The short version
- Only OpenBOM has a free tier, so it costs nothing to try first.
- Each has a real cost: 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.; Sage X3 sage sells X3 through partners rather than direct, so implementation quality varies more than the software does, and a weak partner produces a failed project on a product that works fine elsewhere.
- They diverge on capability: OpenBOM covers Multi-level BOMs, Sage X3 covers Multi-company and multi-legislation finance.

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.
Sage X3
- Sage sells X3 through partners rather than direct, so implementation quality varies more than the software does, and a weak partner produces a failed project on a product that works fine elsewhere.
- Payroll is not part of X3 in most markets and is bought as a separate product or a third party service, so an organisation assuming a complete back office in one licence finds an extra vendor, an extra integration and an extra bill.
- The product uses its own development language and toolset rather than a mainstream stack, so the pool of people who can maintain a customised installation is small, expensive and largely employed by partners.
- Heavy customisation is possible and consequently common, and customised installations are harder to upgrade, which surfaces years later as a business running an old version because taking the current one means retesting and reworking every modification.
- The North American partner ecosystem and third party add-on market are thinner than for the products X3 competes with, so niche requirements are more often met by custom development than by buying something already built.

Answered from the vendors’ own pages
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.
Sage X3: Is Sage X3 a cloud product?
It is offered as a hosted subscription, commonly on AWS, but it is not a multi-tenant SaaS product in the way Plex or NetSuite are. You still have your own instance and you still own the upgrade decision, which is both more control and more work.
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.
Sage X3: How do I choose a partner?
Ask for two references at your revenue, in your industry, on the version you are buying, and speak to them without the partner present. Ask who specifically will be on your project, how long they have worked on X3, and what happens if they leave mid engagement.
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.
Sage X3: Does the licence cost tell me what the project costs?
No. For mid-market ERP the services bill commonly matches or exceeds the first year of software, and the subscription clock usually starts before go live, so the first year of licence buys considerably less usable time than it appears to.
OpenBOM: Can OpenBOM replace a full PLM?
For a startup, usually yes. For regulated manufacturing needing controlled workflows and full audit trails, no.
Sage X3: Who should not buy X3?
A single entity operating in one country, because the multi-company and multi-legislation depth is the main reason to pay for this rather than something simpler, and a business paying for it without using it has overbought.
