WooCommerce Waitlist (and similar plugins) records an interested shopper against an out-of-stock product or variation. Depending on the plugin, the data lives in a per-user serialised value in wp_usermeta (often woocommerce_waitlist) or in a dedicated table that maps user ID to product ID with a signup timestamp. The default admin tends to show a per-product waitlist with limited filters and no global view of demand or signup order.

SleekView reads the waitlist surface directly and joins to the product and product_variation post types. A merchandiser's daily view ranks products by waitlist length; a fulfilment lead's restock view sorts subscribers by signup date so the first-in-line shoppers get notified first; a support agent's view searches by email to see every product a customer is waiting on. Variation attributes (size, colour, finish) come through the join to product_variation so a row carries the full SKU context.

Inline edits route through the plugin's CRUD layer where exposed: update_user_meta for usermeta-backed plugins, direct table writes with the plugin's wrapper for table-backed ones. Notification dispatch, opt-out logic, and any third-party email-tool sync still fires when status changes inline.

A waitlist is an explicit promise to a customer: you are in line, we will tell you when this SKU comes back. The promise breaks if the plugin's admin makes that line invisible. Most waitlist plugins do the storefront job well, capture the email, write it to usermeta or a table, render a button on the product page, but stop short of giving the merchant a real ranked queue.

Without one, restock notifications go out in whatever order the database returns rows, which is rarely signup order. First-in-line shoppers get treated the same as last-in-line, trust erodes, and the next time the SKU is in demand, fewer people bother joining the list. SleekView models the waitlist as it really is: an ordered queue per SKU, joined to product attributes for fulfilment context, exportable for marketing, scrubbable for GDPR.

Restock notifications go out in signup order, the merchandiser sees true demand ranking, support can answer position questions instantly, and stale entries don't bloat the table forever. Same plugin, same data, materially better customer experience.
