An invoice, or a bill, is a commercial document sent from a seller to a buyer as a request for payment, indicating what was sold and how much is owed.
Invoices, like bills, are issued from a vendor to a customer for something they’ve already received, something in development, or something that’s ready to be created. But invoices, unlike a restaurant bill, aren’t necessarily due immediately upon receiving them. You may choose to set invoice payment terms of up to 3 months, to give your customers flexibility to manage their cash. Get a more in-depth invoice definition with examples in our guide.
