What our clients are saying.

Before these guys, we were stuck with accountants who didn’t fully understand the complexities of our industry, gave incorrect advice, the processes were always harder then they needed to be and it always felt like we were treading water.

We’re now confident in our financial processes and have a clear picture of where we stand—something we never had before.

Day One Advisory is really good at what they do. With them on the team it is much easier to see the business’ financial health and have foresight. They set up our Xero account with the correct app stack and flows. They now do our books on a weekly basis, create budgets and set financial goals for the year. It’s like having a personal trainer for the financial health of your business. I highly recommend Day One Advisory to any body looking for great accountants especially in Ecommerce.

I’ve been with Day One Advisory since mid 2022. Matt has helped to educate me on Xero as well as the financial obligations of the e-commerce space. I’m quite happy with my experience so far and would definitely recommend him as an excellent accountant and financial advisor.
