Buildxact is great at takeoffs and quotes (from $199/mo). Cornerstone PMTM is the Buildxact alternative that adds full construction management: scheduling from $149/mo, homeowner portal, purchasing, bid management, options engine (Builder $299/mo), and Foreman AI with 100+ action-taking skills (Pro $499/mo) - all in one platform.
Buildxact vs Cornerstone PMTM - takeoff tool vs. full home-builder platform.
| Feature | Cornerstone PM™ | Buildxact |
|---|---|---|
Built for home builders Buildxact is takeoff/estimating software popular with custom builders and remodelers. Cornerstone is a full PM platform built across the home-builder spectrum - production, semi-custom, and custom - with lot management, options engine, and multi-community pipelines. | ||
Full construction PM platform Cornerstone: scheduling, purchasing, bid management, homeowner portal, options engine, multi-community pipeline. Buildxact: primarily estimating and quoting; scheduling is an add-on feature. | Limited | |
AI floor plan takeoffs (Blueprint AI) Both do floor plan takeoffs. Cornerstone Blueprint AI (Pro $499/mo) converts PDF blueprints to material takeoffs in under 60 seconds. Buildxact has Blu AI Takeoff Assistant (add-on, ~$99/mo on Pro plan). | ||
Native AI agents (Foreman AI - 396+ skills) Cornerstone Pro ($499/mo): Foreman AI reads AND writes construction data - POs, options, SOWs, bid comparisons, image search, web scraping. Buildxact has 'Blu' AI for estimating assistance (assembly help, estimate generation). Different scope: action agent vs estimating aid. | Limited | |
AI memory compaction for marathon sessions Foreman auto-summarizes older messages so long workflows never crash or forget. No other construction AI does this. Cornerstone Pro feature. | ||
AI image search, vision & anti-bot web scraping Foreman searches product images, hosts them on CDN, reads supplier product pages with AI-powered web scraping. Plus: paste or drag-drop any screenshot from inside the app and Foreman reads it with AI vision and acts on it. Cornerstone Pro feature. | ||
37+ named webhook events (catalog growing) Cornerstone Pro+ ($599/mo): 37+ named events and counting - typed payloads, HMAC signatures, delivery logs, auto-retry. New events ship as the platform grows. Buildxact has no public webhook catalog. | ||
BYOA (Bring Your Own Agent) Cornerstone Pro+ ($599/mo): wire Claude or ChatGPT to your live construction data. | ||
Public REST API (150+ API endpoints) Cornerstone Pro+: 150+ API endpoints, public docs. New endpoints ship as the platform grows. Buildxact: limited API access. | Limited | |
Structural options engine Pre-sale options pricing matrix per floorplan - Cornerstone Builder ($299/mo). Not a Buildxact feature. | ||
Designer Packages (64 curated by an interior designer, 7 categories) Packages curated by an actual interior designer - the same playbook K. Hovnanian Homes uses. Buyers pick a package; all category options auto-lock. Cornerstone Builder+. | ||
AI Migration Wizard AI auto-detects column mapping and runs 23 import endpoints. ~$0.01 per migration. | ||
Take your data with you anytime - no lock-in Your data is YOURS. Full database export to CSV or JSON anytime, one click, $0, no fees, no waiting on a support ticket. Nightly auto-backups retained 7 days for instant rollback. If you ever leave us, you leave with everything - vendors, homes, schedules, options, budgets, every line. No strings attached. | ||
Vendor portal - no login required (email magic links) Vendors confirm tasks, accept schedule changes, and submit bids - all via secure magic links sent straight to their email. No app to download, no account to create, no password to remember. Click the link, do the thing, done. Biggest friction-killer for trade partners in the industry. | ||
Triple QR ecosystem (vendor + PM + buyer, no app install) Three QR codes for three audiences, no app required: (1) vendor jobsite check-in captures GPS + timestamp + weather + photo upload automatically, (2) PM/internal-builder check-in feeds GPS-validated timesheets so you can prove who was actually on-site, (3) sales model home QR for walk-in buyer lead capture - replaces paper sign-in sheets, recognizes returning visitors, instantly creates a Lead record tied to the community with email + in-app notification to the sales agent. Buildxact ships none of these. | ||
Sales model home QR — walk-in buyer check-in + auto Lead DB save One QR at every model home entrance: walk-in buyers self-register on their own phone, returning visitors are recognized, every scan auto-creates a Lead record (name, email, phone, "how did you hear about us?") tied to the community, and the assigned sales agent gets an instant in-app + email notification. Replaces paper sign-in sheets with a searchable, attributable lead pipeline. Buildxact has no model-home lead-capture flow. | ||
Vendor Activity Map (Google Maps, real-time) Live Google Maps view of every vendor check-in across every community, 30-second refresh. See exactly who's on which jobsite right now. Filter by date or vendor. Stat cards show how many vendors are currently on-site. Buildxact has no equivalent. | ||
Flexible PO generation (4 patterns, mix on same job) Most platforms hard-code one PO model. Cornerstone gives you four: (1) all POs at job start (lock in budget exposure day one), (2) partial deposit POs from earlier pipeline tasks (permit pull, contract sign, foundation pour), (3) full PO auto-generated when a construction task is marked complete (cash goes out only when work is verifiably done), or (4) configurable per task / scope / community - mix all four on the same job. Buildxact is takeoff/estimating-first - not a full PO orchestration platform. | ||
Homeowner portal (realtime sync + photos + messaging + ZIP export) Real-time portal synced with construction scheduling - when framing moves three days, buyers see it instantly. Plus: (1) builder/PM uploads job-site photos to every milestone (up to 5 photos per milestone via a camera button on the task row), (2) built-in messaging app between builder and customer with a permanent searchable record, and (3) one-click ZIP download of all job photos. Buildxact is takeoff/estimating-first - no buyer-facing portal of this depth. | ||
Multi-community management Native multi-community pipeline. Buildxact is job-focused, not community-focused. | ||
Construction scheduling Cornerstone: full Gantt, dependencies, cascade scheduling (Starter+). Buildxact: scheduling included on Pro plan ($399/mo) up. | Limited | |
Takeoff / estimating Both include takeoff and estimating functionality. | ||
Generous user caps Cornerstone: up to 30 users (60 on Pro+). Buildxact: unlimited (Foundation starts at $199/mo annual). | ||
Pricing model Both are flat-fee within tier. Cornerstone: up to 30 users (60 on Pro+) from $149/mo. Buildxact Foundation starts at $199/mo (annual) for estimating/takeoffs; Master $599/mo plus Blu AI add-ons. More importantly: Buildxact doesn't ship an options engine, floorplan pricing matrix, multi-community pipelines, homeowner portal, or action-taking AI agents at any tier. | Flat - up to 30 users (60 on Pro+) | Flat, unlimited users (higher starting price) |
Cornerstone tiers (flat - up to 30 users • 60 on Pro+) Starter ($149): scheduling, permits, homeowner portal. Builder ($299): adds sales pipeline, purchasing, design center with options engine and designer packages. Pro ($499): adds Foreman AI + Blueprint AI. Pro+ ($599): adds REST API, BYOA, 37+ named webhook events, 7-wave bidding. | $149 / $299 / $499 / $599 | - |

Blueprint AI converts PDF floor plans to material takeoffs in 60 seconds. Foreman AI (396+ skills on Pro $499/mo) reads and writes your data - SOWs, bid comparisons, design options, image search, web scraping. Buildxact's Blu AI stays within estimating scope.
Built-in MCP server (connect Claude Desktop, Cursor, or Windsurf in ~30 seconds), 37+ named webhook events with typed payload schemas, HMAC signatures, and auto-retry on Pro+ ($599/mo) - catalog growing. Public REST API with 150+ API endpoints. Wire your own tools, SMS bots, or AI agents. Buildxact has no comparable automation layer.
