Challenge

The problem we walked into.

A rental counter's worst day is a double booking: two customers, one bike, and a deposit already taken from both. It happens because availability is tracked in a notebook and confirmed over WhatsApp. Meanwhile the staff member doing it is standing at a counter, on a phone, on a connection that comes and goes.

Approach

How we framed it.

One source of truth for whether a vehicle is free — if the system says available, it is available, with no second opinion anywhere in the product. Everything else was designed thumb-first for a phone: the walk-in flow beats feature breadth, and every screen has to survive a bad connection.

Solution

What we shipped.

A rental business in one app: vehicles, availability, bookings by the hour through to the month, deposits and advances, handover records with photos, and running totals of what each customer still owes — plus a public page where customers can see the fleet and enquire.

Features
  • Availability that is never double-booked, from one source of truth
  • Rent by hour, half-day, day, week, month or a custom period, priced automatically
  • Deposits, advances, dues and overdue tracking across cash and mobile money
  • Handover records with photos, so damage disputes have evidence
  • A public page per company, and a staff app that works on a slow connection
