there, i'm using a standard paypal with the pro-sites

hi there,
i'm using a standard paypal with the pro-sites plugin and i believe clients are getting confirmation emails every time the payment went through.
i can see on paypal site that it's possible to create some invoice templates but i'm not sure whether that'd would work automatically with the pro-sites plugin. any ideas?
some of my clients pay monthly, some quarterly and some yearly so that'd have to be 3 different invoicing templates, but i'm not sure whether it'd work with the pro-sites plugin.

thanks,
Adam
