Built for Subcontractors

Clarity
Wins Contracts.

SubPro is a mobile proposal platform that decreases proposal creation time, to provide professional, structured proposals to clients.

What SubPro Provides

SubPro manages Time, Quality and Clarity from one platform with professional execution.

SubPro is a mobile app built for subcontractors to submit bids to General or Prime contractors for construction projects or direct to owners or end users. We replace the friction of late, incomplete, and unclear bids with structured proposals that give clients exactly what they need to award fast.

The Problem

  • Bids arrive late or miss deadlines
  • Scopes submitted are incomplete or ambiguous
  • Freeform proposals look unprofessional

The SubPro Solution

  • Deadline alerts keep every bid on time
  • CSI-guided entry ensures clarity of coverage
  • Polished branded proposals are delivered in one tap as a PDF

Why SubPro

What sets us apart

📋

CSI-Structured Proposals

Every proposal follows CSI MasterFormat spec divisions – this industry standard construction contractors and clients work with. No more freeform proposals that may miss important information from bid to bid. Proposals arrive ready to evaluate.

📅

Bid Calendar & Deadline Alerts

Track every bid by due date via the bid calendar. SubPro sends deadline alerts from your inputs on the bid calendar ensuring you never miss a bid date – timely responses keep you competitive.

📄

Professional PDF Delivery

Generate a polished, branded PDF proposal and send it directly to the client from the app. One tap – your bid is in their inbox.

AI-Powered Workflows (Elite)
