I need a full-scale, construction-focused ERP that brings every business function under one roof—from the first client enquiry right through to project handover. The solution must be cohesive, web-based, and ready for multi-company, multi-project use with role-based access, real-time dashboards, and tight audit trails. Below are the core modules I expect to see live and fully integrated at go-live: • Enquiry & Pre-Sales • Tendering & Estimation • Contract & Project Setup • Planning & Scheduling • Procurement & Purchase • Inventory & Store Management • Sub-contractor Management • Site Execution & Monitoring • Labour & Workforce Management • Machinery & Equipment • Quality (QA/QC) • Safety & HSE • Finance & Accounts (mission-critical) • Billing & Invoicing • MIS & Management Reports • Document & Drawing Management • Project Closure & Handover Several of these modules will need customisation to match our current workflows, especially Finance & Accounts, Planning, and the Procurement chain. I will provide detailed process maps after we kick off. Key expectations • Single source of truth: one database, seamless data flow between modules • Strong reporting layer with drill-downs and export to Excel/PDF • Responsive UI that works on desktop and tablet for site teams • Source code handover and technical documentation on completion • Phased rollout with clear milestones, unit tests, and user-acceptance testing If you have delivered similar construction ERPs or complex modular systems in .NET, Java, or PHP frameworks (e.g., Laravel, Spring, ASP.NET Core), I’d like to see live demos or references. Let’s discuss your approach, estimated timeline, and how you propose to tackle the customisation pieces.
