Make sure you know what they want from you. Not clear requirements could mean there are problems inside the company or they don't want to deal with you too much. In either case not clear requirements could be beneficial or very non-beneficial for them since if you aren't sure what you are building you might build anything that works from your point of view. Make sure you sort this out before you build it.
