Does Netsuite wms support license plating? What a garbage wms system!
I would proposed to check DSI Globel they have good WMS solution and can create add-ons if you require. NetSuite WMS is for simple flows.
Its capable for what it does, but it has its limitations as does every system! If you want to go all out Waer is the solution for you but your budget should accommodate. Other wise look at RF-Smart or similiar
