What account software do you use?
Is quick books any good?

We made our own (called "MyInvoice")
www.domain-control.co.uk/Invoice

Probably allow people to login to a test account soon.

Yup, myBilling.info. Can't wait 'til it's released, one thing I'm worried about is pricing and will this be compatible with resellers? I mean does it require root access or anything? Maybe I should post this in the myBilling.info forum at hostingchat.net :wink:.

Well the best advantage would be if your host uses mybilling.info, then you'd be able to use the reseller functions of that.

But if you're just looking to manage clients and accounting (not credit cards, since that would require root access to be able to install whatever you need to install for that... well least cybercash does that I think.... hm.. need to check on that.) You could use paypal though, that'd work.

but you wouldn't be able to setup accounts automatically, that would require root access.
