The product Vendor field (on Shopify) and Manufacturer field (on Lemonstand) are another way to tag your products based on the brand of the product.
For example, if you sold shoes, you’d put Nike or Reebok in that field.
You can also display the Vendor/Manufacturer on your product pages if you include the field in your template.
It’s a tie. Both Shopify and Lemonstand have a dedicated field for this because it’s a common piece of information to want to include about your products.
