Hi,

You can categorize your products by brand in Odoo to generate sales reports using two primary methods. For all Odoo editions, the recommended approach is to utilize Product Attributes: you create a new attribute named "Brand," add your specific brand names as values, and then assign these brands to your products. This allows you to filter and group sales data by brand in your sales analysis reports. If you are an Odoo Enterprise user, you can also leverage Odoo Studio to add a custom "Brand" field directly to your product forms, either as a Many2One field linking to a separate brand model or a selection field, providing a dedicated and integrated way to manage and report on product brands.
