The public and client-facing areas of WHMCS are white-labelled, meaning that your visitors will not see reference to the WHMCS name.
The Starter license is provided at a discount in exchange for displaying a "Powered by WHMCompleteSolution" branding link-back to visitors.
This line can be removed by upgrading from Starter to Plus tiers or above. The process is seamless, please contact our Customer Service team to arrange the upgrade.
Pricing details of the license tier are published on our pricing page.
