A marketplace on Reign has two audiences on one login. Sellers need a dashboard to list what they sell, see orders and get paid. Buyers need to browse, check a seller and buy without friction. The community layer serves both: a seller profile with a feed and reviews gives a buyer a reason to trust someone they have never met, and a space for sellers gives your vendors a place to ask how payouts work instead of opening a support ticket each time.
For services and custom work, WP Sell Services covers the core: service listings, seller profiles, orders with Stripe and PayPal checkout, milestones for larger jobs, and commissions. A buyer orders, the seller delivers against milestones, and the commission is taken when the order completes. For physical products, Dokan, WC Vendors and WCFM all run on WooCommerce, and Reign styles each through its own add-on, so the shop, vendor stores and checkout match the rest of the site.
The work that decides whether a marketplace grows is curation. Approve sellers before their first listing goes live, write a short guide on what a good listing looks like, and pin it in the sellers space. Watch the moderation queue for reported listings and reviews. A smaller marketplace with trusted sellers grows faster than a large one buyers learn to be careful in.
Start with the guide that matches what your sellers sell: services and custom work, or one of the product guides above. Then look at a live store on the demos page and check the add-on you need on the pricing page.
