- You need deal flow. PlanHub's network — it reports 400,000+ subcontractors and tens of thousands of GCs — exists to surface projects and fill bid lists.
- You're a GC posting projects and soliciting sub coverage — PlanHub's GC access is free, which makes it an easy default for solicitation.
- You're a sub whose main problem is finding the right invitations in your trade and radius, and a lead subscription pays for itself on one won job.

PlanHub vs BuildBid
PlanHub is a plan room and bidding network — it helps GCs fill a bid list and helps subs find work. BuildBid starts after the invitation lands: AI-extracted quantities, source-linked review, and the proposal. One finds the bid; the other produces it.

ITB trade packages level sub quotes against a common baseline
The point is not a prettier measurement screen. It is a bid record where quantity, confidence, source evidence, and correction history stay together.
- Your problem starts after the invitation: the plan set is in hand and you need quantities, pricing, and a proposal before the deadline.
- You want AI extraction with source-linked rows and confidence flags — PlanHub's takeoff and estimating add-ons are operator-driven measurement tools, not review-first extraction.
- You want sub quotes collected against your own reviewed line items (BuildBid's ITB links) so leveling starts from a common baseline.
DECISION TABLE6 CHECKS
| Decision | PlanHub | BuildBid |
|---|---|---|
| Primary job | Find the work: plan room, project discovery, invitations to bid, sub and supplier network. | Produce the bid: plan set in → reviewed, source-linked estimate and proposal out. |
| Where it sits | Before the bid package is in hand — deal flow and solicitation. | After the invitation lands — takeoff, estimate, scope review, proposal. |
| Takeoff and estimating | Cloud takeoff and estimating available as paid add-ons with a large item cost library — operator-driven measurement. | AI extraction is the default starting point; the estimator reviews by confidence instead of tracing. |
| Sub quotes | Solicitation across a national network — including subs you don't know yet. | ITB links collect quotes from your subs against your reviewed line items; not a discovery network. |
| Pricing model | Free for GCs; subcontractor lead plans from about $1,999/year by coverage radius (as of mid-2026). | Tier-based credits aligned to estimate volume; no-login try flow. |
| Best fit | Teams whose constraint is deal flow and bid coverage. | Teams whose constraint is producing a defensible number once the package arrives. |
WHY TEAMS SWITCH
Less handoff loss after takeoff.
- 01
Keep PlanHub for discovery and coverage; produce the estimate itself in a tool built for extraction and review.
- 02
Replace manual takeoff on won invitations with AI extraction the estimator verifies against the sheet.
- 03
Collect sub quotes against reviewed line items through ITB links instead of leveling five differently-shaped PDFs.
HONEST LIMITS
- BuildBid is not a plan room: it does not surface projects, invitations, or new subs — if deal flow is your constraint, PlanHub does a job BuildBid doesn't.
- BuildBid's ITB collects quotes from subs you invite; it has no directory or network for discovering subcontractors.
- No supplier network or material marketplace — pricing comes from your own data and review, not from marketplace feeds.
