Irish-founded payments platform Stripe processed more than $18.6 billion in payment transactions between Black Friday and Cyber Monday.
This is the first time the financial infrastructure platform for businesses has shared real-time information on payments.
Stripe processed more than 300 million transactions, making it the largest ever four-day period on the platform.
At peak volume, the company said it was processing 93,304 transactions per minute.
"Black Friday can be a really stressful, high-pressure period for us," said Edward Whatmore, chief digital officer at Mountain Warehouse, a UK-based company and one of the world's largest sellers of outdoors equipment.
"To have a stable platform with a high rate of uptime is key, so fortunately we were able to switch to Stripe and push all of our traffic through the platform," he added.
David Singleton, chief technology officer at Stripe said they are focused on continuously improving reliability, as their customers respond to the surge in consumer demand.
"Peak days like Black Friday give us a glimpse into what an average day on Stripe will look like soon," he said.
"Stripe is already prepared to handle the much larger volumes our customers will need from us as their businesses grow," he added.
