How to Build a Delivery App (Customer, Driver and Dispatch)

The three surfaces every delivery app needs

A delivery business runs on three different screens. The customer needs to order, pay and watch the driver approach. The driver needs a route, stop details, navigation and a way to prove the drop happened. Dispatch needs to see every order and every driver at once and fix problems as they happen. Tepia scopes all three from the start because leaving one out means somebody runs it on text messages.

The customer app is usually iOS and Android, built in React Native or Flutter. The driver app is also mobile, with heavier use of GPS, camera and background location. The dispatch portal is a web app in React that runs on a large screen in the office. All three share one backend on AWS, Azure or GCP.

Tepia built MNC Go for Mother’s Nutritional Center, a grocery ordering app that streamlined orders for a grocery chain. The same architecture applies to restaurant delivery, pharmacy runs, parts delivery and route based services like laundry or propane.

Nine steps to build a delivery app

1. Define the delivery model. On demand (order now, deliver in under an hour), scheduled windows, or fixed routes. Tepia’s Discovery phase settles this first because it changes routing, driver scheduling and the customer experience.
2. Interview drivers, dispatchers and customers. Tepia’s Interview Summary captures the handoffs that fail today: wrong addresses, missed gate codes, cash on delivery, returns. These become User Stories.
3. Review existing systems. Your POS, ecommerce store (Shopify or custom), inventory, accounting and telephony. The third party integration review documents which system is the source of truth for orders and products.
4. Design the customer ordering flow. Catalog, cart, address validation, delivery window selection, checkout through Stripe or Square, order status and live tracking. Tepia wireframes and tests this with real customers before build.
5. Design the driver app around the stop. Today’s route, next stop, navigation handoff, customer contact, item checklist, proof of delivery, exceptions (not home, refused, damaged). Large buttons, offline tolerance, battery awareness.
6. Build routing and live tracking. Stop sequencing, ETAs, driver location updates and a live map shared with dispatch and, in a lighter form, with customers.
7. Build proof of delivery and exceptions. Photo, signature, geotag, timestamp and optional PIN. Exceptions trigger dispatch alerts and customer notifications through push and Twilio SMS.
8. Build the dispatch portal. Order board, driver assignment, route editing, exception queue, customer communication and end of day reconciliation.
9. Pilot, train and roll out. Alpha with two drivers on one route, Beta across a zone, then full rollout with hands on training and Tepia support reps on the first days.

Feature matrix for customer, driver and dispatch

The table below is the feature set Tepia uses to scope a delivery build. The MVP column reflects what closes the order to delivery loop; the rest is phased.

How Tepia approaches delivery app development

Tepia runs every delivery project through its six phase process. Discovery typically takes 1 to 3 months and includes a system investigation of your order sources, user interviews with drivers, dispatchers and customers, and a third party integration review. You receive an Investigation Summary, an Interview Summary and User Stories for all three surfaces.

Design includes a design questionnaire, moodboards, a style guide, detailed wireframes for the ordering flow, the driver stop screen and the dispatch board, and sample designs. Development and Testing runs Alpha and Beta schedules with test plans that include GPS accuracy, background location behavior, functional testing, user acceptance on real routes and non functional testing for battery and data use.

Training is hands on with drivers and dispatchers using user story scenarios like a refused delivery or a reroute. Launch includes data migration of customers, addresses and products, transition from the old process and Tepia support reps on the rollout. See tepia.co/process.

Technical decisions that matter for delivery apps

Background location is the hardest technical piece. iOS and Android both restrict it, and App Store and Google Play review will reject an app that collects location without a clear purpose string and a visible indicator. Tepia has shipped apps through both review processes and designs the permission flow to pass on the first submission.

Routing can start with a simple stop order set by dispatch and move to automated sequencing using a mapping provider’s APIs in phase two. Proof of delivery photos should upload in the background with retry so a dead zone does not block the next stop. Payments run through Stripe or Square with tokenized cards and in app tips, which keeps PCI DSS scope small.

Tepia recommends an offline first driver app, PostgreSQL for orders and routes, Firebase or native push for notifications and Twilio for SMS. Engineers who have built these pieces before are hand picked for each engagement and work in US overlapping hours.
