It all depends on your company's procedures. But what I would do is go to the travel tab and get started there. Be sure your profile is filled out and follow the prompts. Here is from a concur guide. So go to the trip search then do the following:
Reserve a Hotel Room Using the Hotel Search Tab
If you require a hotel but not airfare, use the Hotel Search tab. To do so:
Enter the check-in and check-out dates (or click each field and use the calendar).
Enter the search radius and choose either miles or kilometers. Concur will always show company preferred hotels within a larger radius, usually 30 miles or kilometers.
Choose to search near an airport, near an address, near a company location, or near a reference point / zip code (a city or neighborhood).
Click Search. The hotel search results appear.
