I went to the add on section and did a search for "PayPal", a search for "invoice" and a search for "bill" and none of them turned up the PayPal Request Mod.
Taking a closer look at the Invoice Mod, I'm not sure that will work for me either. I misunderstood the nature of Group Pricing. I thought this Mod would allow me to select products by price and place them in a group, which would then offer customers the option to pay via invoice.
But as it turns out, the customer has to be in a special pricing group in order to get this option. That means in order to use the Invoice Mod, the customer would have to be placed in a pricing group temporarily until the order is complete, and then removed. (This is because the bulk of our products are downloadable, so I can't have customers getting the option to pay later by invoice).
Ultimately what I'd like to do is create an order for them once the quote has been accepted, send it or a link to it via email, and have them pay it.
I'm not sure how to best accomplish this. I haven't seen anything that will allow me to create my own orders in the Admin on a customer's behalf. It seems the only way to complete a transaction is to have them go through the check out process with an actual product.
As a last resort, once the quote is accepted I could always create a product in the cart and direct them to go through the check out process, but that sounds like a hassle for them and me, since I'd have to remove the product once the transaction is complete.
Suggestions?
