I run a medium-sized construction company in Oman and we have outgrown spreadsheets and stand-alone tools. I now need a fully integrated ERP that mirrors the way we actually work, not the other way around. The platform itself is still open for discussion—web, desktop, mobile, or a smart blend—so feel free to recommend the architecture and tech stack you believe will keep performance smooth in a dusty on-site environment and still be easy to maintain from head office. Scope of work Your brief is to design, develop, test and deploy a modular system that covers every major department: • Project & Site Management • Procurement & Material Management • Inventory & Warehouse Management • Equipment, Tools & Machinery (Plant) • HR & Payroll for both labour and staff • Finance, Accounts & Cost Control • CRM & Sales Each module needs the flexibility for medium-level customisation. We know our workflows will evolve, so clean code, clear documentation and configurable settings are essential. Baseline expectations – Role-based access that lets us separate head-office, site and subcontractor permissions – Straightforward dashboards with drill-down reports (cost vs. budget, inventory ageing, equipment utilisation, etc.) – Seamless hand-offs between modules so, for example, a site engineer’s material request instantly shows up for procurement and stock checks – API or other integration method so we can eventually plug in external accounting or BIM tools – Training sessions for our core team plus post-launch support Deliverables 1. Functional prototype for review 2. Iterative builds with our feedback folded in 3. Production deployment on our chosen environment 4. Source code, technical documentation and user manuals If this sounds like your wheelhouse, outline the stack you would use, your timeline and how you’d break the project into milestones. I’m keen to get moving as soon as we settle on the approach.
