What we do.
We offer more than just number-crunching.
We provide the financial systems, insights, and proactive support needed by $500k – $20m ecommerce businesses to grow.
Bookkeeping
Accurate, up-to-date bookkeeping built for ecommerce brands using platforms like Shopify and Xero.
We take bookkeeping off your plate, saving you time, reducing errors, and giving you back the headspace to focus on sales and growth — not spreadsheets and reconciliations.
Tax
Stay compliant without the stress. We proactively manage your GST, BAS, and income tax obligations, so you always know exactly where you stand.
No last-minute panics, no nasty surprises — just clear, timely lodgments that protect your business, keep you compliant, and give you peace of mind.
Advisory
Make better business decisions with real financial insights. We help you understand your true profitability, track the metrics that matter, and plan for smarter, sustainable growth.
Whether you’re scaling up or refining operations, our advice keeps you moving forward with clarity and confidence.
Take control of your ecommerce business.
Growing an online business is tough enough without second-guessing your numbers, falling behind on bookkeeping, or stressing about tax obligations.
At Day One Advisory, we help Australian ecommerce brands stay financially healthy, profitable, and fully compliant — with proactive bookkeeping, tax, and advisory services built for the way you do business.
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.
