Chart of Accounts
Definition
A chart of accounts is the organized listing of every account in a company's general ledger, categorized into assets, liabilities, equity, revenue, and expenses. It serves as the structural framework for all financial recording and reporting, and a well-designed chart of accounts makes financial analysis and tax preparation significantly easier.
Overview
The chart of accounts (COA) is the backbone of a company's bookkeeping system. Every financial transaction is recorded into one of the accounts in the COA, which are organized into five major categories: assets, liabilities, equity, revenue, and expenses. Each account is assigned a unique number and name.
For startups, a thoughtful COA design from the beginning saves enormous time later. Key principles include: keeping it simple but specific enough to answer important questions (e.g., separating "Engineering Salaries" from "Sales Salaries"), aligning with your P&L reporting structure so financial statements are easy to generate, and including accounts that match investor and board reporting expectations.
A common mistake is creating either too few accounts (making it impossible to analyze spending by category) or too many (creating unnecessary complexity and inconsistent categorization). A typical seed-stage SaaS company needs roughly 30 to 50 accounts. The COA should be reviewed annually and updated as the business evolves.
Example
A SaaS startup COA might include: 1000-Cash, 1100-Accounts Receivable, 2000-Accounts Payable, 3000-Common Stock, 4000-Subscription Revenue, 5000-Hosting Costs, 6100-Engineering Salaries, 6200-Marketing Spend.
