Invoice

An invoice or bill is a commercial document issued by a seller to the buyer, indicating the products, quantities, and agreed prices for products or services the seller has provided the buyer. An invoice indicates the buyer must pay the seller, according to the payment terms. The buyer has a maximum amount of days to pay these goods and are sometimes offered a discount if paid before. From the point of view of a seller, an invoice is a sales invoice. From the point of view of a buyer, an invoice is a purchase invoice

An invoice is essentially a detailed bill left by vendors and outside suppliers for goods or services rendered to a company. A typical invoice might list the quantity of each item, prices, billable hours, service description and a contact address for payment. While some expenses may be paid out of a general fund or petty cash account an invoice is usually paid through an accounts payable department by the posted due date.

An invoice is a legal document which can be used as evidence of an incurred debt. The recipient of the goods or services can challenge the legitimacy of individual charges, but the invoice itself is considered a bona fide debt. Sometimes a vendor or serviceman cannot collect on a bill immediately, so their company will send an invoice at a later date for payment. The actual daily expense of a service may be so low that a company will simply wait for a larger invoice to cover all of the costs at once. Vending machine attendants and bottled water providers may only send one invoice a month instead of billing the company a few dollars a day for supplies.
