From Our Clients

Kristine Dawson Dawson Electric,
"John and his team have helped transform my business. They have given me direction and a deeper understanding of my business. I would highly recommend Keyline if you’re looking for a strategic accountant partner for your business.” 
Anil O'Jeswi Orange Maple Property Management, Greenslopes

“They have proactively provided us guidance on the Grants and support available, strategies, and planning for our business. They are always available for a discussion on the phone; we know that they always return your call the same day.”

“We have tried other accountants; most will do what is required when you ask or follow up. Keyline is the only company in our experience that will be chasing you to do what you have to do by when you have to do it. We are certain they are the best of the lot for small to medium size businesses.”

Madalina Eisenstat ME Migration,
Fortitude Valley

“They identify key strategies in streamlining financial management and minimising tax exposure. They are also very responsive to any queries with knowledgeable and useful guidance.”
