Custom software & automation
Your teams deserve better
than 3 hours of spreadsheets a day.
We design custom software and automations that fit into your daily workflow. No forced migration. No endless training.
What you're losing
Every month without automation costs you.
Not hypotheses. Real hours, measurable errors, decisions made on stale data.
lost per employee, per week
Endless re-entry
Copy-pasting between Excel, ERP, email, CRM. Every re-entry is an opportunity for error and an hour you'll never get back.

Errors that pile up
Duplicates, wrong invoiced prices, incorrect stock. Anomalies that cost in fixes, credit notes and credibility.

Decisions in the fog
Your dashboards are updated Monday morning. Your strategic decisions rest on figures from two days ago.

The invisible turnover
Your best people leave when their day boils down to filling forms and aligning columns.
The fundamentals
What it means, concretely.
Free your teams from low-value tasks.
Automation is a program that takes a repetitive, predictable task and does it instead of your employee. Not robots. Not job cuts. Tools that absorb the grunt work so your teams focus on what matters.
- Client follow-ups sent automatically
- Invoices generated on every order
- Real-time stock alerts
- Weekly reports without effort
A tool that speaks your language.
Off-the-shelf software comes with 90% of features you don't need and 10% missing ones you patch with Excel. Custom software is exactly your real processes in a tool your teams actually want to use.

2-3 wksWe translate your needs into clickable prototypes you can test immediately. Concrete screens, validated by your teams before development starts.
Interactive prototypes, user validation
Build
VariableWe develop in two-week cycles. Each sprint delivers a working version you can touch. You stay in control at every step.
Short cycles, regular demos, continuous adjustments
Deploy
1-2 wksGo-live is carefully orchestrated. We train your teams on your tool, with your real data. No slides. Hands in the tool.

Your questions
What everyone asks before signing.
Every project is unique. We offer a 30-min call to understand your need and give you a realistic range. Custom software costs more upfront than a SaaS, and often less over 3 years once licenses, workarounds and lost productivity are factored in.
That's normal, and it's our job to build it with you. The audit step is exactly for that. You have concrete problems, not specifications. We start there.
Perfect. Our software is designed to be picked up immediately, with no technical training. We train your teams on-site with your real data, not manuals.
A first visible prototype in 3-4 weeks. The full version depends on project complexity. We work in short cycles with regular demos — not a single delivery after 6 months of development in the dark.
Good news: we don't need another one. We connect to your ERP via API to automate what it doesn't do natively. Your investment stays intact — we enrich it.
Resistance rarely comes from the technology — it comes from bad design. Our tools are designed with end users, not for them. Every screen is validated by the people who will use it before we build.
Going further
Technical & business questions.
Most SMEs don't measure this cost. For an employee spending 2h/day on manual tasks, that's roughly 10h/week — 40h/month. At €25/hour, that's €1,000 per month per employee in uncreated value. Multiply by the number of people affected.
The simple rule: if a task is repetitive, predictable and based on structured data, it's automatable. Follow-ups, reconciliations, document sending, notifications, database updates — all these cases are handled effectively by automation.
If a SaaS covers 80% of your need without workarounds, use it. If you're constantly working around its limits with Excel, paying for features you don't need, or if your process is a competitive advantage to protect, custom is the right answer.
Yes — that's actually our default approach. We connect to your existing tools via API or native connectors. Your ERP stays your ERP. We automate the flows between it and your other tools, fill the gaps, build what's missing.
