Step-by-step explanation:
In your case the first step would be the need to acquire more information so that you may know what the job entails and if it is something you are able to do.
To do so you should request for information from the relevant people who in this case would be the VP of procurement. Ask the VP what the company would like in a vendor as well as why the Vendor is looking for a new provider so that you may know of any issues between the Vendor and their current providers. This would also contribute to you knowing what is expected of a vendor.
