The peer-to-peer concept is coming to virtually every corner of human existence. That includes the hospitality industry. Through AirBnB you can actually rent out your house for various lengths of time for a predetermined fee. That gives you an extra income on your house and gives the visitor the benefit of having an entire house, rather than being crammed into a single hotel room.
A thing that needs to be ironed out for your online business is your billing service. While there are businesses that may bill their clients directly after a contract has been agreed upon and signed and these bills are paid for through checks that are deposited into the service provider's bank account, there are some clients who require a certain online billing system for them to pay for the services they have contracted. You may need to register with a billing system like PayPal for your online business to make billing and payment easier and less of a hassle to you and your clients.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
