Sales quotation in Odoo 16 is a feature within the Sales module of the Odoo ERP system. It allows businesses to create and send professional and detailed quotations to their customers. A sales quotation serves as formal document that outlines the products or services being offered, their prices, and any applicable discounts or terms. Sales Quotations are the first step in the process of the generation of sales orders in a business. A sales quotation will document all necessary information related to the sales product in order to give an exact idea to the customer. You can consider a sales quotation and the commercial document between the seller and the customer. It will bring clarification for both parties related to the price of the products included in the sales operation. With the assistance of the Odoo ERP system, you can easily create and send a quotation to a customer which will help the customer to know the exact price details of the products and services offered by your company before signing any sales deals.
