For commercial subs bidding through Procore, BuildingConnected and email

Change tradeEvery floor of a building like this was priced trade by trade, by subcontractors, often off a set that changed before bid day. One addendum can touch six trades at once.
Each red cloud on the photo is one changed sheet. Under each sheet: the trades it affects.
Opsync makes sure the change to your sheets reaches the person doing your takeoff.

Every trade prices its work in its own software. The invitations, addenda and follow-up around it look the same in every trade. Pick yours.
The lighting rep holds the number until bid day, and Addendum 4 just revised the fixture schedule.

Keep Accubid. Keep FastDUCT. Keep WinBidPro. Keep whatever prices your work.
Mechanical and plumbing under one roof? Each division keeps its own estimators, GC list and travel radius, on the same invitation.
One building goes out to bid through four GCs, three portals and somebody’s inbox. Opsync puts every invitation on one board in your own Sheet, grouped under the job it belongs to.
The rules your estimators already apply, written as plain sentences in a Sheet you can edit. Every invitation is checked before anyone opens the drawings. You still make the call.
No-bid if more than four GCs are bidding it.
No-bidNo-bid if it’s over 90 miles away, unless our scope is over $750,000.
No-bidFlag it if there are fewer than 3 working days to bid.
FlagHold it if the GC has never sent us results.
HoldEach rule is a sentence in a cell. Change the sentence, change the rule.

Sample data. Not a client.A bid board app collects invitations inside one platform. A Zapier automation copies an email into a row. Neither applies your GC-by-GC rules, groups the same job across Procore, BuildingConnected and email, routes an addendum to the person holding the takeoff, keeps one current set, or chases results. Opsync builds all of it in your account. If one board covers you, use it.
A real build for a commercial metal and glass subcontractor in the Northeast US. The trade was glass. The paperwork was the same as yours: invitations from three sources, rules, addenda, drawings and follow-up.
Ask about this build on the call.
Opsync is one person. I’m the person on the assessment call, the person who builds your system and the person you email afterwards.
You email me, not a sales team.
Opsync is not an estimating service, and I’ll never ask you to send plans for a quote.
Wasim Sajjad, Opsync
Every example on this page is sample data, except the client build above.
It does part of it, inside Autodesk’s system. Bid Board Pro collects BuildingConnected invitations and forwarded emails. Opsync puts Procore, BuildingConnected and email invitations on one board in your own Sheet, applies your written rules, and routes each addendum to a named person. If Bid Board Pro alone covers you, use it.
No. Accubid, FastDUCT, WinBidPro, On-Screen Takeoff or whatever prices your work stays exactly as it is. Opsync handles the invitations, rules, addenda, drawing sets and follow-up around the estimate. It never builds or changes your number.
There’s nothing new to log into. It’s the Sheets, Gmail labels and Drive folders your estimators already open, built around the rules they already use.
Fair question. You deal directly with the person who builds it. Everything is built in your accounts and visible to your team: sheets, folders and rules you can read. I’m not an estimating service, and I’ll never ask you to send plans for a quote.
Everything is built in your Google Workspace, under your account. Your team can read every rule and every sheet, because they are plain Sheets, folders and labels.
Only what you choose to send them, like a decline or a follow-up.
In your Google Workspace: your Sheets, your Drive folders, your Gmail labels. You own all of it. I work in your accounts with the access you grant.
A fixed quote, in writing, before any work starts. The number depends on how many places your invitations come from and which of the six pieces you want. The 20-minute assessment is free.
It depends on your sources and how many of your rules exist already. The quote comes with a written schedule.
No. Bring last month’s ITBs. A list or a few forwarded invitations is enough.
General contractors. Residential builders. Shops that price every invitation they get. Opsync builds inside Google Workspace. If your office runs on Microsoft 365, ask before you book.
In 20 minutes we’ll go through which of them your own rules would have skipped and where an addendum could have slipped. No plans needed. A fixed quote follows in writing.
