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.; SAP S/4HANA implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • They diverge on capability: Plex Manufacturing Cloud covers Built-in MES, SAP S/4HANA covers HANA in-memory database.
  • 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.

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.

SAP S/4HANA

  • Implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • Custom ABAP from an ECC installation must be assessed against the simplification list and either retired or rebuilt, and this remediation is normally the largest and most underestimated line in a brownfield conversion.
  • The public cloud edition constrains modification by design, so organisations that depend on non-standard processes are pushed either to change the process or to pay for the private edition, and that decision is often made after the contract is signed.
  • SAP intends extensions to live on the separately licensed Business Technology Platform, so the extensibility model that makes upgrades safe also adds a second subscription and a second set of skills to the total cost.
  • Exit is effectively impossible at reasonable cost, because the data model, the accumulated configuration and the trained staff around a large installation represent a switching cost that outweighs any competing vendor's discount, so the decision binds for a decade or more.

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.

SAP S/4HANA: What is the actual deadline for leaving ECC?

SAP has set mainstream maintenance for the older Business Suite to end in 2027, with paid extended maintenance available for a further period to 2030. Confirm the current dates and terms with SAP directly, because the commercial detail has been adjusted more than once and it determines your negotiating window.

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.

SAP S/4HANA: Greenfield or brownfield?

Brownfield carries your existing configuration and custom code forward, which is faster to start and slower to finish because everything must be remediated. Greenfield rebuilds on standard processes, which costs more in change management and leaves a cleaner system. The right answer depends mostly on how much of your existing configuration you would defend to a board.

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.

SAP S/4HANA: Is the public cloud edition cheaper?

To run, generally yes. Whether it is cheaper overall depends on whether your processes fit within its extensibility limits. If they do not, the savings evaporate into workarounds or into a move to the private edition.

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.

SAP S/4HANA: How should I approach pricing negotiation?

Treat licence, infrastructure, BTP, the integrator and the internal backfill as one number and negotiate against it. Also settle indirect and digital access terms explicitly in writing, since usage from connected systems has been a recurring source of unbudgeted cost.
