Your four admin staff cost far more than the $360k on the payroll. Count the friction they pass to every other role and the real bill is closer to $900k a year. Fix it and the same team carries twice the clients.
Pull up the payroll register at a 25-person Australian accounting firm. Four admin staff. Call them Sarah, Priya, Tom and Linh. $75,000 each.
That's $300,000 a year, plus super, plus the desks, plus the software seats. Call it $360k all in.
That number is the cheapest part of the answer.
The real cost of your admin team is not what you pay them. It's what their workflow drags out of every other role in the firm.
And most of all, what it drags out of you, the principal, on a Sunday night in early September, at the kitchen table reformatting a tax binder because Priya is off sick and the lodgement is due Tuesday.
That cost line never makes it into a board pack. It deserves to, because the firm that gets it right carries twice the clients on the same team.
Your admin team burns 160 hours a week on work nobody bills
Sit with Sarah for a Tuesday in late August and time-stamp her day. The hours don't go where you think.
She arrives at 8:15. Until 9:30, she is chasing signatures. Twenty-three engagement letters sitting unsigned in DocuSign because clients said they'd do it after dinner and didn't. She drafts a polite chase, sends it, then a follow-up text for the seven that have been sitting more than five days.
From 9:30 to 11:00, she's collecting KYC for a new family group: ID for four individuals, beneficial ownership for the trust, ASIC extracts for the company. Nothing is in one place. Everything arrives in the wrong format. She converts, renames, files.
After lunch, she's drafting cover letters for the four returns that came back from review yesterday. Each one is bespoke in tone but ninety per cent identical in content: here's your return, here's what you owe, here's the lodgement timeline, please sign by this date.
From 2:30 to 4:00, she's assembling binders for tomorrow's meetings: cover letter, return, supporting schedules, prior-year comparison, fee invoice, payment instructions. Print, collate, label, courier.
The last hour is reminder emails. The clients who haven't paid last month's fee. The clients whose KYC is about to expire. The clients who promised their crypto records in March and haven't.
Now multiply Sarah by four. That's your admin team in tax season. Roughly 160 hours a week of human attention going into chasing, assembling, formatting, reminding and filing.
None of it is billable. All of it is necessary.
The real cost isn't their salaries. It's the friction tax on everyone else.
Here is the part most firms miss. The cost of the admin layer is not the admin layer. It's the friction it lets through to everyone else.
When KYC isn't done by Tuesday, the engagement manager spends Wednesday morning chasing it instead of reviewing returns.
When the binder isn't ready by 4pm, the partner takes it home and fixes the formatting at 11pm.
When the e-sign chase didn't happen on Friday, Monday's lodgement queue is short and the firm misses targets.
Put a dollar figure on it. A mid-tier firm charges a partner out at $550 to $700 an hour.
Say six partners each lose three hours a week to work a $40-an-hour admin process should have handled. That's eighteen partner-hours a week, fifty-two weeks a year, at $600 an hour.
Just under $560,000 in opportunity cost. Every year. In a single 25-person firm.
And that figure is conservative. It ignores accountant time, junior time, client churn from late lodgements, and the morale tax on senior staff who are sick of doing junior work.
So the real cost of your admin layer isn't the $360k you see. It's that $360k plus a half-million-dollar friction tax on the rest of the practice.
Closer to $900k a year, in a firm doing $5 to $7m in revenue.
Most principals look at the admin line in the P&L and ask whether they can run it with three people instead of four. That is the wrong question by an order of magnitude.
Admin is not a cost centre. It's an automation surface.
Every cost centre in a firm has a different relationship to technology.
Tax preparation has been chewed at for twenty years by Xero, MYOB, CCH, FYI, APS and BGL. Each generation of software has shaved a little off the time per return. The gains are real but incremental, because the work is intellectually messy and the tooling is mature.
Advisory and partner work resists automation at a deeper level. Judgement, relationships, accountability under the TPB code: this is the part of the firm that gets more valuable as the rest gets cheaper.
Admin is the opposite end of the spectrum. The work is high-volume, rule-following, document-shaped, and largely identical across firms.
KYC is KYC. A cover letter is a cover letter. An e-sign chase is a cron job with manners.
The reason admin hasn't been automated isn't that it can't be. It's that the tooling assumed admin should be made faster, when the right move was to take it out of human hands on the routine path.
In 2026, that has changed. Document understanding is good enough.
Workflow agents can chase, draft, file, reconcile and escalate on the routine path, and route the exceptions to a human only when something needs judgement.
The economics shifted under the floor while the admin team kept showing up and the lights stayed on.
I'll be upfront. This is the problem my company, Admiin, was built to solve: the workflow layer that runs the routine path automatically, with an AUSTRAC-aligned audit trail underneath. I'll leave the pitch there. The structural argument holds regardless of vendor.
Fix it and the same team carries double the client book
The firms that work this out in the next twelve to eighteen months are not going to lay off their admin team. That's the lazy version of the story, and it's wrong on its face.
What they'll do is double the client book the same team can carry, without breaking the partner.
A 25-person firm with four admin staff has a natural ceiling on how many SME and high-net-worth clients it can service well.
That ceiling isn't set by partner capacity or accountant capacity. It's set by admin throughput.
When KYC takes a week, when binders are built by hand, when the e-sign chase is a person remembering to follow up, you can grow the partner bench all you like. The firm cannot absorb more clients without the admin layer breaking.
Lift that throughput three or four times and the entire firm rebases.
The partners get their evenings back. The senior accountants stop doing junior work. The juniors stop doing admin.
The admin team itself moves up the value chain, into exception handling, client relationships and compliance ownership, rather than document shuffling.
The uncomfortable observation, if you're a principal reading this, is that you've probably managed admin as a cost line for fifteen years. That habit is now expensive.
The problem was never Sarah, Priya, Tom and Linh. It's the four hundred unsigned engagement letters in their inbox.
Fix that, and the firm you run in 2028 is barely the same business.
