What quote tracking does
In most small businesses a quotation is a document. Someone opens last month's file, edits the numbers, saves a new copy, emails it, and moves on. From that moment the quote exists only in the customer's inbox and in the memory of the person who sent it. If they are busy, on leave, or gone, the proposal is effectively lost.
Quote tracking makes the quotation a record instead of a file. It has a value, an owner, a status, a validity date, a revision history and a next action. That is what lets you answer questions no spreadsheet can: how much is sitting in open quotations, which proposals have not been touched in ten days, which customers are negotiating, and which quotes expire this week.
