Fixed-Fee App Development & Delivery Services (Waterfall)

Want to pay a fixed price for your project? Our waterfall method ensures predictable timelines, clear milestones, and structured, reliable delivery for your mobile app projects.

Example
Example
A Fixed Plan Delivered for a Fixed Price

Our Waterfall project development process follows a structured, sequential approach. This method involves defining the entire project requirements at the outset, quoting for it, completing the work, and then releasing and maintaining the final product.

This approach is best suited to customers who require a fixed-price project delivery, rather than prioritising agility and the ability to adjust requirements on a month-by-month basis. Typically, we plan and estimate the project upfront before contracting based on that plan.

Exampled
Structured and Predictable Project Planning

At the beginning of each waterfall project, we conduct comprehensive planning and requirement-gathering sessions with all stakeholders.

This thorough upfront planning stage clearly defines your project's scope, timelines, and deliverables. It reduces risks, prevents scope creep, and ensures alignment from day one, giving you clarity, control, and confidence throughout the development lifecycle.

Example
Reliable, Phased Development Process

Our waterfall development process proceeds in clear, well-defined phases, allowing systematic and efficient progress tracking.

Each stage—from initial build to testing and deployment—is carefully managed and documented, with clear milestones and approval checkpoints. This ensures maximum transparency, quality assurance, and predictability throughout your project's lifecycle.

Example
Testing and Quality Assurance

Quality and reliability are at the heart of our waterfall approach. Each app undergoes a comprehensive QA process before final delivery, starting with internal testing before being released to you for User Acceptance Testing. Our approach ensures that your app is robust and meets your specifications as outlined in planning.

Frequently Asked Questions

Q) Who should choose Waterfall app development?

Waterfall development is ideal for projects with clearly defined requirements, fixed budgets, and timelines, such as corporate apps or startups looking to build their very first app with tight budgets that cannot afford scope change mid-way through.

Q) How long does a waterfall project typically take?

Project duration depends on complexity and scale, but clear phases and structured processes mean we can provide reliable timelines upfront, typically ranging from several weeks to several months.

Typically, we recommend delivering a brand-new project within three to six months. If it's shorter than that, it's likely a small project. If it extends beyond six months, you may be defining too many requirements upfront. In that case, consider a minimum viable product approach—streamline phase one to launch something smaller, leaner, and sooner, allowing you to test early assumptions.

Q) Can changes be made during development?

Ideally, with the Waterfall approach, changes are not made mid-development with the Waterfall approach. Sometimes, we can accommodate changes when necessary, but it's not ideal—it’s inefficient and can disrupt the project timeline and budget.

If you require flexibility to make changes during development, we recommend the Agile project delivery approach over Waterfall. The Waterfall method is best suited for projects where requirements are locked in before development begins.

Q) Will I have visibility throughout the development process?

Absolutely—we provide regular updates, milestone reviews, and complete transparency at every stage, ensuring you always know the project's status.

Q) What happens after the project is delivered?

We offer ongoing support, maintenance, and further enhancements to ensure your app remains updated, secure, and effective after launch. The support and maintenance approach we recommend will depend on your needs. For example, apps with greater scale and user growth may require a different support and maintenance arrangement than those without.
