Whilst most larger clients already have a Travel and Expense policy, the document by Concur is a good guideline for those that are looking to move towards a global policy or looking to simplify it for employees. Needless to say that it is an excellent starting point for small companies who are yet to have a formal policy.
Agreed, Amber . . . typically companies do not want to share their policy, since it can be one of the things that keeps them competitive in the search for talent. And, yes, Rohan, most companies already have an established policy, however, none of them are perfect. It's always good to benchmark your policy against what other companies are doing. All that said, I'm happy to share our company policy with anyone who will share theirs with me. I've made that offer in the past, and had a couple of people take me up on it. I shared and they didn't reciprocate. Put a bad taste in my mouth, but hope springs eternal. I'm still willing to share.
