I'm looking for a simple solution to accepting payments for services rendered. Specifically, I am acting as an auction deputy and I purchase items for people that can not otherwise buy them and then ship the items to them. As such, the pricing of the items is going to vary widely and is unique to each purchase. The best way I can see doing this at the moment is an invoicing system, in which I send the auction winner an e-mail invoice with a link to an individually customized foxycart checkout page.
Would Foxycart be able to handle something like this? The only alternative I've found so far is PayPal's basic e-mail invoicing system, but I hate that you can't customize their templates and that they make the non-paypal payment gateway so difficult to find.
