Dropbox will use Adyen to provide international payments services.
The global payments technology company will provide payment options across 12 European countries, with plans to expand the service to Latin America and Asia later this year.
Customers in these markets will be able to purchase Dropbox through Direct Debit, and can expect new payment methods to be added later this month.
Software-as-a-service providers, including cloud services such as Dropbox, can expect to see revenues of $75 billion in 2015, according to research by Forrester.
Johann Butting, Head of Dropbox in Europe, Middle East and Africa said, "Dropbox has 120 million users in Europe and is growing faster here than in the U.S. As we grow it’s important we meet the needs of our customers, large and small, across different European countries.
"Adyen emerged as a great way to process multiple payment methods through a single platform, and will enable all our customers to pay with their preferred payment method."
Pieter van der Does, CEO of Adyen, said "The demand for cloud storage is exploding, and we are thrilled to help Dropbox build on its success by providing access to more than 250 payment methods globally, and ultimately improving the customer experience in new markets."
He continued: "Just as Dropbox makes it simple to save and share files everywhere without losing a file, Adyen is making it easier for Dropbox to process payments anywhere – without losing a customer."
