WHAT A PACKAGE IS
A template of limits applied when creating an account: disk, bandwidth, databases, mailboxes, subdomains, addon domains.
CREATING ONE
WHM > Packages > Add a Package. Set the limits and save.
Create one per tier you sell.
WHY USE PACKAGES RATHER THAN SETTING LIMITS PER ACCOUNT
Consistency. Every client on the same plan gets the same limits.
Changing the package changes every account on it, which is how you adjust a tier.
NAMING THEM
Clearly, matching what you sell. starter, business, professional.
Not package1, package2.
CHANGING A CLIENT'S PLAN
WHM > Modify an Account, and select the new package.
Takes effect immediately.
FEATURE LISTS
Control which cPanel features clients see. Useful for hiding things you do not want them using.
Be careful: hiding backups or SSL because you find them confusing costs you support requests when clients cannot do things themselves.
WHAT TO SET SENSIBLY
Mailbox quotas, so one mailbox cannot fill an account Realistic disk limits
