More about Axure - the industry standard prototyping tool

If you want to test a website which has not yet been developed, then an Axure prototype will enable you to test your concept early. This has two advantages. Firstly, to test the proof of concept and that the system is worth investing in. Secondly, it allows you to test before a test system has been developed. This can save you time and money at a later date.

In case you're wondering, Axure is pronounced "Ack-Shore"!
