B2C (Business-to-Consumer)

It is the most common model and includes online retailers (Amazon) or clothing brands selling directly through their websites. b2c ecommerce development model is based on the customer experience, the number of products and services one offers, and the ease of transaction to achieve client engagement and loyalty.

B2B (Business-to-Business)

There’s also B2B e-commerce or transactions between businesses, whether it’s a manufacturer selling to a wholesaler or the latter selling to a retailer. The platforms typically process orders in mass quantities, repeat purchases and special pricing arrangements. There are some examples of such businesses, such as Alibaba or the sector supply portals. The emphasis of the model is on efficiency, tailor pricing and standardized purchase flow.

C2C (Consumer-to-Consumer)

C2B (Consumer-to-Business)

Why Invest In E-commerce Development?

Ecommerce app development is an investment that all businesses should consider taking seriously if they are seeking to diversify their offerings, position themselves to react to changing customer behavior, and remain a prominent competitor in the expanding digital landscape. Here are five reasons ecommerce development is an excellent investment for businesses: 

Incredible Range and Availability 

A global ecommerce platform allows for unlimited customer availability. Unlike retail stores that have limitations around geographic location, size of store and market, online stores eliminate limitations as it relates to customers - anywhere in the world - and at any time. In short, the volume of opportunities for ecommerce sales is directly related to the ecommerce business situation. 

Cost Savings 

Ecommerce businesses will drastically reduce or eliminate expenditures associated with a traditional retail business (e.g. rent, utilities, human capital, etc.). In turn, ecommerce businesses may be able to dedicate their extra costs towards marketing, product development or customer service. 

Improved Customer Experience 

Ecommerce platforms more frequently provide a customized shopping experience using more optimized functionalities such as AI-generated product recommendations, optimized checkout experience and ease of use. 

Data-Driven Insights

Ecommerce app development has the advantage of integrating analytics tools that provide data on customer behavior, sales patterns, and inventory. Businesses can leverage this data to make data-driven decisions, optimize marketing efforts, and define products related to demand.

How To Build An E-commerce App?

The time has come for you to learn how to build an e-commerce mobile app. Building an e-commerce app is an investment and an experienced ecommerce app development company can make the process a lot easier.  There are six basic stages of the ecommerce development step by step guide:

Ideation and Requirement Gathering

The ecommerce app development guide begins with your business goals, target audience, and market requirements. An experienced ecommerce development company will collaborate with the client to help you clearly define your idea and requirements, identify core features such product catalogs, cart systems, and payment gateways, and whether you would like to develop for either iOS or Android, or both. This stage sets the stage for success when developing your app.

UI/UX Design

This is the second step in our e-commerce app development guide. Creating an intuitive and engaging user interface is important to win over customers and maintain their loyalty. The e-commerce mobile app development team will work together to create wireframes and prototypes that will help them visualize user journeys. All aspects of the app's aesthetic and navigation will be thoughtfully considered to ensure a seamless shopping experience across all devices, while optimizing the responsiveness of the app.

Backend Development

At this stage of the e-commerce app development guide, the focus is on just building the app's core engine; server-side logic, databases, APIs, and admin panel functions. A well-built back-end allows for real-time updates of inventory, stores data securely, and provides good integrations with third parties like payment gateways, shipping APIs, and CRMs.

Frontend Development

Next, the developers will build the client-side of the app using appropriate technologies according to the platform you selected (e.g., React Native, Flutter, Swift). Your hired ecommerce app developer will be working on the front end and communicating with the back end, pulling data from the back end and displaying it through structured layouts according to the app's Design.

Testing and Quality Assurance

We are so close to the final stage of the e-commerce website development guide. 

Pre-launch, the app is thoroughly tested—functionality, usability, performance, and security are all confirmed. The QA engineers find the bugs, and log an adherence to industry standards. This phase decreases post launch issues, and improves user satisfaction.

Deployment and Maintenance

Last step of the e-commerce website development guide, once approved, your app gets deployed to app stores. A good ecommerce app development company can also offer post launch support, take performance measures, fix issues, and push updates. They can also help you scale your b2b e-commerce development with newfound features as your business grows.

How Much Does E-Commerce App Development Cost?

The e-commerce app development cost can range for $15,000-$49,000+, Depending on the overall complexity and features expected, and the area in which your company is in. Here are eight key aspects affecting the development cost, with each aspect explained, then followed by a cost table for reference.

1. Platform (iOS, Android, or Both)

Developing only for Android or iOS has an effect on eCommerce app development cost compared to building for both platforms. Cross-platform app development frameworks like Flutter can help reduce development costs, but there may be some loss on performance or customization.

2. UI/UX Design 

A simple, basic design with off-the-shelf templates won't break the bank, however if you want custom UI/UX with animations, micro-interactions, responsive design, and flow for the best user experience with your eCommerce app development; all of these features will cost you substantially more in design hours.

3. Number of Features 

When developing an eCommerce app, whatever features you want to include (you may be considering wish lists, bots, loyalty programs) add some difficulty and certainly development time to your project. An eCommerce app with minimal shopping features to allow for a purchase, would be at the lower end of the price, while an app with rich interactive features that require a lot of backend work, and API integration, will have the highest price tag.

4. Backend Structure 

High-end backend structure such as; hosting, a website to manage orders, managing users, an inventory database, and access to analytics, all contribute.

Cloud-based, scalable backends with strong security features can drive development and maintenance costs up but provide long-term stability.

5. Third-party Integrations

Integrating your ecommerce app with payment gateways, shipping APIs, CRM, or ERP can be super convenient, but these integrations can take time to set up and work through bugs and glitches before they go live, which can add to the total e-commerce app development cost.  

6. Development Team is Located

The cost for hiring ecommerce developers is one more of the driving factors in calculating the development cost. Developers in North America or Western Europe will bill $80-$^200/hour, while the whole development team in Asia (India, Philippines) will cost $20-$50/hour.  Where your developers are located will drastically affect the cost for the project to develop an e-commerce app.
