Marketplaces and Client Portals

Frequently asked questions
What is the difference between a membership site and a multi-vendor marketplace?
A membership site uses gated content and subscription tiers to provide exclusive access to an audience. A multi-vendor marketplace connects independent sellers with buyers so they can manage their own inventory and sales.
Can I use these tools to manage clients for my professional services firm?
Yes. Some options specialize in white-label client portals that combine messaging, billing, and file sharing specifically for agencies and professional services.
Do these platforms handle payments between buyers and sellers automatically?
Several options provide the necessary infrastructure for this. You can use dedicated payment systems to handle seller onboarding and payouts or use e-commerce platforms with built-in marketplace apps.
Which options are best if I want to sell digital products or newsletters?
You should look at creator-focused platforms that offer built-in audience discovery, paid subscriptions, and gated content features. These tools allow you to monetize memberships or sell digital downloads directly to your followers.
