does supplia itself log in to my customer's purchasing portal

No, you submit it yourself in your customer's portal

Supplia does not log in to your customer's procurement portal and does not submit anything on your behalf. The system recognizes the questions on the list you upload yourself, and completes the answers from your supply chain file. For each answer you confirm with yes or no. After that you go to your customer's portal yourself and enter the answers there, or you upload the file that the portal expects. That last step is outside Supplia.

This applies to every type of portal: a sustainability questionnaire based on the VSME baseline module, a security questionnaire that refers to the ten measures of Article 21(2) of Directive (EU) 2022/2555 or to the control measures of ISO/IEC 27001 Annex A, or a list from a bank or insurer. The distinction is always the same: Supplia builds the answer, you assess it, and your customer's portal remains an environment where only you log in yourself. Questions that frequently appear on such lists — the company's registration number, the number of employees, or or whether there is an ISO 9001 certificate — come from your supply chain file, but you enter the data in the portal yourself.

Why there is no connection with customer portals

This does not follow from a single provision, but from how Supplia is set up: the platform serves exclusively the supply side of the chain and therefore does not require access to the systems of the requesting party. There is no technical connection with the portals where customers manage their questionnaires — whether it is a CSRD report based on Directive (EU) 2022/2464, a NIS2 questionnaire, or a bank's own format. The result is that entering and submitting in your customer's portal always remains an action that you yourself carry out under your own login credentials.
