SOCAR – Mobile Application for a Leading Fuel Trader

case-logo

SOCAR Ukraine is one of the country's leading fuel traders, with a wide network of modern gas stations, and it wanted to make buying fuel and other goods faster and more convenient for its customers.

Our team developed a cross-platform mobile app for iOS and Android with QR-based ordering and cashless payment. Customers can now order and pay for fuel or coffee straight from the car, and receive a digital receipt in the app or by e-mail.

About the company

SOCAR Ukraine operates a network of modern fuel stations that offer quality fuel as well as coffee and snacks.

The company aims to lead innovation in Ukrainian fuel retail and to improve customer convenience and satisfaction through technology.

Project goal

About the project

The owners wanted to give customers an app with everything needed to make buying at SOCAR stations comfortable and smooth. 

The main goal was a cross-platform app that combines QR code scanning with a cashless payment system, so customers can refuel with just a smartphone, with no cash or physical bank card.

Challenges

1

A Multifunctional App for Two Platforms

One app for Android and iOS that handles fuel, coffee, and other purchases with a consistent experience on every device.

2

Cashless Payments with Existing Infrastructure

A secure payment system that works with the stations’ payment systems and cash registers, so receipts are printed remotely and delivered electronically.

3

Ordering from the Car

QR scanning at fuel pumps and coffee machines, so customers can order quickly without leaving the car.

4

A Simple, Pleasant Interface

A modern, intuitive UX that reduces steps in the purchase process and boosts customer satisfaction and loyalty.

5

Reliable Real-Time Operation

Instant recognition of the product, payment, and receipt, with every system staying in sync at each station.

Our process for the Mobile Application

We studied user needs and SOCAR’s service flow to define key features and user journeys, focusing on minimizing steps in the purchase process.

We designed an interface focused on speed and simplicity, so a customer can order fuel or coffee in a few taps.

We built the app for Android (Java) and iOS (Swift) and added Google APIs for location-based features such as station search and navigation.

We implemented QR scanning at pumps and coffee machines using WebSockets, RabbitMQ, and Redis, so the app recognizes the product type and processes the order immediately.

Using Python, Django, Celery, and Redis, we built a secure cashless payment system. Once the amount is confirmed, the system charges the funds and remotely prints a receipt.

We ran comprehensive manual testing, including functional, non-functional, regression, and smoke tests, before releasing the app.

Key features

Cross-Platform Mobile App

Native apps for Android and iOS with smooth performance and a consistent experience.

QR Code Ordering

Scan the code on a pump or coffee machine, choose liters or an amount, and the system identifies the product and processes the order.

Cashless Payment

Instant, card-free payment through secure payment APIs, with funds charged as soon as the amount is chosen.

Remote Receipts

Fiscal receipts are printed remotely, then stored and available in the app or by e-mail.

Smart Coffee Machines

The app identifies the coffee type from the QR code, takes payment, and sends the command to the machine without staff involvement.

Fuel Ordering from the Car

Choose the fuel amount in the app, and a station employee starts refueling once the system identifies the fuel type.

Station Search & Navigation

Google APIs help users find nearby SOCAR stations and navigate to them.

Analytics Dashboard

QR usage data shows campaign effectiveness, service popularity, and customer behavior.

Other Purchases at the Station

Users can order coffee and other goods through the app, with room to add more product categories.

“We offer custom menswear with online and offline showrooms in Singapore and the UK. People sign up online, come into the showroom, and are measured. We then have their measurement profiles so they can go and reorder online when necessary.

Initially, we had a booking tool that was relatively basic. Together with Soloway, we overhauled the booking tool, making it a lot more flexible and useful to our needs. In the end, we started with the development of an entire order management system that administers measurements and tracks orders along the process. Soloway’s streamlining of the booking system nearly eliminated customer service calls, reducing staffing needs. Their intuitive project management system allowed for an easy flow of information. Soloway was an honest and transparent development partner.”
