Revolut announced a partnership today that is a direct result of new open banking standards. The U.K.-based challenger bank has integrated with QuickBooks to enable Revolut for Business customers to sync their transactions with the bookkeeping software.

In a blog post, Revolut said that this “demonstrates a huge step forward for U.K. businesses” and it’s the first time the company has collaborated with a third party provider to use the new Open Banking APIs.

“It was only natural that we would team up with QuickBooks for this project, not only is it the world’s largest cloud accounting provider, but we also share the same customer-driven values; to deliver a best in class service through innovation,” said Domenico De Fano, Product Owner at Revolut for Business. “We understand the importance of accurate, secure and fast information to our customers, that’s why we invested the time to get the best connections in place with QuickBooks.”

Merchants that connect their business accounts with Quickbooks will receive real-time updates on payments, expenses, and cash balances to help them manage payroll, invoices, and taxes.

Revolut debuted its digital banking technology at FinovateEurope 2015 in London where the company’s CEO and founder Nikolay Storonsky showed off the app’s money transfer capabilities that help users avoid banking fees without actually using a bank.

Earlier this month the company tapped investment bank JP Morgan to conduct a $500 million funding round and issue it a $1 billion convertible loan, which will turn into shares if Revolut receives a U.S. banking license. Last week, the company launched in Singapore and announced plans to make its products available in the U.S. in the next couple of months.

Digital challenger bank Revolut has chosen Singapore as its first entry into the Asian market. And now, after a successful beta period during which the company gained 30,000 new members and learned valuable lessons about the Singapore market and culture, Revolut is ready for business in Asia.

As of this week, Revolut Singapore customers will be able to instantly send and receive funds to and from fellow Revolut customers in Singapore, the U.K., Europe, and Australia for free. Revolut Singapore customers will also benefit from instant spending notifications, access to the real exchange rate in 150+ countries for fairer overseas spending, free international ATM withdrawals, and in-app currency exchange. PFM features like bill-splitting, round up payments, and budgeting and analytics will also be included.

“The journey to Singapore so far has been both exciting and challenging,” Revolut Head of Marketing and Communications Chad West wrote at the company blog. “For every new market into which we expand, there are different rules and regulations. The challenge for us is to build things that work as we, and our customers, want them to, while adhering to official guidelines. Not always easy, as you might imagine.”

The company’s expansion to Asia comes as Revolut fortifies its U.S. business via a partnership with Mastercard that will bring Revolut cards to the U.S. by year’s end. Other big deals for Revolut of late feature the company collaborating with Xero to enable real-time expense monitoring, teaming up with DriveWealth to offer commission-free trades to its cardholders, and working with financial API provider TrueLayer to support secure access of financial data via open banking.

This month Revolut announced that it had hired JP Morgan to manage its $500 million funding round, as well as issue the company a convertible loan for $1 billion. The company currently has more than $336 million in capital from investors including Index Ventures, Balderton Capital, DST Global, TriplePoint Capital, and Mastercard Start Path.

Founded in 2015 by Vlad Yatsenko (CTO) and Nikolay Storonsky (CEO), Revolut demonstrated its platform that same year at FinovateEurope. Since inception, the company has served more than eight million customers, and processed 350+ million transactions valued at more than $44 billion (€40 billion).

Challenger bank Revolut has hired investment bank JP Morgan to conduct its $500 million funding round and issue it a $1 billion convertible loan, which will turn into shares if Revolut receives a U.S. banking license, reports Ruby Hinchliffe of Fintech Futures, Finovate’s sister publication.

Sky News sources revealed that Revolut is trying to achieve a new valuation of between $5 billion and $10 billion from the capital-raising, which could make it the most valuable fintech in Europe if it hits $10 billion, ahead of Monzo, Transferwise, Klarna and N26.

Currently the most valuable fintech in Europe is Adyen, a Netherlands-based data analytics firm valued at $8.3 billion.

It is not clear yet which of Revolut’s existing partners will be participating in the round. The challenger’s most recent partnership with Visa will see it expand to 24 new countries, as well as hire 3,500 new staff.

Having accumulated almost eight million customers since it was founded five years ago, and now on track to have raised almost $2 billion in its lifetime if it secures the full $1.5 billion from investors, Revolut is fast-becoming the top U.K.-based challenger bank.

However such exponential growth, with the bank quadrupling its revenue in 2018 and saying it will triple it again this year, yields greater regulatory warnings.

The Bank of England’s Prudential Regulation Authority has targeted faster-growing companies in the U.K. like Revolut, requiring them to have more rigorous stress-testing and prove evidence of greater challenges by board members to business strategy.

Revolut is also undergoing a significant management restructure, following accusations of alleged links to the Kremlin.

Currently gearing up to announce its new chairman Martin Gilbert, vice chairman of Standard Life Aberdeen, the challenger has also lined up former boss at Goldman Sachs, Michael Sherwood, and has already hired a senior executive from Metro Bank.

Revolut debuted at FinovateEurope 2015 in London. The company’s CEO and founder Nikolay Storonsky showed off the app’s money transfer capabilities that help users avoid banking fees without actually using a bank. The company has made recent headlines in fintech news for its partnership with Bottomline and for its appointment of new CEOs in Lithuania and Ireland.
