Looking for a STACK alternative?
STACK is strong on on-screen takeoff for GCs and subs. PreconIntel is the other half of preconstruction — AI bid parsing, ITB workflow, Procore integration, and benchmarking built from your own bid history.

Subcontractor directory with win-rate scoring | Yes | Partial |
Permit-driven sub discovery | Yes | — |
Procore bidirectional integration Webhook-driven sync for vendors, commitments, COs. | Yes | Partial |
Cost benchmarking from bid history | Yes | Partial |
Side-by-side bid leveling with scope normalization | Yes | — |
Plan viewer & markup tools | — | Yes |
Comparison based on publicly documented features as of April 2026. STACK feature details may have changed; see their documentation for current capabilities. Not an independent third-party review.
When PreconIntel is the better fit
- →Your bid-day pain is parsing inbound bids, not generating takeoff from plans.
- →You award commercial work where MEP subs do their own takeoff — you just need to level the bids they send back.
- →You run on Procore and want a deep bidirectional sync.
- →You want win-rate and CO-risk scoring built from your own data.
When STACK is the better fit
- →You do your own conceptual takeoff from plans — STACK's on-screen measurement is best-in-class for GCs doing in-house quantities.
- →You're a specialty sub estimating directly off drawings rather than aggregating sub bids.
We don't think every GC should be a PreconIntel customer. When STACK is the right fit, we'll say so.
Frequently asked questions
Do you do on-screen takeoff?
Not today. STACK, PlanSwift, and OnScreen Takeoff are purpose-built for measurement from plans. PreconIntel starts after takeoff is done — when bids come back from the subs doing that work — and handles parsing, leveling, and Procore integration.
Can PreconIntel and STACK work together?
Yes. Many commercial GCs run STACK (or a STACK alternative) for conceptual takeoff, then hand the project to PreconIntel once ITBs go out. Both tools integrate with Procore and can share cost-code mappings.
What do you do that STACK doesn't?
AI bid parsing from email, AI-generated ITB scope notes, cost benchmarking that compounds from your bid history, permit-driven sub discovery, and bidirectional Procore integration. STACK's strengths are on-screen takeoff and plan markup — ours are the bid-day workflow.
How does pricing compare?
PreconIntel starts at $349/mo. STACK's base pricing is similar per-seat but scales differently depending on takeoff volume. Because the tools cover different phases, price isn't usually the deciding factor.
