Accounts receivable invoices are documents that communicate the details of a transaction to a customer. They list the items purchased, along with any discounts or other applicable charges. They also include information about payment deadlines and the total amount due. In essence, an accounts receivable invoice is the business equivalent of a receipt—a written claim of what you owe. Although they may seem like straightforward documents, accounts receivable invoices play an important role in every successful business. They provide customers with reliable documentation of their purchase and empower them to keep track of their accounts payable.
