Checklist before Building an eCommerce App

Many entrepreneurs made the mistake of jumping on the eCommerce bandwagon and building an eCommerce app without giving much thought to the business model. To avoid such mistakes we have prepared a checklist that one must go through before you develop an eCommerce application.

Research the eCommerce app idea

Insufficient research about their eCommerce app idea is the reason why many eCommerce apps fail. First, the entrepreneurs must b e clear about the kind of eCommerce app they want to develop . If the business produces its own goods, it can choose to develop an eCommerce app to attract more customers and increase online selling. The other idea is to create an eCommerce aggregator app and let others sell their goods on the eCommerce app.

No matter what kind of eCommerce app the business wants to develop, it must first summarize the idea and answers the question: what are the key issues that the app will solve?

Any robust business plan starts with a clear business idea. If the business wants to go to investors to raise money, the investors would check whether the company has a well-thought-out business idea.

Create buyer personas

Specifying a target audience in detail is the next step after identifying the business idea. No business can succeed in the online world without knowing who its customers are. Creating detailed buyer personas is the way forward for eCommerce companies if they want to succeed. While creating buyer personas, the businesses should consider all the components like

  • Age
  • Demographics
  • Economic background
  • Hobbies and interests

eCommerce businesses must understand their needs and motivations and also know what influences their buying behavior. By creating a detailed buyer persona, an eCommerce company would design an app that will engage the customers and boost customer acquisition and sales.

Assign a budget for the app

Considering the type of eCommerce app they want to build, the eCommerce company must have a clear budget. The budget of the app will depend on the kind of features and technologies that the business wants to integrate in its app.

Choose the perfect mobile app platform

One of the most critical decisions that an eCommerce company needs to take is on which platform it would develop its eCommerce app. While choosing a platform, the company must ensure that the platform meets the latest technical requirements and reaches a broader audience. Many companies prefer to develop their eCommerce apps both in Android as well as iOS. The eCommerce app owners should also make sure that their eCommerce mobile app is compatible with wearable and IoT devices, like smart watches and biometric scanners respectively, as the popularity of such devices are on the rise.

Competitor analysis

Most of the eCommerce niches are overcrowded and this is why new entrants need to conduct a thorough competitor analysis before developing an eCommerce app. Entrepreneurs must define their niche and conduct proper analysis using the available information. By conducting a proper competitor analysis, eCommerce app owners can prepare a better strategy to position their app in the market.

Focus on the app’s wireframe

The app’s wireframe must be built in such a way that it includes various categories, sub-categories and pages. The eCommerce app owners should have the app designed in such a way that the navigation, redirects and CTAs are meaningful and work properly. The feedback of the team members plays an essential role in deciding the nature of the wireframe. Spending time designing a proper wireframe is vital because the users won’t be able to find what they are looking for if the app has unordered elements, lacks clear CTAs and has a flawed color scheme.

Build MVP

MVP or Minimum Viable Product is the most basic version of an app with only the necessary features and hence it also be called the first-version of your most viable product. Before building a full-fledged mobile commerce app with all the bells and whistles it is important to identify whether the business model works as expected. This is where an MVP can help. The app owners can build an MVP, get the suggestions of users regarding the app, the kind of features that they would like to see in future version of the app and the features that are not required. The developers can then add/remove the features of the app according to the user feedback.

Custom eCommerce application development helps in meeting the evolved users’ needs.

Improved brand recognition

Personalized shopping experience

With hundreds of eCommerce stores providing the same category of products/services, then it’s difficult to appeal to the users and make them shop from your store. The Ecommerce application development leveraging the power of AI technology enables engaging the customers with smart recommendations right at the moment they are browsing the store, or after a couple of minutes, they leave the app by analyzing browsing patterns or purchase history.

When customers receive notifications tailored to their preferences, the chances of conversion and retention are more. Ecommerce apps are powerful in analyzing every touchpoint, connecting the dots, and making the right suggestion at the right time.

Tap the marketing opportunities

The custom messages that are relevant to the users’ preferences are well-received by the users. For instance, sending discount-related notifications to the users just after they left the store after browsing a product of a specific category improves the chances of revisiting the app and completing the purchase.

The probability of getting in-app push notifications read by the users is higher as compared to messages or emails. Ecommerce stores can use in-app notifications as their marketing communication tool to speak loudly and bring maximum actions.

Preparation and planning

In the preparation and planning stage, the eCommerce app owners need to conduct marketing research, build technical requirements for the app, prepare a budget and find the team to help the owners build the app.

Defining features

In this stage the eCommerce app owners decide on essential features of the app, list them out and prepare a particular product tech requirements document. While defining the features, the eCommerce app owners should think about the platform, the programming languages to be used and the data frameworks that will support the eCommerce app.


The UI / UX of the app happens to be the most critical component of the app. While designing the app, the designers should focus on the expectations and needs of the users. The following are some hints for designing a good UI / UX interface.

  • Keep the menu simple
  • Use large images
  • Use motion design
  • The catalog should have significant filters to present the products
  • Information about the prices of the products and payment methods should be clearly visible


This is the phase where the actual and coding happens. The developers prepare a front-end as well as back-end code in this phase. While coding the eCommerce app, necessary care should be taken to ensure that quality control is maintained in all the modules. The security, stability and scalability should be maintained while preparing the code of the eCommerce app.


An eCommerce app should be able to conduct multiple transactions simultaneously without a hiccup. There are an infinite number of situations that could occur and spoil the user experience. To prevent these situations from occurring, robust testing is required. The eCommerce app owners should ensure that the app undergoes functional, user, device and integration testing and then start fixing the bugs. In most cases several rounds of testing are required to ensure that everything works properly.

Deployment and maintenance

Deployment is the final stage of the app development process. In this stage the app owners deploy the app on app stores and sort out any bugs that arise post-deployment. Regular updates and maintenance of the app are absolutely essential to ensure that the app functions smoothly. While updating the app, the entrepreneurs must ensure that they listen to the customers’ feedback and provide new features in their app.

Must-have features in an eCommerce app

Although the features in one eCommerce app can vary from other eCommerce app, there are a few basic features that any good eCommerce app must have. Let us discuss these essential features in the following section.

Log in and personal account

In order to personalize the app content and provide the users with a great experience, some basic details like name and address must be stored in the app’s database. For this purpose, an eCommerce app should have a sign-up and sign-in feature, asking the customers some basic details. The app then should store these essential details in its database. This feature would make the experience of the app’s users smoother as they won’t need to re-enter their details every time they make a purchase. The app owners can also benefit by providing this feature as they would know exactly what the interests of their customers are.


No eCommerce app is complete without providing a detailed catalog of the products that it sells. While preparing the catalog, care must be taken to ensure that the catalog contains big images and clear category names. The product pages should have clear descriptions of products, the prices should be clearly visible, estimated delivery dates should be mentioned and the product pages should have an add-to-cart button.

Shopping cart

The shopping cart feature is one of the most basic features in an eCommerce app. In this feature, the users add products to their shopping cart which they can buy later. The shopping cart feature provides a lot of convenience to the shoppers as they can save multiple items to their shopping cart. Once the users have selected all the items, then they can purchase them all at once.

Search feature

In most cases people are searching for specific products in an eCommerce app. To make sure that the customers quickly get what they want, the eCommerce app must have a search box. The eCommerce app owners can make the searching process easier and convenient for their users by developing a convenient menu and a search bar. The search box should be available on all pages and should be distinctly visible.


A Chatbot is one of the most powerful eCommerce tools that an eCommerce app can have. Chat board provides 24/7 customer support and offloads a lot of work from the shoulders of customer care executives of the eCommerce company. A Chatbot helps the eCommerce app become more accessible to its customers. They can answer basic questions like the delivery date of the product, questions related to returns and replacement, payment failure at their convenience.

In case the Chatbot is unable to resolve the issue, it will then forward the issue with all the necessary details to the customer care executive. The customer care executive would already know the background of the problem and hence would be able to resolve the issue faster.

Admin panel

The admin panel helps the eCommerce company manage the app. Through the admin panel, the eCommerce app owners can

  • Add and remove the products
  • Add and remove the sellers in case of aggregator apps
  • Resolve clients issues
  • Change the images of the products
  • Change the pricing details of the products
  • View the analytics

Payments and payment system integration

Payment security is absolutely essential for any commerce app as nobody would like to use an insecure eCommerce app. Following the GDPR practices is a prerequisite for any app and is true for the eCommerce app also. The eCommerce app could either have a custom payment instrument that would interact with the banking system or just use some readymade plugging. A secure payment system would ensure that the users and the app owners do not face any hiccups.

Real-time analytics

The analytics tools like Google analytics help the app owners get real-time insights into customer behavior. The analytics tells the app owners regarding the following important metrics of eCommerce.

  • The total time spent on the app by the users
  • Total transactions in a specific time frame
  • The pages and products that the customers have frequented the most
  • App bounce rates
  • Most purchased products

The data gained from analytics can be used to improve the user experience. The data also helps the app owners to create targeted advertisements that improve the conversion rate.

Push notifications

Push notifications help boost the app’s engagement levels with its users as it constantly reminds the users about the app. The push notifications let the users know about the new offers on their favorite products. Via push notifications, the app owners can also provide the delivery status of ordered products to the customers.

Social media integration

The social media integration feature will enable the users to share information about their favorite products with their friends. The social media integration tool will act as a great marketing medium for the app and help boost the engagement levels of the app.

High-quality yet compressed graphics

The first thing that attracts the users towards the products listed on the eCommerce app is its beautiful image. Powerful photos have a great significant impact and help in the favorable placement of the product in the consumer’s mind. Hence the eCommerce apps should make sure to put up high resolution photos and videos of the products on their app.

An important thing that the eCommerce app owners should take care of is to ensure that the size of the graphics is compressed. The size is compressed to make sure that the images and videos load faster on the app. This is done to make sure that the app experience is smooth for the user. If not compressed, the graphics and videos will take time to load and along with the user experience, also affect the SEO rankings of the app.

Review and rating

No eCommerce app can succeed in the cut-throat competition of the digital world without listening to its customers. The app owners should have a review and rating section for each product and explicitly ask for honest reviews from customers who have purchased the products. Once enough data is acquired about the customer preferences about the products, the eCommerce app can then have a most popular and best-selling goods section. This section can prove to be an excellent way to highlight the most successful products on the eCommerce app and increase sales. Honest reviews about the products also help increase the eCommerce app’s reliability as these honest reviews help the customers make informed decisions.

Wish list

The wish list section helps users create a list of products that they would like to buy later. The wish list section of the app helps the app owners gather essential data regarding the customers’ preferences. Using the data gathered from the wish list section, the app owners could then notify the customers when the prices of their favorite products have dropped, nudging them to make the purchase. A great idea to use the wish list section is to let the users share the wish list products with their friends before important events like anniversaries and birthdays.

New-age technologies to include in an eCommerce app

Up till now we have covered the basic features of an eCommerce app. Now we will cover some new age features which one can think of including in an eCommerce app. These new age technologies will help in improving the user engagement of the app.


Augmented and virtual reality technology has taken the world by storm. The eCommerce apps are no exception to it and various retailers like H&M and IKEA are utilizing the power of AR and VR to boost the engagement level of their customers with their brand. The beauty of AR and VR is that the products are displayed in 3D. This feature of augmented and virtual reality helps the eCommerce app create a virtual showroom where the customers can try anything from spectacles, clothing to furniture. Including an AR and VR feature in the economics, the app will definitely boost the sales of products featured and help distinguish the eCommerce app from its competitors.

Voice search

The rise of voice assistants like Amazon Alexa and Google Assistant has fueled the growth of voice commerce. According to forecasts, voice-enabled commerce will grow to $80 billion by the year 2023. Businesses that are not paying attention to voice commerce are missing out on a huge opportunity. Voice search makes eCommerce more convenient for users as it is much easier to search for products using voice than typing it. Voice search also makes it pretty easy to give feedback regarding the purchased product. Instead of typing long reviews, the voice assistants could get the customers’ feedback by asking them a few questions regarding the purchase. As shown in the image given below, customers have purchased many things using voice search.

The eCommerce app can improve the convenience of the customers by adding the voice search function to it.

Visual search

Another emerging new technology in eCommerce is that of visual search. The feature allows customers to shop using their camera. Using visual search, the users can upload images from their social media profiles, mobile gallery or web page. The users can look for products similar to the image that they have uploaded. Visual search has gained traction amongst gen Z and millennials. Companies like Pinterest are already using this technology in their mobile app.

Alibaba, one of the world’s largest eCommerce companies, has used the power of visual search in its visual search engine Palitao. The company started the service in 2014 and reached 10 million unique visitors within a short span of 3 years.

Artificial intelligence

AI-powered search engines, also known as the insight engines, help eCommerce apps enhance traditional search engines’ power by combining them with sophisticated machine learning algorithms. The primary benefit of using insight engines is that these engines help make the internal search more accurate and personalized.

Using applied statistics, AI-powered eCommerce apps can maximize the probability of a sale happening by coming up with the right product at the right time. AI can also help an eCommerce app in its back-end services like inventory management. AI can play a vital role in improving the damage detection of goods not to receive damaged goods. AI can also help improve the product flow in the warehouse, effectively reducing the delivery time. Using the power of AI, the eCommerce app can improve its UX.

Cost of developing an eCommerce app

The eCommerce app development costs between $40,000 to $200,000. However, providing an exact development cost is impossible because the Ecommerce mobile app development requirements from different business clients cannot be set in stone. There are various factors on which eCommerce development cost depends that we will discuss in detail.

The cost of developing an eCommerce app depends on a lot of factors like

  • The number of features included in the eCommerce app
  • The location of the app development company
  • The number of users that the eCommerce app wants to cater to
  • The type of vendors(freelancers, in-house development team or a remote professional development company)
  • Number and nature of third-party services needed to be integrated with the app
  • Marketing and SEO costs

As the number of features and the complexity of the app increases so does its cost. For instance, if a company wants to build a simple eCommerce app with just the basic features like login customer login and payment, it won’t be that costly compared to developing a full featured eCommerce app with features like AR / VR and sophisticated AI algorithms.

The location of the app development company also plays an important role in determining the final cost of the product. If the app developers are located in North America or Europe, they will charge around 8 to 10 times more than their counterparts in a developing country like India.
