Katia Chehade

Owner, Sudoku Bookkeeping

Katia has been our book keeper since 2009 and hasn’t skipped a beat. She works well with our accountant and ensures that we can focus on more important things, like running the business. Everything is explained to us thoroughly when required, and Katia keeps us up to date with any changes to ATO rules and regulations.

I can’t recommend a more honest and competent person.

Elia El Turk

Managing Consultant, Requal Management Solutions

We hired Katia as our Bookkeeper almost two years ago and we are very happy with her work. She performs her duties with a high level of competency, and through her many years of experience in the not-for-profit sector, she adds value to our organisation in many ways that are not written into her job description.

She keeps up to date with industry awards and ATO and other charity reporting requirements and has access to a wide network of online relevant forums and is always looking to upgrade her knowledge.  She is easy to get along with, approachable, flexible and available for any urgent off-site jobs.
