Chart of Accounts
Also known as: COA
A chart of accounts is the master list of every category your business records money into — each income, expense, asset, liability, and equity bucket.
What it actually means
The chart of accounts is the filing system your books are built on. Every transaction is assigned to one of its accounts, and every report — profit and loss, balance sheet — is those accounts summed and arranged. A good chart is specific enough to answer real questions and short enough to stay consistent: separate lines for the costs you actively manage, one bucket for everything minor. The common failure is sprawl, where near-duplicate categories accumulate until the same expense lands in three places and the reports stop meaning anything. Setting it up deliberately at the start saves years of ambiguity later.
A detail shop might run separate expense accounts for supplies, equipment, rent, payroll, and advertising — with advertising split by channel.
If advertising is a single line, you can't tell what Meta cost you versus Google versus print. Splitting ad spend into its own accounts by channel is what turns a P&L into something you can judge marketing decisions from.
