Protz – Logistics app: On-demand towing and water delivery for Ghana

BACKGROUND & CONTEXT

  • When a car breaks down or the tank runs dry, Ghanaians call whoever they know. There is no way to compare providers, see a price or follow the truck.
  • Towing operators and water-tanker owners run on phone calls and cash, with no tools for requests, earnings or proof that they are legitimate.
  • The two services look different but share the same shape: a request, a matched truck, a trip and a payment.

TARGET USERS

  • Drivers with a breakdown: stressed and on the roadside, deciding on speed and price

  • Households, events and builders: ordering water by the gallon, deciding on quantity, time and access

  • Towing and water providers: deciding whether a job is worth it, and needing to look trustworthy

THE GOAL

Turn two informal services into one trustworthy app: request, match, track and pay for a truck, and give providers the tools to run their business.

MY PROCESS

  1. Domain research
  2. Service mapping (tow vs water)
  3. User flows
  4. Wireframes
  5. UI & components
  6. Prototype

KEY DECISIONS

  1. One app, two services: a Towing | Water switch at the top of home, not two separate apps
  2. Each service asks only what it needs: vehicle, urgency and photos for a tow; gallons, time and access notes for water
  3. Matching on a map with the arrival time, price and 'Find another truck' in one sheet
  4. Pay the way Ghana pays: Protz Wallet with PIN, Mobile Money by USSD prompt, or cash on delivery
  5. Trust on both sides: provider document checks, two-factor sign-in, an emergency contact tile

THE SOLUTION

  • Request: switch service, set pickup and destination, then describe the job in one short form.
  • Match and pay: pick a provider by price and arrival time, then pay by wallet, Mobile Money or cash.
  • Track: a map with a two-step progress bar, the provider's name and one-tap call and chat.
  • Providers: a three-step sign-up (account, then licence, registration and vehicle photos, then a wallet PIN), request pop-ups with the payout, earnings and withdrawals.

KEY FEATURES

  1. Towing | Water service switch
  2. Service-specific request forms
  3. Map-based provider matching
  4. Wallet, MoMo & cash checkout
  5. Provider verification & earnings
  6. Achievements & ratings

DESIGN SYSTEM & ACCESSIBILITY

  • Shared component library across both roles and both services: order cards, payment cards, status bars and chat.
  • Teal #086788 passes AA on white and on the ice-blue tint; status is always shown as text as well as colour.
  • Next round: green prices (#009F22) and grey captions fall below 4.5:1 for small text, and header icon buttons are 40 px, under the 44 px target.

Reused

OUTCOME

  • A complete, prototype-ready marketplace: onboarding, two request flows, matching, payment, tracking, rating and provider payouts.
  • Achievements give both sides a reason to come back: 'Transporter' for 10 tows, 'Workaholic' for 20 deliveries.
  • Its wallet, payment and tracking patterns carried into the later Yenko delivery app.

What I learned

Two-sided products live or die on the weaker side: the provider app needed as much design time as the customer one.
