The Bulk Subdomain Manager is a comprehensive WHMCS addon designed to streamline the management of domains and subdomains across multiple cPanel hosting packages. With this module, administrators can efficiently add new domains and assign them to one or more WHMCS products in bulk, eliminating repetitive manual tasks and saving time.

This powerful module allows you to manage packages per domain, view all assigned subdomains at a glance, and automatically update the products subdomain field in WHMCS. Deleting a domain will automatically remove its associated subdomains from the relevant products, keeping your hosting setup organized and consistent.

Integrated seamlessly into the WHMCS admin interface, the Bulk Subdomain Manager uses modern Bootstrap 5 modals to provide a smooth, intuitive user experience. It supports multiple domains and packages, making it ideal for hosting providers who manage large numbers of domains. By automating subdomain assignments and providing a clear overview of domain-package relationships, this module reduces errors, improves workflow, and enhances overall efficiency.
