It's a Friday evening and a family wants a car for the weekend. They ring the rental desk. Is the SUV free from Saturday morning? Someone checks a diary. What does it cost for two days? Someone works it out. Then come the documents — a licence photographed and sent on WhatsApp, an ID to be verified by eye, a deposit discussed over the phone, a booking pencilled in and confirmed with a second call. Multiply that by every enquiry on a busy weekend and the constraint on the business isn't the fleet. It's the phone line.
That was the position at EVM Wheels, part of the EVM Group — a premium self-drive car rental service running sedans, SUVs and hatchbacks across Kerala, serving residents and tourists on both short-term and long-term hire, with a reputation built on vehicle quality, affordability and convenience. Every one of those strengths sat behind a manual booking process that had to be repeated, by a person, for every customer.
Acube built EVM Wheels a fully custom Flutter mobile app on a lightweight backend — one codebase for Android and iOS — covering vehicle browsing, live availability, date and time scheduling, digital KYC, in-app payments and real-time GPS tracking of the vehicle during the rental, with an admin dashboard behind it for the EVM team. The headline result: 70% of bookings are now processed through the mobile app.

A custom Flutter app on a lightweight backend, designed around the actual rental journey — search, book, verify, pay, drive, return — with the admin tooling to run it from the office:
| Capability | What it gives you |
|---|---|
| Flutter app (iOS & Android) | A single codebase for both platforms — faster to market, and a consistent interface and experience for every customer regardless of device |
| Vehicle search & browsing | Customers filter by category, availability and location, so they see what they can actually have rather than a general catalogue |
| Booking & scheduling | Date and time-based rental scheduling against live availability, so a confirmed booking is a real one |
| Digital KYC & document upload | Licence and ID uploaded and verified in-app — compliant onboarding without a WhatsApp trail or a counter queue |
| In-app payments & e-receipts | UPI, credit and debit cards and wallets, with invoices and receipts issued digitally against the booking |
| Real-time GPS tracking | Live vehicle location during the rental period through integrated tracking APIs — for the customer's confidence and the operator's control |
| Push notifications & booking history | Pickup reminders, return reminders and promotions, plus past bookings, invoice downloads and feedback forms in the customer's own hands |
| Admin dashboard | Booking management, vehicle assignment, payment reconciliation, customer profile review and manual overrides for the team at the desk |
| Automated reporting | Daily and monthly reports on bookings, revenue and vehicle usage — utilisation you can see rather than estimate |
| App store deployment & support | Published on Google Play and the Apple App Store, with version management and regular feature upgrades |

it was built to support future B2B or subscription rental models without a rebuild. The underlying shift: the booking record is now created by the customer, at the moment of the decision, complete with documents and payment — and everything the office does afterwards is a consequence of that record rather than a reconstruction of it.
We didn't start with screens. We started with the rental counter: what a customer asks first, what actually decides whether the car is available, which documents the law requires before the keys change hands, and where the money moves. Only then did we design the flow and build it.
Two decisions carried the project. The first was Flutter from the outset — one codebase for Android and iOS meant the app reached both sets of customers at once, with the same interface and no second build cycle to fund. The second was designing KYC and payment as part of the booking flow rather than as steps after it; a rental app that sends a customer elsewhere to verify a licence or settle a bill is an app that loses them between screens.
And we didn't leave at launch. App store deployment, version management and regular feature upgrades are part of the engagement — because a live consumer app on two platforms needs someone maintaining it. That is the same long-term support practice we run for every client: in business since 2011, with 70% of our work coming by referral.

At EVM Wheels it took 70% of them. The condition is that the app has to complete the whole job — search, live availability, scheduling, KYC, payment and receipt — because a customer sent back to the phone for any one of those steps will make the whole booking by phone.
One codebase serves both platforms, which means a faster route to market, a single set of features to maintain, and a consistent interface for every customer. For a consumer-facing rental app where the audience is split across both platforms, it removes the choice between reaching half your customers and paying for two builds.
Customers upload their licence and ID inside the app during booking, and the documents go through verification before the rental is confirmed. It keeps onboarding compliant and auditable, and it moves the document check off the counter and out of the queue.
Yes. Real-time GPS tracking runs through integrated tracking APIs for the duration of the rental, so the location of an active vehicle is visible rather than assumed. It supports both the customer's confidence and the operator's control over the fleet.
UPI, credit and debit cards and wallets, with e-receipts and downloadable invoices issued against each booking. Payment reconciliation is handled in the admin dashboard, so what was collected and what was booked stay tied to the same record.
No. The build starts from the rental journey, not from fleet size, and the backend was designed to scale — EVM Wheels' architecture was built to take future B2B or subscription models. You can start with booking and payments, prove it, and add tracking, reporting or new rental models as you grow.
