West Virginia Invoice is a document that is used by West Virginia businesses to bill their customers for goods or services rendered. It typically contains information such as the customer’s name, address, contact information, itemized list of goods or services, cost of each item, total cost, terms of payment, and the due date. There are two main types of West Virginia Invoice: a sales invoice and a service invoice. A sales invoice is used when a business sells goods, while a service invoice is used when a business provides a service. Both types of West Virginia Invoice must include the same information, but may include additional information such as a discount, taxes, and shipping charges.
