do I have to upload it myself at my customer or does the system do that

No, you submit it yourself

The system does not automatically fill in your customer's portal and does not submit anything on your behalf. It recognizes the questions on the list you upload, retrieves the corresponding answers from your chain file and prepares them. You review the answers and confirm each answer with yes or no. After that, you go to your customer's portal yourself and enter it, or you upload the file you have compiled. There is no connection with third-party portals and no one logs in for you anywhere.

This is intentional. A list from a bank often asks for different supporting documents than a list on the ten measures of Article 21 of the NIS2 Directive, and with a CSRD questionnaire, it may involve figures from the VSME baseline module that only you can interpret in relation to that specific customer. You have the final say over what goes to a customer. This also applies to sensitive parts: whether you share details about in which countries the enterprise has establishments or about or whether the undertaking deploys AI systems within its service delivery, you decide per answer, with the confidentiality button.

Why there is no connection with customer portals

This follows directly from how the platform is set up: it serves only the response side of the chain, not the requesting side. Nothing is certified, nothing is assessed and no one here reads a completed list along. The system never logs in to a third-party portal — that would also not fit with a service that explicitly makes no statements on your behalf. The confirmation per answer (yes or no) is therefore not a formality, but the moment when you make the answer your own answer, before it goes to the customer. The same logic applies to basic data such as the establishment address of the company: the file provides it, you confirm it, you submit it.
