Ecommerce Mobile App Development

Alpha ExpansionE-commerce
In short

An ecommerce mobile app gives your returning customers a faster way to buy from the store you already run. It shares the catalogue, prices, stock, basket and accounts with your website, and adds what only an app can: staying signed in, payment with a glance, notifications the customer chose, quick reordering and a loyalty card. It is built as a new front end to your existing store, with nothing kept twice.

Key points
  • 01The app reads your existing store, so prices, stock and orders are never kept twice.
  • 02It is built for returning customers: signed in, saved payment, quick reorder.
  • 03Marketing changes banners and offers without waiting for an app release.

The main workflow, step by step

The window follows a returning customer from a notification to a delivered order, and the retailer's team behind it. Choose a step to see its screen. The retailer, the customer and the products shown are invented for the demonstration.

Who uses it, and what each role can do

An app adds a channel, not a second shop. The roles are the same people who run the store, with tools to manage what the app shows.

03

When the work leaves the usual path

The app depends on the store, the payment provider and the customer's phone. These are the points where one of them falls short.

What it connects to

Almost everything in the app comes from systems you already operate. What the app can do is set by what those systems expose.

Common questions

Do we need an app if our website already works on phones?

Only if enough of your customers come back often. First-time buyers arrive through search and adverts and land on the website, which should be fast in any case. An app pays for itself with regular customers, through staying signed in, quick reordering and notifications they value. Start by measuring your share of repeat orders.

Will the app work with our current store platform?

In most cases, yes. The common platforms offer interfaces for catalogue, basket, customers and orders, with differences by plan. We confirm what yours provides before design, because it defines what the app can do. Where the platform's own checkout must be used, the app hands over to it at payment and returns afterwards.

Should we build for iPhone and Android together?

If your customers are split between them, launching on both avoids leaving a large group out, and cross-platform frameworks make that practical with one codebase. Your website analytics show the split. Where one platform dominates strongly, starting there and following with the other is a reasonable way to learn first.

How do we get customers to install it?

Offer it at moments when it clearly helps: after a second order, in order emails, on packaging. Give a concrete reason, such as faster reordering or delivery updates. Showing an install banner to every first-time visitor mostly irritates. Measure installs by source and whether those customers go on to order in the app.
