Fixed-Price IT Project: A Product Delivered on a Committed Scope

In a fixed-price IT project, Etixio commits to a result: software, a product or an AI solution delivered on a scope, milestones and acceptance criteria defined together. We scope, build, test and release to production, including when it means taking an AI POC and turning it into a service you can run.

For

Organizations with a defined need that want a result without managing a technical team themselves

What you get

Application, upgrade, AI project or AI POC takeover delivered to production, with code and documentation

Team

An Etixio tech lead and a project manager; engineers in Madagascar and Mauritius

Duration

From a few weeks for a limited scope to several months for a more substantial application

What we deliver

A scope tied to your business.

A fixed-price engagement is a commitment on a defined delivery scope. It fits when features, integrations and acceptance criteria can be described with enough precision. Scoping is used to prepare this agreement and to separate out the assumptions still to be cleared.

Define the deliverables

Describe the features, integrations and acceptance criteria included in the scope.

Organize the stages

Share the milestones, expected sign-offs and each party’s responsibilities.

Manage changes

Assess the impact of a change before adding it to the scope, budget and schedule.

What we deliver at a fixed price

Complete projects, from design to go-live.

Fixed price is not limited to small work packages. It suits any project whose expected result can be described and verified, and we take charge of the entire delivery.

A product or an application

Web or mobile application, business software, SaaS platform, customer portal or internal tool, delivered with its code, tests, documentation and production release. See custom software development.

An enhancement or a redesign

A new module, a redesigned user journey, modernization of an existing application or a migration, with a clearly bounded scope and a prepared cutover.

An AI project

An assistant or agent connected to your tools, or an AI feature added to your product (document search, extraction, summarization), with the evaluations and monitoring needed for production. See our enterprise AI solutions and our AI agents and chatbots.

Taking over an AI POC

Your prototype works in a demo. We take over the code, the data and the model choices, then add authentication, permissions, error handling, monitoring and cost control until it becomes a service you can run.

Why fixed price

Why choose a fixed-price IT project?

A fixed-price IT project fits when the need is defined and you want a clear framework for budget, timelines and deliverables, without managing a technical team yourself.

A scope defined upfront

Prioritized features, specifications and acceptance criteria are approved before the commitment. This framework limits drift and secures execution.

A defined budget

The estimate is based on identified deliverables and an approved scope. You know what is included, what is not, and how a new request is handled.

A structured schedule

Intermediate milestones, incremental deliveries and formal sign-offs let you track progress on tangible results.

Accountable project management

A project manager coordinates progress tracking and is accountable for meeting commitments; the Etixio tech lead owns the architecture and is accountable for the quality of what is delivered. You have clear points of contact, not a team to manage.

From work to deliverables

How the engagement unfolds.

We describe the deliverables, milestones and required sign-offs. Demos provide visibility during development, then acceptance testing checks the agreed criteria. Any change is assessed before it is added, to make its effects on the work, the schedule and the budget explicit.

Scoping

Needs analysis, prioritization, and definition of deliverables and acceptance criteria. See IT project scoping.

Commitment

Approved budget, defined milestones, structured schedule. An IT project estimate can come before this step.

Build

Architecture, development, code reviews, automated tests and intermediate deliveries with demos.

Acceptance testing

Functional acceptance testing and verification of the agreed acceptance criteria.

Go-live

Deployment, handover of documentation and post-delivery support, followed by maintenance if you wish.

What your team receives

  • Contracted scope
  • sign-off milestones
  • deliverables and acceptance testing
  • code, documentation and deployment procedures

The project team

A complete team, managed for your project.

For each fixed-price project, we put together a delivery team coordinated by a project manager and led by an Etixio tech lead. The tech lead owns the architecture and technical choices, reviews the code, organizes the team’s day-to-day work, remains your technical point of contact and ensures continuity (documentation, handover). You set the priorities and approve the deliverables; the tech lead is accountable for the quality of what is delivered.

Our engineers work from Madagascar and Mauritius, with a 1 to 3-hour time difference from Paris. Depending on the project, the team brings together front-end, back-end or full-stack development, QA, DevOps, data and AI, and product management. It follows our engineering standard:

Ownership and integration

You stay in control: your code, your access, your tools.

Everything remains yours: source code and repositories, access and accounts, tools, data and documentation. On a fixed-price project too, our teams work inside your environment (your Git repositories, your ticketing tool, your environments, your security rules), and you can take back control at any time or hand the next phase to another team.

Technologies

A stack chosen during scoping.

In fixed-price development, technologies are chosen during scoping based on your business constraints, your existing environment and your plans for future growth. We favor proven technologies that your team will be able to take over.

Languages

JavaScript and TypeScript, Python, PHP, Java and .NET.

Frameworks

React and Angular on the front end, Node.js, Symfony and Laravel on the server side.

DevOps

Docker, GitHub or GitLab, continuous integration and deployment to automate testing and production releases.

Cloud & AI

Cloud hosting, process automation, integration of AI models (OpenAI, Claude, Gemini) and agents connected to your tools.

The right model

Fixed price, dedicated team or targeted expertise: which model to choose?

Fixed-price IT project

A defined scope, an approved budget and a commitment on deliverables. Best when the need is clear and you want to secure timeline, budget and result without managing a technical team.

Dedicated team

A team that works exclusively on your product over time and builds up its knowledge. Best when the roadmap evolves continuously. See the dedicated IT team.

Targeted expertise

An Etixio engineer, guided by our tech lead, handles a specific technical topic within your team for a limited period. See offshore IT staffing.

A project delivered at a fixed price can then be maintained and extended by a dedicated team that takes over the knowledge gained.

The choices that matter

The points to decide with your team.

A fixed price does not remove the need for business involvement. The access, content and sign-offs expected from the client are identified. If the need changes significantly or remains exploratory, an initial scoping phase or incremental delivery may provide a better-suited framework.

For an AI project, acceptance criteria also cover the quality of responses, measured on an agreed evaluation set, and operating conditions (response time, costs, logging). Each industry adds its own compliance, security or integration constraints, which are taken into account from scoping onward.

How we work together

Preparing the first conversation.

You can walk us through how things currently work, the users involved and the difficulties you face. The documents, examples and access needed are specified afterwards, depending on the agreed scope. The first goal is to understand the work to be done and the dependencies that may affect how it unfolds.

Frequently asked questions

Fixed-price IT project: your questions.

What is a fixed-price IT project?

A model in which the scope, deliverables, budget and timelines are defined during scoping, with acceptance criteria approved upfront. Unlike time & materials, you buy a result, not time. At Etixio, we manage the project end to end from France, with an Etixio tech lead and our engineers in Madagascar and Mauritius.

What is the difference between a fixed-price project and time & materials?

With a fixed price, the commitment covers identified deliverables, with a defined scope, budget and timeline. With time & materials, you pay for time on an evolving scope. Fixed price suits a structured need; time & materials suits an open or rapidly changing scope.

How is the scope of a scoped project defined?

Through scoping workshops that analyze business goals, technical constraints and priorities. Features are formalized, prioritized and turned into deliverables with precise acceptance criteria, which form the basis of the estimate.

What happens if the need changes during the project?

An impact analysis assesses the adjustments needed to the budget and schedule. The change goes through additional scoping and formal approval before it is added, which keeps the project under control while remaining flexible.

How is the budget for fixed-price development built?

From the scope approved during scoping. Each feature and each deliverable is analyzed to estimate the delivery effort. Any request outside the initial scope is assessed separately.

What kinds of projects are suited to a fixed price?

Projects with a defined need and formalized objectives, such as building or evolving applications, business platforms, internal tools or AI solutions. Fixed price fits when you want to secure budget, schedule and result without directly managing a technical team.

Can an AI project or an AI POC takeover be done at a fixed price?

Yes, if the expected result can be described and verified. Together we set an evaluation set and acceptance criteria (response quality, response time, costs, security), then we deliver the service to production. When the achievable quality is uncertain, an initial prototype or scoping phase comes before committing to the rest.

Who owns the code and access on a fixed-price project?

You do. Source code, repositories, access, accounts, data and documentation remain yours. We work in your repositories and tools, and the documentation is kept up to date with each release, so your team or another one can take over the software.

How long does a fixed-price IT project take?

From a few weeks for a limited scope to several months for a more substantial application. The schedule is set upfront, with intermediate milestones to track progress.

How is it different from a dedicated team?

A fixed price commits to a scope, budget and deliverables defined at the outset. A dedicated team works exclusively on your product over time, with priorities that evolve with your roadmap. Fixed price suits a well-defined need; a dedicated team suits ongoing delivery capacity.
