What They Say About Us

“As the manager of a new startup company with minimal understanding of book-keeping / accounting, I was a bit nervous at the beginning, especially when Xero was a new system to me. Cornerstone made it super easy for me to get started. Being a small business operator it is very critical to have prompt accounting / book keeping assistance. I must say that the Cornerstone team is very helpful and amazingly efficient”

Elaine Tsung (CEO), Garage Society GarageSocietylogo

“Cornerstone is the next-generation accounting and book keeping company we have been looking for. Cornerstone has the know-how and capability of using Xero to make accounting actually useful to conducting a business and not just satisfy statutory requirements. Cornerstone not only helped us get our books in order but their process provided us with much more insights into our financials. I would recommend them to business owners looking for a modern approach to accounting and bookkeeping.”

Gene Soo (Co-Founder), StartupsHK


“Our ice cream shop opened in October 2015.  Adrian and Angie were instrumental in setting up and integrating our POS, inventory management system and Xero.  They are real experts who know the issues and limitations with each platform, and were able to advise us on the best solution to keep track of of our sales, stock and accounts without incurring the high costs of a bespoke system.

We cannot speak highly enough of Cornerstone, and would thoroughly recommend them as long term accountants and advisors.”

James Gibson (Director), Emack & Bolios


“Watermark is grateful for Cornerstone’s partnership of technical and financial expertise. Gone are the days of time and effort-wasting technical issues our old accounts software, as well as confusion over what our numbers mean. Cornerstone’s reliable bookkeeping in Xero, customized problem solving, flexibility and efficiency has kept our day to day financial operations streamlined, and provided leadership with timely, relevant and readable information in their hands with which to make important budgeting and spending decisions. It has been a real pleasure to work with the friendly staff at Cornerstone.”
