How a shipment works, step by step · Which service fits your shipment
Why Mainspring
What you can expect from us
A straight answer
You get a named person who knows your freight, and a clear answer on price, timing and what could go wrong.
The mode that fits, not the one we sell
Because we handle every mode, we can tell you when six pallets should ride LTL and when a truck is cheaper.
No surprises on the invoice
We ask the right questions up front so the extras are in the quote, and we audit the carrier's invoice before it reaches you.
