I need a shared scheduling system that mirrors the look and feel of our current Aroflo calendar while giving each of our six subcontractors a private login. When a trade logs in—whether from a browser in the office or the mobile app on-site—they should see only their own jobs for the day, week, or month. At the same time, my admin team must be able to open a single screen and view all six calendars side-by-side so we can quickly match new bookings to the right person. Core expectations • The calendar must work seamlessly on both web and mobile, keeping the interface identical to Aroflo’s layout. • Secure logins for six individual users plus an admin role that aggregates every schedule. • Built-in notifications and reminders (push, email, or SMS—whichever you recommend) so no one misses a booking. • Customisable calendar views—day, week, month, agenda—toggled instantly without losing the Aroflo styling. Please send a detailed project proposal that outlines your recommended tech stack, timeline, milestone breakdown, and how you will handle data security and ongoing support.
