iSqFt vs ConstructConnect: what is the difference?
iSqFt is now part of ConstructConnect. Here is what each name refers to today, what the combined product does, and what to weigh if you're deciding whether to stay on it.
The confusion is understandable. iSqFt was one of the first online plan rooms for GCs, a lot of people still call the product by that name, and ConstructConnect has rebranded and reorganised more than once since the merger. This article sorts out the names and then gets to the practical question: is the bundle worth what you're paying?
Descriptions are from ConstructConnect's public materials as of September 2026. Confirm details with the vendor.
iSqFt and ConstructConnect: the short history
- iSqFt started as an online bid management and plan room service for general contractors.
- ConstructConnect was formed in 2016 by combining iSqFt, BidClerk and CMD (construction data). iSqFt became a product inside it.
- SmartBid, another bid management tool, joined ConstructConnect in 2019.
- Since then, the bid management functions have been consolidated and rebranded. iSqFt users were migrated onto the ConstructConnect platform; you may see references to iSqFt, SmartBid or ConstructConnect Bid Management depending on how old the page is.
So there is no "iSqFt versus ConstructConnect" decision to make. There is a ConstructConnect decision, and iSqFt is one part of it.
What ConstructConnect sells today
Roughly three things, often bundled:
- Project Intelligence (leads). Who is building what, where, and when it goes to bid. This is the data business that came from CMD and BidClerk, and for many subscribers it's the main reason they pay.
- Bid management (the iSqFt and SmartBid lineage). Post a project, distribute plans, invite subs from your own list or their network, track who has downloaded and viewed.
- Takeoff and estimating. On-Screen Takeoff and related tools.
Who the bundle suits
- GCs who genuinely use the lead data to find work
- GCs who bid in several regions and rely on the network to find subs
- Teams who want plan distribution, invitations and takeoff from one vendor
Where GCs say it chafes
From public reviews and the conversations that prompt people to search this question:
- The interface has changed through the mergers, and long-time iSqFt users have had to relearn it more than once.
- Invitations arrive from a ConstructConnect address, and some subs treat them as sales email.
- Downloads and views are tracked, but "who is actually bidding" can be harder to see at a glance.
- Paying for leads in regions you don't build in.
- Renewal increases.
Notice that most of these are about the bidding workflow, not the data. That tells you where to look.
Three ways to go
1. Stay, and use the bundle
If you use leads, bidding and takeoff every week, the bundle is reasonable. Ask for a usage report before renewal so you know that's actually true.
2. Keep the leads, change the bidding
Project intelligence and bid invitations don't have to come from the same vendor. A GC that values the data can keep a leaner ConstructConnect data plan and send invitations with something built for that. The best option for this is Invite All, our product: it sends one tracked invitation per person from your own Microsoft 365 or Google Workspace mailbox, gives each sub a private link with the drawings and Bidding / Maybe / Not bidding buttons (no account, so no more "is this a sales email?"), and shows delivered, clicked, viewed and answered per contact. It doesn't do leads, so it sits neatly beside a data subscription. Other options are BuildingConnected (large network, quoted pricing), Pantera Tools (lighter, plan room included), or an Outlook mail merge with a tracking spreadsheet.
3. Leave for a full platform
If what you actually want is bidding integrated with project management, that's a Procore or Autodesk Construction Cloud conversation, and the bidding module should be a minor factor in that choice. Procore's pricing model, explained.

How to evaluate without losing a month
- Export your trade list from ConstructConnect first. You'll need it whatever you decide, and you'll learn how clean it is. How to fix it if it isn't.
- Count real usage for the last quarter: projects posted, invitations sent, leads pursued.
- Ask three subs, one large, one medium, one small, what they think of your invitations.
- On any demo, insist on seeing the sub's email with the From line, an addendum sent to everyone still bidding on one scope, and a live list of who hasn't opened an invitation.
- Then price.
iSqFt was a good product. ConstructConnect is a data company that also does bidding. Decide based on which of those you're actually using.
