[plugin: web invoice plugin] shorter user profile?

Hi there,

I have just installed the web invoice plugin which is great

http://wordpress.org/extend/plugins/web-invoice/

However in order for me to send a customer the invoice they first have to register as a user on my site …. the only problem is the normal user profile page which they fill out is really long and has fields like “boigraphical info” which they really dont need to fill out and it generally looks too long so they may just give up

Is there anyway of just making it so when they log in and set up their user account profile…all they have to enter is name, email and address ?

Or is there another way I should do it?

Any help would be much appreciated 🙂

wasnt to sure so I thought this would be the correct place to post this
