ShipStation is powerful. String makes it effortless. The right box, the right rate, the right workflow, every time.
Pick the right box every time so you don't waste space or money
String picks the cheapest carrier that still gets the package to your customer when they expect it without the extra clicks.
Out of stock? String holds the order and ships it as soon as it's ready.
If only part of the order is ready, String ships what's available and holds the rest.
Ship in-stock items now and send pre-orders later — automatically.
String automatically splits big orders into separate ones for each box.
Group similar orders together so you ship more in fewer steps.
No need to change tools — String runs right inside ShipStation.
The smart layer for ShipStation: fewer clicks, fewer errors, more savings.
