Where each one falls short

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

Propel

  • Your product data lives in a Salesforce org, so a future decision to leave Salesforce becomes a PLM migration as well as a CRM one, and the extraction is not trivial.
  • CAD data management is handled through connectors rather than natively; Propel manages metadata and files well but is not a substitute for a CAD vault on large assemblies.
  • The published cost bands are extremely wide, from 10,000 to 500,000 US dollars a year, and setup can approach the annual licence, so early budgeting without a scoped quote is close to meaningless.
  • Licence roles are split across Performance, Quality, Enrichment, Collaboration and Partner types, and buyers frequently discover mid-project that a user needs a more expensive role than budgeted.
  • Salesforce platform limits such as governor limits, API call ceilings and storage allowances apply, and organisations with very large BOMs or heavy integration traffic hit them in ways a purpose-built PLM would not surface.

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
