Bookkeeping Basics
Bookkeeping
Recording and organizing every financial transaction so your reports are accurate.
Why it matters: Your P&L, your KPIs, and your tax filings are only as good as this step.
Bookkeeping vs Accounting
Bookkeeping records and organizes the numbers. Accounting interprets them, plans for taxes, and advises on strategy.
Why it matters: Your CPA can’t fix a messy ledger. Clean bookkeeping is what makes their advice useful. Read more: Veterinary Bookkeeping vs Accounting.
Chart of Accounts
The list of categories every dollar is sorted into, such as revenue, cost of goods sold, payroll, and overhead.
Why it matters: A generic chart puts all revenue in a line or two. A veterinary chart separates exams, diagnostics, pharmacy and procedures, so you can see what drives profit. Read more: Veterinary Chart of Accounts Explained.
AAHA/VMG Chart of Accounts
A standard chart of accounts for veterinary practices, named for AAHA and Veterinary Management Groups (VMG).
Why it matters: A shared structure makes your numbers easier to compare with benchmarks and easier for any new bookkeeper or CPA to read.
General Ledger
The master record of every transaction, organized by account. Your financial statements are built from it.
Why it matters: If the ledger is wrong, every report built on it is wrong too.
Categorization
Assigning each transaction to the right account.
Why it matters: A drug invoice belongs in inventory and cost of goods sold, not in office supplies. Small coding choices change your margins.
Reconciliation
Matching your books to your bank, credit card, and loan statements, and matching your recorded revenue to what your practice software reports.
Why it matters: This is where gaps, double entries, and missing deposits get caught.
Month-end Close
The routine of finishing a month’s books: reconcile, adjust, review, then produce the financial statements.
Why it matters: A close that lands in the first weeks of the next month gives you reports while you can still act on them.
Catch-up Bookkeeping
Bringing books current when they are behind or came from an older system.
Why it matters: You can’t plan from numbers that are months old. Catch-up work gives you a clean starting line.
Cash vs Accrual Accounting
Cash accounting records income and expenses when money moves. Accrual accounting records them when they are earned or incurred.
Why it matters: Cash shows what is in the bank. Accrual shows how the practice performed. Most hospitals use accrual for management reporting and lean on cash flow views for planning. Read more: Accrual vs Cash Accounting for Veterinary Hospitals.
Veterinary-specific bookkeeping to help you achieve clean books and predictable cash flow.
Revenue, Doctors and Payroll
Production
The value of the services a doctor performs in a period, as invoiced to clients.
Why it matters: Production is a performance measure. It is not a payroll expense, and mixing the two up is a common source of confusion. Read more: How to Track Associate Veterinarian Production in Your Books.
Collections
The money actually received for services.
Why it matters: Production and collections rarely match in a given month. Knowing which one you are looking at keeps you from misreading the numbers.
Production-based Pay
Doctor compensation calculated as a share of production, sometimes on top of a base salary.
Why it matters: Pay follows work with a delay, so a strong month of production can show up as higher payroll in the next one.
Service Mix
How your revenue splits across exams, surgery, diagnostics, pharmacy, preventatives, and retail.
Why it matters: Each category has different margins. Separate revenue accounts show you what is really driving growth.
Practice Management Software (PMS)
The system that runs daily operations: appointments, medical records, invoicing and inventory movement.
Why it matters: Your PMS tracks what happened in the exam room. Your accounting system tracks what happened in the bank. Bookkeeping reconciles the two.
Payroll Allocation
Assigning payroll costs to the right labor accounts, such as doctors, technicians, and administrative staff.
Why it matters: Without it, payroll shows up as one big number and you can’t see where labor costs are really coming from.
Payroll as a Percentage of Revenue
Total payroll divided by total revenue, often called the labor percentage.
Why it matters: It is one of the quickest checks for staffing and compensation sustainability, but only if payroll is categorized clearly in your books.
1099 Preparation
Reporting payments made to independent contractors, such as relief veterinarians, to the IRS at year-end.
Why it matters: Clean vendor records through the year make this a routine task instead of a scramble.
Inventory and Costs
Cost of Goods Sold (COGS)
The direct costs of providing patient care: pharmaceuticals, medical and surgical supplies used in procedures, and external lab fees tied to diagnostics.
Why it matters: COGS should rise and fall with clinical activity. When it is mixed into overhead, your margins stop telling the truth. Read more: COGS vs Operating Expenses in Veterinary Bookkeeping.
Operating Expenses
The costs of running the hospital regardless of patient volume, such as rent, utilities, marketing, software and professional fees. Payroll is often shown on its own line.
Why it matters: Separating these from COGS shows whether profit pressure comes from purchasing, pricing or overhead.
Inventory
The products you hold for use or sale, such as medications, supplies, and preventatives. It is recorded as an asset when purchased and becomes an expense only when it is used or sold.
Why it matters: Cash leaves when you buy inventory, but the expense shows up later. That gap is one of the biggest reasons profit and cash don’t match. Read more: The Correct Way to Track Inventory Costs in a Veterinary Hospital.
Inventory Turnover
How quickly you use or sell through your inventory.
Why it matters: Slow turnover means cash sitting on the shelf, and expired product waiting to become a loss.
Shrink
Inventory lost to expiration, waste, theft, or use that was never recorded.
Why it matters: Shrink hides inside your margins. You see thinner margins without an obvious cause.
Gross Margin
Revenue minus COGS, usually shown as a percentage of revenue.
Why it matters: It is one of the clearest signals of pricing, purchasing, and service mix. A sudden swing usually points to inventory timing or categorization, not a business problem.
Medical Supply Invoice Categorization
Coding each line of a vendor invoice to the right inventory or COGS account.
Why it matters: Medical supply invoices are some of the most frequent and most misclassified transactions in a hospital. Getting them right keeps COGS clean.
Veterinary Bookkeeping Hubs
Reports and Statements
Financial Statements
The set of reports your books produce each month: usually the profit and loss statement, the balance sheet and a cash flow view.
Why it matters: They are the product of all the bookkeeping behind them. If they arrive late or change format, decisions suffer.
Profit and Loss Statement (P&L)
A report of revenue, costs and profit over a period. Also called the income statement.
Why it matters: It answers one question: how did the practice perform? Read it as a trend across months, not as a single verdict. Read more: How to Read a Veterinary Profit & Loss Statement.
Balance Sheet
A snapshot of what the practice owns, what it owes, and what is left for the owners on a given date.
Why it matters: Inventory, equipment loans, and cash all live here. Many owners look only at the P&L and miss what the balance sheet shows.
Cash Flow Statement
A report of where cash came from and where it went during a period.
Why it matters: It explains the timing gaps that make a profitable month feel tight.
Net Profit and Net Profit Margin
Net profit is what remains after all expenses. Net profit margin shows it as a percentage of revenue.
Why it matters: Profit is not cash. A strong net profit can sit next to a low bank balance if cash is tied up in inventory or paid out in debt service.
KPI (Key Performance Indicator)
A metric you review on a regular schedule to judge how the practice is doing. Common veterinary examples are gross margin, payroll as a percentage of revenue, and inventory as a percentage of revenue.
Why it matters: A few KPIs reviewed monthly beat a dashboard of dozens. They only work when the books behind them are structured correctly. Read more: Veterinary KPIs Every Practice Owner Should Review Monthly.
We’ll show you exactly how to bring clarity, cash flow visibility, and control to your practice.
Cash Flow, Growth, and Valuation
Cash Flow
The movement of money into and out of the practice over time.
Why it matters: Profit and cash are different things. Cash flow shows where your money is actually going. Read more: Cash Flow Problems in Veterinary Practices.
Timing Gap
The delay between when something is recorded in your books and when the cash actually moves.
Why it matters: Inventory is paid for before it is used, doctors are paid after production, and taxes arrive after income. These gaps explain most cash flow surprises.
Debt Service
The loan payments, principal and interest, that a practice makes on equipment, real estate, or acquisition financing.
Why it matters: Debt service draws cash steadily, whether the month was strong or slow.
Depreciation
Spreading the cost of a long-lasting asset, such as imaging equipment, over the years you use it.
Why it matters: It shows up as an expense on your P&L without cash leaving that month, which is another reason profit and cash drift apart.
Owner Distributions
Money an owner takes out of the practice as profit, separate from salary.
Why it matters: A safe distribution depends on cash, not just on net profit. Ask your CPA about the tax side.
EBITDA
Earnings before interest, taxes, depreciation, and amortization. Buyers and lenders commonly use it to compare and value practices.
Why it matters: If your books are inconsistent, your EBITDA is hard to trust, and so is any valuation built on it.
Adjusted EBITDA
EBITDA after removing one-time items and normalizing costs that are specific to the current owner, such as owner pay that is above or below market.
Why it matters: This is the figure sale conversations usually focus on. Clear records make the adjustments easy to support.
Due Diligence
The review a buyer or lender does of your financials and records before a deal closes.
Why it matters: Messy books slow the process and reduce confidence. Clean, consistent books shorten it. Read more: What Veterinary Buyers and Lenders Look for in Financials.
