.. _Listing customers: Listing customers ================= In Tryton, by definition, the `Parties <party:model-party.party>` that have bought `Products <product:concept-product>` from your `Company <company:model-company.company>` are its customers. The *Sale Module* lets you get a list of these from the [:menuselection:`Parties --> Parties --> Associated to Sales`] main menu item. .. tip:: For some companies it is important to know which parties are, or may eventually be, customers before they have bought anything. One way you can do this is to create a ``Customer`` `Category <party:model-party.category>`, and add all the appropriate parties to it. .. _Making products salable: Making products salable ======================= Before you can add a `Product <product:concept-product>` to a `Sale <model-sale.sale>` it must be marked as salable. When you do this you will also be able to set some additional properties such as the `Unit of Measure <product:model-product.uom>` the product is normally sold in and how long it normally takes before the product can be delivered. .. _Finding sale prices and availability: Finding sale prices and availability ==================================== Before making a `Sale <model-sale.sale>` it is sometimes useful to know how much of a `Product <product:concept-product>` is available, and what the sale price will be. You can get a list of this information for the salable products by using the [:menuselection:`Sales --> Salable Products`] main menu item. The `Sale Context <model-product.sale.context>` allows you to adjust the various parameters that can effect stock availability and price, such as which `Warehouse <stock:concept-stock.location.warehouse>` will be supplying the product, who the customer is and how much they want to buy. .. tip:: As with all Tryton data you can export this list to a :abbr:`CSV (Comma Separated Value)` file by using the form's :guilabel:`Export` menu item.
