I don't see a way to pay the invoice electronically. If there is not a way to pay electronically because the merchant did not enable that process, it would be nice to see a message explaining that 'electronic payment to this merchant is not enabled'.

Or is it my error? Am I making some mistake and therefore not able to make a payment electronically?

I do not trust putting my checking account number online. How do I still pay by check?
