Users in the US are now able to buy food and cinema tickets on the site - leading shares in rival apps to fall.
People who use Facebook in the US will now be able to order food from restaurants directly from their pages.
The social network has been adding new features over the last few months to allow users to shop without having to log in somewhere else.
The latest in the company's mobile app will allow people to buy food, purchase movie tickets and book appointments at spas and salons.
In a blog post, Facebook said: "We're introducing some new ways for people to take action faster once they've found something they want to do or a place they want to go.
"We're starting to roll out these initial experiences in the US today.
"This is the first step, and over the coming months we'll be launching even more new features that will make it easier to get things done, make confident decisions and communicate directly with businesses on your time and terms."
Facebook also said a new "recommendations" feature in the app aims to make it eaiser to get advice from friends and family on places to see and things to do.
Earlier this month, it launched "Marketplace", a platform that allows people to buy and sell items locally.
