“Derek and the team at Prime Accounting have been a fantastic addition to Silicon Beach Computers over the years. I remember we were two days from BAS due date in 2009 and desperately required a book keeper to reconcile our accounts. Derek came in fixed all the accounts and ensured it was submitted smoothly. Over our last 5 years, Derek has taught us so much that now we are able to reconcile ourselves and he simply reviews it and submits. So easy and effortless. Silicon Beach highly recommends Derek and his great work to other firms, his knowledge and skill is sound and best thing is he always try to help. Thanks Derek.”
