The Real Cost of Manually Processing ATO Letters in an Accounting Practice
Download, read, file, redact, email: a worked example of what manual ATO correspondence handling costs a practice with 100+ clients, with assumptions you can change.
Ask a practice owner how long ATO correspondence takes and you'll usually hear "not that long". It's a few minutes here and there, so it never shows up as a line item. But those minutes repeat across every client, every notice and every week.
This post walks through a simple worked example. The numbers are illustrative assumptions, not benchmarks, so replace them with your own.
The steps in a manual workflow
For each piece of ATO correspondence, a typical manual process looks like this:
- Find and download the document from the portal or inbox
- Identify what it is and which client it belongs to
- Read it for amounts, due dates and anything that needs action
- Redact TFNs where your process requires it
- Rename and file it in the client record or practice management system
- Write the client email summarising what it means and what to do
- Log or track the due date so it isn't missed
Each step is small. Together they're the whole job.
A worked example
Assume a practice with 150 active clients and, for simplicity, an average of 2 pieces of correspondence per client per month. That's 300 documents a month. Many practices receive more around lodgment and activity statement periods and fewer at other times, so treat this as a rough average.
Now assume the steps above take about 12 minutes per document on average, including context switching:
- 300 documents x 12 minutes = 3,600 minutes
- That's 60 hours per month
If the work is done by someone whose time is worth $50 per hour to the practice (salary plus overheads), that's about $3,000 per month, or around $36,000 per year.
Change the inputs and the result moves quickly. At 8 minutes per document it's 40 hours a month. At 20 minutes it's 100 hours. The point isn't the exact figure. It's that the cost is real, recurring and mostly invisible.
The costs that aren't on the timesheet
Delay. A notice that waits two days in a queue before anyone opens it loses two days of its response window. For time-sensitive items, see how missed ATO correspondence can escalate into Director Penalty Notices.
Errors. Copying amounts and dates between a PDF and an email by hand invites mistakes. A wrong due date in a client email is hard to take back.
Privacy exposure. Every manual copy of a document is another place a TFN can sit in the clear. See TFN redaction for accounting practices.
Opportunity cost. The hours spent on correspondence are hours not spent on advisory work, which is typically better value for both the practice and the client.
Key-person risk. If one person knows how the process works, their leave becomes a business risk.
What automation changes, and what it doesn't
Automation tends to remove steps 1 to 5 and much of 6 and 7: documents arrive without a manual download, are classified, have key fields extracted, are redacted and filed, and a client email is drafted. What it shouldn't remove is human judgement. An agent should still review what is sent.
Be realistic about savings. Reviewing a drafted email and checking an extracted due date still takes time, so the right comparison is a short review per document, not zero minutes. Even so, if review takes 3 minutes instead of 12, the example above drops from 60 hours a month to 15.
Run your own numbers
You can do this in ten minutes:
- Count the ATO documents your practice handled last month
- Time five of them from arrival to client email
- Multiply, then add the delay and error costs you've actually experienced
Where ATOque fits
ATOque automates the fetch, classify, redact and draft steps for Australian practices, and leaves the review and send to your team. It is currently in waitlist stage. If you'd like to see how it would handle your volume, join the waitlist, or see how it works.
