ChatGPT Prompts for Australian Bookkeepers: Save Hours Every Week

The difference between bookkeepers who find AI useful and those who don't often comes down to one thing: knowing how to ask. A vague prompt produces a vague result. A specific, well-structured prompt produces something you can actually use.

This guide gives you prompts that work for the real tasks Australian bookkeepers face every day — tested for Australian conditions, GST requirements, and the kinds of clients most practices work with.

How to Use These Prompts

Copy the prompt, replace the bracketed sections with your specific details, and paste into ChatGPT (GPT-4o) or Claude. Always review the output before sending to clients or using in official documents.

A few principles that make prompts work better:

Give context: Tell the AI who you are, who the client is, and what the situation involves. More context produces more relevant output.

Specify the format: If you want a bullet list, say so. If you want a formal letter, say so. If you want plain English, say so.

Iterate: If the first output isn't quite right, ask for adjustments rather than starting over. "Make it shorter" or "make it more formal" works well.

Client Communication Prompts

Monthly update email

You are an Australian bookkeeper preparing a monthly update email for a small business client. The client runs [type of business] in [state]. This month: [key financial highlights — e.g. revenue up 12%, outstanding invoices totalling $X, BAS due date approaching]. Write a professional but friendly email summarising the month and noting any action items for the client. Keep it under 200 words. Do not include specific dollar amounts in the subject line.

Overdue invoice reminder (first notice)

Write a professional, polite email reminding a client that invoice [number] for [amount] was due on [date] and remains unpaid. The client is [describe relationship — e.g. long-standing, new]. Tone should be firm but not aggressive. Include a clear call to action. Sign off as [your name], bookkeeper.

Overdue invoice reminder (second notice)

Write a firmer follow-up email for an invoice that is now [X] days overdue. The client has not responded to a previous reminder sent [X] days ago. Invoice number [X], amount [X], original due date [X]. Maintain professionalism but make clear that prompt payment is required. Mention that we may need to discuss payment arrangements if full payment is not possible.

Explaining a transaction categorisation

A client has questioned why their purchase of [item/service] was categorised as [category] rather than [what they expected]. Write a brief, clear explanation in plain English — no jargon — explaining the categorisation and why it's correct for Australian tax purposes. Keep it to 3–4 sentences.

Requesting missing documents

Write a professional email to a client requesting the following missing documents needed to complete their [month/quarter] bookkeeping: [list documents]. Explain why each document is needed in one sentence. Keep the tone helpful, not accusatory. The client tends to be [describe — e.g. busy and forgetful / responsive when given clear instructions].

BAS and Compliance Prompts

BAS preparation checklist

The business is [type] registered for GST. Include sections for: bank reconciliation, accounts receivable, accounts payable, payroll (if applicable), and document collection. Format as a checklist with checkboxes. Include a reminder about the lodgement due date.

Explaining BAS to a new client

Write a plain-English explanation of what a BAS is, why it needs to be lodged, and what information the client needs to provide to their bookkeeper each quarter. The audience is a new small business owner with no accounting background. Keep it under 300 words. Avoid jargon.

GST query response

A client has asked whether [specific purchase or transaction] includes GST and how it should be treated. Write a response explaining the general GST treatment for this type of transaction in Australia. Note that this is general information only and they should confirm with their bookkeeper or tax agent for their specific situation.

Reporting and Analysis Prompts

Monthly P&L summary for client

I will paste a profit and loss summary below. Write a 150-word plain-English summary of the key highlights for a small business owner. Note any significant changes from the previous period, flag any areas of concern, and end with one or two questions the client should consider. [Paste P&L data]

Cash flow commentary

Based on the following cash flow data for [month], write a brief commentary (100–150 words) explaining the cash position, any significant movements, and what the client should be aware of in the coming month. Use plain English. [Paste cash flow data]

Year-end summary letter

Write a year-end summary letter for a small business client covering the financial year [year]. Key points to include: [list key metrics and highlights]. The tone should be professional but warm. Acknowledge the client's efforts and note any areas to focus on in the coming year. Keep it to one page.

Internal Practice Prompts

Engagement letter template

Create an engagement letter template for an Australian bookkeeping practice. Include sections for: scope of services, fees and payment terms, client responsibilities, confidentiality, and termination. The practice is [name], located in [state]. Services include [list]. Keep the language professional but accessible. Note that this is a template requiring legal review before use.

Procedure documentation

Write a step-by-step procedure for [specific bookkeeping task — e.g. processing a client's monthly bank reconciliation in Xero]. The audience is a new staff member with basic bookkeeping knowledge. Include screenshots placeholders where relevant. Format as numbered steps with sub-steps where needed.

Client onboarding checklist

Create a client onboarding checklist for a new bookkeeping client. Include: initial information to collect, software setup steps, document collection setup, access permissions needed, and first-month tasks. Format as a checklist. The practice uses [Xero/MYOB] and [Dext/Hubdoc].

Tips for Better Results

Be specific about Australian context: Mention GST, BAS, ATO, or Australian-specific requirements when relevant. This helps the AI produce output that's appropriate for Australian conditions rather than generic international content.

Specify the audience: "Write for a small business owner with no accounting background" produces very different output than "write for a client who understands basic accounting."

Use follow-up prompts: After getting an initial response, try: "Make it more concise," "Add a more urgent tone," or "Include a specific call to action by [date]."

Save your best prompts: Keep a document of prompts that work well for your practice. Over time, you'll build a library that covers most common situations.
