Where each one falls short

  • Steep learning curve, and Inductive Automation runs its own training programme because of it
  • Self-hosted and self-supported by default, so plant IT carries the availability burden
  • Module-based pricing means the entry figure is rarely the final one

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

Answered from the vendors’ own pages

Ignition: What does Ignition cost?

It publishes per-server module pricing with unlimited clients, tags and connections, so cost does not scale with how many people use it.

Megaventory: What is included in Megaventory's Pro plan?

The Pro plan costs $135 per month ($121.50/month with annual billing) and includes 5 users, 50,000 transactions, 20 locations, 20,000 product SKUs, 20,000 clients, and 2 hours of training.

Ignition: Why does unlimited-client licensing matter?

Traditional SCADA is licensed per tag or per screen, which turns adding an operator terminal into a purchase. Ignition removes that ceiling.

Megaventory: How much does Megaventory charge for additional users?

Megaventory charges $45 per month for each additional user, up to a maximum of 35 total users on the platform.

Source
Ignition: Is it a finished application?

No, it is a platform. Screens, tags and logic are built for the specific plant, which is real engineering work.

Megaventory: Does Megaventory offer a free trial?

Yes, Megaventory offers a 15-day free trial with no obligation to continue to a paid subscription. Non-profit organizations can contact Megaventory for discounted subscription rates.
