Searching for a tool to use as a fake interface

Hi All,

I hope someone can help me with this issue.

We have to test a complete order cycle. But not all of the business partners do have test environments.

And in the order cycle there are a lot of interface moments to check. Sometimes based on SOAP or just a file (FTP, mail...).

So the tool we are looking for should provide us with a possibility to make a mockup interface and then sends back pre programmed responses. So someone is able to test a complete order from start to end, including feed back from all interfaces. 

Is Testcomplete the tool to use in this case?

TIA
