Project Overview

// section.overview

01

A complete digital transformation for auto service centers

Milani Oil Change Management System was designed to replace the fragmented, manual workflows that plague independent auto service centers. Technicians were recording services on paper, reminders were missed, and customer history was practically untrackable. The goal was to deliver a modern, intuitive web application that consolidates service recording, customer management, automated reminders, and business analytics — all in one place.

Project Problem

// section.problem

02

Manual processes were costing time, money, and customers

Independent oil change centers in Iran operate with little-to-no digital infrastructure. Each visit relies on paper forms, verbal communication, and the technician's memory. This results in lost revenue, poor customer experience, and zero business intelligence.
Service records written by hand — illegible, easy to lose
No unified customer database or vehicle history
Oil change reminders sent manually or not at all
Staff scheduling was done via phone calls and spreadsheets
Zero insight into business performance or customer retention

Stakeholder Needs

// section.stakeholder.needs

03
What vehicle owners actually want
Through discovery interviews with 6 service center owners, four critical need areas emerged.

Customer & Vehicle Management

A searchable database of all customers with their vehicles, contact details, and service preferences — accessible in seconds.

Service History

Full timestamped log of every service performed, with oil brand, filter type, mileage, and technician notes.

Staff Management

Assign technicians to services, track their workload, and manage shifts without phone calls or paper rosters.

Marketing Tools

Segment customers by last visit date or oil type and send targeted SMS reminders to bring them back.

04
What vehicle owners actually want
Surveying 40 vehicle owners revealed clear expectations that no center was currently meeting.
Automatic oil change reminders via SMS before the next service is due
A clear, readable history of all past services and what was done
Memory of preferred oil brand and type — no re-explaining every visit
Estimated cost and time transparency before the service begins
Digital receipt or service summary after each visit

The Solution

// section.solution

06
Four feature pillars that transformed daily operations

Build Fast & Scalable Interfaces

[01]

Log a complete service — vehicle, oil type, filter, mileage, technician — in under 45 seconds. Smart autofill pre-populates returning customers' data.

Smart Reminder System

[02]

Automated SMS reminders sent at configurable intervals before the next oil change is due. Customizable per customer and vehicle type.

Vehicle Service Timeline

[03]

A chronological, visual timeline of every service per vehicle. Technicians see the full picture instantly — no digging through paper archives.

Customer Segmentation & SMS

[04]

Segment customers by last visit, oil brand, or location and run targeted marketing campaigns directly from the dashboard.

Key Screens

Learning & Reflections

// section.learning.reflections

08
01

Context-first research pays off

Spending two full days in actual service centers before writing a single user story completely changed my initial assumptions about what technicians needed.

02

Speed Is the Core Value Proposition

Spending two full days in actual service centers before writing a single user story completely changed my initial assumptions about what technicians needed.

03

SMS over app notifications

Most vehicle owners in Iran don't download apps for a single service center. SMS reminders had dramatically higher reach and response rates than any in-app notification ever could. Designing for the right channel matters more than designing the notification itself.

04

Localization is not translation

Adapting the system for Iranian auto service culture meant rethinking vehicle databases, oil brand selections, and calendar systems — far more than just translating the UI.
