Guys, I want my client to get an automated invoice as soon as he/she signups for my services. is it possible to get this feature? or is there any tool or software to do that?
P.S. it should be completely automated process
You simply need a billing system script, there's lots out there and lots of them tailored towards specific things. For example, for hosting you could use WHMCS, HostBill, Blesta or ClientExec, I'm sure there are also a few more.
