” I attended MYOB Accounts Payables and Accounts Receivables course that is run at Parramatta college by Katia Chehade. Coming from an engineering background and having no knowledge of bookkeeping or accounting, I always dreaded learning anything remotely related to the subject but as a part of my work I always had to deal with finance users and had difficulty understanding AP/AR transactions. Katia’s teaching style is suitable for anyone no matter their background or their knowledge level. She took out all the complexity and made bookkeeping very easy to understand, she explained the concepts with real life examples. I highly recommend Katia for her extensive experience, strong knowledge and teaching skills, I also admire her for her calm demeanor and friendly nature.”

Learning the different accounting softwares with Katia was a pleasure. Katia’s training is very professional, organised and friendly at the same time. She is very knowledgeable in the subject matter she deals with and delivers her teaching skills with utmost passion and sincerity. I wish her all the best in her future endeavours. 

Hats off to your hardwork and dedication, Katia. Thank you  for imparting great knowledge to your students. We have definitely benefitted from it. Sometimes you have also been an inspiration to us. We share lovely memories.

Katia is a wonderful trainer and mentor. Her sessions are not only focused on the theoretical aspects of the subject but also its practical significance and applications. The amount of knowledge, experience and professional skill sets that she imparts are insightful and helpful. Her high quality training on MYOB platform for AR/AP and Payrolls has helped me develop the correct attitude and skill set that an accounting professional requires.

I highly recommend her workshops and training.

Katia is a great trainer. I have done MYOB And PAYROLL Courses from her. She has thorough knowledge of them and she taught not only the theory part of these topics, but also took efforts to give us complete practical knowledge too. 

She has a great knowledge of MYOB, PAYROLL and other Accounting platforms. I am blessed to be her student and looking forward to learn more from her.

Susanne Underwood

Katia is a efficient trainer. She not only focused on the theoretical aspects of the subject but also on practical importance and its uses. The way she explains even a student without basics can understand easily. Her quality training on MYOB platform for AR/AP and Payrolls has helped me develop the skills that an accounting professional requires. After completing her training I got a chance to work as a volunteer.

I highly recommend her workshops and training.
