Setting Up Your Chart of Accounts: A Practical Guide
Best Practices · 2026-02-03 · 6 min
Your chart of accounts is the foundation of your financial reporting. Too few categories and you lack visibility. Too many and you drown in detail. Here is how to find the right balance.
The chart of accounts is a list of every category where money can be recorded in your accounting system. It includes asset accounts (cash, receivables, equipment), liability accounts (payables, loans, credit cards), equity accounts (owner investment, retained earnings), revenue accounts (sales, service income), and expense accounts (rent, utilities, payroll).
Most small businesses need 20-40 accounts total. The default chart of accounts in most accounting software is a reasonable starting point. Resist the urge to create highly specific sub-categories from the start — you can always split a category later, but consolidating dozens of categories is painful.
The most common mistake is creating too many expense categories. You do not need separate accounts for pens, paper, toner, and staples — office supplies is sufficient. Similarly, you do not need separate categories for Slack, Zoom, and Google Workspace — software subscriptions covers all of them unless you need vendor-level tracking.
Design your chart of accounts around the questions you want to answer. If you want to know total marketing spend, create a marketing category. If you want to know online vs offline marketing spend, create two categories. If you need to know the exact cost of each marketing channel, create subcategories. Match the granularity to your reporting needs.
