WCFM Membership stores tier definitions as wcfm_membership custom posts and per-vendor subscriptions in wcfm_memberships linked to the vendor user. The default admin lists tiers in one screen and active subscriptions in another, with per-vendor renewal status only visible by opening the individual subscription record.

SleekView joins memberships with vendor users so a single row shows store name, plan, renewal date, payment status, and the limits configured on that tier (max products, commission rate, custom commission rules). Filter for vendors approaching their renewal window, sort by tier upgrade revenue, or scope to free-tier vendors with above-average performance who are candidates for an upgrade conversation.

Renewal records, status transitions, and tier overrides are first-class fields, so a saved view called 'Premium expiring this month' becomes a recurring growth task instead of a one-off SQL query. Inline tier changes write through WCFM Membership's API so the vendor's commission rules and limits update at the same time their plan does.

Tiered membership is how a marketplace turns its data into revenue beyond commission. A vendor on a Premium plan pays a recurring fee and gets higher product limits, a lower commission rate, and feature access. The marketplace's job is to keep Premium vendors growing into their plan and free vendors aware they could grow into Premium.

Both are operational workflows that need vendor-level data, tier-level data, and time-window-level data in the same view. WCFM Membership stores all of that data correctly. The default admin shows tiers as a list and active memberships as another list and renewal records as a third list, which means growth ops, finance, and vendor support each have to assemble their own picture from separate screens or run custom SQL.

SleekView gives each of those teams a saved view scoped to their workflow, all reading the same underlying tables and writing through the same APIs. The growth pipeline becomes a one-click view of upgrade candidates. The renewal pipeline becomes a one-click view of vendors due in the next 30 days.

The vendor support lookup becomes one row instead of three tabs. That changes membership management from a periodic export-and-spreadsheet task into a continuous operational practice.
