Chart of Accounts is basically a place where you can see all your accounting headers. Open helps you getting your basic chart of accounts set up by default.
Assets are things of value that your business owns. An asset can be something tangible like cash, bank accounts, property, or a piece of equipment. Or it can be something intangible, like intellectual property or goodwill. Examples of common asset accounts include bank accounts like checking or savings accounts, inventory, buildings or equipment, and accounts receivable, which is money your business is owed by customers for products or services you've provided.
Income is the revenue that your business earns. This can be operating revenue from the goods or services that your business sells or passive revenue from things like investments.
Expenses are outflows of funds from your business to pay for goods and services that your business uses.
Just like with income accounts, use expense accounts to track your different business costs and gain deeper insight into your business.
Liabilities are funds your business owes to other parties—in other words, debt. Credit card balances, business loans or lines of credit, and outstanding bills or sales tax due to the government are all examples of common business liabilities.
Equity represents the difference between your assets and liabilities and measures the net worth of your business. In other words, equity is what would be left over if you sold all your business assets and paid all your debt.
You add equity to your business when you or someone else invests money in the business. You draw equity from your business by taking money from it for personal use.
