About Day One Advisory
The finance team behind established businesses.
We run the finance backend for 7 and 8 figure ecommerce brands, so founders know their real numbers, stop carrying the admin and get back to growing the business.
7 and 8 figure brands
Ecommerce specialists
Principal-led
Fixed monthly fee
Growth changes what you need from your numbers.
Somewhere in the 7 figures, a bookkeeper and an annual accountant stop being enough. There is inventory to account for, a team to pay, suppliers to manage and decisions that carry real money. The numbers need to be right every month, not reconstructed at year end.
Most founders at this stage face a choice: hire a finance team, or keep carrying the backend themselves. We are the third option. You get the clarity and control of a good in-house finance team, without the hiring, the salaries or the management.
We specialise in ecommerce brands running on Shopify and Xero, and bring the same rigour to established private businesses in professional services, construction and healthcare.
Led by an accountant who reads the books.
Matt Byrne founded Day One Advisory in 2021. Before that, he spent his career advising large private groups and small cap listed companies on complex tax, CGT, international tax and trust structures.
He built the firm to bring that level of thinking to founder-led businesses. Every piece of advice and every tax return is reviewed by him before it goes out.
Originally from Busselton in WA, Matt now lives in Melbourne with his young family.
How we work.
Six things every client can count on, whatever the size of the business.
01
One team owns it
Bookkeeping, payroll, payables, reporting and tax sit with one team. Nothing falls between providers.
02
Monthly, not yearly
Your books are reconciled and closed every month, so you are never waiting until year end to see where you stand.
03
Reporting with a point of view
Monthly reports with commentary on what changed, why it matters and where to focus next.
04
Principal-led advice
Strategy and tax advice comes straight from the founder, someone who knows your business and your numbers.
05
One fixed monthly fee
Scoped to your business and agreed upfront. No timesheets and no bill shock.
06
The right systems
Xero, A2X and a tight app stack, set up properly so your data flows without you.
