How do you write a good ChatGPT prompt for business?
A good business prompt has four parts: who the AI should act as, what to do and not do, an example of the output you want, and your own facts pasted in. That order comes from OpenAI's prompt engineering guide for its API, which suggests a message with Identity, Instructions, Examples and Context sections, with context usually best placed near the end. OpenAI's ChatGPT help article on prompting adds three habits: be clear and specific with enough context, refine the prompt after you read the first answer, and name the tone you want with words such as formal, friendly or professional.
| Part | What to write | Example line |
|---|---|---|
| Identity | The role and the reader | You are helping the founder of a 5-person IT support firm write to clinic managers. |
| Instructions | The task, length, tone and what to avoid | Write one email under 120 words, friendly and plain. No discounts, no claims we can't prove. |
| Examples | One or two things you wrote that worked | Here is a follow-up I sent last month that got a reply: [paste] |
| Context | Your notes, their words, the facts | Call notes: [paste]. Our price: [paste]. |
The OpenAI guide also suggests Markdown headings and XML-style tags to mark where one piece of pasted text starts and ends. In ChatGPT that can be as simple as typing <notes> before your call notes and </notes> after them.
Which ChatGPT prompts help with sales and marketing?
These are example prompts. We wrote them from OpenAI's guidance; we haven't tested them or measured results. Replace every bracket with your own facts. Northwind Ltd and Priya at Acme are sample names.
Prompts 1 and 4 tell the model what to do when a fact is missing, so a guess shows up as a marked gap you can fill. For the proposal structure behind prompt 4, see our guide to writing a proposal that gets signed. For posts that sound like you rather than like everyone else, our guide on getting ChatGPT to write LinkedIn posts in your voice shows how to feed it samples.
How do you give ChatGPT context and get better output?
Paste the facts, ask for one narrow job, then read the first answer and change one thing at a time. That is the iterative refinement OpenAI's help article describes: start with a prompt, review the response, then adjust the wording, add context or simplify.
- Give it your words, not your summary. Paste the customer's email or your raw call notes. A summary you wrote already loses the phrases the buyer used.
- Keep reusable parts at the top. If you send the same role and rules every time, keep them first and paste the changing material last, which matches the order OpenAI's API guide suggests.
- Show one example. OpenAI's guide calls this few-shot learning: a handful of input and output examples in the prompt, which the model picks up as a pattern. It suggests examples that show a range of inputs.
- Ask it to flag gaps. A line such as "write [MISSING] instead of guessing" turns an invented fact into a visible gap.
On paid individual plans, OpenAI's pricing page lists Projects, scheduled tasks and custom GPTs under Plus, so you can keep your role, rules and examples in one place instead of pasting them into every chat. A tighter prompt still won't find buyers for you; our post on why ChatGPT marketing often gets no users covers that gap.
Does ChatGPT use your business data for training?
On ChatGPT Free, Plus and Pro, OpenAI may use your conversations to train its models unless you opt out. On ChatGPT Business, Enterprise and Edu, and on the API, it doesn't by default. That is what OpenAI's help article on how your data is used to improve model performance says (checked 5 Nov 2026).
| Free, Plus, Pro (individual) | Business, Enterprise, Edu, API | |
|---|---|---|
| Training on your content | May be used; you can opt out | Not used by default |
| How to opt out | Settings, Data controls, turn off Improve the model for everyone (or use OpenAI's Privacy Portal) | No action needed |
| Thumbs up or down | The whole conversation may be used for training, even after you opt out | Doesn't permit training on that conversation (Business, Enterprise, Edu) |
| Temporary chats | Not used to improve models while they stay temporary | Not covered separately on this page |
OpenAI's enterprise privacy page (updated 8 January 2026) adds that for business plans and the API you own your inputs and outputs where allowed by law, and that OpenAI completed a SOC 2 audit. The practical rule for a small team: don't paste customer contracts, personal data or anything under NDA into a personal account that still has training switched on.
How much does ChatGPT cost for a small business?
ChatGPT Plus costs $20 a month, billed monthly, according to OpenAI's Plus help article, which also says there is no annual billing for Plus. ChatGPT Business is billed per seat. OpenAI's Business billing help page (checked 5 Nov 2026) lists the Business seats; the other rows are from the pricing page and the Plus article:
| Plan | Price | Billing basis |
|---|---|---|
| Free | $0 | For individuals |
| Plus | $20 a month | Per person, billed monthly |
| Business, Standard seat | $25 per user a month, or $20 per user a month billed annually | Usually 2 paid seats; some new workspaces can start with 1 |
| Business, Premium seat | $125 per user a month, or $100 per user a month billed annually | Higher usage limits than Standard |
| Enterprise | Not listed | Contact sales |
When we opened the pricing page from India, Business showed in rupees and the individual plan prices didn't display, so check the page in your own country. Its FAQ says Free, Go and Plus are designed for individuals and Business is for businesses, starting at 2 users.
Worked example: a 3-person team. Three Plus accounts cost 3 x $20 = $60 a month, or $720 a year, and each person has to opt out of training themselves. Three Standard Business seats cost 3 x $25 = $75 a month on monthly billing ($900 a year), or 3 x $20 x 12 = $720 a year on annual billing. On annual billing, Business costs the same as three Plus accounts, and your inputs aren't used for training by default. Monthly Business costs $180 a year more than three Plus accounts ($900 - $720).
How do you fact-check what ChatGPT writes?
Check every number, name, quote and link before anything leaves your outbox. OpenAI's help article on whether ChatGPT tells the truth says it can produce incorrect definitions, dates or facts, fabricated quotes, studies or citations, and overconfident answers, and advises verifying quotes, data and references and visiting links directly. A five-minute checklist:
Circle every fact
Numbers, dates, prices, company names, job titles and quotes. Each one needs a source you can open.
Open each link
Click it and find the sentence it supports. A link that loads but doesn't say the thing doesn't count.
Compare with your notes
Anything about the customer that isn't in your notes or their own words comes out.
Check what you promised
Prices, dates and scope must match what you can deliver.
Read it aloud once
Cut any line you wouldn't say to the person on a call.
This week, take prompt 2, run it on your notes from your last sales call, and time how long the checklist takes on the draft. If account research is the slowest part of your week, Siela's Lead Finder looks for a reason to reach out now, such as hiring for the work you automate or a role change, and scores each lead hot, warm or cold with a one-line reason.
Frequently asked questions
What is the best ChatGPT prompt for a small business?
There isn't a single best one. Useful prompts give the model one narrow task, your own pasted facts and an example of the result you want, then tell it what to do when a fact is missing. Account research and call follow-ups are good places to start because you can check the output against your notes.
Is it safe to put customer information into ChatGPT?
It depends on the plan and your settings. OpenAI says Free, Plus and Pro conversations may be used for training unless you opt out, while Business, Enterprise and API data isn't used by default. Even then, check your own contracts and privacy duties before pasting personal data or anything under a confidentiality agreement.
Should a small team buy ChatGPT Plus or ChatGPT Business?
If two or more people use it for work, compare the totals. At OpenAI's listed prices, three Business Standard seats billed annually cost the same per year as three Plus accounts, and Business doesn't train on your inputs by default. Plus suits one person who is happy to manage their own data settings.
Can ChatGPT write sales emails that sound human?
It can draft them, but the parts that make an email feel human come from you: the buyer's own words, a real detail from your call and a specific next step. Paste those in, give one email you wrote yourself as an example, and edit the draft before sending rather than sending it as written.
Why does ChatGPT make up facts in business writing?
OpenAI's help centre says its models can produce incorrect facts, fabricated citations and confident answers that are wrong. It happens most when the prompt asks for detail you haven't supplied. Paste the facts yourself, ask the model to mark gaps instead of guessing, and verify every number and link before using the text.
