New Requests lists what customers want in your categories: where to deliver, how they would like to pay, and when quotes close. Prices come from your items, so listing products first saves typing.

Quotations follows the quotes you have sent.

An accepted quote becomes an order under Orders. Ship it, follow what the customer confirms has arrived and what is still to be paid, and talk to them under Chats. Invoices and Payouts hold the money side.
