Builders Bid Book - Construction Bid Management SaaS Platform

Builders Bid Book is a scalable construction bid management software platform designed to modernise how contractors, subcontractors, and construction firms manage RFQs, tender submissions, and project collaboration.

This multi-tenant SaaS application replaces fragmented spreadsheets, email chains, and manual tender workflows with a centralised, role-based digital system.

It was built to support high-volume bidding environments where real-time collaboration, document control, and audit ability are critical.

Problem It Solves

Construction bidding workflows are traditionally:

• Email-heavy and error-prone

• Lacking visibility into bid status

• Difficult to track across multiple subcontractors

• Poorly structured for collaboration

• Not audit-friendly

The platform provides a structured tender management system with full life-cycle tracking.
