Kase provides 3PL fulfillment for ecommerce brands.
Kase (formerly ShippingTree) is an omnichannel 3pl that picks, packs, and ships Shopify orders from a multi-warehouse network with pre-negotiated carrier rates. Best fit for brands shipping enough volume that in-house fulfillment is eating ops hours, or whose single-warehouse setup is paying for too many cross-country zones.
What Kase does for Shopify brands
- Multi-node warehouse footprint cuts shipping zones per order
- Pre-negotiated carrier volume rates beat what single-warehouse brands get solo
- Outsourced pick, pack & ship absorbs in-house ops hours on labels & inventory
- 95%+ order accuracy cuts wrong-item returns that cost margin twice
- 22-hour dock-to-stock keeps new inventory sellable fast
