Yes. You can pause your supplier sales account yourself, or stop selling on individual listings.
To pause the whole account, open preferences, then company, and choose pause account:
While paused, your listings are hidden from the storefront and search until you resume account. Login and the Supplier API still work. Open orders still need fulfilling, and new orders can still arrive during a pause. Pause does not automatically stop payouts. Public verified-supplier listing needs an active sales account, so a paused account does not qualify.
As an alternative, leave the account active and deactivate specific listings in the portal, via import status, or with listings write on the Supplier API:
Supplier support for other account questions: partners@ordentic.com. You do not need that address to pause.
