The short version

  • Each has a real cost: IFS no price, per user rate, minimum commitment or contract term is published on the site; the only route to a figure is a demo booking; 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: IFS covers Project management, 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.

IFS

  • No price, per user rate, minimum commitment or contract term is published on the site; the only route to a figure is a demo booking
  • IFS Cloud is sold as an industry specific composable suite rather than as a priced product with published editions

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

IFS: Why is IFS P2 Energy Solutions pricing not published?

IFS provides custom pricing based on organization size and specific needs. The website directs interested buyers to book a demo or contact the sales team rather than publishing standard rates.

Source
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.

IFS: What is the process to get pricing information from IFS?

The website includes calls-to-action for 'Book a demo' and 'Contact us' as the primary pathways to discuss pricing and contract terms with the sales team.

Source
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.

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.

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.
