Where each one falls short

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

DEAR Systems

  • DEAR Systems is sold as Cin7 Core and priced on the Cin7 pricing page
  • The $349 per month Standard plan caps sales orders at 6,000 per year, includes 5 users and 2 e-commerce integrations
  • Material requirements planning requires the Pro plan at $599 per month
  • Advanced warehouse management requires the Advanced plan at $1,199 per month
  • Additional users, extra integrations, API access, forecasting and advanced automations all cost extra and are priced by the sales team
  • The Omni enterprise plan is custom priced with no published rate

OpenBOM

  • Pricing has three axes, editing seats plus data record count plus per-seat CAD add-ins at $25 to $45 each, so the real annual cost is well above the advertised per-seat figure.
  • Paying yearly nearly halves the seat price, from $55 to $30 and $165 to $90, so monthly billing carries an unusually heavy penalty for teams that want flexibility.
  • Change management, revision control and CAD file management are absent from the entry Team plan, so the cheapest tier is a catalogue rather than a working PLM.
  • It lacks the approval workflows, effectivity dating and audit depth that regulated medical and aerospace suppliers need, so companies pursuing ISO 13485 or AS9100 typically migrate away.
  • Record count is metered separately and a large imported part library can push a small team into a higher data tier without adding a single user.
