I would like to hear from developers who have a good portfolio of completed and fully working ecommerce sites.<br/>I would like to use existing code you have developed rather than build an ecommerce site from scratch.<br/>Our aim is to build an automated ecommerce site that integrates with our suppliers and automatically produces a shipping list for us to send to a warehouse that will then ship products.&nbsp; The site has to be as automated as possible.<br/>The admin area will integrate with the warehouse and have a warehouse management screen.<br/>There will be a call centre application where orders can be checked or placed through manually.<br/>Payments will automatically go to suppliers after authorisation.&nbsp;<br/>All transactions are stored automatically or can be exported to a UK accounting system like Quickbooks or Sage.<br/>The site has to pass W3C validation and work in&nbsp;<br/>Firefox 3, 3.5<br/>Internet Explorer 6, 7 and 8<br/>Google Chrome<br/>Opera<br/>Safari<br/>The site must be easy to template using only external CSS and images.<br/>Ecommerce site will integrate will the stock systems of various suppliers.<br/>Platform can be PHP or .Net.&nbsp;<br/>Would also be interested in an e-marketing application that could be integrated into the admin area like mail chimp.
