Concrete examples of custom software to transform your business
Why discovering concrete examples can make all the difference
When you’re considering digitalising your processes or automating certain tasks, it’s easy to get lost in acronyms, features and abstract promises. Looking at real cases of custom software developed for companies similar to yours is one of the most effective ways to understand what can truly be achieved — and how it can transform your day-to-day professional life.
Here are some practical examples of custom software designed to meet real needs.
Practical examples of custom software
📌 Multi-site commercial CRM
A client wanted to centralise the management of their sales opportunities spread across multiple branches. We developed a personalised CRM with tailored workflows for each user, sales phase tracking, automated reports and integrated electronic signatures. Result: a better coordinated sales team and an increase in conversion rates.
📌 Intranet with document management for a consulting firm
A consulting firm approached us to improve communication with their clients. We designed a secure intranet allowing access to tax documents, automatic alerts for deadlines and centralised exchanges in a single space.
📌 Offline time-tracking mobile app for construction sites
For a company working on sites without network coverage, we developed a mobile time-tracking app with geolocation and digital signature, working even offline. As soon as the connection is restored, data synchronises automatically.
📌 Internal technical support platform
We designed an internal solution to classify incidents, automatically assign them to the right people and generate predefined responses. Thanks to this tool, the company reduced resolution times and improved internal satisfaction.
📌 Shift planning system for medical centres
We developed a custom application to manage schedules, replacements, leave and on-call duties. Integrated with the existing HR system, the solution allows employees to consult their timetable in real time, from any device.
📌 Order portal for distributors
A company wanted their distributors to be able to place orders online, without going through the sales team. We created a private platform with a personalised catalogue, specific pricing and conditions tailored to each client.
📌 Integration between Factorial and Business Central
For a client already using both tools, we developed a full integration synchronising staff data, absences and costs between Factorial and the Business Central ERP. This automation eliminated numerous manual tasks in their HR management.

FAQ on custom software
What is the best example of custom software?

When should you consider building custom software?
When your current tools are holding you back, when you’re constantly repeating manual tasks, or when you’ve tried several solutions without finding one that truly fits the way you work.
Is it better to adapt existing software or start from scratch?
It depends on your situation. In some cases, it’s possible to integrate or extend what already exists; in others, it’s better to build on a solid, scalable foundation to maintain full control over your processes.
