How WarpWare EDD works

Real-time calculation from your actual operational data. Not static rules — live warehouse, inventory, and carrier intelligence.

Inventory Location

WarpWare knows which warehouse has each SKU in stock — pulled live from your WMS, not a default assumption.

Warehouse Processing

Per-warehouse SLAs, cutoff times, operating days, and holiday calendars. WarpWare handles the timezone math.

Carrier Transit Times

Over 1M zip-to-zip records for USPS, UPS, and FedEx across every service level. Updated from carrier zone charts.

SKU-Level Overrides

Custom or made-to-order items take longer. Per-SKU processing overrides automatically adjust the estimate.

Processing+Transit=Delivery Date

Adjusted for cutoff times, weekends, holidays, and SKU-level overrides

Multiple options, one API call

Return Ground, Express, 2-Day, and Overnight estimates in a single request. Let your customers choose based on urgency and budget.
