Why Your eCommerce Store Needs a Mobile App Alongside Your Website

Your eCommerce website already allow customers browse products, place orders, make payments, and track purchases. So why build a mobile app?

For many stores, there is no good reason to replace the website. The stronger case is to add a mobile app for customers who already know and buy from your brand.

What’s different about using a mobile app is how customers come back to purchase, how directly you can contact them, and how much of the shopping journey can continue from where they left off.

Studies have been conducted on retailers who developed apps despite the existence of mobile websites. They showed that app users later purchased more often and made larger orders.

So when does adding an app actually make sense?

When the customer has to keep finding your store repeatedly

A website works when the customer comes to it.

And in most cases, this may be sufficient for one-time purchases by customers attracted through Google search, social networks, advertisements, and saved web bookmarks.

Imagine a customer who bought from your store last month and wishes to buy again.

With a website

Think about your store → open a browser → search for or type your store URL → open your website → log in or go back to the product → proceed with browsing.

All these actions are not complicated. However, each one adds another reason for the customer to get off track.

With an app

The store already has its place on the customer’s phone:

Open app → browse or continue shopping → buy.

This does not mean an app is automatically better. First, the customer should download the app and decide to use it. Therefore, an app is suitable for companies that have enough repeat business opportunities for this extra adoption step.

When you want to bring customers back instead of waiting for them

This is probably the clearest difference between a website and an app.

A website is primarily something a customer visits.

But a mobile app can become another channel for communication with the customer via the store.

Think of a limited-time promotion.

Website workflow

The merchant launches the sale.

Now the customer has to encounter it through:

• Email

• Search

• Social media

• Paid advertising

• Another visit to the website

If the customer does not see the campaign, the website cannot simply appear on their phone and remind them.

App workflow

The customer has already installed the mobile app and has also agreed to receive notifications from the merchant.

The merchant conducts a campaign → sends out a push notification → it is received by the customer → he clicks on it → lands in the app → continues shopping.

This represents a completely new communication loop.

Mobile app solutions for PrestaShop and OpenCart support manual push notifications, allowing merchants to send messages to app users from the store backend.

The advantage is not “push notifications are better than email.” The advantage is having another direct re-engagement channel that a normal responsive website does not provide by itself.

Abandoned carts show the difference even more clearly.

Suppose a customer adds ₹3,000 worth of products to the cart and leaves.

You already know this customer was interested enough to add the products. The question is how easily you can bring them back.

On a website

The customer leaves the site.

You can use email, advertising, or other remarketing methods to reach them. But those methods operate outside the shopping session. The customer has to notice the message, return to the website, and continue from there.

On a mobile app

The customer leaves the app.

An automated abandoned-cart notification can be triggered after a configured interval. The customer taps the notification and returns to the app.

Customer adds products → leaves → notification is triggered → customer taps → returns to the cart.

The PrestaShop Mobile App builder supports automated abandoned-cart push notifications with a configurable time interval.

The same principle is documented for its OpenCart mobile app solution.

This is a good example of where the app is not replacing something the website already does. It is closing the gap between customer intent and the customer's next visit.

Order updates are another practical use case.

A website can obviously show order status.

The difference is how the customer finds out that something has changed.

Website

Order shipped → customer needs to open the website → log in or find the order → check the latest status.

App

Order status changes → notification is sent → customer taps → order information opens.

For PrestaShop and OpenCart store owners, OpenCart mobile app and PrestaShop mobile app support notifications for successful orders and order-status changes, including delivery updates.

Again, the website is not incapable of showing the information.

The app simply creates a proactive notification-to-information workflow instead of making the customer repeatedly check.

That distinction becomes more valuable for stores with frequent orders, delivery updates, or repeat customers.

A mobile app can remember the relationship, not just the website session

A browser session is usually about the current visit.

An app can become a customer's regular shopping destination.

Think about a customer who has:

• Previous orders

• A wishlist

• Products they regularly purchase

• Their account

• Their cart

• Familiar navigation

• A reason to receive store notifications

The customer is no longer starting from the website homepage every time.

For example:

First purchase: Customer discovers the store through Google.
Second purchase: Customer receives a relevant notification and opens the app.
Third purchase: Customer opens the app directly because it is already the familiar place to shop.

That is the longer-term value an app can create.

Do not build an app just because you have a website

This is important.

If most of your customers are those who buy once and never come back, having a mobile app might be irrelevant.

Similarly, if your customers come to your store for the very first time through Google also have no need for an app at all.

The stronger case exists when your store has:

• Regular repeat purchases

• A meaningful base of existing customers

• Abandoned carts worth recovering

• Frequent promotions

• Customers who benefit from order updates

• Products that encourage customers to return

• Enough customer loyalty to justify app installation

Research also suggests that app adoption can have a stronger effect among less-loyal customers, meaning the mobile app for PrestaShop and OpenCart can potentially help strengthen relationships with customers who have not yet become regular buyers.

Website + Mobile App is the stronger model

The choice does not have to be:

Website OR app.

For many eCommerce businesses, the better model is:

Website → acquisition and discovery
App → retention and repeat engagement

A customer could come to your store for the first time via Google and make the first purchase on your website.

After this, there is an option to get them to install your app.

The next journey could look like:

Google → Website → First Purchase → App Installation → Push Notification → Repeat Visit → Second Purchase → Order Updates → Reorder

The website continues doing what it does well: bringing new customers in.

The app adds another layer for customers who have already shown enough interest in your brand to stay connected.

How PrestaShop and OpenCart stores can use this model

For merchants running PrestaShop or OpenCart, the goal should not be to build a second store and maintain everything twice.

The practical approach is to connect the mobile shopping experience with the existing store.
PrestaShop Mobile App Builder and OpenCart Mobile App Builder are designed around this model, with synchronization between the existing store and the mobile app, while supporting shopping, checkout, order-related communication, and push notifications.

That makes the decision easier to evaluate.

You are not asking:

“Can my website already do this?”

Most likely, the answer will be yes.

Instead, ask:

“Do I want customers to keep coming back to my website, or do I want to give my most valuable customers a dedicated place to return to, and a direct way to bring them back?”

If your store depends on repeat purchases and ongoing customer relationships, that is where the eCommerce Mobile App by Knowband starts making a real business case.
