TL;DR: Custom software development becomes necessary when generic tools limit your growth, when your business has specific rules, or when you need to integrate several systems in real time. Common types include business web applications, SaaS platforms and APIs/microservices, with modern stacks (Node.js, Python, React, PostgreSQL, Docker).
Your business uses a patchwork of spreadsheets, generic SaaS and manual processes to run operations? At a certain growth stage, standard tools become a brake: they don’t adapt to your business specifics, generate double entry and don’t talk to each other.
This is where custom software development makes full sense.
When custom becomes necessary
Your current tools limit you
You’ve pushed Excel, Notion or your CRM to their limits. Workarounds pile up, errors multiply, and the team spends more time bypassing tool limits than working.
Your business has specific rules
Some sectors (logistics, healthcare, finance, industry, real estate) have complex business rules that no generic tool covers properly. Custom allows you to code exactly the logic you need.
You need to integrate multiple systems
ERP, CRM, accounting, e-commerce platform, field tools — when these systems need to talk in real time, custom development with dedicated APIs is often the only reliable solution.
You want a competitive edge
A high-performing, unique internal tool is an advantage your competitors can’t copy. It encodes your business know-how in software.
Types of custom software
Business web applications
Accessible from a browser, deployed in the cloud or on-premise. Custom CRM, adapted ERP, internal management platform, customer/supplier portal.
SaaS platforms
You have a product idea? Developing a SaaS (Software as a Service) platform lets you commercialise it with a subscription model. Multi-tenant architecture, user management, integrated billing.
APIs and microservices
Sometimes the need isn’t an interface but an engine: a service that processes data, orchestrates flows, or exposes business logic via API to be consumed by other applications.
Migration and transformation tools
Migrating a legacy to a modern architecture, refactoring a monolith into microservices, transforming a manual process into an automated pipeline.
Our development method
Architecture first
Before coding, we design the architecture: technical stack choice, data modelling, API design, deployment strategy. Good architecture is the foundation of maintainable and scalable software.
Modern technical stack
- Backend: Node.js, Python (FastAPI, Django), Go
- Frontend: React, Next.js, Astro
- Database: PostgreSQL, MongoDB, Redis
- Infrastructure: Docker, Kubernetes, CI/CD (GitHub Actions)
- Cloud: AWS, GCP, OVHcloud (sovereignty)
Iterative development
Sprints of 1-2 weeks with regular deliveries. Each iteration produces a functional version. The client tests, validates and continuously adjusts priorities.
Quality and testing
Unit tests, integration tests, systematic code reviews. The code is clean, documented and versioned. No accumulated technical debt.
Deployment and DevOps
Automated CI/CD: every merge on the main branch triggers tests, build and deployment. Zero manual intervention, zero downtime.
Pitfalls to avoid
- Over-specifying upfront: a 200-page spec written before the first line of code is a recipe for failure. Favour iteration.
- Underestimating maintenance: software lives. You need to plan evolutions, security updates, user support.
- Choosing the wrong stack: technology must be chosen by need, not by trends. A bad technical choice haunts you for years.
- Forgetting security: authentication, encryption, rights management, injection protection — security is thought about from day 1.
