Chart of Accounts for Startups

Your chart of accounts (COA) is the organizational structure for your entire financial data. It's the list of every account where transactions are recorded, grouped by type. Getting this right from the start saves enormous headaches later—and makes it possible to analyze your business effectively.

Every chart of accounts has five main categories:

Assets represent what you own. This includes current assets (cash, accounts receivable, prepaid expenses) and fixed assets (equipment, furniture, computers).

Liabilities represent what you owe. This includes current liabilities (accounts payable, accrued expenses, credit cards) and long-term liabilities (loans, deferred revenue).

Equity represents the owner's stake in the company. For startups, this typically includes common stock, preferred stock, additional paid-in capital (APIC), and retained earnings (or accumulated deficit).

Revenue represents income from sales and services. Consider breaking this into multiple accounts if you have different revenue streams (product revenue, service revenue, etc.).

Expenses represent costs incurred to generate revenue. This is where most startups go wrong—having either too few accounts (everything lumps into 'Expenses') or too many (accounts for every vendor).

At pre-seed, you don't need elaborate structure. Focus on the basics:

Assets: Cash, Accounts Receivable, Prepaid Expenses

Liabilities: Accounts Payable, Credit Cards, Deferred Revenue

Equity: Common Stock, Additional Paid-in Capital, Accumulated Deficit

Revenue: Product Revenue, Service Revenue

Expenses: Salaries, Contractors, Software, Marketing, Legal, Office, Other

That's about 20 accounts total. The goal is consistency and simplicity, not detailed analysis.

As you raise seed funding and hire employees, add sub-accounts for the major expense categories:

Split Salaries into Payroll and Benefits

Add sub-accounts for major software tools (Salesforce, AWS, etc.)

Break Marketing into Advertising, Events, Content

Start tracking Cost of Goods Sold if you have direct costs

Add a proper Fixed Assets account with accumulated depreciation

This gives you visibility into where money is going without overcomplicating things.

At Series A, you likely have multiple departments, more complex operations, and investor reporting requirements:

Add departmental breakdown (Engineering, Sales, Marketing, G&A)

Implement proper fixed asset tracking with depreciation schedules

Add multi-entity accounts if you have subsidiaries

Break out contractor expenses separately from employees

Add detailed revenue sub-accounts by product line or customer segment

Consider cost center tracking for departmental P&L

After setting up hundreds of startup charts of accounts, we see the same mistakes over and over:

Too few accounts: Everything goes into 'Revenue' or 'Expenses' with no breakdown. You can't analyze anything.

Too many accounts: Creating an account for every vendor makes reporting a nightmare.

Inconsistent naming: Using 'Marketing,' 'Advertising,' and 'Ads' interchangeably creates confusion.

Missing key accounts: Not having deferred revenue, accrued expenses, or prepaid expenses means you can't do accrual accounting properly.

No naming convention: Accounts should follow a logical numbering system that groups related accounts together.

Follow these principles as you build and maintain your chart of accounts:

Start with a template designed for startups—don't use the default from your accounting software.

Document your account structure in a reference document that everyone uses.

Train anyone who enters transactions on the correct accounts to use.

Review your chart annually and add accounts as needed for new business lines.

Keep the number of accounts proportional to your stage—don't over-engineer early.
