Whether you're new to Builtfirst or an existing user, marketplaces can invite you to list discounts as a seller at any time. You'll receive an email titled "[Example Person] requested your deal in [Name's] Marketplace".
Clicking "Accept Invite" at the bottom will have you create a seller account if you haven't already. If you already have a seller account with offers, this button will simply log you in.
Once you've logged into manage.builtfirst.com, you're free to create deals for the marketplace(s) that invited you! ✌️
If you want to offer one of your existing deals to a new marketplace: you must update the Target Audience for your listing before you can change the Deal Segmentation on your discount. More on that here.
