String

String is a small engineering firm that builds, deploys and maintains the shipping logic brands and 3PLs run inside ShipStation. It exists for the point where an operation's fulfillment rules become specific to that business, and ShipStation's automation rules can no longer express them.

The work covers the decisions a person would otherwise make by hand on every order: which box a mixed order goes in, whether a carrier's flat-rate box beats standard rates for that order, how to split an order that won't fit one box, how to batch by zone, cutoff, service level and pick path at once, which warehouse ships it, when to hold an order for inventory, and how packaging should change with the destination forecast.

String is a third-party integration built on the ShipStation API. It reads each order, makes the decision, and writes the result back to the same order before anyone on the floor sees it. Orders are never rerouted, labels are bought in ShipStation on your own carrier accounts, and there is no separate dashboard or seat to license. If String is switched off, your ShipStation account is exactly as it was.

Pricing is flat and monthly, starting at $500, with no per-shipment fee, no percentage of savings, and nothing tied to order volume. String builds your logic first; you then run it free for 30 days on your real orders, and the 30 days don't start until it's working the way you described.

String is a product of DataConstruct Inc., based in Winnipeg, Manitoba, and works with operations across North America. String is independent of ShipStation and Auctane.
