What our clients are saying.

Just started working with Matt and the team and they have been great to work with... Very proactive and helpful sorting out our business and personal taxes and future planning!

We have been with Day One Advisory for 1 and a half years and Matt and his team have been nothing short of fantastic. They supported our business as a brand new startup and they still help us navigate through all the accounting challenges we have today. We look forward to using Day One for many years to come, I recommend Matt & the team to any business!

We have been with Day One Advisory for around 2 years or so now. Working with Matt and his team has been one of the best decisions we’ve ever made for our ecom business. 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.

From day one, Matt has been an absolute legend. These guys go above and beyond, always making sure every detail is accounted for and that we’re maximizing every opportunity. Their knowledge, dedication, and proactive approach have made an immeasurable difference to our business.

Thanks to Matt, we’re now confident in our financial processes and have a clear picture of where we stand—something we never had before. They’ve been instrumental in helping us grow, and we can’t imagine working with anyone else. Hands down, one of the best and most impactful decisions we’ve ever made!

Matt at Day One Advisory is fantastic. He's knowledgeable, patient and caring. He has also gone well above and beyond for us numerous times, and I could not thank him enough for doing so.

We're still new to e-commerce and we're still wrapping our heads around it all, but Matt has:
- thoroughly answered all of our questions,
- set up Shopify, A2X and Xero for us, and
- helped us get our bookkeeping and taxes in order.

We hope to work more closely with Matt and Day One Advisory in the future!

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.
google
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.
google
Working with Matt at Day One Advisory has been a positive change to my business. I highly recommend this firm if you want accountants who care.
google
Thanks to Matt and the team at Day One Advisory for a smooth transition from Quickbooks to Xero and for simplifying the accounting processes for my complex online business. Matt took care of the basics so I could get a more strategic view of my business and I am so impressed by the proactive support and advice given. Looking forward to what the future holds with support from Day One Advisory

Frequently asked questions.

How much does it cost?+

We work on fixed monthly fees so you always know what you're paying. No hourly billing, no surprise invoices. The exact fee depends on your transaction volume and what you need handled. We'll talk through it on the call and give you a clear number before you commit to anything.

What if my books are a mess right now?+

That's completely normal and exactly where most of our clients start. We'll do a full review of your Xero file, clean everything up, and get your books to a point where they're accurate and current. From there, we keep them that way on an ongoing basis.

I already have a bookkeeper. Why would I switch?+

Most bookkeepers aren't ecommerce specialists. If your Shopify-to-Xero integration isn't set up properly, your COGS is off, or your clearing accounts are a mess, you're not getting the full picture. We build everything around the way ecommerce businesses actually work - Shopify, A2X, Xero - so your numbers are accurate and meaningful, not just reconciled.

Do you handle BAS and tax as well?+

Yes. BAS preparation and lodgement, PAYG, STP, and annual tax returns are all part of what we do. Everything is handled in-house so there's no back and forth between separate providers.

How does the onboarding process work?+

We start with a free call to review your current setup. If we're a good fit, we'll send you a clear proposal with scope and pricing. Once you're on board, we get access to your Xero and Shopify, do a full review, clean up any issues, and set up the integrations properly. Most clients are fully onboarded within two to three weeks.

What if I'm not on Xero yet?+

We can help you migrate. Whether you're coming from QuickBooks, MYOB, or spreadsheets, we'll move everything across to Xero and set it up properly for ecommerce from the start.

Do I need to be based in Victoria?+

No. We're based in Melbourne but work with ecommerce brands right across Australia. Everything is done remotely - Xero, Shopify, email, and video calls. Your location doesn't matter.

What's the commitment? Can I leave if it's not working?+

There are no lock-in contracts. We work on a month-to-month basis because we'd rather keep you through results than fine print. If it's not working, you can walk away.

Do you work with Amazon, eBay, or other marketplace sellers?+

Yes. A2X supports Shopify, Amazon, eBay, Etsy, and Walmart, so if you're selling across multiple channels we can manage the integrations and reconciliation for all of them through Xero.

What does the free call actually involve?+

It's a 15-minute conversation where we look at your current setup, understand where things stand, and give you an honest assessment. No sales pitch, no pressure. If we can help, we'll explain how. If we can't, we'll tell you that too.

How do you communicate with clients?+

Primarily email and video calls. We're responsive and proactive - you won't be chasing us for updates. Most client queries are answered within a few hours on business days, and we'll reach out to you when something needs attention rather than waiting for you to ask.

Can you help with inventory management tools like Cin7 or Dear?+

Yes. We work with clients using Cin7, Dear (now DEAR by Cin7), and Unleashed. We make sure your inventory system talks to Xero properly so your stock values, COGS, and margins are always accurate.

What happens at tax time?+

Because your books are kept up to date throughout the year, tax time is straightforward. We prepare and lodge your business tax return and handle personal returns for business owners too. We also run an annual ecommerce tax planning session to make sure you're structured properly and not paying more than you need to. It's all included - no separate EOFY invoice.
