I want to digitise our on-site operations with a single solution that runs smoothly on both iOS and Android. The app will clock workers in and out through GPS-based geo-fencing, snap an automatic selfie for verification, and tag the entry to the exact site. On the back end those punches must drive payroll—regular hours, overtime, and leave calculations—so salaries are produced at the click of a button. Inventory is the next pillar. I need real-time inward and outward material movements tied to each project site, plus a simple requisition flow where staff raise a request and a manager signs it off before stocks are dispatched. An online admin panel should tie everything together with intuitive dashboards and exportable reports so I can see labour costs, stock levels, and pending approvals at a glance. User roles that must be available: • Employee • Manager/Supervisor Please share links to any ERP, workforce, or logistics apps you have built, suggest a tech stack and scalable architecture, and outline an estimated timeline and cost. Gurugram-based teams are preferred, though I am open to remote collaboration if you can demonstrate relevant experience.
