1. Unified Order Queue with Priority Sorting

Orders from all 4 platforms are aggregated into a unified queue sorted by: order age (older orders first), shipping deadline (expedited shipping urgency), and platform (configurable priority). This ensures the seller always processes the most critical orders first regardless of which marketplace they came from.

2. One-Click Fulfillment Chain

A single click on "Fulfill Order" triggers the complete fulfillment chain: (1) generate shipping label via ShipStation API, (2) push tracking number back to originating marketplace, (3) decrement inventory across all channels, (4) generate packing slip PDF. This 4-step process completes in under 10 seconds vs. 3-5 minutes of manual platform-switching.

3. Cross-Channel Inventory Ledger

When a product sells on any channel, the inventory count decrements immediately on all connected channels — preventing overselling. The central inventory ledger in chrome.storage.sync acts as the source of truth, with changes pushed to each platform API in parallel. Conflict resolution handles simultaneous sales across platforms.

4. Cross-Platform Schema Normalization & Error Logging

Data formats vary widely between external platforms. The engine maps diverse schema variations into standardized strongly-typed data contracts, validating field formats before dispatch and streaming diagnostic event logs for rapid issue resolution.
