1. Project Overview
Apptixx Pty Ltd is developing a modular, enterprise‑grade platform designed for the construction, design, and real estate sectors.
This project represents Phase 1 — the creation of a core client portal that will act as the central hub for all future modules.
The platform must be built with scalability, modularity, and multi‑tenant capability in mind, as future modules (quoting, contracts, compliance, payments, AI tools, etc.) will be integrated into this core.
2. Objective of Phase 1

Documents
Stakeholders involved
Timeline view
B. Design Project Tracking
Clients can view:
Concept → Drafting → Revisions → Approvals
Status updates
Document hub
Comments/notes

Appraisal → Listing → Marketing → Offers → Contract → Settlement
Status updates
Document hub
Agent notes (read‑only)
