Based on my research, it appears that you cannot provision domains on a single Plesk server while using WHMCS because WHMCS cannot be installed on the same server where you want to provision domains. Does this imply that I must purchase two separate Plesk licenses—one for the WHMCS server and another for provisioning? Unlike cPanel, which doesn't impose this restriction, it may seem inefficient to have an entire Plesk installation solely for a single WHMCS management instance. Am I interpreting this correctly, or is there a different understanding?
