Quotation vs invoice: what is the difference?

Both show money. One says “here is our price.” The other says “please pay.” Mixing them confuses buyers and finance.

The difference

A quotation (quote) is sent before the sale and states the offered price and terms. An invoice is sent after the sale and asks the buyer to pay. Quotely generates quotations only.
