Project management and time tracking application

Hello folks!
First of all, all the best in the new year!

I am here because i need a avice or suggestion.I am a webdev freelancer who works for multiple clients (each of them owns several websites), and since i want to organize the way i work, i am after a project management application that could help me.
Basically, i need an application that could let me create document/project for each client, their websites informations (login credentials, site informations), keep track of things that i need to do on each site and a to have some kind of built in timetracker.Also, invoice creation and sending wouldnt be bad feature to have lol

I was wondering does anybody of you know any application (desktop app preferably) that could offer me these things

Thank you for your time and sorry if there are mistakes in post (not native english speaker).

Take care!

 

Are you using windows 8? There are many task apps for free.

gTask HD (syncs with google docs etc)
Task manager free
etc there's more, but many of them are good help.

Now if you know how make a website design for that, use project fork with Joomla.
Dotproject
PHProjekt

For desktop

Wunderlist
Google Task

Hope these help. Thanks

 

Have you tried working with jira. They have plenty of addons I believe there should be something that will work perfectly for you.

Thanks,
