Our service
Custom Software Development: From Business Process to Production
Custom software development lets you build the tool that follows your processes, rather than adapting your organization to an off-the-shelf solution. Etixio designs, develops and evolves your business applications, internal tools and SaaS platforms, integrates useful AI features into them and maintains them after go-live.
For
Organizations whose rules, workflows or integrations are not covered by off-the-shelf tools
What you get
Business application, internal tool or SaaS, with integrations, tests, deployment and documentation
Format
Fixed-price project for a defined scope, dedicated team for software that evolves over time
Timeline
An MVP generally in 6 to 10 weeks; complete business software over several months
What we build
A scope tied to your business.
Custom development becomes relevant when the rules, user journeys or integrations of your business are not properly covered by available tools. It may be an internal application, a portal or a commercial product. We examine what is worth developing and what can rely on an existing service.
Architecture & integrations
Connect interfaces, application logic and data to your organization’s tools.
Quality & maintenance
Test user journeys, organize production releases and prepare the next iterations.
- Functional and technical scoping: workshops, user stories, prioritization and architecture
- UX/UI design: user journeys, mockups and interactive prototypes
- Development: front-end, back-end, APIs and databases
- Integrations: ERP, CRM, SSO, payment, data and internal tools
- Security and quality: automated tests, code reviews, continuous integration
- Deployment and maintenance: monitoring, support and enhancements
For which needs
Why choose custom software development?
An off-the-shelf solution is faster to deploy at first, but it imposes its own way of working. Custom software becomes strategic when your rules, your integrations or your product are what set you apart.
Digitize a business process
Back office, finance, HR, logistics or compliance move from manual workflows to a tool that applies your rules, logs operations and organizes approvals.
Replace spreadsheets or an aging application
When Excel or an old tool becomes a source of errors and dependency, maintainable software takes over the data and the usage without losing what works.
Unify your information system
Custom integrations connect ERP, CRM, BI tools and internal applications to eliminate duplicate data entry.
Build software you can sell
A SaaS product or software sold to your customers often starts with an MVP, then evolves into a solution ready to scale.
Add AI where it is useful
Search across your documents, data extraction, summarization or an assistant embedded in your screens, with the same security and testing rules as the rest of the software.
From work to deliverables
How the engagement unfolds.
The design describes the users, the business rules and the data exchanges. We build the first features end to end, then test them against real usage. Tests and demos accompany each stage. Configurations, access and documentation are prepared for go-live and for handover to your team.
What your team receives
- User journeys and architecture
- Source code and tests
- Deployment and documentation
Deliver continuously, without sacrificing quality
Our custom software development method.
Scoping and product vision
Process mapping, backlog, risks and an estimate with its assumptions. See IT project scoping.
Design
User journeys, prototype, architecture and delivery plan.
Iterative development
Sprints, regular demos and documented code, with systematic code reviews.
Quality
A testing strategy proportionate to risk, unit, integration and regression tests, acceptance criteria.
Deployment and maintenance
Continuous integration and deployment, environments, a production release plan, then corrective, preventive and evolutionary maintenance.
Our technology stack
The technologies behind your custom software.
The choice depends on the type of software, your information system, the volumes to process, the integrations and the security constraints. We select a stack suited to the context rather than a technology imposed by default.
Languages
JavaScript and TypeScript, Python, PHP, Java, .NET and Go, depending on the nature of the processing and the existing systems.
Frameworks
React, Angular and Vue.js on the front end; Node.js, Symfony and Laravel on the server side.
DevOps
Docker, GitHub and GitLab, continuous integration and deployment pipelines.
Cloud, data and AI
AWS or dedicated private cloud, data and BI, AI model integration, automation and performance optimization.
Business software and AI
Integrating AI into custom business software.
Business software concentrates documents, files and rules: that is often where AI is most useful. We add specific features — finding information, extracting fields from an incoming document, preparing a summary, assisting data entry — and treat them as software components, with access rights, logs, evaluations and cost tracking.
For a SaaS product, see our AI features for your product. We also take over AI prototypes and bring them all the way to production. See our AI solutions for businesses.
The choices that matter
The points to decide with your team.
The budget must include integrations, data migration and operations. A first version can focus on the priority user journeys without trying to immediately replicate every tool in place. Architecture choices are tied to foreseeable changes and to maintenance capabilities.
The collaboration framework
Preparing the first conversation.
You can present how things currently work, the users involved and the difficulties you face. The documents, examples and access required are specified afterwards, depending on the chosen scope. The first objective is to understand the work to be done and the dependencies that may affect how it unfolds.
A structured team to deliver. Depending on the software, the team brings together front-end, back-end or full-stack development, QA, DevOps, data and product management, supervised by a tech lead. Our French-speaking engineers in Madagascar and Mauritius work with a 1 to 3 hour time difference from Paris, within your tools and rituals.
A defined scope is delivered as a fixed-price project; software that evolves over time is entrusted to a dedicated team.
Frequently asked questions
Custom software development: your questions.
What is the difference between custom software and an off-the-shelf solution?
Custom software is designed around your processes, your users and your technical constraints. An off-the-shelf solution imposes a predefined way of working; it is faster and cheaper to start with, but shows its limits when needs are specific or integrations complex. The choice depends on the level of customization, the budget, the timeline and the strategic role of the software.
How do you define the architecture of custom software?
During scoping, based on functional needs, the number of users, data volumes, security requirements and foreseeable changes. We take into account your information system, integrations and hosting constraints, without unnecessary complexity. Key decisions are documented.
How long does it take to deliver an MVP?
An MVP can generally be delivered in 6 to 10 weeks when the need is clear and the scope is focused on the essentials. The timeline depends on business complexity, integrations, expected design and security constraints. More complete business software is built over several months, with incremental deliveries.
Can you take over existing software?
Yes, whether it was developed in-house or by another provider. The takeover starts with a technical audit of the code, architecture, dependencies, security and deployment. We then decide whether to stabilize, refactor, modernize or rebuild certain parts, with a prioritized action plan.
How do you ensure software quality?
Through acceptance criteria defined upfront, code reviews, tests suited to the level of risk (unit, functional, integration, regression) and regular demos. Continuous integration automates checks and makes production releases more reliable.
Can you integrate AI into our business software?
Yes. Document search, extraction, summarization or an assistant are added as services of the software, with the same security, testing and monitoring requirements. We can also take over an existing AI POC to make it usable in production.
Do you handle maintenance and enhancements?
Yes. Corrective, preventive and evolutionary maintenance, security updates, performance monitoring and new features. The support setup is defined according to the criticality of the application and the expected response times.
Who owns the source code?
You do. The code, configurations, access and documentation for the delivered scope are handed over to you so that your team can take over the software.
