Key Features

48+ Trade Calculators

Professional-grade estimation for Concrete, Framing, Roofing, and more. Slab and footing volume, wall studs, rafter length, shingle bundles, pitch & slope, insulation R-value, trim, flooring, and business/margin tools — all tuned for field use.

Field Notes

Native contractor guidance hub with on-site articles for regional tax, estimating, and field planning topics. Content lives in-app and stays tied to the calculator workflow.

Field Access

Mobile install prompts are available for field use, and the app now uses a custom service worker to support a more app-like PWA experience with offline fallback, install shortcuts, and update-aware field access.

Account Security

Email/password accounts can enable email 2FA with a 6-digit code flow. Codes are delivered through Resend using a lightweight branded HTML template and expire after 5 minutes.

Sentry Audit

Full-context error reporting for field failures. Calculator inputs and trade context are attached to errors so issues can be reproduced and fixed quickly.

Regional Coverage

Built around Oneida, Madison, and Herkimer county workflows, including county tax defaults, estimate PDFs, and operator-friendly handoff guides.

Supabase Production Pooling

• Use SUPABASE_DB_TRANSACTION_URL for runtime database traffic. This should be the Supabase Transaction pooler on port 6543.
• Use SUPABASE_DB_SESSION_URL only for npm run db:push. This should be the Session pooler on port 5432.
• src/db/index.ts uses postgres plus Drizzle with max: 10 to avoid serverless connection spikes.
• drizzle.config.ts is intentionally pinned to the session URL so migrations do not run through the transaction pooler.
• Owner isolation for estimates is defined in estimates-rls-production.sql and mirrored in schema.sql.
