Frequently asked questions

On getting in touch, the reply, and how it works.

Six answers that cover 80% of the questions we get on this page.

How fast do you reply?

We reply to most messages within 24 business hours. For requests sent Friday evening or over the weekend, expect Monday morning. If your need is urgent (pre-sales, a mission starting soon), say so in your message and we handle those first.

Can I get a call to talk it through directly?

Yes. Most questions get answered in five lines by email, so we always start in writing. If your situation calls for a conversation (choosing between two paths, a company project, SAP career advice), we'll offer you a call slot after the first written exchange.

Do you build custom training for companies?

Yes, on the SAP modules within our scope (EWM, Supply Chain, S/4HANA, BTP, Build, PP, EAM, MES). Describe the project context, the module, the profiles to train, and the format you want (on-site, remote, hybrid). We come back with a scoped proposal and a quote.

Do you train in both French and English?

Yes. Our main learning paths are in French, but some of the content and the support are available in English. State your working language in your message and we'll tailor the answer accordingly.

I'm outside the European Union, does that change anything?

No, not on the learning side. The paths are 100% online and open to any French- or English-speaking country. On the administrative side, VAT and billing terms adapt to your status (individual, EU company, non-EU company). We spell that out case by case in the proposal.

Which coach will read my message?

XiaoXiao Liu reads the form messages first and points them to the right coach. Questions on the long learning paths and Supply Chain go to Michael Antoine. Industrial topics (PP, EAM, MES) go to Pierre Balbinot. Requests in English, German, or Mandarin stay with XiaoXiao.
