Notifying investors and consumers that it has closed a recent $200 million Series D financing round from investors including Citi Ventures, Rizvi Traverse Management and Starbucks, mobile payment processing company Square announced today it is now processing more than $8 billion in payments on an annual basis.

News of Square’s recent round emerged when the company recently accepted a $25 million investment from Starbucks, with Square moving to handle the credit and debit card payment processing for the coffee chain’s US locations. Customers will also be able to use the Pay with Square application at Starbucks.

As part of the deal, Starbucks CEO Howard Schultz also joined Square’s Board of Directors, valuing the company at more than $3.25 billion.

However, Citi Ventures and Rizvi Traverse Management also joined the round, which is reported to be around $200 million mark, according to AllThingsD.

With additional funding, Twitter co-founder Jack Dorsey hopes his other growing company can push forward with its plans to roll out internationally. The company has grown from 150 employees and processing over $1 billion in payments annually in the last year to 400 employees and $8 billion in payments currently.
