An invoice is a document or electronic statement stating the items sold and the amount payable. It is also called a bill. Invoicing is when invoices are produced and sent to customers. It is used to communicate to a buyer the specific items, price, and quantities they have delivered and now must be paid for by the buyer. Payment terms will usually accompany the billing information.
It's a good idea to hang onto your invoices for at least a year, especially if they relate to significant purchases. Better safe than sorry!
If you spot a mistake, don’t hesitate! Contact the company right away to clear things up. They’ll likely want to make it right as quick as a flash.
If your invoice seems to have gone MIA, don’t sweat it! Check your spam folder and if it's not there, reach out to the company you purchased from to get a copy.
