A package is a template of limits. Create it once, then every account you sell on that plan gets identical settings without you deciding anything twice.
In WHM go to Packages, then Add a Package. The fields that matter:
- Disk quota and monthly bandwidth - in MB, so 10 GB is 10240.
- Max addon domains, subdomains and parked domains - the main lever between a basic plan and a bigger one.
- Max email accounts, databases and FTP accounts - unlimited is fine for higher tiers, but a low cap on your cheapest plan is a reasonable way to keep it honest.
- cPanel theme - jupiter unless you have a reason.
- Feature list - which cPanel icons this tier can see. Useful for keeping the cheapest plan simple.
Practical advice: build three tiers rather than seven. Customers choose faster from three, and every extra tier is another thing you maintain and explain forever. Name them after what they are for - Starter, Business, Pro - rather than after their disk size, so you can change the numbers later without renaming anything.
Changing a package does not retroactively change accounts already created on it. To apply new limits, use Upgrade/Downgrade an Account on each one, or select the package again to re-apply.
