Where each one falls short

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

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.

Unleashed

  • Limited reporting customization for specific business metrics
  • Cannot edit invoices once they are complete
  • Mobile app has limited functionality compared to desktop version
  • Advanced features like demand forecasting and bin-level stock tracking are missing or require higher-tier packages

Answered from the vendors’ own pages

OpenBOM: Do I pay for people who only look at BOMs?

No. Read-only users are unlimited and free on every paid plan, which is the main reason the total cost undercuts seat-for-seat PLM tools.

Unleashed: What accounting software does Unleashed integrate with?

Unleashed integrates seamlessly with Xero and QuickBooks, as well as various e-commerce and point-of-sale systems. However, integration with some platforms like Magento 2 has been reported as problematic.

Source
OpenBOM: Are the CAD add-ins included?

No. They are $25 per seat per month billed yearly, $45 monthly, and require an active Team or Company subscription.

OpenBOM: Can OpenBOM replace a full PLM?

For a startup, usually yes. For regulated manufacturing needing controlled workflows and full audit trails, no.
