It's really helpful to us that you have setup to accept online credit card payments but it seems to only be for one invoice. We need this function to accept payment of multiple invoices.
For customers that have 6 or 7 invoices per month it's easier for them to continue paying once by direct deposit, rather than having to pay each invoice seperately by credit card. Will you be setting up the online payment system so people can perhaps click the link and pay off their monthly statements so customers can pay their whole account instead of just one invoice ??
