The short version

  • Each has a real cost: Priority Software pricing is by quote only, with no published rate, minimum user count, contract term or add on cost for any of the Commercial, Manufacturing, POS or Optima PMS plans; 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: Priority Software covers Inventory, 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.

Priority Software

  • Pricing is by quote only, with no published rate, minimum user count, contract term or add on cost for any of the Commercial, Manufacturing, POS or Optima PMS plans
  • Point of sale, manufacturing and hospitality capabilities are sold as separate plans rather than one product

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

Priority Software: How much does Priority Software cost?

Priority Software does not publish specific pricing on their website. The site emphasizes custom solutions with the tagline 'Pricing plans that suit your business. Not the other way around.' Visitors are directed to speak with a sales expert for quotes.

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.

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.
