I own a small local web and graphic design business online. Recently ive been looking to get hold of a nice login system, that allows my clients to sign up, log orders, send private messages to one another, send invoices, possible payment system (maybe something simple that states which method they wish to pay .. like moneyorder, cheque, paypal etc) and a nice control panel for adminastrators or support. If anyone knows of any scripts that are similar or scripts you think are perfect for what I am looking for, please post them here, Id very much appreciate it, thanks
