If you run an architecture firm in Massachusetts or New Hampshire, there is a good chance part of your BIM 360 license cost is paying for people who never design anything in your projects. Structural engineers, MEP consultants, surveyors, owner reps, and outside vendors all need to see your files, and somewhere along the way each of them ended up with a seat. This post explains how that happens, how to tell which seats are truly needed, and what changes when outside sharing stops requiring a license.

Why seat counts keep climbing

Nobody sets out to overbuy licenses. Seat counts grow one reasonable decision at a time.

A new project starts, and the structural consultant needs to review the model. Someone adds a seat so they can get in. The project closes, but the seat stays. Six months later, the same thing happens with a landscape architect, a code consultant, and a client’s facilities manager.

Here is how the pattern usually builds:

• Project-driven additions. Seats are added fast to keep a deadline moving, and nobody owns the cleanup afterward.
• Consultant turnover. Outside teams change from project to project, but their access often lingers.
• No single owner. Project managers request access, office managers pay invoices, and no one compares the two lists.
• Fear of breaking something. Removing a seat mid-project feels risky, so it never gets removed.

The hidden cost of access-only seats

When a seat exists mainly so someone outside your firm can open a file, you are paying for access rather than for design capacity. That distinction matters because the two needs are very different.

A designer who builds and edits Revit models every day uses a seat all day. A mechanical engineer who opens the model twice a month to check clearances does not. Yet on the invoice they look identical.

The costs go beyond the license line:

• Paying for idle seats. Dormant accounts keep billing until someone notices.
• Administrative drag. Every added and removed outside user is another ticket, another approval, another thing to track.
• Security exposure. Every outside account is a door into your project data. Accounts that outlive their projects are doors nobody is watching.
• Project friction. Waiting days for a consultant’s access to be approved slows reviews and frustrates clients.

If the main reason a seat exists is so someone can look at a file, the real question is whether your firm should be paying for that seat at all.

How to tell which seats are really needed

You do not need a consultant to start. A short internal review will show where most of the waste is. Work through these questions for every seat on the account.

Sort every seat into one of three groups

• Core production. Your own designers, drafters, and project leads who author and edit models and drawings. These seats earn their keep.
• Occasional internal. Staff who review, comment, or approve a few times a month. Worth a second look at whether they need a full seat.
• External access. Consultants, vendors, contractors, and client contacts who mainly view or download. This is where most unneeded spend hides.

Ask five pointed questions about each external seat

• When did this person last open a project file?
• Is the project they were added for still active?
• Do they edit anything, or only view and download?
• Who at our firm approved this seat, and do they still work here?
• Would the project stall if this access disappeared tomorrow?

Most firms find a meaningful share of external seats fail the first two questions. Those are your quickest wins.

Check the calendar, not just the headcount

Look at seat usage across a full year, not a single busy month. A seat that was essential during construction administration may sit unused for the rest of the year. Firms with 50 to 300 employees often carry the most of this drift simply because they run more concurrent projects with more outside teams.

What changes when sharing no longer needs a seat

The cleanest way to cut BIM 360 license cost is to remove the reason those external seats exist in the first place. When consultants and vendors can reach the project files they need without being assigned a seat, the equation shifts.

Here is what firms notice when outside sharing stops being tied to licensing:

• Seat counts match real design work. You pay for the people building the models, not everyone who needs to see them.
• Faster consultant onboarding. A new engineer can be working with the files the same day instead of waiting on an access request.
• Cleaner offboarding. When a project ends, outside access ends with it, without a license cleanup chore.
• Fewer surprises at renewal. There is no scramble to explain why the seat count crept up again.
• Less administrative load. Project managers stop filing seat requests for every new outside party.

The outcome is a licensing picture that reflects how your firm actually works, with outside collaboration treated as a normal part of every project rather than a recurring line item.

Practical next steps

You can make progress this month without changing any tools. Start here:

• Export your current seat list and mark each one as core production, occasional internal, or external access.
• Flag every external seat tied to a closed or dormant project.
• Name one owner for seat reviews so the list gets compared against active projects on a regular schedule.
• Set a calendar reminder to repeat the review before each renewal, not after.
• Talk to your IT partner about how external collaboration is handled today and whether it has to depend on licensing at all.

Architecture, engineering, and construction firms across Massachusetts and New Hampshire face this same pattern, as do small-to-mid-sized businesses across other industries that share files with outside parties. As the trusted managed IT partner for the region, we help firms take a clear-eyed look at where their software spend goes.
