The short version

  • Each has a real cost: AVEVA PI System pricing is not published and comes through an account representative; Flow Software the 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • They diverge on capability: AVEVA PI System covers Real-time data collection, Flow Software covers Calculation engine.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

AVEVA PI System

  • Pricing is not published and comes through an account representative
  • The vendor is moving to a subscription commercial model, so perpetual licence expectations no longer hold
  • Made up of several separately named components, including PI Server, PI Vision, Edge Data Store and the adapters and connectors needed per data source

Flow Software

  • The 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • The Unlimited licence requires every engine on a single server or VM, so any multi-server or multi-site topology goes straight to Distributed at roughly double the price with no intermediate option.
  • Maintenance renews at about fifteen percent of the installed base annually, so a large perpetual estate carries a five-figure recurring cost that the headline perpetual price hides.
  • It is a Windows product with a Microsoft data stack, so Linux or container-native deployment strategies do not apply and the server has to be managed on the plant Windows estate.
  • It calculates and reports but does not collect from equipment itself, so an existing historian or OPC layer is a prerequisite and Flow adds cost on top of that rather than replacing it.

Answered from the vendors’ own pages

AVEVA PI System: What is AVEVA PI System pricing?

AVEVA does not list PI System pricing on its website. AVEVA markets industrial software through enterprise sales channels with custom quotes.

Source
Flow Software: Does Flow publish real prices?

Yes. Starter is 11,390 USD perpetual for 250 measures, Unlimited is 62,230 USD perpetual or 16,595 USD a year, and Distributed is 128,450 USD perpetual or 34,250 USD a year.

AVEVA PI System: Does AVEVA offer a Flex Subscription Program?

AVEVA mentions Flex Subscription Program on its site for flexible product access, but pricing and terms are not published publicly.

Source
Flow Software: Is perpetual licensing still offered?

Yes, at every tier, with the first year of maintenance included and renewal at roughly fifteen percent per year. Subscription is available on Unlimited and Distributed only.

AVEVA PI System: Is AVEVA PI System available in the cloud?

AVEVA offers cloud options for its products, but per-seat or usage-based pricing for cloud deployments is not disclosed on the vendor website.

Source
Flow Software: Do I need a historian as well?

Effectively yes. Flow reads from historians, databases and OPC sources; it is a calculation layer, not a data collector.

Flow Software: What counts as a measure?

Each configured KPI or event definition. A single line typically consumes ten to thirty, which is what makes the 250 Starter cap tighter than it looks.
