The short version

  • Each has a real cost: Omie specific plan pricing not listed; pricing varies based on company size and revenue; 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.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Omie

  • Specific plan pricing not listed; pricing varies based on company size and revenue
  • Pricing model defined as 'conforme o porte e o faturamento da empresa' (based on company size and revenue)
  • Offered in Portuguese only with Portuguese pricing

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

Omie: How much does Omie cost?

Omie ERP pricing is determined based on company size and revenue rather than fixed tiers. Specific plan prices are not listed on the website; contact a consultant for pricing based on your business needs.

Source
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.

Omie: Does Omie offer a free trial?

Yes, Omie offers a 7-day free trial at R$0.00 with no credit card required. The trial includes cloud-based system access, premium customer support, and full access to core features with quick cancellation available anytime.

Source
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.

Omie: What is included in the Omie free trial?

The 7-day free trial includes a 100% online cloud-based system, premium customer support, simple online contracting, and full access to core features without credit card requirements.

Source
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.

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.
