Bookkeeping Terms Glossary: 50 Terms Every Business Owner Should Know

Accounting has a vocabulary problem: fifty ordinary-sounding words that mean something precise — and expensive to misunderstand. You don't need to speak fluent accountant to run a business, but you do need enough of the language to read your own reports, catch mistakes, and follow the conversation with your bookkeeper. Here are the 50 terms that cover 95% of what you'll encounter, in plain English, grouped the way you'll actually meet them.

What are the everyday basics?

1. Bookkeeping — Recording every transaction, accurately and on time. The raw material for everything else on this page.
2. Accounting — Turning those records into meaning: reports, analysis, tax positions, decisions.
3. Chart of accounts — The master list of categories (accounts) your business sorts money into. Keep it short; bloated charts hide more than they reveal.
4. General ledger — The complete, permanent record of every transaction in every account. The "books" everyone refers to.
5. Journal entry — A manual recording of a transaction, used for things bank feeds can't capture — depreciation, accruals, corrections.
6. Transaction — Any event that moves money or value: a sale, a bill, a transfer, a fee.
7. Debit — An entry on the left side of an account. Increases assets and expenses; decreases liabilities, equity, and revenue. Not "bad."
8. Credit — The right-side entry. Increases liabilities, equity, and revenue; decreases assets and expenses. Not "good."
9. Double-entry bookkeeping — Every transaction hits at least two accounts, and debits must equal credits. The self-checking design that's kept books honest for five centuries.
10. Reconciliation — Matching your books against bank and card statements until they agree. The single habit that catches errors, missed income, and fraud.

Because debits and credits confuse everyone at first, here's the one table worth pinning up:

Which terms explain your profit and loss?

11. Income statement (P&L) — The report showing revenue minus expenses over a period. Answers "did we make money?"
12. Revenue — Money earned from selling goods or services, before any costs. Top line.
13. Cost of goods sold (COGS) — The direct cost of what you sold: materials, direct labor, freight in. Rises and falls with sales.
14. Gross profit — Revenue minus COGS. What's left to cover everything else.
15. Gross margin — Gross profit as a percentage of revenue. The single best gauge of pricing health, tracked over time.
16. Operating expenses — The costs of running the business that aren't COGS: rent, payroll, software, insurance, marketing.
17. Overhead — Operating costs that continue regardless of sales volume — rent doesn't care about your slow month.
18. Net income — The bottom line: revenue minus all expenses. Profit on paper, which is not the same as cash in the bank.
19. EBITDA — Earnings before interest, taxes, depreciation, and amortization. A rough "operating engine" measure lenders and buyers like.
20. Burn rate — How much cash the business consumes per month. Paired with your balance, it tells you the time you have.

Which terms live on the balance sheet?

21. Balance sheet — A snapshot at one moment: what you own, what you owe, and what's left. Assets = liabilities + equity, always.
22. Assets — Everything the business owns with value: cash, receivables, inventory, equipment.
23. Current assets — Assets expected to become cash within a year (cash, AR, inventory).
24. Fixed assets — Long-lived property like equipment, vehicles, and buildings, written off over time rather than expensed at once.
25. Liabilities — Everything the business owes: credit card balances, loans, unpaid bills, taxes collected but not yet remitted.
26. Current liabilities — Debts due within a year (payables, credit cards, this year's loan payments).
27. Long-term liabilities — Debts due beyond a year, like the balance of an equipment loan or SBA note.
28. Equity — Assets minus liabilities: the owners' stake. What would notionally remain if everything were sold and every debt paid.
29. Retained earnings — Accumulated profits kept in the business over its life rather than distributed to owners.
30. Accounts receivable (AR) — Money customers owe you for work already delivered. Revenue you can't spend yet.
31. Accounts payable (AP) — Money you owe vendors for what you've received. Someone else's AR.
32. Working capital — Current assets minus current liabilities. The cushion that determines whether growth feels exciting or terrifying.

What do the cash-flow terms mean?

33. Cash flow — The actual movement of money in and out. Profitable businesses fail from running out of this; it's not a technicality.
34. Cash flow statement — The report reconciling profit to cash, split across operating, investing, and financing activities.
35. Operating cash flow — Cash generated by the core business itself, before loans and asset purchases. The number that should be positive most months.
36. Free cash flow — Operating cash flow minus equipment and asset spending. What's genuinely available for debt, distributions, or growth.
37. Runway — Cash on hand divided by monthly burn: how many months you can operate at the current pace.
38. Accrued expense — A cost you've incurred but not yet paid (December wages paid in January). Books now, cash later.
39. Deferred revenue — Cash collected for work not yet delivered — a deposit or annual prepayment. It's a liability until you earn it.
40. Petty cash — A small managed cash fund for minor expenses. Small, but still reconciled — untracked cash is where books start to rot.

Which method, tax, and year-end terms matter?

41. Cash basis — Record income when received and expenses when paid. Simple, cash-realistic, and how most small businesses file.
42. Accrual basis — Record income when earned and expenses when incurred, regardless of payment timing. Truer performance picture; required in some cases as businesses grow.
43. GAAP — Generally Accepted Accounting Principles: the formal ruleset for financial statements, typically required by lenders and investors before most small businesses need it.
44. Fiscal year — The 12-month reporting year, which doesn't have to match the calendar (though for most small businesses it does).
45. Trial balance — A listing of all account balances proving debits equal credits — the pre-flight check before closing.
46. Closing the books — Finalizing and locking a period so its numbers stop moving. What makes reports trustworthy and tax prep painless.
47. Depreciation — Spreading a physical asset's cost over its useful life — with tax elections (like 2026's 100% bonus depreciation) often accelerating it to year one.
48. Amortization — The same spreading concept for intangibles (software, goodwill) — and, separately, the schedule by which a loan gets repaid.
49. Basis — Your investment in an asset (or your business) for tax purposes. Determines gain when you sell and can cap the losses you may deduct.
50. W-9 and 1099-NEC — The intake form you collect from contractors, and the form you issue in January reporting what you paid them (required for 2026 payments of $2,000 or more).

How do these terms fit together in practice?

A hedged illustration — simplified numbers, ignoring taxes and payroll detail. A café's January: revenue $30,000, COGS $9,000 → gross profit $21,000 (70% gross margin). Operating expenses of $17,000 leave $4,000 net income. Yet the bank balance fell — because $6,000 of catering invoices sit in accounts receivable, and a $3,000 loan payment (mostly principal, so not an expense) went out. Profit says "fine month"; cash flow says "collect those invoices." Neither report is wrong — they answer different questions, which is exactly why owners who read both stop being surprised.

If your reports don't look like that story — if the P&L mixes draws with expenses, or nothing's been reconciled since spring — the vocabulary isn't the problem, the books are, and that's a fixable, flat-fee project. Problems come here to get solved. Our bookkeeping team delivers clean monthly statements with a human who'll explain them, and every rate is public on the pricing page.

FAQ

Why does my bank statement say "credit" when money comes in, but my bookkeeper says deposits are debits?

The bank writes statements from its perspective — your deposit is the bank's liability to you, so they credit it. In your own books, cash is your asset, and receiving money debits it. Same event, opposite vantage points; both correct.

Cash or accrual — which should my business use?

Most small businesses start (and file taxes) on cash basis for simplicity. Switch to accrual views when invoices, inventory, or prepayments make cash-basis reports misleading — many businesses keep accrual books for management and file on a cash basis, which is perfectly legal with the right adjustments.

Which reports should I actually look at monthly?

Three: the P&L (are we profitable?), the balance sheet (what do we own and owe?), and the cash flow statement or an AR aging (where's the money?). Fifteen minutes on those beats an hour of dashboard-staring.

Do I need to follow GAAP?

Generally not until a lender, investor, or acquirer asks. What every business needs from day one is consistency — same categories, same method, every month — so trends mean something.

Is a bookkeeper enough, or do I need an accountant too?

Both, doing different jobs: the bookkeeper keeps the record accurate all year; the accountant turns it into tax strategy and filings. The expensive mistake is having neither and reconstructing a year every April.
