how does payment work do I pay per completed questionnaire or a fixed amount per year

No payment per questionnaire

Supplia does not charge per completed list. You pay a fixed amount per year for access to your supply chain file, regardless of how many questionnaires you complete with it. Whether you receive three or thirty lists per year — from banks, insurers or customers with a CSRD question as referred to in Directive (EU) 2022/2464 — the amount does not change with that number.

This is a deliberate choice, not incidental. A price per list would make you hesitate to also complete that small, tedious questionnaire from a mid-sized customer, and that is precisely the behaviour the platform does not want to reward. The question why the bank asks completely different questions than the insurer when it is about the same company, illustrates this: the same file serves dozens of formats, and that only works if use itself is not slowed down by price.

Justification: the file, not the list, is the product

This does not follow from a legal article but from how the supply chain file is structured: it consolidates data that is already fixed anyway, such as the Trade Register Act 2007 requires for the basic data of your company, and the client due diligence that banks and other institutions must carry out under the Money Laundering and Terrorist Financing (Prevention) Act. That data does not change per questionnaire, only the format in which a customer wants to see it. For example, who are the ultimate beneficial owners of the company enters the file once, and that answer is then reused in every list in which it is requested — without paying for it each time.
