## Explanation of Key Terms

### WHM (Web Host Manager)

Admin panel for resellers. From WHM you create packages, cPanel accounts, and monitor resources. Read the introduction: [What is cPanel/WHM Reseller?](/en/what-is-cpanel-whm-reseller-hosting-complete-guide-for-beginners/).

### cPanel

Panel for clients (website owners). Manage files, databases, email, domains, SSL—see [cPanel](/en/complete-cpanel-guide-for-beginners/) Guide and [What is cPanel](/en/introduction-to-cpanel-what-it-is-and-how-to-access-it/).

### White Label & Private Nameservers

Your brand appears as a provider; use **private nameserver** (e.g. `ns1.brandanda.com`). Next: [Nameserver & DNS](/en/what-is-nameserver-dns/).

### WHMCS (Billing & Automation)

Software for billing automation, cPanel provisioning, suspend/unsuspend, renewal notifications. Alternatives exist, but WHMCS is most common in the cPanel/WHM ecosystem.

### Overselling

Selling logical allocations above the real average capacity usage. Safe if:

* There is a clear **fair-use** policy
* Monitoring CPU/RAM/IO running
* Avoid aggressive allocation without usage data

### CloudLinux / LVE Limits (CPU/RAM/IO/EP/Inodes)

Technical limits per account to maintain shared server stability. Educate clients if they are approaching the limit so that they can optimize or upgrade. See also: [cPanel](/en/email-account-settings-in-cpanel-complete-guide/) Email for IP reputation impact & email limits.

### Backup & Security

Understand **backup retention** (daily/weekly), ease of restore, as well as DDoS protection and security like Imunify 360. See: [Backup cPanel](/en/backup-website-files-in-cpanel-complete-guide/) and [Install SSL cPanel](/en/installing-ssl-in-cpanel-complete-guide/).

### SLA & Uptime

Read the availability promise (e.g. 99.9%) along with compensation and exclusions. Compare providers at: [Reseller Hosting Directory](/en/reseller-hosting/) Hosting Reseller Directory.

Tip: unify client onboarding SOPs (cPanel access, email, backup, SSL) so that support load remains under control and the client experience is consistent.
