The short version

  • Only Dolibarr has a free tier, so it costs nothing to try first.
  • Each has a real cost: Dolibarr the core is deliberately shallow, so a serious requirement such as advanced manufacturing, EDI or a specific payment gateway usually means buying a DoliStore module from a third-party author, and the quality and maintenance of those modules varies widely.; Plex Manufacturing Cloud there is no on premise option, so a plant whose line-side terminals must keep working through a network outage needs a mitigation plan, and connectivity becomes a production dependency rather than an IT concern.
  • They diverge on capability: Dolibarr covers Module toggles, Plex Manufacturing Cloud covers Built-in MES.
  • 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.

Dolibarr

  • The core is deliberately shallow, so a serious requirement such as advanced manufacturing, EDI or a specific payment gateway usually means buying a DoliStore module from a third-party author, and the quality and maintenance of those modules varies widely.
  • Accounting was designed around French practice, and the chart of accounts, VAT model and fiscal exports need real work to satisfy accountants in the United States, the UK or Australia.
  • The interface is functional rather than designed and shows its age against Odoo, which makes internal adoption harder when staff are comparing it to consumer-grade software.
  • Upgrades between major versions can break paid third-party modules, because module authors update on their own schedules and there is no guarantee your combination will work on version 24 the day it ships.
  • Support is community forums unless you buy a partner contract, and the documentation is a wiki of uneven quality with substantial parts written in French, so English-only teams hit dead ends.

Plex Manufacturing Cloud

  • There is no on premise option, so a plant whose line-side terminals must keep working through a network outage needs a mitigation plan, and connectivity becomes a production dependency rather than an IT concern.
  • Every customer runs the same version on the vendor's schedule, so you cannot defer a release to fit around a plant shutdown or a customer audit and must absorb regression testing on the vendor's cadence.
  • Customisation is limited to the platform's own configuration and extension tools, which is what makes the single version model possible but means a process you cannot express within those tools has to change rather than be accommodated.
  • The financial modules are less developed than the operational ones, so groups with complex multi-entity consolidation, statutory reporting in several countries or sophisticated planning requirements often keep a separate finance system alongside it.
  • Country localisations and language coverage are narrower than the tier one vendors offer, which limits the product for a manufacturer expanding into markets with demanding local tax and reporting rules.

Answered from the vendors’ own pages

Dolibarr: Is Dolibarr genuinely free?

Yes. The full application is GPL with no user limit and no paid edition of the core. You pay only for hosting, optional DoliStore modules and optional partner support.

Plex Manufacturing Cloud: Can I run Plex on my own servers?

No. It is delivered as multi-tenant cloud software only. If you need an on premise deployment, this product cannot meet that requirement at any price.

Dolibarr: Can it run on shared hosting?

Yes, that is its main practical advantage. It needs only PHP and MySQL or MariaDB, so an ordinary cPanel account is enough.

Plex Manufacturing Cloud: What happens to my customisations at upgrade time?

There are no customisations in the traditional sense. Extensions are built with the platform's own tooling and are carried forward by the vendor. That is the trade you are making: less freedom to modify, no upgrade project.

Dolibarr: How does it compare to Odoo?

Odoo is deeper and better presented but its useful modules are in the paid Enterprise edition and it needs a proper deployment. Dolibarr is thinner but free end to end and far easier to host.

Plex Manufacturing Cloud: Has Rockwell's ownership changed the product?

It has placed Plex inside a portfolio with Rockwell's automation, maintenance and analytics products, which pulls the roadmap towards integration with that estate. Whether that helps depends on whether your plant runs Rockwell equipment. Ask about the specific roadmap items you care about.

Dolibarr: Does it handle UK or US accounting?

Not comfortably out of the box. The accounting module reflects French conventions and needs configuration and often a local module to satisfy an accountant elsewhere.

Plex Manufacturing Cloud: Is the finance module enough on its own?

For a single country manufacturer, usually yes. For a group consolidating several entities across countries with statutory reporting obligations, ask specifically about your requirements, because this is the part of the product most likely to fall short.
