The short version

  • Each has a real cost: Odoo the free plan is limited to one app, so any second module moves the whole account to a paid per user plan; 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.
  • They diverge on capability: Odoo covers Sales management, OpenBOM covers Multi-level BOMs.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Odoo

  • The free plan is limited to one app, so any second module moves the whole account to a paid per user plan
  • Standard runs $13.50 to $16.90 per user per month and Custom $20.40 to $25.50, both quoted with a yearly discount applied
  • Implementation services and custom development are not included in any plan
  • Odoo.sh hosting is required for custom modules and is charged separately from the subscription
  • SMS credits and AI scanning are billed on top of the per user price

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.
