Very few businesses insist on being paid in cash on the spot every single time, and very few businesses pay every bill the moment it arrives. Instead, businesses routinely buy and sell on credit — the goods or service moves now, and the money follows later. Two accounts exist specifically to track that gap between "now" and "later": accounts receivable and accounts payable.
Accounts Receivable
Accounts receivable refers to the total amount due from debtors, usually within 30 days. A debtor is a customer who owes the business money — the business sold something (goods or a service) but hasn't collected the cash yet. Accounts receivable is an asset: it represents value the business is owed and will likely turn into cash soon, so it sits high up in liquidity order on the balance sheet, right after cash.
Accounts Payable
Accounts payable refers to the total amount owed to creditors for the purchase of goods or services by the business. A creditor is a person or business that has extended credit or loaned money to another individual or business — in other words, whoever the business owes money to. Accounts payable is a liability: the business received something of value but hasn't paid for it yet.
- Money owed TO the business
- Customers (debtors) owe this to us
- Increases when we sell on credit
- Decreases when the customer pays
- Money owed BY the business
- We owe this to suppliers (creditors)
- Increases when we buy on credit
- Decreases when we pay the supplier
Equities: Claims Against the Business
Equities are claims by both creditors and owners against the assets of a company. Liabilities like accounts payable are the creditors' claims — legally, creditors get paid first if a business is wound down. Owner's equity is the owner's claim, and it's what's left over after every creditor's claim is satisfied. That's exactly why the balance sheet equation places liabilities before owner's equity: lists the claims in the order they'd be paid.
