Unlike most other alternatives I've tried, Blesta team does seem to care about the users and fix any noted bugs.

It's not perfect, UI/UX and tutorials/docummentation could use some improvement, but it works, has modules to cover practically any use-case, great community support, and the further development seems to be moving in the right direction.

Great technical support too. I've never received an "all-works-on-our-end-bug-off" answer.

The bottom line is: I haven't regretted choosing this software for my business. It does the job, and it's good.
