  • Each has a real cost: Katana MRP the free plan caps SKUs at 30 after a 15 day unlimited period; 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: Katana MRP covers Visual production scheduling, OpenBOM covers Multi-level BOMs.

Where each one falls short

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

Katana MRP

  • The free plan caps SKUs at 30 after a 15 day unlimited period
  • The Core plan starts at $299 a month and includes one location, with more sold as a usage based add on
  • Core is billed per sales order delivered on top of the base price, so cost tracks throughput
  • Manufacturing management, traceability and warehouse management are separate add ons at $199, $249 and $149 a month
  • A full manufacturing setup therefore stacks to well above the headline $299

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.
