ShipEdge

The Shipedge fulfillment integration runs in both directions. Orders transmit out to Shipedge for picking and shipping, tracking comes back on each shipment, and inventory levels sync from Shipedge into your UltraCart items, so what the storefront advertises matches what is actually on the shelf.

Shipedge is an omnichannel platform built from three parts: an order management system, a warehouse management system, and an embedded shipping engine. It carries more than 75 channel integrations and 50 shipping carriers, alongside an open API and a rules engine for workflows that do not fit a template. Its customers range from single-warehouse ecommerce brands to third-party logistics providers and large enterprises, including Nestlé's Bountiful Company brands, which run legacy A-Frame and pick-to-light equipment on Shipedge's cloud WMS.

Overselling is what happens when your storefront and your warehouse disagree about stock. The usual remedy is a nightly export that is already wrong by breakfast. Shipedge closes that loop instead, pushing counts into the matching UltraCart items as they change on the warehouse floor. Orders travel the opposite way across the same connection, where each one gets picked, packed, cartonized, and rate-shopped against Shipedge's carrier list before a label prints.

Connecting it means pasting four values from your Shipedge OMS preferences screen: an API key, an account ID, the warehouse you fulfill from, and a store ID that Shipedge suggests generating by creating an API integration under Channel Automation. Naming the warehouse explicitly is what lets one UltraCart account address several Shipedge facilities as separate distribution centers. When something goes wrong, UltraCart keeps a full transmission log under Operations, Reporting, Logs, where you filter to distribution center traffic and open the raw request and response JSON for any single order rather than guessing at what Shipedge received.
