The short version

  • Each has a real cost: Omnea it covers intake through contract only, so invoicing, payment and spend analysis remain with other systems and the promised end-to-end view is partial.; 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: Omnea covers Intelligent intake, Unit4 covers Flexible organisational model.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Omnea

  • It covers intake through contract only, so invoicing, payment and spend analysis remain with other systems and the promised end-to-end view is partial.
  • As a younger vendor its integration library is narrower than the established suites, and connections into older on-premise ERP systems may require custom work.
  • Pricing is entirely quoted with no published tiers, and the vendor is small enough that comparable public reference points are scarce.
  • Third-party risk depth is good for questionnaire-driven assessment but lighter than a dedicated GRC platform on continuous monitoring and control mapping, so heavily regulated firms may still need both.
  • Its value is concentrated in organisations with a formal procurement policy and a compliance obligation; a company without either gets an approval workflow tool at enterprise pricing.

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

Omnea: How does it differ from Zip?

Both do intake and approval orchestration. Omnea puts third-party risk assessment inside the same workflow and has a European base and compliance orientation, which matters under GDPR and DORA.

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.

Omnea: Does it replace our ERP?

No. It handles the request through contract stage and hands off to the finance system for purchase orders, invoicing and payment.

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.

Omnea: What does it cost?

Not published. It is an annual subscription quoted by company size and modules.

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.

Omnea: Do we still need a GRC tool?

Possibly. Omnea handles supplier due diligence well; continuous control monitoring and framework mapping remain a dedicated GRC job.

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.
