Quote vs Invoice – Difference Explained | ComTools

Quote vs invoice: a quotation is an offer before work; an invoice is a payment request after delivery. Learn when to use each and how to convert a quote to invoice.

Definitions

Quotation (quote): proposed prices and scope, often with validity date—not a tax document until accepted. Invoice: bill for goods/services rendered, triggers payment and accounting entry.

Workflow

Send quotation → client accepts → contract/PO → deliver work → issue invoice. ComTools helps at the quotation stage; export Excel/PDF as attachment to email.

FAQ

Can a quote become an invoice? Yes—reuse line items and totals but change document title, add invoice number and payment due date.
