We apply a transparent and healthy collaboration model: you remain the owner of your infrastructure.

In practice, I help you create your own accounts on the necessary services (Supabase for the database, Vercel for hosting), you add your credit card. You then add me as a collaborator with the necessary permissions so I can deploy and manage your application.

Why this model?

• ✅ You control your costs: direct billing, no intermediary
• ✅ No hidden fees: you only pay for what you consume (sometimes €0 depending on your needs)
• ✅ Total scalability: your infrastructure grows with your needs
• ✅ Guaranteed ownership: your data and project are 100% yours

On my side, I only bill you for development and maintenance. The technical effort on your part? Simply creating these accounts in a few minutes (I guide you step by step). After that, I handle everything else: deployment, configuration, production release.

To ensure a clear, secure, and fair working framework for both parties, I operate with a deposit system and milestone-based payments.
This is the most reliable and widely used model for custom software development projects.

🔐 The principle

The project is divided into key stages (milestones).
Each validated stage triggers a payment, which ensures:

clear mutual commitment,

visibility into project progress,

financial security throughout the project.

📐 Typical billing structure

30–50% deposit upon signing the proposal
→ contractual commitment and project kickoff

Intermediate payments at each validated milestone
→ progressive delivery and continuous control

Final balance before full delivery or production deployment

💡 Concrete example

For a project with a total budget of €10,000:

40% upon signing → €4,000

30% after delivery of the MVP / first version → €3,000

30% before final delivery → €3,000

⏸️ Important

Work continues only after payment of the invoice related to the previous milestone.
This ensures a smooth project with no blockers or misunderstandings.

To ensure the quality and longevity of your application, our process includes one round of minor changes (bug fixes or cosmetic adjustments) free of charge, within 30 days of delivery.

After this period, the following rates apply:

• Minor changes (e.g., text updates, color changes, button adjustments): €50 per request (billed individually).
• New features or major changes (e.g., adding a module, redesigning a page): custom quote (starting from €200, depending on complexity).
• Urgent requests (turnaround < 48 hours): 30% surcharge on the base rate.

For dynamic showcase websites, yes, absolutely. Each project is delivered with a custom-built admin interface.
