    Tailoring Web Applications To Fit Your Business

    Endertech builds custom web applications that fit unique business requirements. Instead of shifting your rules to accommodate off-the-shelf software, we build one that aligns with your business’s workflow. More importantly, custom web apps are scalable, cost-friendly, and let you reach precise goals without doubling the development effort.

    What is a custom web application?

    A web application is a software with browser-based access that behaves like native apps. Unlike a website, it provides advanced features that support various business needs, such as:

    • eCommerce – web apps enable eCommerce features like shopping cart, payment verification, and inventory management.
    • CRM software – custom CRM web app features include customer engagement, sales tracking, and marketing campaigns.
    • Social media – scrolling, feed personalization, and user engagement are common social media web app features.
    • Productivity tools – with a web app, you can easily manage projects, share documents, and collaborate with team members.
    • eLearning – it allows trainers to publish courses and assess learners effectively.

    5 reasons to build custom web apps

    Businesses turn to custom web apps for consumer-facing solutions, internal process management, secure log-in portals and other reasons.

    • No installation is required. Web apps are independent of operating systems. They run on mobile devices, tablets, and desktop computers from their web browsers.
    • Better security. Instead of approaching security in general, we consider the security needs of each business when developing custom web apps.
    • Web apps are scalable – both horizontally and vertically. You can increase computing capabilities as your users grow or add new features for emerging business needs.
    • Cost-saving. Instead of developing different codebases for iOS, Android, Windows, MacOS, and other operating systems, we build once and deploy on all devices.
    • Streamline operations easily – Companies use web apps to automate repetitive processes instead of putting together multiple off-the-shelf apps.

    Custom Web Apps In A Connected Business Space

    Digitalization has shifted most businesses to the cloud, with many apps trying to fill your different business needs. We help companies match their growth strategies with data security, user engagement, scalability, and integration by offering a single, cost-viable solution.

    Endertech spares your team from tediously learning how different apps can exchange data safely and reliably—or being locked up with specific vendors. We put control back into your hands by providing custom web developments fitted to your exact needs.

    With your vision and our expertise, we deliver a custom solution that connects your business to an expanding digital space.

    Custom web app development – key features

    While each web app is unique, they share overlapping characteristics. Whether building a custom web app for eCommerce, CMS, CRM, entertainment, or internal use, Endertech ensures that it ticks these crucial checkboxes.

    • Security
    • Scalability
    • Integration
    • User experience
    • Customization
    • Reports and analytics


    We develop custom web applications with your growth in mind. Our approach is designed to handle increasing traffic, data, and users without rebuilding the software. We host microservices on distributed servers, which provides the exact computing resources your web app needs on demand.

    Our team keeps an eye on potential bottlenecks that affect performance, stability, or app maintenance. We believe in keeping the app architecture simple, including the frontend, backend, data storage, and web servers.


    Endertech secures your custom web app against digital threats and vulnerabilities. Our team applies best coding practices, secure frameworks, and trusted third-party services to ease your customers’ minds when using the app. We explain top Javascript vulnerabilities and solutions here.

    Beyond increasing app resiliency, we help companies meet stringent security and privacy requirements, such as PCI-DSS and HIPAA. We also implement in-app security features, such as multi-factor identification and identity access management, to regulate access.


    We don’t believe in reinventing the wheel, particularly if it involves a custom web app. While it’s necessary to implement business-specific logic, we integrate the app with trusted 3rd party services for standard functionalities. For example, we’ve integrated a Magento eCommerce store with an existing ERP system.

    To perform seamless integration, we use APIs provided by external software. API allows the web app to exchange data safely with 3rd party services and easily introduce new features to the web app.

    User experience

    User experience, or the lack of it, affects user onboarding, retention, and engagement on custom web apps. With that in mind, we take a user-centric approach in every stage of web app development. Our product managers validate software assumptions by interviewing or surveying users.

    Through experience, we know that involving users during development reduces software risk and allows us to map user journeys accurately to the app. The results? Engaged and happy users using the custom solution to solve real problems.


    Unlike its off-the-shelf counterpart, web apps are highly customizable even after deployment. We provide in-app configurations to personalize the app for specific users, alter the layout, or activate advanced features for administrators.

    Our in-depth knowledge of scripting languages like JavaScript, CSS, and HTML allows us to support different dynamic content on the app. Likewise, our familiarity with backend frameworks like Ruby on Rails, Node.js, and Django lets us modify or introduce new backend processes.

    Reports and analytics

    Besides addressing user needs, we provide reporting and analytics features for custom-built web apps. Web apps collect data from various user touch points, and these data can provide valuable insights to support better decision-making. For example, a high bounce rate might call for a revised landing page in eCommerce web apps.

    Our team turns complex data into business-friendly formats with graphs, tables, charts, and reports. We let you generate custom reports and share them easily with key stakeholders.
