The ongoing support from BYO books has just been fantastic. Diane and her team is extremely responsive and reliably intuitive to my needs, demonstrating their commitment to great customer service and their superior knowledge base on bookkeeping issues and how to use Xero to full advantage.

I have no hesitation in recommending Diane and her team at BYO Books to any business needing a responsive and reliable bookkeeping service.

We were using a manual Excel system of record keeping prior to working with BYO Books. Diane made the transition to Xero as seamless as possible without too much stress or work from me.  We now use Receipt Bank and she manages everything remotely. Our records are always up to date and I can request any report I like and she usually sends it within a couple of hours. The service level is excellent and we are always compliant with all tax and employer  obligations. I only wish I had made the change to BYO Books years ago as I now have more time to run my business rather than being the bookkeeper for it.

After many years of unreliable reactive bookkeeping we were thrilled to find Diane McCaffrey and her team at BYO Bookkeeping Services. Diane assisted us in developing a systemised, time efficient and proactive bookkeeping system for our small business. I find Diane and her team to be highly professional and efficient and a true pleasure to work with. And she is a great bookkeeper: diligent and detail oriented, down to the last penny. Diane continues to be an integral part of our success and we truly value and are grateful for our association with her.
