I have a similar setup using <a href="http://www.clientexec.com" rel="nofollow">Client Exec</a>. It is essentially a web app to bill for hosting but can also bill for one off work and other services. I can raise invoices with it and the clients can pay online with a variety of payment gateways ( I use Paypal). Clients can also submit support tickets, download files if needed and review invoice history. If you are really into hosting then it will plug into a few control panels e. gPleask and can automate the whole sign up process from your own site.
