Multi-Division Home Builder Software: How Cornerstone PM Enterprise Works

Cornerstone PM™ Enterprise gives every division the full Pro+ platform—REST API, BYOA, all 396+ Foreman skills, 60 seats—plus a corporate layer with a division switcher, corporate admin, cross-division analytics, and an X-Division-Id scoped API. Pricing starts at $500/division/mo for the first five divisions, then $450/division/mo after that.

For regional builders and multi-brand operators, the home builder software category generally offers two disappointing options: standalone subscriptions with no shared layer across operating companies, or enterprise “call for pricing” tiers that strip out features to justify a custom contract. Cornerstone Enterprise is built on a different premise: every division gets the samePro+ platform it would get as a standalone subscriber, and the corporate layer adds on top of that—it never takes anything away.

Who is Enterprise designed for?

Enterprise is built for builders running two or more distinct operating divisions. This typically looks like:

• Regional home builderswith separate brand names or operating companies per market area—each with its own community pipeline, vendor relationships, and team structure.
• Multi-brand operators running an entry-level brand and a move-up brand as distinct legal entities, often with shared corporate overhead.
• Builder groups and holding companies that acquired several smaller builders and want consolidated visibility without collapsing them into a single account.
• Large production builderswith geographic divisions that operate semi-independently but report up to a single corporate P&L.

If you're a single-division builder building 5–200 homes per year, the standalone Pro+ plan at $599/mo is your tier. Enterprise pricing and the corporate layer only add value when you need the cross-division management and visibility layer.

What every Enterprise division gets

Every division in an Enterprise account gets the complete Pro+ platform. There is no stripped-down “enterprise division” SKU. That means:

• Full design center—64 curated Designer Packages, exclusion groups (pick one from many), per-floorplan option pricing reused across every home of that plan in every community. Design Center →
• Foreman AI with 396+ skills—the in-platform agent that reads and writes data, runs vendor analysis, generates profitability reports, manages purchasing workflows, and carries per-user memory across every session. Meet Foreman →
• Blueprint AI takeoff—parses a floor plan PDF and extracts 130+ material scopes with 3,284+ parts in under 60 seconds.
• REST API (150+ endpoints, 84 dedicated routes) across three schema formats: Anthropic, OpenAI, and OpenAPI 3.1.
• BYOA (Bring Your Own AI Agent)—every endpoint maps to one of Foreman's 396+ skills; ship a new Foreman skill and it auto-exposes to BYOA in every division with no configuration changes.
• 37 named webhook events with typed payloads, HMAC-SHA256 signatures, delivery logs, and auto-retry. Wire Twilio, Bland, Retell, or any webhook consumer to your build workflow.
• 60 seats per division.

The corporate layer: what Enterprise adds on top

Above the per-division Pro+ platform, Enterprise adds four corporate-layer capabilities:

Enterprise pricing: transparent and volume-tiered

Most enterprise software hides its pricing behind a sales call. Cornerstone PM Enterprise pricing is published publicly:

• $500/division/mo for the first 5 divisions
• $450/division/mo for every division after 5

Standalone Pro+ is $599/division. Enterprise pricing is a real discount from division #1—you're not paying more for the corporate layer. For a builder running 6 divisions, that's $2,950/mo versus $3,594/mo at standalone Pro+ rates—a $644/mo saving, plus the corporate layer on top.

The full pricing breakdown lives on the pricing page.

Pro+ vs Enterprise: feature comparison

Why enterprise tiers usually disappoint—and why this one is different

The standard enterprise playbook in construction software is to add a “corporate dashboard” on top of a crippled base tier, then quote $2,000–$5,000/mo per division after a six-week sales process. Builders running 5 divisions end up paying more per division for a worse product than a single-division subscriber gets.

Cornerstone Enterprise flips that. The rule is: every division gets Pro+, full stop. The corporate layer is the only thing Enterprise adds. The logic behind this is straightforward: a multi-division builder's biggest problem isn't that each division has too many features—it's that the divisions are siloed and there's no shared visibility layer. The fix is to add corporate visibility, not remove division capability.

This also means that when Cornerstone ships a new Foreman skill, it's available in every Enterprise division automatically—no per-division configuration, no feature-gating by tier within the enterprise account. The same denylist permissions model that makes BYOA auto-grow applies across the entire corporate account.

Foreman AI across multiple divisions

One of the more powerful aspects of Enterprise is how Foreman AI behaves at scale. Each division has its own Foreman context, including company-wide memory for that division's vendor relationships, plan standards, and purchasing patterns. But with the X-Division-Id API, a corporate AI agent (BYOA) can query across divisions—pulling comparative profitability data, normalizing vendor pricing across markets, or running cross-division schedule analysis.

This is the practical shape of what “AI-native construction management” looks like at the corporate level: not a single chatbot, but a skill catalog of 396+ purpose-built capabilities available to human users in every division and to external AI agents via the corporate API surface.
