Construction Expense & Ledger Platform

I’m building a unified cost-control and digital site ledger that works seamlessly on both web browsers and native iOS/Android apps. The core of the system is an expense module capable of smart categorisation, photo or PDF receipt uploads straight from the field, and one-click generation of automated daily, weekly, and month-end reports.

The interface has to be practical for busy construction teams, so I’d like clean dashboards, offline capture that syncs when a signal returns, and fast search/filter tools to locate any transaction or note in seconds. While I will fine-tune the permission matrix later, please structure the code so multiple roles—think project managers, supervisors, accountants and any others we add—can be assigned granular access rights without rewriting logic.

Tech stack is your call; just ensure it’s scalable and pairs nicely with a SQL or NoSQL back-end and well-documented REST/GraphQL APIs, so future integrations with ERP or payroll are straightforward.

Deliverables
• Responsive web app and companion iOS/Android builds (store-ready or via Expo/equivalent)
• Expense module with categorisation, receipt capture, and automated reporting as described
• Role-based access control scaffold
• Source code in a Git repo with setup docs and a short video walkthrough

Once the MVP passes a quick hands-on review on my test devices, we’ll discuss phase-two features like budget forecasting and supplier portals.
