This is a built-in feature of WP Sell Services, not a custom build. The four-tier seller level system ships configured out of the box and progresses automatically based on performance metrics:
- New Seller: default level on signup
- Level 1: 5+ completed orders and 4.0+ average rating
- Level 2: 25+ completed orders and 4.5+ average rating
- Top Rated: 100+ completed orders and 4.8+ average rating
Progression is automatic, it checks on every completed order and rating, so there is no admin nudging required. The level displays on the vendor card, service listings, and the vendor profile page alongside bio, tagline, and social links. Seller Card is one of the six Gutenberg blocks (also Service Grid, Search, Categories, Featured Services, Buyer Requests) so you can drop a level-filtered vendor directory onto any page.
Reputation is reinforced by the multi-criteria review system (communication, quality, delivery) plus vendor reply to reviews, so a Top Rated badge actually correlates with visible feedback quality.
Honest limit: the thresholds are the WP Sell Services defaults. Changing them (say, Level 1 at 10 orders instead of 5) requires using one of the 100+ action and filter hooks the plugin exposes; there is no UI field for custom thresholds today. Pro adds analytics dashboards that show top vendors by revenue, which pairs naturally with the level system when you want to spotlight rising sellers.
