What is the difference between a sales invoice, a tax invoice, & a service & sales invoice?

When should you use a service and sales invoice?
And when would you use a tax invoice? (being a business).

Are there any other types of invoices? And when do you use them.

An invoice or bill is a commercial document issued by a seller to a buyer, indicating the products, quantities and agreed prices for products or services with which the seller has already provided the buyer. An invoice indicates that payment is due from the buyer to the seller, according to the payment terms.

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. The document indicates the buyer and seller, but the term invoice indicates money is owed or owing. In English, the context of the term invoice is usually used to clarify its meaning, such as "We sent them an invoice" (they owe us money) or "We received an invoice from them" (we owe them money).
