What’s an Invoice?

An invoice is a legally binding document issued by a seller to a buyer after delivering goods or services. It formally requests payment while detailing the transaction: itemized costs, quantities, taxes, and the total due. Key elements include unique invoice numbers, payment terms (e.g., Net 30), and due dates. Invoices enable professional billing, serve as proof of sale for taxes, and streamline cash flow management. They protect both parties, ensure accurate bookkeeping, and accelerate payments. Essential for freelancers, small businesses, and corporations alike.
