The Problem

Post-permit construction is a coordination nightmare

After a permit is issued, residential construction enters its most operationally complex phase. Builders juggle vendors, subcontractors, architects, inspections, and payments across tools that don't talk to each other. PostPermit fixes that.

  • Post-permit construction is fragmented across spreadsheets, email threads, and phone calls
  • Builders lose visibility the moment they hand off to vendors or subcontractors
  • Architect coordination happens outside the project record, creating gaps in accountability
  • Payment disputes arise from poor documentation of milestones and approvals
  • No single platform ties together RFQs, collaboration, and AI decision support

PostPermit solves this by...

  • Centralizing RFQs, quotes, and vendor selection in one place
  • Creating a structured architect collaboration and sign-off workflow
  • Tying payment releases to verified, approved project milestones
  • Giving builders real-time visibility across all active projects
  • Adding an AI assistant that guides decisions without removing control

Platform Features

Everything builders need in one workflow

01

Builder Dashboard

A centralized command center for builders to track all active projects, outstanding RFQs, vendor responses, and upcoming milestones in a single view.

02

RFQ & Vendor Quote Management

Create and send requests for quotes directly from the platform. Vendors respond within the system, keeping all communication structured and auditable.

03

Vendor Comparison & Recommendation Logic

Side-by-side vendor quote comparison with AI-assisted scoring to help builders identify the best fit based on price, timeline, and criteria.

04

Architect Collaboration Workflow

Architects can review scope, approve changes, leave feedback, and sign off on decisions — all within a structured approval workflow.

05

Payment Release & History Tracking

Milestone-based payment release tied to verified progress. Full payment history and audit trail for accountability and financing purposes.

06

Project Progress Visibility

Real-time visibility into what phase each project is in, which tasks are complete, and what is blocking forward progress.

07

Notifications & Activity Tracking

Configurable notifications for key events: vendor responses, architect approvals, payment milestones, and team activity across projects.

08

AI-Assisted Builder Guidance

An AI assistant that helps builders understand next steps, interpret vendor quotes, summarize project activity, and make better decisions faster.
