Outsourced finance for 7 and 8 figure ecommerce brands

Run your Shopify brand on numbers you can trust.

Know your real margin, trust your numbers and make big calls with confidence. We take the whole finance backend off your plate, so it stops being your second job.

On the call we review your profitability and unit economics, so you leave knowing exactly where your margins stand.

Know your real margin

Books you can trust

Hours back every week

No tax surprises

At 7 and 8 figures, unclear numbers get expensive.

  • You don’t know your real margin: Without clean books and timely reporting, it’s hard to tell which products, channels and campaigns are actually making money.
  • Big decisions rest on gut feel: Hiring, inventory and ad spend carry real money at this size, and they feel risky without accurate, current numbers behind them.
  • You’re still carrying the backend: Chasing invoices, fixing Xero and coordinating your bookkeeper, payroll and accountant is time you’re not spending on growth.

What changes when we take over.

  • You know your real profit and margin every month, not nine months after year end.
  • Your inventory and COGS are right, so your margins finally make sense.
  • You stop being the go-between for your bookkeeper, payroll and accountant.
  • Tax is planned before 30 June, so the bill is never a surprise.
  • Hiring, inventory and ad spend calls are made on facts, not gut feel.

What you get.

Not a list of services. A finance function that gives you answers.

Numbers you can trust

Books closed every month with inventory and COGS done properly. Open Xero and believe what you see.

No missed deadlines

Pay runs prepared, supplier bills coded, and BAS and tax returns lodged on time, without you keeping track.

Answers, not just reports

Monthly reporting that tells you what changed, why it matters and what to do next.

Your time back

The backend runs without you coordinating it. No chasing invoices or fixing Xero at night.

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!
Review from Google
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. 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

What it looks like in practice.

Three brands that came to us with numbers they couldn’t trust, and what changed.

$400k
of overstated sales corrected

Fixing years of incorrect accounting

The problem

An established ecommerce brand’s books couldn’t be relied on. Historical errors had overstated sales by about $400,000, with unreconciled payment gateways, incorrect clearing accounts and old balances nobody could explain.

What we did

  • Corrected historical sales and clearing accounts
  • Reconciled bank and payment gateway balances
  • Cleared old balance sheet balances and fixed the loan accounting
  • Set up a proper monthly close with supporting workpapers

Reconciled, supported numbers every month, and owners who finally trust their reports when making decisions.

1 view
consolidated every month

One clear view of a multi-entity group

The problem

A successful ecommerce group traded through several entities. Each Xero file showed its own piece, but the owners couldn’t see how the group was performing as a whole.

What we did

  • Monthly adjustments and reconciliations for every entity
  • Consolidation with checks that agree back to Xero
  • Month, year-to-date and historical monthly P&Ls
  • An ecommerce performance report and commentary alongside the accounts

One consistent consolidated view each month, so issues are spotted earlier and decisions are made on current numbers.

28,500
broken transactions cleared

Rebuilding a broken ecommerce setup

The problem

A previous integration had created around 28,500 unusable invoices and payments that couldn’t be recoded or voided, across two Xero files that still needed consolidated BAS reporting.

What we did

  • Cleared the broken transactions and rebuilt Shopify accounting on A2X
  • Cleaned up the chart of accounts and split D2C and wholesale revenue
  • Set up inventory, stock in transit and consolidation processes
  • Introduced monthly workpapers and management reporting

Fully up to date, with a setup that produces accurate, repeatable monthly reporting instead of recreating the same problems.

How we compare

When you work with us:

  • Specialist in ecommerce (Shopify & Xero)
  • Fixed fees, clear scope, no surprises
  • Automation and integrated workflows
  • Proactive and ecommerce-specific advice
  • Timely, accurate, and actionable

Traditional providers:

  • Limited ecommerce knowledge
  • Hourly billing, unpredictable costs
  • Manual processes, slower turnaround
  • Reactive, generic guidance
  • Basic compliance-focused reports
