wav3front What's worse is that these kind of packages (5, 10 or even "unlimited" websites) are very common, you can find those kinds of offers in known hosts.
Why should someone choose a company that offers 1 website for similar price?
Just set your packages to allow only one website with unlimited addon domains, and adjust CPU/RAM limits wisely. That’s basically how the big hosts do it (with Cloudlinux) , and it works much like cPanel’s model.
For backups, enable cPFence's WordPress per-install bi-weekly backups alongside the great daily Enhance backup, so if a client only wants one WP site restored separately, you’ve got it covered.
The only drawback is all domains under that package will share the same PHP version, but in 2025, that’s really not a big deal.
