Sample business app: BuildFlow Contractor Project Tracker (fictional records, not a client project). A simple project tracker built by KTW AdVentures to show what a custom business app can look like. You can add projects, move each one through Lead, Estimated, In Progress and Completed, filter by status, and see running totals. This is a small demo with sample data; a custom app for your business is built around your own jobs, quotes, invoices or bookings. Tools used: HTML, CSS and JavaScript.
