The short version

  • Each has a real cost: 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.; Rootstock every Rootstock user also needs a paid Salesforce platform licence, so the true cost is two subscriptions stacked; third-party estimates put a fully loaded seat around 200 to 500 US dollars per user per month, which is far above the Rootstock line item alone.
  • They diverge on capability: Plex Manufacturing Cloud covers Built-in MES, Rootstock covers Native Salesforce architecture.

Where each one falls short

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

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.

Rootstock

  • Every Rootstock user also needs a paid Salesforce platform licence, so the true cost is two subscriptions stacked; third-party estimates put a fully loaded seat around 200 to 500 US dollars per user per month, which is far above the Rootstock line item alone.
  • Rootstock publishes no pricing whatsoever, so budget-setting depends on reseller and analyst figures rather than vendor rates, and there is no public benchmark to test a quote against.
  • Building on Salesforce means inheriting Salesforce governor limits and API constraints, which surface as batch size and data volume ceilings in high-transaction manufacturing that a purpose-built ERP would not hit.
  • Your ERP is now hostage to another vendors commercial decisions: Salesforce list price rises, edition changes or licence policy shifts flow straight into your ERP running cost with no alternative supplier.
  • Implementation is a serious project, commonly quoted in the tens to hundreds of thousands of dollars and measured in months, and the partner pool that genuinely knows both manufacturing and Salesforce-native ERP is small, which lengthens timelines and raises day rates.

Answered from the vendors’ own pages

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.

Rootstock: Do I need Salesforce to run Rootstock?

Yes, and it is not optional. Rootstock is a managed package on the Salesforce Platform and every user requires a Salesforce licence in addition to the Rootstock subscription.

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.

Rootstock: What does Rootstock actually cost?

Rootstock does not publish rates. Third-party estimates put the ERP subscription at roughly 150 to 300 US dollars per user per month before Salesforce licences, with implementation quoted separately.

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.

Rootstock: Is it suitable for process manufacturing?

It is built for discrete manufacturing. Recipe and batch-driven process manufacturers are a poor fit and should look 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.

Rootstock: Has Rootstock been acquired?

No. Rootstock remains independent and was itself the acquirer, buying Salesforce-native applications firm Ascent Solutions in March 2026.
