You can’t just use Memberstack to achieve this. Two sided Marketplaces has been done on Webflow, e.g. Unicorn Factory made by Connor Finlayson. There is a video where he talks about briefly on how to get started, using a combination of Webflow, Memberstack, Airtable & Zapier.
This should be a self-hosted project. I would recommend Coffee Cup’s site designer, Pinegrow or Wappler. These are desktop applications designed for advanced designers building multi-level processes for a front end user. The back end is where you will build all of those variables. A hosted software won’t accomplish this. Check these three out, you’ll see what I mean after reviewing the feature list. You’ll need a number of databases to manage user levels, etc. Wappler will be the most flexible because you can build and connect directly inside the app.
@imtiazraqib just wanted to clarify that Memberstack focuses on enabling Webflow developers seamlessly add memberships, auth, and payments to their Webflow sites, but we currently do not support allowing those members to sell to one another as @Asher_Fishman needs. For this use case we would also suggest trying out @Tangram.co.
