No, I have asked for this before in the form of a Manual Order system based on the Admin side of the cart, but alas no mod yet available.
The X-Cart Devs will tell you to place the order on the shopping cart side, as if you were the customer. This works for one order, but I guess the X-Cart Devs dont rely on repeat custom
, as there is no way to place a second order with that customer manually if you did this again.
X-Cart badly needs a manual order system, as a lot of businesses run over counter, Mail Order as well as on the net.
We are looking into developing our own based on some oscommerce code we had in a previous site, will let ppl know if it works.
