PayPal is one of the most well known apps for sending money, paying online, and setting up merchant accounts.

Competition in the online payment space has made it so several viable alternatives to PayPal provide both merchants and personal users with more features. For merchants, alternatives to PayPal that support payment processing may work better depending on their focus, such as Amazon Payments.

In addition to this, PayPal as a service for sending money has compelling alternatives as well. Features such as support for cryptocurrency and no-fee money sending have infused some much needed competition. Because who likes spending money just to send money you already have to someone else, right?

With PayPal being available on both the web and as a dedicated app for smartphones, this availability is part and parcel with how it's become a ubiquitous service for Internet payments.
