From a quoted price to a recognised one.

A quotation is priced from the customer's list with the applicable rules applied, checked against stock availability, and given a validity date rather than an open end.

The accepted quotation becomes an order carrying rates, taxes, delivery schedule, and payment terms — tested against the credit limit before it commits.

Picked, reserved, packed, and shipped in as many movements as the order needs, with the order tracking what remains rather than closing early.

Invoiced from order or delivery, revenue deferred where it should be, and margin read against the valuation the stock ledger actually holds.
