You can customize text in WHMCS using the localization system. This allows you to set your own translations in your customers' languages or update the messages they see for your brand.
You can easily change the logo in emails, on generated invoices, and in the Client Area.
Delete a service to remove it entirely from your records in WHMCS. This will not remove any associated accounts from your servers.
Configure WHMCS to automatically delete data for inactive clients after they have terminated all services and a period of time has lapsed.
WHMCS's analytics tracking system only collects user activity data after an admin explicitly consents to tracking for the WHMCS installation. If an admin has previously consented to user activity tracking, you can disable the associated settings to revoke consent and stop user activity data collection.
You must disable MySQL® Strict Mode (sql_mode) to run WHMCS on your server. We recommend disabling this immediately after you finish installation.
You can disable all outgoing mail from your WHMCS installation. This allows you to test customizations, verify system changes, or perform other routine tests without sending email to customers.
