Prestashop Module Invoice

Now we need a module that allows the customer when the check out to the few select invoice. The invoice we write then out here in our management software so module should not have any features. Thus, the module will only do so the customer can select an invoice and then put in the bill in their package when we ship the goods! i think its take about 1 hours so make. You should be able ldda it into module on performance shop admin. PrestaShop™ 1.4.7.0
