Our Web Application Development Process


Discovery Phase

Our sales team discusses initial requirements with you and guides you with a detailed roadmap and strategies. Our Business Analysts create a WBS and SRS, outlining the cost, timeline, project scope, tech stack, and specific features to be included in your project.


Planning and Designing

Designers, developers, and QA convene for a kick-off meeting to review the WBS and gather team input. A post-sales BA or System Analyst creates a detailed wireframe using Figma and a mind map using Miro is then created to communicate the project scope to the client.


Project Setup

During the design review, we establish the development and staging environments on Gitlab and AWS, while QA sets up tracking and build systems. The PM finalizes the project plan, detailing phases and delivery dates, and liaises with the client for design specifics.


Design Approval

With inputs from WBS, mind maps, and wireframes, our UI/UX designer presents three design variants. Each option is thoughtfully created to align with the client’s vision and project goals. Upon client approval, we transition into the development phase.


Development and QA Execution

Development is executed in agreed-upon phases, integrating client feedback throughout. The QA process runs in tandem, ensuring quality at each step. If change requests arise, they are handled by the sales team, who reassess the scope and secure client sign-off before implementation.



Our technical team publishes the web application on the live server upon receiving QA clearance and client approval. The PM updates the client, effectively transitioning the project to a fully operational live environment for immediate use.

Answers to Common Questions About Web App Development

How much does it cost to build a custom web app?

The cost of developing a custom web app can range from $20,000 to $500,000 or more. However, the cost of building a custom web app can vary significantly depending on various factors, including the complexity of the application, its features and functionality, the technology stack used, development time, and the location of the development team.

What are the factors affecting web app development costs?

Here are the factors that affect the web app development cost.

  • More complex apps with advanced features will require more development time and resources, increasing costs.
  • The choice of technologies, frameworks, and programming languages can impact costs. Some technologies may require specialized expertise and result in higher development expenses.
  • If the web app needs to integrate with other systems, databases, or third-party services, it can add to the development cost.
  • The extent of customization required for the app can influence costs. Highly customized solutions may take more time and resources to develop.
  • Rushed or tight timelines may require additional resources or overtime work, potentially increasing costs.
  • Factoring in ongoing maintenance and support costs is essential for the long-term sustainability of the web app.

How to choose the best web application development company

  • Look for reputable companies through online research, referrals, and industry directories. Create a shortlist of potential candidates.
  • Review the company’s portfolio to see if they have experience in similar projects. Check for the quality and diversity of their work.
  • Inquire about their development methodologies, project management practices, and communication processes.
  • Request detailed cost estimates, including potential additional costs, and compare them with your budget.
  • Review all contracts, agreements, and intellectual property rights to ensure a clear understanding of terms.
