Where each one falls short

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

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

Tractian

  • Sensors are excluded from both published CMMS tiers and are quoted per monitored asset, so the transparent rate card covers only the part of the deployment that costs least.
  • Smart Trac hardware reports into the Tractian platform, so a plant that later changes analytics vendor writes off the installed sensor base.
  • The five-user minimum on Standard and ten-user minimum on Enterprise put a floor under the cost that small maintenance teams cannot get below.
  • ERP integration, single sign-on and the Power BI connector are Enterprise-only, so an organisation needing SAP integration pays the higher rate for every licensed user including technicians who need none of it.
  • The company is young and venture-funded with rapid product expansion, so enterprise features are newer than the core CMMS and reference sites at large industrial scale are fewer than for established EAM vendors.
