The short version

  • Each has a real cost: 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.; Unit4 manufacturing, warehouse management and supply chain planning are not the point of this product, so a business with significant inventory will find capability gaps that no amount of configuration closes.
  • They diverge on capability: SAP S/4HANA covers HANA in-memory database, Unit4 covers Flexible organisational model.
  • 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.

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.

Unit4

  • Manufacturing, warehouse management and supply chain planning are not the point of this product, so a business with significant inventory will find capability gaps that no amount of configuration closes.
  • Payroll is generally handled by a separate product or a regional third party rather than being included, so multi-country organisations end up managing several payroll vendors alongside the ERP.
  • Moving from an established on premise Agresso installation to the current cloud product is closer to a re-implementation than an upgrade, with data migration, process redesign and retraining to pay for on a system that already worked.
  • The consulting and partner ecosystem is considerably smaller than for SAP, Oracle or Microsoft, so specialist skills are harder to hire, cost more, and are concentrated in a small number of firms with limited availability.
  • The flexibility that makes reorganisation cheap also makes it easy to build a model nobody understands, and an organisation that has reconfigured its hierarchy repeatedly without documentation ends up unable to explain its own reporting.

Answered from the vendors’ own pages

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.

Unit4: Is Unit4 ERP the same thing as Agresso?

Yes, in lineage. Agresso is the earlier name for the same product line and long-standing customers still use it. Current marketing uses Unit4 ERP, and the cloud product is a substantially different deployment from the on premise Agresso installations still in service.

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.

Unit4: Can it run a manufacturing business?

Not well. This product is built for organisations whose cost base is people and projects. If your planning problem is materials and production capacity, look at a manufacturing ERP instead.

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.

Unit4: What actually justifies the price against a mainstream ERP?

The cost of change. If your structure is stable, the flexibility is worth little and a mainstream product is cheaper. If you reorganise regularly and each reorganisation currently means a consultancy engagement, that recurring cost is where the business case sits.

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.

Unit4: Is it sold direct or through partners?

Both. Unit4 sells and implements direct in its main markets and also works with partners. Ask which model applies to your region and country, because it determines who is accountable when the implementation slips.
