How to set up a chart of accounts (small business guide)
Your chart of accounts is the backbone of your bookkeeping — the organized list of every category your money flows through. Get it right and your financial statements are clear and your taxes are easier; get it cluttered and every report becomes a guessing game. Here is how to build a clean one.
What it is: a chart of accounts (COA) is simply the master list of buckets your transactions get sorted into. Every sale, bill and transfer lands in one account, and those accounts roll up into your balance sheet and profit-and-loss statement.
The five account types
Every account belongs to one of five categories. The first two build your balance sheet; the last three build your profit-and-loss.
- Assets — what you own: bank accounts, accounts receivable, equipment, inventory.
- Liabilities — what you owe: credit cards, loans, accounts payable, sales tax collected.
- Equity — the owner's stake: contributions, draws, retained earnings.
- Revenue — what you earn: sales, service income, other income.
- Expenses — what you spend to operate: rent, wages, software, supplies, fees.
How to build it, step by step
1. Start from your accounting software's default
QuickBooks, Xero and Sage all ship with a standard chart of accounts for your business type. Start there rather than from a blank page — it is easier to trim than to build.
2. Tailor it to how you actually operate
Add the few revenue and expense accounts that match your real business, and remove ones you will never use. A consulting firm and a restaurant need very different expense accounts.
3. Keep it as lean as it can be
Resist making an account for every tiny thing. If you will not make a decision based on seeing a category on its own line, it probably belongs grouped with something else. Fewer, meaningful accounts beat dozens of near-empty ones.
4. Use a consistent numbering scheme
A common convention: 1000s for assets, 2000s for liabilities, 3000s for equity, 4000s for revenue, 5000s+ for expenses. Numbering keeps reports ordered and makes room to add accounts later without reshuffling.
5. Separate the things you will need at tax time
Give sales tax (GST/HST), owner draws and contributions, and any category with special tax treatment their own accounts so year-end is a hand-off, not an excavation.
Common mistake: lumping different things into one account (all "miscellaneous"), or splitting one thing across many. Both make your statements lie to you. When in doubt, ask: "will I ever want to see this number by itself?"
Set it once, then leave it mostly alone
A good chart of accounts is stable. Renaming or merging accounts mid-year breaks the comparison between this month and last, so plan the structure up front and only add accounts as the business genuinely changes.

Frequently asked questions
What is a chart of accounts?
It is the organized master list of every category your business's transactions are recorded into — assets, liabilities, equity, revenue and expenses — which roll up into your balance sheet and profit-and-loss statement.
How many accounts should a small business have?
As few as give you a clear picture. Most small businesses run well on a few dozen well-chosen accounts. The test is whether you would make a decision based on seeing a category on its own line; if not, group it.
Should I use account numbers?
They help. A simple scheme — 1000s assets, 2000s liabilities, 3000s equity, 4000s revenue, 5000s+ expenses — keeps reports ordered and leaves room to add accounts later without reshuffling everything.
