Fiix vs MaintainX
Fiix has no comparison programme. Not one page about any competitor. The result is that everything published about how Fiix compares was written by somebody selling an alternative — including three vendors who are not even in this matchup.
Who wrote this, and what we sell
We make ReportWalk, which is not a CMMS and does not compete with either product here. That is exactly why we can write this one. Neither company has any relationship with us.
The short answer
Fiix
Choose Fiix if a genuinely free tier and month-to-month billing matter, or if you are in a plant standardised on Rockwell Automation. Both are unusual at this end of the market and both survived the acquisition.
MaintainX
Choose MaintainX if mobile usability is the deciding factor and you want the product technicians will actually open. It is also free to start, which makes the comparison cheap to settle yourself.
Both have a free tier. This is one of the few software decisions you can resolve by using both for a fortnight instead of reading about them.
Who actually switched, and why
One documented switch, in one direction. Across our wider research Fiix appears as a consistent donor — several outbound records, none inbound from any named CMMS — though that pattern comes from sampled review corpora rather than from market data.
Fiix and Interix → MaintainX
“We made the switch from Fiix and Interix because we were experiencing poor customer service and felt the platforms were no longer evolving...”
The phrase 'no longer evolving' is doing a lot of work in competitors' marketing about Fiix. It is worth knowing that it originated with a customer rather than with a rival — and that it is one customer's impression.
Where they genuinely differ
Whether 'no longer evolving' holds up
It is worth testing the claim rather than repeating it. Fiix shipped an iOS release around 10 September 2026, added a mobile assistant in July 2026, and became an SAP build partner in March 2026.
A customer's perception of stagnation and a vendor's release history can both be real — a product can ship steadily and still not ship the thing that customer was waiting for. We would not tell you the criticism is baseless, and we would not tell you the product is dormant.
Pricing
Fiix publishes a free tier covering 25 active preventive maintenance schedules, then Basic at $45 per user per month and Pro at $75, with month-to-month billing available.
MaintainX publishes a free Basic tier, Essential at $20 per user per month annually and Premium at $65.
Offline, where both have a condition
Fiix says most mobile features work offline — and warns that logging out before the app syncs discards offline changes.
MaintainX requires an internet connection before switching to offline mode so it can build its cache. Prefetch, not offline-first.
Neither is a problem if you know about it. Both are if you do not.
What each is honestly better at
Fiix
Flexibility and industrial depth. Month-to-month billing and published per-seat pricing under a $9 billion parent are genuinely uncommon, and in a Rockwell plant the integration story is worth real money.
MaintainX
Being used by technicians rather than administrators. Mobile-first design is its consistent praise, and a free forever tier from a company valued at $2.5 billion is a low-risk way to test adoption before committing.
What we could not verify
- Whether Scott U.'s experience is representative. It is one account, and it is the source of a phrase competitors have amplified.
- MaintainX's complaint record is unusually thin for its size — we found one usable recent critical review anywhere — so we cannot present a balanced view of its unhappy customers.
- An observation we could not corroborate: fiix.com currently redirects to an unrelated lead-generation site while the live product sits at fiixsoftware.com. No source discusses this and we have not confirmed whether it is intentional.
- Reddit was unreachable in every research session.
If neither fits — a third shape of tool
If the part still on paper is the inspection round rather than the work order, that is a smaller tool than either of these. ReportWalk covers the walk and the document and has no work orders, parts or PM schedules.
