@smashingred, enlightening as always.
I like the simplicity of TreasureChest but I need more UK payment gateways so for me FoxyCart is the only glove at the moment. Haven’t looked fully into how to integrate Royal Mails API but there are plenty of postcode suppliers dealing with SOAP and XML so something will work.
At the moment I’m in the situation of wanting to use FoxyCart but a bit stuck -
http://forum.foxycart.com/comments.php?DiscussionID=271&page=1#Item_0, but also just how much of the backend does your typical client need (loosely based term)!?!
I’m going out on a limb here as I’ve not yet had any client experience with cart request, but in my own research of finding a cart to use and looking at likes of ViArt Store the amount of features is enough, well its starting to put me off. Same with Volusion, not sure about CubeCart or Magento as haven’t looked at them yet.
One thing I’m not sure about is how FoxyCart deals with things like being able to order track, sales based usage and so on and then how much customizing is needed. I suppose there always more then one answer but there must be typical request. But I’m guessing FoxyCart does the shop bit, you then take the XML datafeed and put it into your CRM or accounting solution. Which I suppose gets away from the dread all-in-1 answer.
Now I’m rambling..
