      Silvertech helped to bring our new, comprehensive hospital website to fruition. We went from a static, outdated site to a progressive, visually enticing and simple-to-navigate site with Silvertech's help. In the first 3 months upon launching the new site, we had over 100,000 page views by over 20,000 visitors, with traffic averaging 6-8 times that of our old site. And with 20,000 visitors, we have only had one user not able to find what she was looking for. Great end product, and a terrific team at Silvertech! 2014 Update: website has one of the lowest bounce rates in New England, has had over 1,000,000 page views, and received the NESHCo Award for best redesign.

Frequently Asked Questions

What is an eCommerce app development company?

An eCommerce app development company is a company that creates mobile and web applications specifically for the eCommerce sector. These companies combine expertise in software development, user experience (UX) design, and digital marketing to develop platforms that facilitate online buying and selling of goods and services.

Beyond coding expertise, eCommerce app developers deeply understand eCommerce functioning, including online payment systems, security measures that protect users’ data, and third-party integrations with various marketing and sales platforms. Their extensive knowledge allows them to create user-friendly, scalable, comprehensive solutions that improve customer engagement and drive sales.

An eCommerce app development company optimizes apps and provides solutions for these challenges by:

  • Ensuring a responsive app design
  • Developing user personas
  • Customizing product catalogs and checkout processes
  • Multi-language and multi-currency support
  • Integrating digital marketing best practices
  • Utilizing the right technology stack, including programming languages, frameworks, and databases

With the global market size projected to hit around $57.22 trillion by 2032, eCommerce has firmly established itself as an integral part of the global economy. Businesses across various industries hire eCommerce app developers to ensure their brand’s relevance and growth in the future market.

The importance of hiring top eCommerce app developers is perfectly illustrated in McDonald’s case study:

A globally recognized food chain wanted to improve its mobile presence worldwide to provide its customers with a superior and more personalized ordering experience. In response, Apptunix developed a custom mobile app with a comprehensive product management system that allowed multiple orders to be placed simultaneously. The solution integrated advanced analytics so McDonald’s could track performance and bring data-driven decisions. McDonald’s achieved the following results:

  • 64% increase in the number of orders
  • 54% improvement in customer satisfaction and engagement
  • 13.56% boost in conversion rate
  • 5x boost in overall sales and ROI
  • 4.5 million downloads across Android and iOS platforms

Should I develop a mobile app or a website for my eCommerce business?

You should develop a mobile app and a website for your eCommerce business because both can contribute largely to your goals.

While websites are the foundation of your business’s digital presence, having a mobile app makes your products accessible to your audience 24/7. Moreover, apps load much faster, have user-friendly features, and can work offline.

While the desktop is vital for eCommerce, it is worth noting that 58% of all purchases are completed on mobile. Furthermore, eCommerce stores receive 60.66% of traffic from mobile users, compared to a modest 37.08 from desktop devices.

Looking ahead, the number of digital shoppers is expected to reach 2.77 billion by 2025 globally. In the US alone, 92% of consumers under 50 are most likely to purchase via mobile devices. This trend underscores the increasing importance of developing mobile platforms for the eCommerce sector.

What are the different kinds of apps developed by the top eCommerce development companies on DesignRush?

The different kinds of apps developed by the top eCommerce development companies on DesignRush are web and mobile applications, which can further be categorized in the following ways:

By the type of client:

  • Business-to-consumer (B2C) apps: Streamline the purchase by connecting businesses directly with customers.
  • Business-to-business (B2B) apps: These are software solutions designed for transactions between businesses. They usually have more complex integrations to optimize the commercial journey and operations.
  • Consumer-to-consumer (C2C) apps: Enable transactions between individual consumers. C2C platforms serve as intermediaries where individuals can post an item for sale, bid for products, or transact directly with the seller.

By the mobile platform:

  • Native apps: Developed specifically for one operating system (Android or iOS), these apps provide the best performance and UX. They use device hardware and software, providing seamless integration with other apps.
  • Hybrid apps: Developed using web technologies (HTML, CSS, and JavaScript) and then wrapped in a native app shell, these apps operate across multiple platforms from a single codebase. They can access device features through the native shell but may have slower performance and a less seamless UX than native apps.
  • Cross-platform apps: Created using frameworks like React Native or Flutter, these apps allow developers to write a single codebase that compiles into native code for both iOS and Android. These apps offer a performance and UX that closely mimics native applications, using the efficiency of shared code across platforms while maintaining a high quality in interaction and design.
  • Progressive web apps (PWAs): Blending the best of web and mobile apps, PWAs offer an app-like experience in a web browser. They're fast, reliable, and work offline, making them increasingly popular for eCommerce.

We can see a prime example of successful app development in the case study of Cubix, an eCommerce app development company with a track record of deploying high-value applications.

The eCommerce app developers were tasked to build an intuitive grocery delivery app for those in need through community support. Cubix built the app with user-friendly navigation, live mapping, and robust security, which produced the following results:

  • Over 5,000 user registrations
  • Nearly 2,000 grocery lists posted by recipients
  • 54% of grocery lists were funded by contributions
  • More than 12,000 grocery orders fulfilled
  • Year one revenue surpassed initial projections
  • Expanded partnerships and neighborhood support

What services do eCommerce app development companies offer?

eCommerce app development companies provide end-to-end services from market research, ideation, UI/UX design, QA testing, implementation, and integration to app maintenance and support.

The main eCommerce app development services include:

  • Ideation and product design: Ideation is the initial phase of the app development process; it involves finding the gaps in the market, the intended audience, and the problems the app aims to solve. Product design includes creating user personas, prototyping, and UI/UX design. It ensures the product is user-friendly, viable, and feasible.
  • Mobile app development: This service focuses on creating applications for mobile devices, including smartphones and tablets. Mobile app development can be divided into native, cross-platform, and web apps (responsive websites that look and feel like an app). The service includes front-end (client-side) and back-end (server-side) development.
  • Software development: This service includes the creation, design, deployment, and maintenance of software solutions. It covers mobile app development and other types of apps, such as web apps, desktop applications, and system software.
  • Digital transformation: This service uses digital technologies to improve the shopping experience, operations, and customer interactions. It can include integrating AI for personalized shopping experiences, adopting mobile-first approaches, using social media channels for marketing, and big data for customer insights.
  • Cloud services: Cloud services offer scalable, flexible, cost-effective solutions for hosting online stores. Cloud platforms enable eCommerce apps to handle spikes in traffic during sales or holiday seasons without compromising performance.
  • Blockchain services: Blockchain improves the security and transparency of online transactions, making payments safer and preventing fraud.
  • Data science and analytics: This service provides access to more complex insights that can help in faster decision-making with reduced risk. It utilizes disruptive technologies such as business intelligence (BI), data warehousing, data visualization, big data, and supply chain analytics to give a more accurate forecast about your business.
  • DevOps: Ensuring that your app stays on top of user demands, bugs, and updates, DevOps sets you apart from the competition. It is done through the CI/CD DevOps models or continuous integration (CI) and continuous deployment (CD). It automatically allows the app to update without crashing, reducing costs and downtime for the business.

How much does eCommerce app development cost?

eCommerce app development costs between $5,000 to $500,000, depending on the app’s complexity. It gets more expensive the more features and functionalities you add.

Here is how the pricing varies with the app’s complexity:

App complexityAverage cost
Basic eCommerce apps$5,000 to $50,000
Mid-range eCommerce apps$20,000 to $120,000
Complex eCommerce apps$150,000 to $500,000

Price also changes depending on the mobile platform you opt for: 

Type of application by mobile platformAverage cost
Native apps (Android and iOS)$20,000 to $100,000
Cross-platform apps$25,000 to $60,000
Web apps$15,000 to $50,000
Hybrid apps$10,000 to $150,000

Here’s a breakdown of the factors affecting the application’s complexity and their approximate cost:

Factors affecting costAverage cost

Testing$5,000 to $20,000

On DesignRush, the top 50 eCommerce app development companies charge an average of $350/hour. Roughly 18% of the eCommerce app development services on DesignRush accept projects with a minimum budget of less than $1,000, while 2.6% require a $50,000+ minimum budget.

Why should I hire an eCommerce app development company?

You should hire an eCommerce app development company to leverage its expertise and resources and create a user-friendly, scalable, and secure online store.

They can elevate your online store by:

  • Boosting sales: eCommerce app developers employ a customer-centric approach, crafting apps that leverage insights from consumer purchasing behaviors. This strategy includes features like push notifications, personalized recommendations, and a seamless app experience, all of which drive increased engagement and ultimately, higher revenue.
  • Improving UX: By focusing on dynamic UI and UX design, eCommerce app developers can improve the shopping experience within your app. This includes integrating intuitive navigation, multiple payment options, and support for various languages, making the consumer’s journey through your app more enjoyable and efficient.
  • Elevating brand visibility: By optimizing your business for search engines through keywords, metadata, and structured data, eCommerce app development companies can enhance the visibility of your business in search engine results pages (SERPs) and digital marketing channels.
  • Buildng trust and loyalty: A seamless online shopping experience fosters a positive relationship with your customers. eCommerce app developers can enhance this relationship by rolling out regular updates to address user concerns, ensuring secure payment transactions, and managing data effectively, which in turn, builds customer trust and loyalty.
  • Unlocking new demographics: With Gen Z accounting for over $450 billion spending power globally, their shopping preferences cannot be ignored. Partnering with an eCommerce app development company can offer innovative solutions tailored to this young audience. Features like a sleek UI, personalized experiences, and a streamlined checkout process can help captivate these savvy consumers, unlocking new avenues for growth.

Suffescom Solutions’ example illustrates the value that an eCommerce app development company can bring to your business:

Mealed, a food-ordering mobile app, faced numerous challenges regarding customer attraction, SEO, marketing strategies, and revenue. To augment these challenges, Suffescom Solutions built an interactive customer management panel, multi-lingual food marketplace, in-app chat and calling features, and multiple payment gateways like PayPal, Stripe, and Zelle, among others.

Through this collaboration, Mealed achieved the following milestones:

  • Over 50,000 in-app orders, with a 56% increase in food orders within the first two months
  • 43% lower delivery costs
  • 56% increased return on investment (ROI) within three months
  • 25% increased customer base due to multilingual platform
  • More than 10,000 app downloads
  • 5.0 stars in Google Play Store reviews

How do I choose the best eCommerce app developers for my business?

To choose the best eCommerce app developers for your business, follow these steps:

  2. List down app features: Create a list of app features and the integrations your app should include. Decide what platforms to focus on: iOS, Android, or a hybrid app?

  7. Consider the location: Knowing the location of the eCommerce development company is essential, especially if you hire augmented staff. Consider the time zone alignment, the communication channels, and language and cultural barriers.
