Where each one falls short

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

Maintenance Connection

  • Implementation is a project measured in months, and the cost of that work frequently exceeds the first year of licensing
  • Pricing is entirely quote-based with no published entry point, so early comparison is impossible
  • The interface reflects its age and is a common objection from technicians used to consumer-grade mobile apps
  • Overpowered for single-site operations, where the configuration burden buys capability that will not be used
  • Accruent sells a broad portfolio, so the buying process involves more product than a maintenance team asked for

SOS Inventory

  • The Companion plan at $69.95 per month is limited to a single location and 1 custom field
  • Serial and lot number tracking, barcoding and unlimited locations require the Plus plan at $139.95 per month
  • Phone support is excluded from the Companion plan
  • Job costing, advanced manufacturing and the customer portal require the Pro plan at $194.95 per month
  • Each plan includes only 2 to 5 users and additional users cost $25 each per month
  • The 2 months free discount requires paying a year up front

Answered from the vendors’ own pages

Maintenance Connection: Who is Maintenance Connection for?

Multi-site organisations with large asset registers and formal maintenance governance. Below that scale, the configuration effort is not repaid.

SOS Inventory: How much does SOS Inventory cost?

SOS Inventory offers monthly plans from $69.95 for Companion to $194.95 for Pro. Annual billing saves approximately two months of fees. Additional users cost $25/month, and external connections are $25/month each.

Source
Maintenance Connection: What does it cost?

Not published. It is quoted, and implementation is a separate line that often exceeds first-year licensing.

SOS Inventory: Does SOS Inventory offer a free trial?

Yes, SOS Inventory offers 14 days to explore its full range of features. Users can upgrade or downgrade plans easily through account settings.

Source
Maintenance Connection: How does it differ from MaintainX?

Almost entirely. This is an enterprise system configured to enforce an existing process; MaintainX is a mobile app a team adopts in a day. They rarely appear on the same shortlist honestly.

SOS Inventory: What is the difference between SOS Inventory plans?

Companion includes 2 users and basic management. Plus is marked most popular and adds unlimited locations and lot tracking with 3 users. Pro adds advanced automation and manufacturing with 5 users.

Source
Maintenance Connection: Is it good for regulated industries?

That is its strongest case. Audit trails, evidence of preventive regimes and multi-site consistency are what it is built to produce.

Maintenance Connection: What is the biggest risk in adopting it?

Under-resourcing implementation. A partially configured enterprise CMMS is worse than a well-run simple one, and this is the most common way these projects disappoint.
