The short version

  • Each has a real cost: Omie specific plan pricing not listed; pricing varies based on company size and revenue; 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.
  • 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.

Omie

  • Specific plan pricing not listed; pricing varies based on company size and revenue
  • Pricing model defined as 'conforme o porte e o faturamento da empresa' (based on company size and revenue)
  • Offered in Portuguese only with Portuguese 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

Omie: How much does Omie cost?

Omie ERP pricing is determined based on company size and revenue rather than fixed tiers. Specific plan prices are not listed on the website; contact a consultant for pricing based on your business needs.

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.

Omie: Does Omie offer a free trial?

Yes, Omie offers a 7-day free trial at R$0.00 with no credit card required. The trial includes cloud-based system access, premium customer support, and full access to core features with quick cancellation available anytime.

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.

Omie: What is included in the Omie free trial?

The 7-day free trial includes a 100% online cloud-based system, premium customer support, simple online contracting, and full access to core features without credit card requirements.

Source
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.
