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.

Megaventory

  • Single Pro plan tier; no tiered options for different business sizes
  • Additional users cost $45 per month each up to 35 total users
  • Additional transaction blocks cost $45 per month per 25k transactions up to 200k total
  • Enterprise plan pricing requires contacting sales for custom quote
