You can use a third-party app, called Multi Vendor Marketplace, which can allow vendors to list products on your store. Vendors can have their own profile and collection page, and you can use this app to set up individual or global commissions for your sellers. However, I'm not sure if the vendors can manage their own product as it seems the products need to be uploaded by CSV. That being said, if you need to get help with a third-party app, then the app developer is always available to assist you. Simply reach out to them directly using the contact information found at the bottom of their app's page.
I noticed that you're a new member of our Shopify Community! Once you've had a chance to look over Multi Vendor Marketplace, I'd love to hear more about your experience so far and share some resources to help you get started.
