Hostbill has some nice things.
I like the separation of client accounts between private individuals and companies. I also like that I can set custom fields to appear only for private individuals, other fields only for companies, and other fields only for companies in our country, and not for customers from abroad. This fine-tuning is quite lovely.
There are more fine-tuning settings that WHMCS doesn't have.
What I don't like is the design (UX/UI). To be fair, it's not just Hostbill, also WHMCS, Clientexec and Blesta are bad at this. I cannot believe that in 2025, with so many UI kits available for free, people who make these dashboards are incapable of building something nice-looking and usable. At least with WHMCS, you can get Lagom for the frontend, and the backend is decent. Hostbill has the worst backend, tiny font sizes, bad design choices, etc.
For many people, this seems insignificant, but we spend almost all day inside this dashboard, and if it's not a pleasant experience, it contributes to fatigue.
