Activate the Inventory gem from the Holded Store to use rates
In Holded, rates are the names that identify the additional prices. These additional prices can be assigned to a product together with its main rate or price. This way, you can choose the rate of a product depending on your needs.
Some examples of rates are Sales, Mid-season sales, and Premium clients.
From the Price list section in Settings > Inventory, you can create rates. Also, you'll find there all the rates that you have created on the platform with their name and description.
Access here the Price list on the platform
Once the rates are created, you can assign them to the product, determine their amount and check them by clicking on the Price list section of the product panel. You'll also be able to assign default rates to your contacts and your documents to ease your invoicing process.
