Our Clients say: 

Amanda Kennedy | Hammersmith Constructions | Brisbane | 
Congrats for your 20 year celebration last week.  That is a massive milestone to hit, well done to you and your team.
Thanks for all your assistance over the past six years.  You have been my Quickbooks/Reckon Guru from the early days of our business, providing guidance and support through the world of book keeping and accounting.  With your knowledge and understanding, I have gone from a complete novice to confidently and competently managing the bookkeeping of our construction company and I am most grateful for all you have done.  Knowing you are but a phone call or email away has taken all the stress and confusion out of it. So a big thanks from me and Brett.   

Small enough to care...experienced enough to understand

I was introduced to Karen from Cascade Consulting by another solicitor about 10 years ago. The other solicitor was full of praise for Karen and how she had helped him with his business. I was dissatisfied with my accountant at that time and had been looking for someone else to engage. 
I made an appointment and met Karen and was impressed with her knowledge and approach to business. I am the Principal of a small legal practice which employs three staff and I had specific concerns that as I was only small, would the larger firms be given preferential treatment. Karen assured me that I would be provided with the same high quality service and advice that all of her clients receive. 
I can say that in the time since Karen has become my accountant and became my contact for the legal software system I installed, there has never been a time when I have had to wait for Karen to get back to me. Karen has been fabulous in providing ongoing training and responses to my questions. 
The support system she has built is fantastic. I would whole heartedly recommend Karen in her role as legal software support management and accounting.
 I am available to talk with any perspective client about the services Karen provides.

​We have been working with Cascade Consulting Services Pty Ltd since 2006 when we purchased our first program for our trust account.  Cascade Consulting Services Pty Ltd was recommended to us by the former Auditor for the Queensland Law Society, Grenville Hughes.

Patricia P |Melbourne Victoria Australia |  

I can't begin to thank you for your assistance over the last few days. You helped us successfully meet the financial standard with XXXX.

Finally we can breathe a little more easily however we are still waiting on the delegate to actually sign off on the accreditation.   Your support not only with the XXXX but also over this last year has been amazing.  I don't consider you as our accountant but my true friend.

You are an amazingly kind and brilliant human being.  I am very privileged to be associated with you.

It is with pleasure that I provide this testimonial of Karen McDonald and Cascade Consulting Services.
Ms McDonald has been a consultant to our law firm for a period of approximately 12 years.  Firstly, as the technical support and manager of PC Law, secondly, as our accountant and thirdly as the proprietor of Wise Owl.  Ms McDonald has provided extraordinary technical and professional assistance over an extended period.
In particular, Wise Owl provides a cost effective and efficient software programme totally servicing the requirements of the QLD Law Society and the firm itself.   Ms McDonald’s level of expertise and support is cost effective, speedy and professional, the consequence of which lessens any negative impact upon the firm.   I have no hesitation in recommending Ms McDonald and Cascade Consulting Services.
