ChatGPT prompts for customer service: 34 copy-paste prompts for replies, complaints, summaries and FAQs

These prompts are for the owner or staff member who answers customers and wants a faster first draft. Each one is ready to paste: replace the parts in square brackets, keep the instructions, and edit the result before you send it. Read the privacy rules first; they take two minutes and keep your customers' details out of places they should not be.

Before you paste: the privacy rules

Remove personal details from every message before it goes into ChatGPT, and check your account's training setting once. That covers most of the risk.

According to OpenAI's data controls page (read 17 October 2026), conversations on personal plans can be used to train its models unless you turn off "Improve the model for everyone" under Settings, Data controls. Temporary chats are not used for training and may be kept for up to 30 days for safety. Business, Enterprise and Edu workspaces are not used for training by default. Rating a response with thumbs up or down can make that whole conversation available for training, so avoid rating chats that contain customer content. Your local data protection law may set further limits; see our customer data safety guide.

The four-part prompt skeleton

Every prompt below follows the same shape. Once you know it, you can write your own in a minute.

Adding your real facts (price list, policy, hours) to the input is what turns a generic answer into a usable one. Without them, ChatGPT fills the gap with typical figures from the internet, which may not be yours.

Prompts for drafting replies (1 to 8)

For everyday questions where you know the answer but want it worded well and fast.

1. Quick answer: "You are the owner of [business]. Using only these facts: [facts], draft a WhatsApp reply under 50 words to: [message]. End with one question that moves them toward booking."
2. Price question: "Draft a friendly reply to a customer asking the price of [service]. Our price is [price], which includes [inclusions]. Mention one thing that makes it good value without exaggerating. Under 60 words."
3. "Is this still available?": "A customer asked if [item] is still available. It is [available / sold out, similar item is X]. Write a reply under 40 words that answers and invites the next step."
4. Booking offer: "Write a reply offering these two times: [time 1], [time 2], and asking which suits. Polite, short, no exclamation marks."
5. Follow-up after silence: "A customer asked about [service] two days ago and did not reply to our answer. Write one gentle follow-up, under 35 words, that is easy to ignore and does not pressure them."
6. Reply in their language: "Translate this customer message into English, then draft my reply in the same language and style they used: [message]. Our answer is: [answer]."
7. Polite no: "We do not offer [service]. Draft a kind reply that says so clearly, suggests [alternative or where to go], and keeps the door open. Under 50 words."
8. Out of hours: "Write a reply for a message received at [time] when we are closed. Say when we open, answer this if possible: [question], and say a person will confirm in the morning."

Prompts for complaints and refunds (9 to 14)

These are where ChatGPT helps most, because it stays calm when you might not. Decide the outcome yourself before you prompt; never let the draft promise a refund or discount you have not approved.

Prompts for summarizing and triage (15 to 19)

Useful when a thread is long, a colleague is taking over, or the inbox is full after a weekend.

15. Three-line summary: "Summarize this conversation in three lines: what the customer wants, what we have promised, what is still open. [thread]"
16. Handover note: "Write a handover note for a colleague taking over this case: background, current status, next step, and anything they must not say. [thread]"
17. Sort a backlog: "Here are [number] redacted customer messages. Group them into: urgent complaint, booking request, price question, other. List the urgent ones first. [messages]"
18. Find the real question: "This customer wrote a long message. What is the one thing they actually need from us? [message]"
19. Sentiment check: "Rate how upset this customer is from 1 to 5 and explain why in one sentence, so I know how quickly to reply. [message]"

Prompts for FAQs and knowledge (20 to 25)

These turn the questions you keep answering into content your website, staff or AI agent can reuse. They pair well with our guide to writing a business FAQ.

20. Questions to FAQ: "Here are customer questions from the last month: [list]. Group duplicates, then write each as a clear FAQ question in the customer's words."
21. Rough answers to clean answers: "Rewrite these answers so each is under 50 words, states the fact first, and includes any condition: [Q&A list]. Do not add facts I did not give you."
22. Find gaps: "Here is our FAQ: [FAQ]. Here are recent questions: [questions]. Which questions are not answered by the FAQ?"
23. Plain-English policy: "Rewrite our cancellation policy so a customer understands it in one read. Keep every rule; remove legal padding: [policy]"
24. Price list cleanup: "Turn this price information into a table with columns: item, price, what is included, conditions: [text]. Flag anything unclear instead of guessing."
25. Q&A pairs for an AI agent: "Turn this page into question and answer pairs, one fact per answer, written the way customers ask: [page text]"

Prompts for templates and tone (26 to 30)

Draft once, save as quick replies, reuse for months.

26. Template set: "Write five short WhatsApp reply templates for a [business type]: greeting, price enquiry, booking confirmation, reminder, thank you. Leave [brackets] for details."
27. Tone match: "Here are three replies I wrote that sound like us: [examples]. Rewrite this draft in the same voice: [draft]"
28. Shorten: "Cut this reply to under 40 words without losing any fact: [reply]"
29. Warmer, not longer: "Make this reply warmer without making it longer or adding emoji: [reply]"
30. Local style: "Rewrite this reply the way a friendly shop in [city] would write on WhatsApp, using common local phrasing but keeping it professional: [reply]"

Prompts for reviewing your service (31 to 34)

Once a month, paste a sample of redacted conversations and ask for an honest critique.

31. Reply audit: "Review these replies for speed of answer, clarity and tone. List the three biggest problems and a fix for each. [replies]"
32. Missed sales: "In these conversations, where did the customer show buying intent that we did not follow up? [threads]"
33. Repeat questions: "Which questions appear more than once here, and what single page or message would stop them? [messages]"
34. Escalation rules: "Based on these conversations, suggest rules for when a message should go to the owner instead of being answered by staff. [threads]"

You will not need all 34 every week. Most owners settle on five or six they use daily and keep the rest for the hard days.

A worked example

Here is prompt 9 in use, with a hypothetical salon. The customer's message (redacted): "I paid for a full color and it's patchy. Booked with [NAME] on Saturday. Very disappointed, this was for a wedding."

The difference is not clever wording. It is giving the facts and the decision, and setting limits.

When prompts are not enough

Prompts make each reply faster, but a person still copies every question in and every answer out. When most of your messages are repeat questions, or they arrive while you are asleep or with a customer, that routine becomes the bottleneck. That is the point to look at a customer-facing agent; our explainer on ChatGPT for customer service sets out the difference.

ReplyKit is one such agent. It answers WhatsApp and website chat directly from your own content (the FAQs and price tables these prompts help you write can go straight into its knowledge), says so and alerts you when it does not know, books real open slots, and lets you take over any chat in one click. It costs $29 to $99 a month with AI replies included; see pricing or start a free trial. It is not the right choice if you want to keep writing every reply yourself, or if your messages are mostly complaints, which deserve a person anyway.
