The per-client fee punishes the wrong thing.
Every SMB 3PL is trying to land more clients — and Extensiv charges you $50/mo for the privilege of each one. Land a $1,200/mo retainer, lose $50 to software, your effective margin drops before you ship a box. Operators tell us they delayed onboarding clients waiting for the next billing cycle. Flat pricing flips that — your 11th client costs zero in additional software.
