Our Work / Food Delivery App

Food Delivery App

A food delivery service taken from concept to working app, connecting hungry customers, local restaurants and the drivers between them.

Business goals

The client had an idea for a food delivery service and needed to turn it into something people could order from. Delivery is unforgiving: food goes cold, restaurants get busy and customers watch the clock. Before writing code, the client had to settle how the service would work for each party. It then needed an application that could coordinate restaurants, drivers and customers on every order.

Project overview

Hexagon started with concept development, working through how orders, restaurants and deliveries should fit together. We then built the app and supporting application. Customers browse menus, order, pay and follow their delivery. Restaurants receive and confirm orders on their own screen. Drivers accept and complete deliveries from a dedicated app. An admin application lets the client's team manage partners, menus and live orders.

Challenges faced and solved

A delivery order has a short life, and three different parties can each ruin it.

The challenge

An idea with too many moving parts

A delivery concept sounds simple until you ask who confirms the order, who sets prep time and who handles a missing item. Unanswered, those questions become expensive rework during development.

Our solution

We began with concept development, mapping each order from start to finish, so decisions about roles and exceptions were settled before the build began.

The challenge

Restaurants miss orders during a rush

At Friday dinner, a kitchen is juggling dine-in tables and phones. If a new delivery ticket goes unnoticed, the customer waits, the driver stands around and everyone blames the app.

Our solution

We gave restaurants a dedicated order screen with an audible alert and a simple accept step, plus a prep time estimate that drivers and customers can see.

The challenge

Drivers arriving at the wrong moment

If a driver shows up too early, they wait and earn less. Too late, and the food sits under a heat lamp going soggy. Timing is the difference between a repeat customer and a refund.

Our solution

We tied driver dispatch to the restaurant's order status, so assignments follow the kitchen's progress and pickup details are clear before the driver sets off.

The challenge

Customers left wondering where dinner is

Few things produce more support tickets than an order with no visible status. Hungry customers assume the worst after a few silent minutes and start contacting whoever they can reach.

Our solution

We show order status at each stage, with live map tracking once the driver is on the way and push notifications for each change.

Features

FeatureDescription
Customers
1. Account and Saved AddressesCustomers save delivery addresses, so repeat orders take only a few taps.
2. Restaurant DiscoveryNearby restaurants are listed based on the delivery address, with search and cuisine filters.
3. Menus and Item OptionsEach dish can carry options such as size, extras and special instructions, so the kitchen gets the order right.
4. Cart and CheckoutCustomers review items, delivery details and total before paying in the app.
5. In-App PaymentsPayment happens inside the app, so the driver doesn't have to handle money at the door.
6. Live Order TrackingStatus updates and a map show progress, which reduces anxious calls to support.
7. ReorderA past order can be repeated quickly, which suits the weeknight regular.
8. Ratings and FeedbackCustomers rate the food and the delivery separately, so problems reach the right party.
Restaurants
9. Order ScreenNew orders arrive on a dedicated screen with an alert, keeping them out of the phone queue.
10. Accept and Prep TimeStaff accept an order and set a prep estimate, which drives what the customer and driver see.
11. Menu ManagementRestaurants edit items and prices, and mark a dish as sold out before someone orders it.
12. Opening Hours and PauseA kitchen can pause new orders during a rush, which protects quality when it's overloaded.
Drivers
13. Driver Sign-UpNew drivers register and submit their details for approval, keeping the fleet vetted.
14. Availability ToggleDrivers go online and offline as they choose, so offers only go to people ready to work.
15. Delivery OffersAvailable jobs show the pickup and drop-off before the driver accepts.
16. Navigation Hand-OffDirections open from the job screen, reducing wrong turns on the way to the customer.
17. Proof of DeliveryDrivers mark orders as delivered, closing the job and telling the customer it has arrived.
18. Earnings ViewDrivers see completed trips and earnings, which helps retain them.
Client team
19. Partner ManagementStaff onboard restaurants and approve drivers from one application.
20. Live Order BoardAll active orders show in one view, so staff can step in when one is running late.
21. Refunds and IssuesSupport staff handle missing items and refunds against the order record.
22. Delivery Zones and FeesStaff define service areas and delivery fees, so the service can expand one neighborhood at a time.

How we took it from idea to launch

Good software follows a process. Here are the six stages, and what happens in each one.

Stage 1

Discovery & Requirements

Goal: Define the product vision, target audience and core business requirements.

Key activities
  • Stakeholder interviews
  • Market and competitor research
  • Defining user personas
  • Drafting technical specifications or a Product Requirements Document (PRD)
Stage 2

Design (UX / UI)

Goal: Create an intuitive user experience and visual interface.

Key activities
  • UX design: information architecture, user flows and wireframes
  • UI design: high-fidelity mockups and interactive prototypes in Figma or similar tools
  • Design system: colors, typography and component libraries
Stage 3

Development: Frontend & Backend

Goal: Build the functional application using agile sprints.

Key activities
  • Backend: set up databases, design APIs (REST, GraphQL), implement server logic, and configure authentication and authorization (OAuth, RBAC)
  • Frontend: build responsive interfaces and connect components to backend APIs
  • Version control: manage code through Git and GitHub
Stage 4

Security & Optimization

Goal: Harden the application against vulnerabilities and boost performance.

Key activities
  • Security: address the OWASP Top 10, including injection, XSS and CSRF, enforce encryption in transit and at rest, and implement rate limiting
  • Optimization: code splitting and lazy loading, database indexing, API caching and load testing
  • QA and testing: unit, integration and end-to-end tests
Stage 5

Beta Release

Goal: Deploy to a controlled group of real users to catch edge-case bugs and gather feedback.

Key activities
  • Set up staging and production CI/CD pipelines
  • Launch a closed or open beta with real users
  • Monitor errors through observability tools
Stage 6

Public Release (Launch)

Goal: Roll the software out to the general public.

Key activities
  • Final production deployment
  • DNS configuration
  • Marketing and onboarding rollout
  • Post-launch performance and security monitoring

Business benefits

Less rework

Settling the operating model first meant fewer surprises during the build.

Fewer support contacts

Clear status and tracking answer the most common customer question.

Happier restaurant partners

Orders arrive in one place, separate from the phone and dining room.

Room to expand

Zones and fees can be set per area as the service grows.

Conclusion

Food delivery looks like an app, but it is really a timing problem shared by a kitchen, a driver and a hungry customer. Hexagon helped the client think that through during concept development, then built the tools each party needed to do their part. Starting with the concept meant the software reflected real operating decisions, not guesses. If you have a delivery or ordering idea and you're not sure how all the pieces fit together, talk to us. That conversation is a good place to begin.

FAQs

I only have an idea. Is that enough to start?Yes. This project began at the concept stage, before any requirements were written.
Do I need separate apps for customers and drivers?Usually, yes. The two jobs are different, and each screen stays simpler when separated.
How do restaurants receive orders?On this project, they use a dedicated order screen with an alert, and they accept each order and give a prep time.
Can the service launch in one area first?Yes. Delivery zones let you begin with a small area and add more as you're ready.
