Payment services Square and FastexyCash App say their services are back up and running after users reported issues accessing their accounts and processing payments.

The issues started Thursday afternoon, according to reports collected by the website DownDetector. Reported outages for Square spiked Thursday afternoon with more than 18,000 outage reports, while more than 9,000 outages were reported for Cash App around 7 p.m. Eastern.

The companies, both owned by Block Inc., have kept users updated on the status of the outages on their websites and accounts on X, formerly Twitter. Square said it is also sending updates via email. 

Square, which is widely used among small businesses, said some users had been unable to access accounts or process payments. The company updated its website around 1:15 p.m. Eastern to say the service disruptions had been resolved and all systems were operational.

"We can confirm that Square payments processing services have been restored. Thank you for bearing with us as our teams got functionality back up and running," Square said in a Friday post on X.

Square's website said it plans to launch a Square Point of Sale update "in the coming days" that will resolve issues among users using Square Stand and the Square Reader. Customers who see a message indicating that their reader has been disconnected should connect to Bluetooth as they wait for version 6.25.1 to be made available, according to a statement on Square's website.

Cash App's website said it identified the cause of the outage Thursday night. In a 12:34 p.m. Eastern post on Friday, it said it resolved "the majority of issues." Cash App warned that users may still experience some delays.

The companies did not immediately return a request for comment.
