OSC checkout - payment - customer invoice

Hi, I have two issues I need to solve, for a unmodified osc shop. The first actually is too small to justify an own project, but separate delivery is preferred. 1) Simple payment module needed! I need a payment module, that, when chosen, displays the payment information on the confirmation page. Preferably display it with a little text in a “payment information” box. A box similar like the one the credit card module uses would be nice. The module is not supposed to connect or do anything. I only need it to DISPLAY the information. This should be a very quick and easy thing to do. 2) Looking for an option to allow the customer to modify his invoice I need the offer my customers the option to modify their invoice/packing list. I want to be able to print this modified invoice, but don’t want it to affect any reports. If there would be a button “amended invoice” besides the “invoice”, “packing slip”, “back” button that would only show when there is an amended invoice, I would consider the problem solved. Kind regards,
