The short version

  • Each has a real cost: AVEVA System Platform wonderware is no longer a name you can buy; if you have inherited documentation, purchase orders or job specifications that say Wonderware, everything has to be re-mapped to AVEVA product names before you can quote it.; 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 System Platform covers ArchestrA object model, 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 System Platform

  • Wonderware is no longer a name you can buy; if you have inherited documentation, purchase orders or job specifications that say Wonderware, everything has to be re-mapped to AVEVA product names before you can quote it.
  • AVEVA Flex converts licensing to a recurring subscription draw-down, so organisations that budgeted for a perpetual licence with a support percentage face a materially different cost model at renewal.
  • It is Windows only, and version compatibility between System Platform, Historian and InTouch is tight, so upgrades are coordinated projects rather than incremental patches.
  • The ArchestrA object model has a steep learning curve and small systems end up paying for structure they do not need, which is why integrators often deploy standalone InTouch instead.
  • Licence enforcement counts I/O aggressively and unexpected tag growth during commissioning can trigger a mid-project licence purchase at list price.

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 System Platform: Is Wonderware still sold?

No. The brand was retired; buy AVEVA System Platform, AVEVA InTouch HMI, AVEVA Historian or AVEVA Plant SCADA instead.

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 System Platform: Can I still buy a perpetual licence?

AVEVA steers new business to Flex subscriptions. Perpetual is increasingly restricted to existing agreements and renewals.

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 System Platform: Do my old InTouch applications still run?

Yes, legacy InTouch applications are supported in System Platform, though the older graphics do not gain the newer situational-awareness features without rework.

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.

AVEVA System Platform: What is AVEVA Flex?

A subscription credit pool you draw against for any AVEVA product, which trades a fixed licence for a recurring balance you must keep topped up.

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.
