You did the year-end. You lodged the BAS on time, every quarter. You chased them for receipts, sorted out their mess, and got them a refund they didn’t expect. Then they moved to a cheaper accountant, or just stopped replying, and left your last three invoices sitting unpaid.

Accountants and bookkeepers are among the most under-paid professionals in Australia when it comes to unpaid fees, partly because you’re too polite to chase. It’s time to stop being polite.

You have two ways to deal with this:One of them is done for you.

Your engagement letter is a contract

If you issued an engagement letter (as your professional body requires), you have a written contract setting out the scope and fees. Even without one, a client who instructed you to do the work and accepted the outputs owes you the fee. Their tax return was lodged. Their BAS was accepted by the ATO. The work is done and provably so.

Liens on client documents

Accountants have a common law lien over client documents they’ve worked on until fees are paid. That means you’re generally entitled to hold their working papers and files. There are limits (you can’t hold documents that belong to the client and pre-date your engagement, and professional rules apply), but a polite mention of your lien in the letter is often enough to prompt payment.

The Letter of Demand

A Letter of Demand is the last step before formal action, and for accounting fees it’s remarkably effective. It should:

  • Reference the engagement letter and the services performed, with lodgement dates
  • List each unpaid invoice with amounts and due dates
  • Note any interest or recovery costs under your terms
  • Set a 14-day deadline
  • State that a small claims application will follow, with interest and costs, and that any judgment will affect their credit file

Small business clients especially do not want a default judgment on the record. It affects their ability to get finance.

Where they’ve gone quiet

Send the letter by email and by post to their registered address (check ASIC or the ABR if they’re a company). If they’ve moved, a bit of searching usually finds them: they’ve registered a new business, updated LinkedIn, or their new accountant has lodged something. Serve on the entity you engaged with: if it’s a Pty Ltd, the company; if it’s a sole trader, the individual.

The cost of not chasing

For a small practice, $5,000 in unpaid fees might be a month of profit. Every month you wait, the client is less likely to pay and more likely to dispute the work. Chase within 60 days.

Next step

If the deadline passes, lodge with VCAT, QCAT or your state’s small claims court. In New South Wales, lodge in the Local Court, not NCAT: the Small Claims Division up to $20,000 and the General Division over $20,000 up to $100,000. Bring your engagement letter, invoices and lodgement confirmations as evidence.

What happens when you send a Letter of Demand

Same problem. What a prepared case looks like.

Before — doing it yourself
You text them. They ignore you.
You email again. "Sorry, been busy."
Weeks pass. Nothing changes.
You start to feel like the annoying one.
