If a company doesn’t use a travel management company or have a proper system in place, managing travel spending become a challenge—especially when employees are booking their own travel.

You've carefully shaped your organization's travel policies to create effective habits that fit the specific needs of your organization. Some employers allow employees to take extra days at their destination if they want to use vacation time. Others have set limits on what employees can spend while they're traveling or how they're allowed to access the funds they use when traveling.

As a business travel manager, you have two key goals. First and foremost, you want to keep your bottom line under control; but you also want to be sure that your travelers are as happy as possible when they have to be out on the road. Travel is inevitable for many businesses, but not every employee enjoys travel—and many of them quickly become frustrated with the process.

With global business travel spending expected to reach $1.7 trillion by 2021, you need to be prepared to improve your company's approach to domestic and international travel.
