Approaches within the Fixed Price Model

Fixed Scope, Fixed Budget

This is the most common model. All requirements, deliverables, timelines, and milestones are defined before the work starts.

Best for: Projects with clear specifications, few changes, and strict budgets.

Discovery to Fixed Price

If your project is not well-defined, we need to start with a short Discovery Phase. After clarifying the scope, our team sets a final fixed price for development.

Best for: MVPs, new product ideas, or complex systems that require initial research.

Milestone-Based Fixed Price

We divide the project into smaller phases. Each phrase has a fixed price and deliverables. You just pay only when our team achieves each milestone.

Best for: Larger or long-term projects that need predictable checkpoints and tight budget control.

Fixed Price with Change Control

The main scope stays fixed, but you can add new features through a change-request process.

Best for: Companies that want predictability while still maintaining some flexibility.

Our Fixed Price Software Development Process

Discovery & Need Gathering

Begin with the Project Manager, Business Analyst, and client to identify business goals. Our team conducts interviews with key stakeholders to analyze needs, collect requirements, and user workflows. This step establishes a well-defined project scope.

Scope Definition & Project Roadmap

Translate requirements into a detailed Work Breakdown Structure (WBS). We define all deliverables, milestones, and timelines. Then, estimate the effort, cost, and duration for each module. Finalizing the scope early avoids scope changes and ensures predictable results.

Contract & Engagement Finalization

We complete the contract that includes cost, timeline, deliverables, and service-level agreements (SLA). We adhere to strict compliance with ISO 9001, ISO 27001, GDPR, and IP protection standards. Our team also sets up change control, approval workflows, and assigns a dedicated team.

PoC / MVP Launch (Optional)

When needed, we develop a PoC or MVP to confirm key features and gather real user feedback. This allows us to refine requirements and confirm functionality before proceeding full scope.

Software Development

Our software developers follow Agile methodologies, developing the product in sprints. We conduct demos and provide regular progress reports for full transparency. Clients collaborate with us and make milestone-based payments after each successful delivery.

Quality Assurance & UAT

We execute manual and automated testing for functionality, regression, performance, and security checks. Together with clients, the QC engineer conducts User Acceptance Testing to confirm quality. Our continuous integration and deployment pipelines ensure every milestone meets high standards.

Deployment & Go-Live

Saigon Technology uses DevOps best practices to deploy software with zero downtime, like blue-green or canary releases. We perform complete system validation, provide end-user training, and deliver thorough technical documentation. Finally, we launch after client approval of all deliverables.

Post-Launch Support & Maintenance

Our team offers SLA-driven maintenance services, including bug fixes, patches, and performance optimization. We always check, report, and improve to ensure ongoing stability, scalability, and security. This builds long-term partnerships to support your future needs and growth.

How does the Fixed price model differ from models like Time & Materials or Dedicated Team?

Unlike Time & Materials (pay by the hour) or a Dedicated Team (manage long-term resources), the Fixed Price Model gives you complete certainty over cost and timeline. At Saigon Technology, we define your project scope, milestones, and deliverables upfront. So, you always know the process, the deadlines, and the exact cost. No surprises, no hidden fees!

What type of projects work best under the Fixed Price Model?

The Fixed Price Model works best for projects with well-defined requirements, such as:

MVPs (Minimum Viable Products)
Corporate systems or enterprise software
Web and mobile applications
Platform modernization projects

If you outline the success metrics from the start, this model helps deliver the project on time and keeps everything clear. Businesses can focus on growing without worrying about unexpected costs.

How does Saigon Technology estimate a fixed price for my project?

We start with a Discovery Phase. Our Project Manager and Business Analyst work with you to:

Understand your requirements and business goals
Analyze technical complexity and resource needs
Build a detailed roadmap with milestones and deliverables

When the scope and timeline are agreed, we provide a fixed-price proposal (typically starting from around $8,000) depending on project complexity. After approval, the price is locked and divided into milestone-based payments.

What happens if I want to change the scope during development?

No problem! If you need to add features or adjust requirements, we handle them as separate change requests or mini-projects. This way, your original timeline and budget stay intact, while still giving you the flexibility to adjust your product as your needs change.

How does Saigon Technology ensure my project stays on budget and schedule?

We work milestone by milestone, with clear deliverables, demo reviews, and weekly updates. Your Project Manager keeps everything on track by using tools like Jira, Slack, and Zoom. That means you get full visibility and on-time delivery, every step of the way.

How do you ensure project quality?

Quality is the most important at every stage. We use a multi-layered QA approach:

Manual and automated testing at every milestone
Continuous integration and code reviews
Regular demos so you can give feedback early

All work follows ISO 9001 and ISO 27001 standards, so you get software that’s stable, secure, and performs exactly as expected.

Does Saigon Technology provide warranty and support after delivery?

Yes! Every Fixed Price project comes with a warranty period to fix any post-launch issues at no extra cost. Saigon Technology offers maintenance and support packages, from updates to new feature development. This service keeps your software secure, optimized, and ready for future growth.
