The questions we receive the most often.

Three offers with visible starting prices: AI integration from €1,500, Site with an AI chatbot from €2,500, Business app with AI €7,500 to €15,000. Outside these tiers (large project, overhaul of an existing product, unusual integration), we scope it on a free discovery call and I send a detailed quote within 24h. Payment in two steps: 30% on signature, 70% on delivery, or by milestones for larger projects.

Detailed quote within 24h after your brief or the discovery call. Site with an AI chatbot: 5 to 7 days. Business app with AI integration: 15 to 25 days depending on scope (homegrown ERP, Access database, legacy intranet to augment). And throughout the project, regular progress updates: you always know where things stand.

No. In 30 minutes, I look at your need and your existing setup, then tell you honestly which tier fits your case, at what budget, and whether I am the right profile for the job. If it turns out to be a poor fit, you leave with an honest opinion and concrete pointers, and that's it. Prefer writing? The contact form plays the same role: written brief, personal reply within 24h. And to examine a product already in production in depth, there is the code audit (1 to 3 days, €1,000 to €3,000).

On-site around Ebersviller: Thionville, Metz, Luxembourg. Remotely for the rest of France and Europe. Most projects actually run entirely remote.

The ones your team (or the next one) can maintain: your current stack is respected. If you already have a technology that works, I build on it; if we start from scratch, we choose together, and you only pay for technology your project actually needs. Backend: Node.js and relational databases. Infrastructure: containers, CI/CD, verified backups. AI: European cloud providers, with your data excluded from model training, by contract. Modern and stable technologies only, in LTS versions, with mainstream, actively maintained dependencies.

At Willsofts, AI is part of the project from the brief. The chatbot on this site (bottom right of every page) is one example: custom-built, it answers from the site's real content. Search across your documents, business agents (qualification, appointment booking), internal chatbots. Your data stays yours: clear contracts, no training on your content, transparent usage-based cost, GDPR compliant. Limits (hallucinations, costs) are laid out in black and white from the scoping stage.

Yes, in every project: written documentation, training (video or in person depending on the need), a 2h team workshop on Business app with AI projects, and 30 days of support after delivery. My job is also to make you autonomous on what you ordered: you must be able to maintain it, adjust it, or change providers and keep everything.

You, if you wish: documentation and workshop included, you stay in control. Or me, on a monthly plan of €200 to €500: monitoring, updates, small adjustments, chatbot follow-up. À la carte, month to month.

Three concrete guarantees. (1) Reversibility is built in from the start: standard technologies, complete documentation, and everything you own stays with you (code, content, access). Any provider can take over. (2) An established activity: French trademark registered since 2023, and I write code every day, for my clients and on my own products. (3) Knowledge transfer is included: at delivery, you know how to run what you ordered.

No. Every line of code, every configuration, every explanation comes from me. If a project calls for skills outside my scope (high-end art direction, SEO copywriting), I point you to trusted partners, and you contract directly with them, at their own rates, fully transparent.
