Subcontractor Lien Waiver Tracker for General Contractors

Why This is an Opportunity

Lien waiver management is a compliance-critical workflow that directly gates cash flow on construction projects. Missing a single waiver can expose the property owner (and by extension the GC) to mechanics' liens. The current spreadsheet-and-email approach breaks down on projects with 20+ subcontractors across multiple pay applications. The solution is a simple CRUD app: projects → subcontractors → payment milestones → waiver status per milestone, with email reminders via Resend when waivers are overdue. No complex integrations needed — just forms, status tracking, and a dashboard showing which waivers are outstanding across all active projects. Buildable in one session with Next.js and a Postgres database.

Key Pain Points

  • Tracking conditional vs. unconditional waivers across 20+ subs per project using color-coded spreadsheet cells
  • Manually emailing each subcontractor every payment cycle to request waiver documents
  • No centralized view of which projects have outstanding waivers blocking final payment or project closeout
  • Paper waivers get lost, PDFs sit in email attachments with no searchable index
  • Project closeout delayed by weeks because one sub's waiver from three months ago was never collected

Original Discovery

On every commercial construction project, general contractors must collect conditional and unconditional lien waivers from every subcontractor before releasing payment — and again before closing out a project. Most GCs track these in a spreadsheet with columns for each sub, each payment application, and each waiver type, then chase down missing documents via email and text. A purpose-built web app where GCs create a project, add subs and payment milestones, and track waiver status (requested, received, verified) with automated email reminders would eliminate a massive administrative headache that currently burns hours every pay cycle.
