Goods Sold
  • Surgical Supplies
  • Medical Supplies (general clinical consumables)
  • Lab Supplies
  • Boarding Supplies (if applicable)
  • Grooming Supplies (if applicable)
  • Retail Cost of Goods Sold (food, treats expensed as sold)

The pharmacy COGS account is the largest one for most vet practices. Tracking it as a separate line lets you see drug margin (the markup on what is dispensed) at a glance.

Operating Expense Accounts

  • Wages and Payroll Taxes
  • Employee Benefits
  • Rent or Mortgage Interest
  • Utilities
  • Telephone and Internet
  • Practice Management Software (Cornerstone, AVImark, ezyVet, Provet, Hippo Manager)
  • Marketing and Advertising
  • Continuing Education
  • Professional Memberships (TVMA, AVMA, AAHA)
  • Malpractice Insurance
  • General Liability Insurance
  • Office Supplies
  • Repairs and Maintenance
  • Depreciation Expense

Balance Sheet Accounts

  • Operating Cash Account
  • Reserve / Savings Account
  • Accounts Receivable (most vet revenue is collected at the time of service, so this is often smaller than in human medical practices)
  • Pharmacy Inventory
  • Vaccine Inventory
  • Retail Inventory
  • Surgical Supplies Inventory (if tracked separately)
  • Fixed Assets (Equipment, Furniture, Build Out)
  • Accumulated Depreciation
  • Accounts Payable
  • Credit Cards Payable
  • Loans Payable
  • Owner Equity

Adjustments and Write Offs

  • Pet Insurance Adjustments (if applicable; most vet practices do not contract with pet insurance directly, but some are starting to)
  • Patient Adjustments (employee discounts, professional courtesy, rescue and shelter discounts)
  • Bad Debt Expense

Inventory: The Most Important Bookkeeping Topic in a Vet Practice

The biggest single mistake in vet practice bookkeeping is treating inventory purchases as immediate expense rather than tracking through inventory and COGS. This mistake distorts both the P&L and the balance sheet meaningfully because vet practice inventory is so large.

How It Should Work

When you receive a shipment from your drug distributor:

  • The cost posts to Pharmacy Inventory (balance sheet asset)
  • The bank account decreases by the same amount (or the A/P increases if the invoice has not been paid yet)

When you dispense product to a client:

  • The cost of the dispensed product posts to Pharmacy COGS (P&L expense)
  • The Pharmacy Inventory decreases by the same amount
  • The revenue from the client posts to Pharmacy Revenue (P&L)

Done correctly, the books show pharmacy inventory as a balance sheet asset that fluctuates with purchases and dispensings, and the P&L shows pharmacy revenue and pharmacy COGS that net to the margin on dispensed product.

What Most Practices Actually Do

Many vet practices post the full invoice from the drug distributor directly to a Pharmacy Cost expense account at the time of purchase. This:

  • Overstates expense in the month of purchase
  • Understates inventory on the balance sheet
  • Misrepresents the P&L during inventory buildup or drawdown
  • Hides inventory loss from expiration or refrigeration failure

The fix is to set up Pharmacy Inventory as a balance sheet account and adjust at month end to match the physical inventory count.

Vaccine Inventory Specifically

Vaccines are typically the most refrigeration sensitive inventory in a vet practice. Refrigeration failures, expired product, and lost product are all common. The accounting should reflect these losses.

Refrigerated inventory losses post as:

  • Reduction of Vaccine Inventory (balance sheet)
  • Increase to a Vaccine Loss expense account (P&L)

Practices that do not track these losses end up with inventory balances on the books that do not match what is actually in the refrigerator.

Retail Inventory

Food and retail product is sometimes overstocked. Tracking retail inventory through COGS lets the practice see whether retail is a profit center or just shelf space funded by operating cash.


Equipment Depreciation

Vet equipment includes diagnostic imaging, surgical equipment, in house lab, dental units, and boarding facility equipment. The bookkeeping treatment is:

  1. Equipment purchase posts to Fixed Assets (balance sheet)
  2. Depreciation Expense posts to the P&L over time

Section 179 and bonus depreciation can accelerate the tax deduction. Our Section 179 vs bonus depreciation post covers the tax side.


The Monthly Close

A good monthly close for a vet practice produces:

  • Reconciled bank and credit card statements
  • Pharmacy inventory adjusted to physical count
  • Vaccine inventory adjusted to physical count and dispensing records
  • Retail inventory adjusted to physical count
  • Inventory losses (expiration, refrigeration failure) recorded as expense
  • Owner compensation recorded correctly
  • Loan principal and interest split correctly
  • Depreciation entries
  • Reviewed P&L and balance sheet

Common Vet Bookkeeping Mistakes

Treating Drug Distributor Invoices as Immediate Expense

The biggest single mistake. Inventory purchases are balance sheet items. Expense them as dispensed through COGS.

Not Tracking Vaccine Loss

Refrigeration failures, expirations, and damaged product all produce real losses. Practices that do not track them have inventory balances that overstate practice assets.

Mixing Pharmacy and Medical Supplies in One Account

Pharmacy (dispensed drugs) and medical supplies (clinical consumables) have different margin profiles. Tracking them separately produces a more useful P&L.

Recording Equipment Purchases as Expense

Equipment is a fixed asset. Depreciation is the expense. The two are separate.

Not Tracking Boarding and Grooming Separately

For practices that board and groom, knowing whether those service lines are profitable requires separate tracking.

Mixing Personal and Practice Expenses

Owner personal expenses through the practice card create messy books.

Skipping the Monthly Close

Accumulating transactions for year end cleanup is more expensive than monthly close.


Frequently Asked Questions

Should I count inventory monthly?

Most successful vet practices count pharmacy inventory at least monthly, more often for vaccines and high value items. Yearly counts are inadequate; the variance between expected and actual ending inventory is too large.

Cash basis or accrual basis?

The IRS generally requires accrual basis for businesses with meaningful inventory (which includes most vet practices). Talk to your tax advisor about the specific rules for your practice size.

Should I track each drug by SKU in my books?

The practice management software typically tracks dispensings by SKU. The books usually do not need that level of detail. The books need to reflect the total pharmacy inventory balance, with the SKU level detail living in the practice management system.

Do I need to do a physical count or can I trust the software?

Both. Practice management software estimates inventory based on purchases and dispensings. Physical counts catch shrinkage, miscounts, and process problems. The variance between software inventory and physical count is itself a useful management number.

How often should I reconcile?

Monthly. Larger practices benefit from weekly bank reconciliations.

Should I outsource bookkeeping?

Most vet practices benefit from outsourcing to someone familiar with vet bookkeeping. The inventory complexity, particularly vaccines and pharmacy, is easier with someone who has seen the patterns.


Getting Vet Practice Bookkeeping Right

The vet practices that consistently know what is happening financially are the ones with proper inventory tracking, separate accounts for the different service lines, and a monthly close that includes physical inventory counts. The practices that struggle usually have inventory expensed at purchase, no physical counts, and books that have not been reconciled in months.
