About Simple Books Bookkeeping

Helping Australian tradies and small business owners stay compliant, calm and in control of their money since 2015.

Why Choose Simple Books

Why Work With Me

I’m William, a bookkeeper and licensed BAS agent who genuinely enjoys working with numbers – so you don’t have to. I studied accounting back home in New Zealand before moving to Australia, and I’ve spent more than 15 years helping business owners get their books under control, lodge BAS correctly, and finally understand what their numbers are telling them.

Tradie-friendly

I work closely with builders, plumbers, truck drivers, steel fixers and other trades, and I understand the long hours and tight deadlines that come with the job.

Relationship-driven

One of the first clients I ever took on – a builder who found me through a Gumtree ad – is still with me today, more than a decade later.

Calm & clear

I’m known for turning messy books into clean, easy-to-read reports and explaining everything in straightforward, everyday language – no confusing accounting jargon.
