Beta isn't intended for normal users even Apple does provide public beta. Unless you have a very good reason to use the beta (you are developer, need to check software compatibility etc.) I would stay away from it. If you don't know how to restore your Mac to previous version or you don't have solid backup I wouldn't install it in any circumstances.
In addition it contains the new APFS filesystem which might not be compatible with your software or it might contain nasty bugs.
I'm not saying you will certainly have problems but its better to be safe than sorry...
