Shippo's WooCommerce extension quotes rates from multiple carriers at checkout, lets the merchant purchase labels from the order screen, and writes the resulting label data back to order meta. Common writeback keys include _shippo_tracking_number, _shippo_carrier, _shippo_servicelevel, and _shippo_label_cost. On HPOS those values live in wc_orders_meta; on legacy stores they live in postmeta.

The default order list shows none of that. Auditing which carrier and service tier each order shipped through, or comparing the rate quoted at checkout against the label cost paid, requires opening every order. SleekView reads those meta keys and renders one row per shipment with carrier, service level, label cost, and tracking. A view sorted by _shippo_label_cost descending exposes the highest-charge shipments for contract review. A view filtered to international service levels feeds the customs paperwork triage.

Inline edits write through WooCommerce CRUD so a manually entered tracking number for an off-platform handover triggers the same order-update hooks Shippo's listeners use. The plugin keeps owning rate quotes and label purchase; SleekView gives the resulting data a WP-native surface.

Shippo is a rate-shopping and label-purchase platform that exposes a unified API across multiple carriers. The WooCommerce extension brings rate quotes into the cart and label generation onto the order screen, then writes carrier, service, and label cost back to order meta. That meta sits in the database where only the per-order screen can see it, which means every operational question, the dispatch sequence, the rate-vs-paid audit, the carrier mix breakdown, requires opening orders one at a time or pivoting to Shippo's dashboard.

SleekView reads the meta Shippo already writes and renders one row per shipment with carrier, service, label cost, and tracking. Ops gets a service-mix table, finance gets a rate-and-service export, support gets a destination-and-status query. Shippo keeps owning the carrier API and the label engine, and WordPress gets the visibility the team that works in it needs.
