The short version

  • Each has a real cost: SolidWorks the desktop application is Windows only, so Mac and Linux users need a virtual machine, a Windows workstation or the separate cloud xDesign product at 2,580 USD a year.; SOS Inventory the Companion plan at $69.95 per month is limited to a single location and 1 custom field
  • They diverge on capability: SolidWorks covers 3D solid modeling, SOS Inventory covers Lot tracking.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SolidWorks

  • The desktop application is Windows only, so Mac and Linux users need a virtual machine, a Windows workstation or the separate cloud xDesign product at 2,580 USD a year.
  • Perpetual licences are no longer sold through the vendor online store and come only through resellers, and a perpetual licence still needs a paid annual service contract to get upgrades and support, so buying once and paying nothing again is not really on offer.
  • Named-user subscription is per person rather than floating, so an organisation where several engineers each use CAD occasionally pays full seats for part-time use unless it negotiates otherwise.
  • History-based parametric modelling breaks noisily: a change high in the feature tree can cascade rebuild errors through an assembly, which is a real productivity cost compared with direct modelling tools.
  • Large assemblies stress single-threaded desktop performance, and teams routinely resort to configurations, simplified representations and expensive workstations rather than the software scaling on its own.
  • The Maker licence watermarks its files so they can only be opened on other Maker licences, which means hobby work cannot be carried into a commercial seat later without exporting to neutral formats and losing the feature history.

SOS Inventory

  • The Companion plan at $69.95 per month is limited to a single location and 1 custom field
  • Serial and lot number tracking, barcoding and unlimited locations require the Plus plan at $139.95 per month
  • Phone support is excluded from the Companion plan
  • Job costing, advanced manufacturing and the customer portal require the Pro plan at $194.95 per month
  • Each plan includes only 2 to 5 users and additional users cost $25 each per month
  • The 2 months free discount requires paying a year up front
