Hi, I’m Kiri Williamson, Director of K Books

For 20 years I worked in management roles in the food industry before needing a career change. I had a Bachelor of International Business and decided to complete a Masters of Professional Accounting.

After that I went into a business partnership at a local tax accountant where I discovered my love of Xero.

But something was missing…

I wanted to work with clients on a more personal level and assist them with day to day issues. Being a small business owner myself, and being great with implementing systems to suit a businesses budget, I realised running my own bookkeeping business would be the perfect fit.

Running K Books has allowed me to help business owners focus on what they are good at by taking over the mundane, and increasingly complex tasks of bookkeeping and HR.

I love my work! Outside of business hours I love camping or jet-skiing with my three kids, and a bit of downtime reading a good book (if I can find the time!).

Trust your business with a Professional BAS Agent!

As a registered professional BAS agent we follow a Code of Conduct so you always get the highest quality service. Using an unregistered bookkeeper can be expensive, emotionally draining, and ultimately a waste of time. Have confidence in K Books, your qualified and registered Bookkeeper and HR Intermediary.

Our clients love having a professional partnership with K Books, based on mutual trust and respect.

We started working with K Books to streamline our bookkeeping, and now they also assist with our HR needs. Working with K Books and HR Central, we developed new employee contracts and implemented HR policies and procedures to ensure compliance with Fair Work. We also implemented the HR Central platform, so our staff have access to all new policies as they are updated. K Books has also been instrumental in helping us implement policies and procedures within our business, including governance, HR and operational policies, to enable us apply for NDIS registration.

We have had a great working relationship with K Books for the last 3 years and liaise on at least a weekly basis. K Books helped us move to a better inventory system, has recently been assisting us with HR matters, and always let us know about any changes that may affect our business. They also have a great working relationship with our Accountant, which takes the stress off us each EOFY as they liaise on our behalf. K Books are always available to call and nothing is too much trouble. We enjoy their down to earth approach and ‘can do’ attitude.

K Books not only do bookkeeping, they introduced me to a reputable accountant and handled my transition to STP. I have no desire to keep abreast of ATO related compliance matters, and I know I can trust K Books to deal directly with the ATO on my behalf, leaving me free to run my core business. I would highly recommend K Books for any small business wanting to transition to more professional, modern and sophisticated operations. Thanks to K Books I no longer keep a shoe box of receipts!

Director of Hornibrook Consulting

K Books and I have worked together for 5 years now and there is no one I would trust more for help, advice and providing me with an understanding of what I need to do to keep trading. K Books has helped me transition into new accounting software programs and always goes above and beyond expectations - answering my calls when I don't understand certain paperwork or attending meetings with my accountant. Thank god I found K Books - I never hesitate to recommend your services.
