Hi there,
Thank you for reaching out to us.
To connect a Stripe Connect account and receive payments, the vendor can follow these steps from their dashboard:
Dashboard → Store Settings → Billing
From there, they simply need to choose Stripe Connect from the dropdown and complete the connection process.
For detailed guidance, please refer to our documentation here https://multivendorx.com/docs/knowledgebase/stripe-connect/.
Now may I know where your vendor is getting the message “Connect your account to Stripe,” once we will have the details we will be able to assist you further.
