Inventory accuracy first, then labels
Shipping tools shine at rates, labels, and carrier rules. Inventory tools shine at knowing what is actually on the shelf before you promise a ship date. StockFlow is built for the second job: barcode receiving, picks, packs, and multi-location availability. Rates and labels stay in your carrier account or shipping tool.
This page replaces thin per-carrier pages with one fulfillment guide.
Carriers: FedEx, UPS, USPS, DHL
Confirm picks against StockFlow stock, then create labels in the carrier portal or your existing multi-carrier tool. Negotiated rates, customs docs, and tracking stay where your contracts already live.
ShipStation, Shippo, and batch fulfillment
ShipStation and Shippo are common for batch labels and address validation across carriers. You can keep using them while StockFlow owns inventory truth: get orders into ShipStation/Shippo from your storefront as you do today, and use StockFlow so warehouse staff are not picking SKUs that are already sold out.
- Pick against StockFlow on-hand
- Print labels in ShipStation, Shippo, or carrier tools
- Reconcile exceptions (short picks, damages) back in StockFlow
Recommended warehouse flow today
Receive with barcode scanning into StockFlow locations. Release picks only for available stock. Pack and hand off to your label tool.
