Mobile apps for grocery shopping have been growing in popularity for years, but in 2020, this industry’s growth went through the roof. Traditional grocery chains started to develop and improve their grocery software to let customers order food and beverages remotely

Modern grocery apps, however, offer more than just online grocery shopping: they give businesses the opportunity to increase their sales, reach a new market of active mobile users, learn more about their customers, and make highly targeted offers that increase conversion rates and, consequently, revenue.

In this article, we’ll discuss how to start a grocery delivery service by creating a grocery shopping app for your business, whether it’s a small store or a large chain.

To start, let’s analyze the prospects of online grocery app development and see how welcoming the market is for new grocery shopping software.

Grocery shopping mobile apps: market overview

Grocery shopping is a $1.04 trillion market globally, and in 2020, the percentage of online grocery sales grew to 10.2% or $106 billion according to a study by Mercatus. Compare that to $34.4 billion in 2019. The pandemic has massively influenced the market, and according to Mercatus, by 2025, online grocery sales will double compared to 2020.

In this graph, you can compare the pre-COVID and post-COVID market:

In the US, online grocery shopping is expected to grow from 34% of the grocery market at the beginning of 2020 to 55% to 66% in 2024 according to Business Insider Intelligence.

Mobile applications are the primary tool for online grocery shopping. At the beginning of April 2020, global downloads of grocery shopping apps reached 106 million a month. Walmart reported the highest number of downloads ever in April and took first and second places on the Google Play Store and Apple App Store respectively.

Another large player in the online shopping market, Amazon, has reported that its app downloads have increased by 20% since January 2020.

This spark in interest is obvious if you check Google Trends:

But what will happen after the pandemic? Will online grocery sales drop? Even after the COVID-19 pandemic is over, a large number of people will choose online grocery shopping as their primary strategy due to convenience and time savings.

In the US, online sales of food and beverages are projected to grow to $28 billion by 2022 according to eMarketer. With the pandemic, these numbers may be higher.

Types of grocery shopping apps

A grocery purchasing and delivery service requires at least two sides: vendors (suppliers) and customers. Sometimes, there are also couriers. Let’s examine the main types of grocery shopping apps based on who provides these services.

Small stores

Small stores usually create a grocery app to retain their existing customers and improve the in-store experience instead of to attract new customers. Small businesses tend to use out-of-the-box solutions for their mobile apps because of limited budgets and small feature sets that include listings and the ability to order delivery.

Large store chains

Applications for large grocery store networks tend to be feature-rich, offering listings, loyalty programs, online payments and orders, and various delivery options such as store pick-up from store or home delivery. Such applications also have geolocation features that allow customers to find the chain’s stores. Grocery chain apps collect information on purchases and customer locations and can send highly personalized notifications based on that information.

Multiple stores

Aggregator apps work as mediators between stores and buyers, allowing users to choose products from different stores in one place. Apps for aggregator marketplaces usually earn money by charging a fee for each order. In exchange, stores get an online presence and get perks such as marketing and access to a new audience.

Courier apps

Courier apps don’t represent a particular store or group of stores. Instead, they allow users to hire someone who will not only deliver goods from a grocery store but also pick and buy them. Instacart is one of the most popular examples of a courier app, and it’s based on the gig economy, and all its service providers are contractors.

When it comes to types of services, grocery shopping apps can be divided into these categories:

  • Grocery delivery apps
  • Price comparison platforms
  • Shopper list apps
  • Discount apps

In this article, I’ll be talking about creating a custom app for a grocery store or a supermarket. The feature set I’ll describe will be suitable for a chain of supermarkets, and depending on your business goals, you can cherry-pick the features you’ll need for your custom solution.

If you have a small store and you’d like to create a simple software product, there are two options I’d recommend: using an off-the-shelf builder or creating a simple cross-platform app with Flutter.

Benefits of building a custom grocery shopping app

There are hundreds of off-the-shelf grocery shopping app solutions on the market that offer features like payment gateways, listings, and delivery functionality. However, such solutions are hard to customize and scale as your business grows.

An off-the-shelf solution has its benefits, such as instant access, low initial investment, and support. But what can a custom grocery delivery app development offer?

Customization

This is the most obvious benefit of any custom development: the ability to build exactly what you need for your business and scale or change your product in any way you want. Customization allows you to make your app unique and stand out from competitors with simpler and more generic mobile solutions.

With custom development, you can build exactly what you need for your business and scale or change your product in any way you want

When developing a custom application, you’re free from any restrictions. You can choose any design, payment gateway, and functionality.

Speed

A custom mobile app is often higher quality than an off-the-shelf solution because its architecture is designed specifically for your needs and it has no unnecessary parts.

If you want to save money for marketing, you can use cross-platform technologies like Flutter that have great performance. This will make your app work smoothly and let you bring the best service to your customers.

For your customers, speed is one of the biggest advantages of shopping in a mobile app over shopping offline. In a mobile application, customers don’t have to wait in line and carry the products home. A mobile app gives customers the opportunity to do everything online and get products delivered in as little as an hour.

Convenience

Being convenient should be the primary goal of your mobile product. Getting revenue as a result of this convenience should be the primary goal of your business. To make your software as convenient as possible, you need a smart grocery app UX design that will make the user journey as short and smooth as possible.

Custom mobile apps have more opportunities to provide a convenient user experience, as the UX designer can lean on your business goals and your brand when designing the user experience.

Quality and reliability

I’ve already mentioned quality as one of the benefits of a custom mobile app. A custom grocery app that’s developed by an experienced vendor will be more maintainable and perform better than any off-the-shelf solution because the architecture and technologies will suit the particular feature set.

You can never know what’s under the hood of your off-the-shelf app, and this can cause problems in the form of unpredictable downtime that you can’t do anything about.

A custom app is always under your control, as you can test its separate parts and minimize both security and performance risks.

Customer data

A custom grocery app can give you access to data about your customers that you could never attain without the app — data on the devices customers use, the products they buy at your store, their behavior, their habits, and their preferences. You can customize your analytics to your liking and collect data on how customers interact with your business through your app.

You can then use this data to personalize your offers.

Special offers and increased conversions

After you’ve collected data about your customers, you can target particular groups of customers with personalized offers, discounts, and promotions. Using algorithms, you can predict what products your customers are currently interested in, what makes them choose a particular product, and so on.

Personalized offers paired with push notifications can dramatically increase your revenue. Also, you can add loyalty programs to your application and allow customers to collect bonuses for each online order or by scanning an in-app QR code in your offline store.

Now let’s talk about the features you’ll need to make grocery shopping easy for your customers.

Must-have grocery shopping app features

Client application

Personal profiles

A personal profile contains information about a user, including their name and favorite offline store.

Login and onboarding

Your customers should have multiple ways to register and log in to your app. It’s common practice to allow users to log in with an email address, phone number, or social media profile.

Onboarding offers a short tutorial on how to use your app. It’s optional, but it definitely helps users get to know your app and service.

Product listings

If you plan to offer delivery, you should definitely add product listings to your app so users can choose what they want to order. A product listing usually consists of a product name, pictures, and a rating.

Search and filters

To help your users find the products they want, add a search bar. The best practice is to make search predictive so users don’t have to completely type the name of a product.

Category tree

A category tree is another tool to make searching easier for your customers. A category tree allows users to search for products of a certain type without having to type a product name into the search bar.

Voice search

Voice search is a growing trend in ecommerce, with more and more people ordering products online using voice commands. Though it’s not a must-have feature, it can definitely enhance the user experience and make your product competitive.

Loyalty card

Make your service more convenient by adding a loyalty card to your application. Allow your customers to use this loyalty card in your offline stores and when making online orders. Loyalty cards can be displayed as barcodes or QR codes that your staff can scan in your offline store.

Bonuses and promotions

Make sure to show discounted products in your app. We advise you to place this information on the home screen so it’s the first thing your users see when they launch the app.

Favorites

Allow users to add products to their favorites if your product supports ordering products online. You can also notify users when products in their favorites are on sale.

Shopping cart

The shopping cart is the final step in your user’s journey, and it should show the products your user has decided to purchase along with the total price, taking into account all promotions and loyalty card bonuses.

Shopping carts are often abandoned, so we advise you to send automated notifications reminding users to complete their purchases.

Delivery options

Give your users different delivery options. Users might choose to pick up products from your store themselves, or choose home delivery. The delivery price should also be reflected in the shopping cart and at the checkout.

Payment gateway

Choose a payment gateway that has lots of payment options, or integrate several payment gateways, such as Braintree, Stripe, Google Pay, and Apple Pay. There are hundreds of payment gateways. Some are international; others are local and popular in particular countries or regions. Each payment gateway has its own fees and charges, so choose the most beneficial options for you.

Also, don’t forget to add a cash on delivery payment option.

Order history

A user’s order history shows all purchases the user has made in the app or in offline shops after scanning a loyalty card. You can also use information about previous orders to personalize your offers.

Map

Location-based features will be great for finding offline stores, delivering orders, and sending location-based push notifications. There are lots of maps you can integrate and customize to your liking. We usually advise Google Maps or Apple Maps depending on the app’s platform.

Notifications

Push notifications are the primary way to communicate with app users. Send them to promote offers, inform users about new products and discounts, and remind users of abandoned shopping carts.

If you want to connect your offline and online grocery business, you can also implement location-based push notifications

Online support

Let users connect with you and get support with your service. To automate online support, you can integrate a chatbot that can answer generic questions on products, delivery statuses, and so on.

Reviews

If you plan to create a marketplace for grocery stores, it’s vital to add reviews. Even if you’re building an app just for your store, however, you can still add functionality so users can leave reviews.

Along with a grocery shopping app, you’ll need to develop an admin panel where you can control your application and manage your users and in-app content. Let’s see what features you’ll need for a grocery app admin panel.

Admin panel features

User management

An admin should be able to see information about users, including their logins and passwords.

Content management

In the admin panel, you should be able to change content in your app: add new products, edit descriptions, change photos and prices, and so on.

Order management

You should be able to see the current orders, their statuses, and all order details.

Push notifications

In your notification center, you should be able to create and send notifications to all users or particular groups of users. You should also be able to automate push notifications: for example, to send a notification after two days of inactivity.

Payments

You should be able to see all payments your customers make through your app and see the most popular payment methods.

Analytics

Analytics can allow you to learn everything about how your app is performing from both the technical and business perspectives. See how many monthly, weekly, and daily users you have, how they behave in your app, what features they use most, and what products they buy most often. Analytics will also give you insights on the devices your users most commonly use, your app’s performance, and so on.

Amazon is the largest ecommerce giant in the world, and it has its own grocery delivery and shopping app. Amazon Prime Now offers one- to two-hour delivery that few shops can compete with and allows customers to choose from thousands of products. Essentially, it’s a marketplace that offers delivery from local grocery stores and select markets.

How much does it cost to create a grocery shopping app?

The grocery app development cost can vary a lot depending on these factors:

  • App size
  • Functionality
  • Platforms
  • Technology stack
  • Design complexity
  • Hourly rate of the grocery mobile app developer

The app’s feature set and the hourly rate of developers are the two most influential factors that form the price of online grocery shopping app development. The hourly rate often depends on where your grocery delivery app development company is situated. Eastern Europe has a relatively low cost of living, which is why the price difference between developing in the US and in Ukraine can be fourfold while achieving the same quality.

A full-fledged grocery shopping app can cost from $10,000 to $80,000 depending on your grocery app features. You should also take additional costs into account for third-party solutions like payment gateways or maps along with ongoing maintenance and updates.
