McCall's ambition is no less than to "become the Salesforce.com of the transportation management industry," he said.

ShipIt is targeted at U.S. companies that spend more than $100,000 a year on shipping. Those include Internet retailers and many law firms.

But ShipIt can make sense for even due to Enroute's friendly startup cost (It charges 10 cents to a dollar per package, and claims it can shave $1 to $3 off the average $12 per-parcel shipping fee).

That, claimed McCall, is far cheaper than incumbent client apps offered by companies such as Kewill or Pitney Bowes.

Enroute, which is based in Bellevue, Wash., already claims a number of customers, including Seattle-area e-commerce retailers such as Cutter&Buck and Zumiez.
