We need a Prestashop Module that will make a Pay Bill Now option on the invoice. We currently have the OleDiffPay module for deferred accounts and that adds up the customers bill, all we want is a button on that module that when they click Pay Bill Now it will take the total amount owed from that module and add it to the shopping cart so they can pay that. Similar to the Request A Quote module. So basically its a mix of the Request A Quote module & the OleDiffPay module. Please give me a quote for this. This is job is way past due and needs to be done ASAP!
