There are more facility management software companies than there are useful distinctions between them, and the feature grids are close to identical because they are all describing the same four objects: assets, work orders, schedules and history. The distinction that actually predicts whether a product will suit you is not on the grid at all. It is who the company built for, because that decides what is cheap and what is painful once your own building is in it.
The three groups, and how to tell which you are looking at
Enterprise platforms are sold to estates teams with dozens of sites and a procurement process, and they assume an implementation project. Mid-market maintenance products are sold to one facility with a handful of technicians and assume you will set them up yourself. Field service products are sold to contractors who visit other people's buildings and bill for it. The third group looks close and is not: everything in it is organized around the customer and the invoice rather than around the asset.
What the differences actually cost you
An enterprise platform bought for one building means paying for configuration you will never use and waiting on a partner to change a field. A field service product means recording your own technicians as though they were billing an external customer, which quietly corrupts your cost history. A mid-market product bought by an estate of thirty sites means hitting limits on reporting across buildings in the second year. Picking by group is the decision; picking by feature list is decoration.
The question to ask every one of them
Ask what an export contains and try it during the trial. Companies in every group answer this differently, and the answer tells you what they think the record is for. If what comes back is the asset list with condition, the work order history with dates and costs, and the schedule with what is due, the record is yours. If it is a formatted report, you are renting it, and the day you change supplier you will be rebuilding the register by hand.
Questions people ask about facility management software companies
Does a bigger company mean a safer choice?
It means a longer support queue and a lower chance of the product being discontinued. It does not mean a better fit. For one building the risk that matters is not the vendor failing, it is the product assuming an estates department you do not have.
How much should a single building expect to pay?
Enough to matter and not enough to need a business case, if the pricing is not per user. Per user pricing is the thing to watch: it charges you for exactly the behavior you want, which is every technician and contractor filing what they did.
Are the free tiers worth starting on?
For the arithmetic, yes. The condition index, the backlog and the annual plan are calculations and need no subscription. A free tier stops being enough on the day you need to prove when something was last serviced.
