Wordpress Plugin ezlunch.co.nz

Hi, I need your help regarding WordPress, Is there any plugin in the which is similar to ezlunch.co.nz.
for example when someone login into the account, it delivers the lunch to their classes. I want similar things which I can promote in the factories and offices for lunch where people order and pay, they have their own accounts where they can add says $50, which keeps decreasing when they order.
Is there any WordPress plugin which can solve these problems.
