BOOKKEEPING & TAX FOR GROWING ECOMMERCE BRANDS

Turn your messy business finances into clarity, confidence & growth.

Don’t let sh*t books hold you back. Get clear on your profitability, stay compliant, and scale your online store with proactive accounting built for ecommerce businesses.

Ecommerce accountants
  • Clear numbers
  • More time
  • Real profitability
  • No surprises

Most ecommerce brands struggle to make confident decisions because their financials are a mess.

  • You’re guessing at cashflow, not managing it: Without clean books and timely reporting, it’s hard to know what’s safe to spend or whether you’re actually making money.

 

  • You’re making decisions without real data: Hiring, inventory, and ad spend all feel risky when you’re relying on gut feel instead of accurate, ecommerce-specific numbers.

 

  • You’re stuck in the weeds, not scaling: Time spent chasing receipts, fixing errors, or waiting on your accountant means less time growing your brand or improving margins.

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.

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.

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.

Looking forward to what the future holds with support from Day One Advisory

Get clarity, control, and confidence in your ecommerce financials.

We get it, running an ecommerce business is complex, and your numbers often feel like the last thing you have time to sort out.

When your books are behind, your margins unclear, and your accountant slow to respond, every decision feels risky. You’re juggling inventory, ad spend, and customer service, but without clean financials, it’s hard to know what’s working or where the money’s going.

With fixed-fee support, ecommerce-first processes, and deep experience across strategy and accounting, we help you clean up your back office and make better decisions fast.
