can I process multiple questionnaires at once

Multiple lists at once, one supply chain file as source

Yes, that is the entire idea behind the platform. Each customer questionnaire you upload — whether it comes from a bank, from a buyer with a sustainability question or from an insurer with a cybersecurity question — is read against the same supply chain file. If list A asks for the number of employees and list B asks for the same question in different words, then the answer for both comes from the same source. So you no longer enter separately per list what the establishment address of the company is or how revenue compares to last year; that is set once and reused.

What does remain separate per list is the confirmation. The system proposes an answer for each recognized question from the file, but you confirm each answer with yes or no — even if three lists ask the same question, you see that confirmation three times back. This is not cumbersome but a boundary the platform deliberately draws: nothing is submitted automatically and nothing is automatically approved. If a list has a question for which the file has no substantiated answer — for example one of the ten measures from Article 21(2) of the NIS2 Directive, while you have not yet implemented an ISMS according to ISO/IEC 27001 — then it remains open until you provide the answer yourself. Processing different maturity levels between customer questions mixed together works fine; the system fills in what is known and shows what is still missing, per list.

Why it works that way: one file, separate submission per portal

This follows from how the platform is set up: it builds the supply side of the chain, not the demand side. There is one supply chain file with fixed data — think of the registration number under which the enterprise is registered, in accordance with the Trade Register Act 2007, and further matters such as the VSME Basic Module of EFRAG for sustainability questions arising from the CSRD (Directive 2022/2464). Each uploaded list is checked against that one file, regardless of how many customers are asking. Submission remains separate per list, at the portal of that specific customer — the platform never logs in there itself.
