What it does: AI takeoff model from Y Combinator-backed Handoff that reads construction drawings and produces material quantities automatically. Live inside the Handoff product and available via API (
[email protected]). In testing it outperformed human estimators on speed and accuracy, and is already used by a large supplier across all its locations.
Legacy alternative: Manual takeoff, PlanSwift / On-Screen Takeoff, spreadsheet tallying
Key differentiator: A dedicated AI takeoff model (not just a tool) with an API — so it can be embedded into PGC's own estimating pipeline, not just used as a standalone app. Proven to beat human estimators in controlled tests.
Pricing: Not public (SaaS + API usage-based)
Glazing applicability: High — AI takeoff that can be pointed at glazing shop drawings and window schedules for unit counts and sizing
MVP trial: Request API access and run a set of PGC glazing drawings through the Handoff H1 model

What it does: Browser-based takeoff and job-costing workspace with an AI agent (Onyx) that detects rooms, calibrates scale, measures quantities, estimates costs, and even generates invoices. Launched on Product Hunt ~3 days ago.
Legacy alternative: Manual takeoff, desktop estimating tools, disconnected invoicing
Key differentiator: The Onyx AI agent handles the full loop — from reading a plan to producing an invoice — in one workspace. Combines takeoff, estimating, and billing that are usually separate tools.
Pricing: Not public (likely subscription, early-stage launch pricing)
Glazing applicability: High — AI-driven takeoff and job costing that can be applied to glazing projects end-to-end, from plan to invoice
MVP trial: Upload a glazing project plan, let Onyx measure quantities, and review the estimate + invoice output
Try Now
What it does: Open-source construction ERP (AGPL-3.0, v3.0) with BOQ, PDF/CAD/BIM takeoff, AI cost matching, 71 modules, 42 regional catalogues, and 21 languages. Installable via pip install openconstructionerp. GitHub: datadrivenconstruction/OpenConstructionERP.
Legacy alternative: Sage, QuickBooks + spreadsheets, proprietary construction ERPs
Key differentiator: Free and open-source with no license fees — full ERP + takeoff capability at zero software cost. Regional catalogues and AI cost matching make it adaptable to local glazing pricing.
Pricing: Free (open-source, AGPL-3.0); self-host or paid support
Glazing applicability: High — Full ERP with takeoff and cost matching for a make-to-order glazing/fabrication shop, at zero license cost
MVP trial: pip install openconstructionerp and load a sample glazing BOQ to test takeoff and cost matching

What it does: Exclusive integration between STACK (cloud takeoff/estimating) and Velixo that connects takeoff and estimating data directly inside Excel. Launched ~2 weeks ago. Lets estimators pull live STACK quantities into Excel formulas and reports.
Legacy alternative: Manual re-entry of takeoff numbers into Excel, disconnected estimating + spreadsheet workflows
Key differentiator: Bridges the gap between cloud takeoff and the spreadsheet where most estimators still do their pricing — live data, no copy-paste, no version drift.
Pricing: STACK subscription (modular, transparent public pricing) + Velixo license
Glazing applicability: Medium — Useful if PGC's estimators price glazing takeoffs in Excel and want live STACK quantities flowing in
MVP trial: Trial STACK + Velixo with a glazing takeoff, build an Excel pricing sheet pulling live quantities

What it does: AI-automated blueprint takeoff that reads site plans and spec sheets to deliver accurate material quantities without manual tracing. Hybrid model combines AI processing with human expert review, delivering finished estimates rather than raw takeoff data. G2-rated 4.9/5.0 from 30 reviews (July 2026).
Legacy alternative: Manual tracing, PlanSwift, spreadsheet takeoff
Key differentiator: Delivers finished estimates (not just quantities) via a hybrid AI + human-expert review model — accuracy of AI with the judgment of experienced estimators. Strong G2 rating.
Pricing: Not public (managed service / subscription)
Glazing applicability: High — AI takeoff with human review that can handle glazing and façade scope for accurate material quantities
MVP trial: Submit a glazing project's plans and spec sheets for a sample AI takeoff + expert review
Try Now
What it does: AI-native estimating tool that builds and prices a bid with an assistant that speeds up takeoff and line-item detail, then turns the numbers into a client-ready proposal. Aimed at contractors who want estimating and proposals in one place.
Legacy alternative: Manual estimating, separate takeoff + proposal tools, spreadsheets
Key differentiator: AI assistant drives the whole bid — from takeoff to line-item pricing to a polished client proposal — in a single AI-native workflow.
Pricing: Not public (subscription)
Glazing applicability: Medium — AI bid building that can be applied to glazing scope, from takeoff to client-ready proposal
MVP trial: Build a sample glazing bid with the AI assistant and review the proposal output
Watch
What it does: Visual intelligence platform for builders that captures 360° site imagery and maps it to plans, creating a visual record of the job. Waypoint 2026 (its annual conference) registration is open, signaling active product development.
Legacy alternative: Manual progress photos, site walkthroughs, disconnected documentation
Key differentiator: Continuous 360° site capture mapped to drawings — a searchable visual timeline of the project that anyone can review remotely, reducing site visits and disputes.
Pricing: Not public (per-project / subscription)
Glazing applicability: Medium — Visual documentation of glazing installs and curtainwall progress for QA, punch lists, and client records
MVP trial: Capture a glazing install site with OpenSpace and review the mapped visual record
Watch
What it does: Latest version of A+W Software's ERP platform for door and window manufacturers, demonstrated at GlassBuild America (Fall 2026). Connects production data with financial performance, giving manufacturers a single view from order to cash.
Legacy alternative: Disconnected production + accounting systems, spreadsheets, generic ERP
Key differentiator: Purpose-built for door/window/glass manufacturers — connects production data directly to financial performance, closing the shop-floor-to-accounting gap.
Pricing: Not public (enterprise ERP, per-seat)
Glazing applicability: High — ERP built specifically for door/window/glass manufacturing, connecting production to finance for a glazing/fabrication shop
MVP trial: Request an A+W demo focused on PGC's order-to-cash flow for fabricated glazing units

What it does: Purpose-built ERP and MES platform for insulated glass unit (IGU) manufacturers and glass processors. Supports complex IGU configurations, QR code traceability at the component level, integrated quoting, production scheduling, and CE documentation.
Legacy alternative: Manual IGU config, spreadsheets, generic ERP without glass-specific MES
Key differentiator: Built specifically for IGU/glass processing — component-level QR traceability and complex IGU configuration that generic ERPs can't handle.
Pricing: Not public (subscription)
Glazing applicability: High — IGU-specific ERP/MES with component traceability, directly relevant if PGC fabricates insulated glass units
MVP trial: Request a demo with PGC's typical IGU configurations and traceability requirements

What it does: AI takeoff tool that measures areas, counts, and lengths from construction drawings with a single click. Widely cited as the gold standard for AI takeoff in 2026, with a flat $299/mo pricing model.
Legacy alternative: Manual takeoff, PlanSwift, On-Screen Takeoff
Key differentiator: One-click AI takeoff at a flat, transparent $299/mo — no per-project or per-seat complexity. Consistently rated the benchmark for AI takeoff speed and accuracy.
Pricing: $299/mo (flat)
Glazing applicability: Medium — Fast AI takeoff for glazing scope; general-purpose (not glazing-specific) but proven and affordable
MVP trial: Run a glazing project's drawings through Togal.AI's one-click takeoff and compare to manual counts
