Settling credits

[Andrew Greig]

Hi,

I have a customer who overpaid their account by $9.90, and at last I
have got back to them with a cash refund.  How do I process this
transaction so that their account will be shown as Nil.  I have tried
doing a negative "Payment of Account" with the funds coming from
Assets>Petty Cash.  But gc would not allow it.  If I come in through
Petty cash, how do I allocate the payment against their account?   Or
preferably - a better way.  

Thanks
