A complete listing of every account in a company's general ledger, organized by category (assets, liabilities, equity, revenue, expenses). Serves as the structural backbone of the accounting system.
Understanding Chart of Accounts
A chart of accounts (COA) is the complete, organized listing of every account used in a company's general ledger. It serves as the structural framework of the entire accounting system, categorizing all financial activity into five main types: assets, liabilities, equity, revenue, and expenses.
Each account in the COA is assigned a unique number and name. A well-designed chart of accounts for an ecommerce business includes specific revenue accounts for each sales channel, detailed expense accounts for marketplace fees, shipping costs, and advertising, and inventory accounts that track product costs.
The chart of accounts should be detailed enough to provide useful reporting breakdowns but not so granular that bookkeeping becomes burdensome. For ecommerce sellers, the right COA structure makes it easy to see profitability by channel, track fee trends, and prepare accurate tax returns.
Why It Matters for Ecommerce
A well-structured chart of accounts is the foundation of meaningful financial reporting for ecommerce businesses. If all marketplace fees are lumped into a single "Fees" expense account, you can't compare Amazon referral fees against eBay final value fees. A thoughtful COA lets you track profitability by sales channel, product line, and fee type.
Practical Example
An ecommerce COA might include: Revenue accounts — "Sales:Amazon," "Sales:Shopify," "Sales:eBay." Expense accounts — "Marketplace Fees:Amazon Referral," "Marketplace Fees:FBA Fulfillment," "Marketplace Fees:Shopify Processing," "Shipping:Outbound," "Shipping:Returns." This granularity lets you see exactly where money goes.
