ChatGPT prompts for bookkeepers: 20 copy and paste prompts for client emails, admin and social posts

The short version: ChatGPT is useful to bookkeepers for drafting client emails, chasing payment, writing quotes, replying to reviews and turning notes into social posts. It is not safe for anything involving a client's actual figures, bank details, tax reference numbers or transaction history, since that is confidential financial data that should never be typed into a chat window. Below are 20 prompts you can copy today, plus a clear line on what never goes near the tool.

Quote and pricing email prompts

A pricing email that sounds unsure loses the client before they even see the number. These prompts help you write a confident quote without ChatGPT ever seeing the client's real turnover or figures.

1. "Write a quote email for monthly bookkeeping services for a business with [number] transactions a month, priced at [price] per month, including VAT returns and payroll for [number] staff."
2. "Write an email explaining why our bookkeeping package costs more than a competitor quoting [lower price], focusing on turnaround time and year end support."
3. "Write a follow up email to a prospect who received a quote 5 days ago and has not replied, offering a 15 minute call to answer questions."
4. "Write an email presenting three pricing tiers for bookkeeping services, basic, standard and full service, each with a short list of what is included."

What to change: the price, the number of transactions, and the specific service included. Use placeholder numbers like [price] in the prompt itself, then fill in the real figure only in the final email, never inside the ChatGPT conversation if you are pasting real client data anywhere near it.

Payment reminder and chasing email prompts

1. "Write a friendly first reminder email for an invoice that is 3 days overdue, no late fee mentioned yet."
2. "Write a firmer second reminder for an invoice that is 14 days overdue, mentioning that a late payment fee applies after 30 days."
3. "Write a final notice email for an invoice that is 45 days overdue, stating that work will pause on the account until payment is received."
4. "Write a short email asking a client to confirm receipt of documents needed to complete their VAT return before a deadline."

Keep the invoice number, client name and amount out of the ChatGPT prompt itself. Write the email with placeholders like [amount] and [invoice number], then fill those in yourself in your email client where the data stays private to that thread.

Client onboarding and admin email prompts

1. "Write a welcome email for a new bookkeeping client explaining what documents we need in the first month and how our monthly process works."
2. "Write an email asking a client to switch to a specific accounting software, explaining the benefit without sounding like we are pushing extra cost."
3. "Write a checklist email listing everything a small business owner needs to send us before their year end accounts can be completed."
4. "Draft an email explaining a change to our fees for the new financial year, giving 60 days notice, tone: matter of fact, not apologetic."
5. "Write a short message asking a long standing client to move to a fixed monthly fee instead of hourly billing, explaining the benefit of predictable costs."

Review reply prompts

1. "Write a reply to a five star Google review from a client who says we saved them hours every month and caught an error their previous bookkeeper missed."
2. "Write a reply to a three star review from a client who felt communication was slow during a busy period, acknowledging the point without discussing their account details."

Never mention a client's name, business name or any figure from their account in a public review reply, even if the reviewer named themselves. Keep the reply general and move any specific discussion to a private message or call.

Social post prompts

1. "Write a LinkedIn post explaining one common bookkeeping mistake small business owners make with expense claims, written for someone with no finance background."
2. "Write a short social post reminding small business owners of an upcoming tax deadline, without giving specific tax advice."
3. "Write a LinkedIn post sharing a general lesson learned from working with small business clients, without naming any client or figure."

Admin and internal reporting prompts

1. "Turn these bullet points about this month's client work into a short internal summary for my team: [paste bullet points, no client financial data]."
2. "Write a template message to ask a client for missing receipts each month, so I can reuse it without rewriting it every time."

Bank reconciliation and software set up prompts

1. "Write a step by step email explaining to a client how to export a bank statement from their online banking app so we can complete their reconciliation."
2. "Write an email explaining the benefit of moving from spreadsheets to cloud accounting software, aimed at a client who is nervous about learning new software."
3. "Write a short troubleshooting message for a client whose bank feed has stopped connecting to their accounting software, with three things to try first."

These prompts are safe because they describe a process, not a client's actual numbers. Keep it that way: describe what needs to happen, and let the client supply their own figures directly into the software rather than through you typing them into a chat window.

A weak prompt versus a strong prompt

Weak: "Write a payment reminder email." This produces a flat, generic email with no sense of how overdue the invoice is or what happens next, which makes it easy for a client to ignore.

Strong: "Write a firm but polite second reminder email for an invoice that is 14 days overdue. Mention that a 3 percent late payment fee applies after 30 days under our terms, and offer a payment plan if cash flow is the issue. Tone: professional, not aggressive." The strong version gives ChatGPT the stage of the chase, the consequence, and an alternative, so the draft needs almost no rewriting.

Mistakes to avoid, and never paste client financial data

The biggest mistake bookkeepers make is pasting real client figures, bank statements, transaction lists, National Insurance numbers, UTRs or VAT registration numbers into ChatGPT to get help interpreting them. This is confidential financial data covered by your engagement letter and your professional body's rules, and once it is typed into a chat window you cannot fully control where it goes. Use ChatGPT only for the wording around the numbers, never the numbers themselves. If you need help understanding a transaction pattern, describe it in general terms, such as "recurring monthly software subscription," rather than pasting the actual line from a statement.

Other mistakes: trusting a ChatGPT explanation of a tax rule as final advice, when tax rules change and vary by business structure, so always check against HMRC guidance or your own professional knowledge before telling a client anything; sending a payment reminder that ChatGPT has made too soft, since it tends to add apologetic language that undercuts the point of a chasing email; and using identical wording across every client review reply, which reads as copied when a prospect checks your reviews before hiring you; and forgetting that a client onboarding email is often the first thing that sets expectations about deadlines, so a vague list of documents needed leads to chasing them again a week later for the same paperwork.

Frequently asked questions

Is it safe to paste a client's bank statement into ChatGPT to categorise transactions?

No. A bank statement contains an account number, sort code, balance and full transaction history, which is sensitive financial data you have a duty to protect. Use your accounting software's own categorisation tools instead, and keep ChatGPT for the email and admin side of the job.

Can ChatGPT replace a bookkeeper's judgement on VAT or tax questions?

No. It can explain general concepts, but tax rules depend on the specific business, its structure and current HMRC guidance, and getting it wrong has real financial consequences for the client. Treat anything tax specific as a starting point to verify, not an answer to repeat.

Will a client notice if I use ChatGPT to write their emails?

Not if you edit the draft to sound like you and add the real details yourself. Clients notice generic, unspecific emails far more than they notice good writing, so the fix is always to personalise the draft, not to avoid the tool.

How do I write a chasing email that gets paid faster?

State the amount, the days overdue and the consequence clearly, and give one easy way to pay or discuss it. A vague, over polite reminder gets ignored more than a short, specific one that names the number and the deadline.

Should I use ChatGPT to write my pricing page or quotes?

Yes for the wording, but you set the actual prices based on your own costs and the client's complexity, never let ChatGPT invent a number. Use placeholders in the prompt and fill in your real pricing afterwards. A pricing page written this way tends to read more clearly than one written from scratch under time pressure, simply because the structure is already sound before you add your own numbers and tone.
