Customer portal — user guide

Signing in​

Go to your supplier's portal (e.g. https://klant.example.nl or the link they sent you) and sign in with your email and password. If two-factor authentication is required you will be asked to set it up with an authenticator app (Google Authenticator, Authy, …) and then enter a 6-digit code.

Forgot your password? Use Wachtwoord vergeten? / Forgotten your password? — you will receive a reset link by email (valid 30 minutes).

Viewing invoices, contracts and orders​

The Documents tab shows your invoices, contracts and orders. Use Download to open a document; the link is short-lived for your security.

Submitting and following up requests​

Under Requests you can:

  • See the status of your requests (e.g. Wachten op uw reactie / Awaiting your reply).
  • Open a request to read the messages and reply.
  • Submit a new request with a subject, message and (optional) attachments (max 25 MB per file).

Updating your details​

Under My details you can change your name, phone, address, language and (for business accounts) job title. Changing your email sends a verification link to the new address — your login stays the same until you confirm it.

Sharing access (business accounts)​

Under Shared access you can let a colleague see your invoices/contracts or submit requests on your behalf, for a chosen period, and revoke it at any time.

Privacy and your data​

Under Privacy you can:

  • Request my data — download a machine-readable copy of everything the portal holds about you (AVG/GDPR Art. 15).
  • Close my account — confirmed by an email link. Closing is permanent.

Session timeout​

For your security your session expires after a period of inactivity. A warning appears 60 seconds before expiry with Extend session and Log out buttons.
