Frequently asked questions

Why offer optional validation?

To avoid spending €7,000 to €20,000 on a project that won't work. The audit tests whether AI correctly answers your business questions with your real data. You receive an honest Go/No-Go recommendation + a precise estimate. If it's "No-Go", you'll have invested €2,000 for an informed decision rather than the full budget.

Do the prices include hosting and APIs?

No, hosting and API costs (OpenAI, Anthropic, etc.) are at your expense. I provide a detailed estimate of monthly costs (generally €50-300/month depending on usage) and help you optimize these costs.

Can I pay in installments?

Yes! Payment in 3 installments: 30% at start, 40% mid-way, 30% at delivery.

What happens after delivery?

You receive all source code, complete documentation, and post-launch support (duration according to offer: 2 weeks to 1 month). After that, you're autonomous or you can subscribe to monthly maintenance (€1,500/month).

Can I modify the agent after delivery?

Absolutely! You own the code. You can modify it yourself (technical documentation provided), ask me for evolutions (hourly rate or fixed price), or have another developer work on it.
