The short version

  • Only OpenBOM has a free tier, so it costs nothing to try first.
  • Each has a real cost: Acumatica pricing is not published; the vendor directs buyers to a pricing review or an industry calculator instead; 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: Acumatica covers Financial 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.

Acumatica

  • Pricing is not published; the vendor directs buyers to a pricing review or an industry calculator instead
  • Cost is driven by transaction volume, data storage and resource levels, so spend rises with business activity rather than staying fixed
  • Charged per application implemented, so adding a module changes the 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.

Answered from the vendors’ own pages

Acumatica: How does Acumatica's pricing model work compared to traditional per-seat ERP systems?

Acumatica charges based primarily on the number of applications you implement, not user seats. Pricing adjusts based on business usage and resources (transaction volumes, user count, data storage needs) plus your chosen deployment license type. Unlimited users are included; you only pay for the functionality you need.

OpenBOM: Is OpenBOM free?

There is a genuine free tier limited to 2,000 data records and aimed at non-commercial and educational use. Commercial teams start at $30 per seat per month billed yearly.

Acumatica: Are there separate pricing calculators for different industries?

Yes, Acumatica offers industry-specific pricing calculators for Construction, Manufacturing, and Distribution to help estimate costs. You can also schedule a custom pricing review with an Acumatica partner for a tailored assessment.

Source
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.

Acumatica: What happens if my business usage and data storage needs grow over time?

Acumatica allows you to adjust resource levels and data storage as you add users or expand usage. The transparent pricing model ensures you always know your costs, and you do not pay overages for unused features or unnecessary functionality.

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.
