Last week I wrote about what ChatGPT is and is not. The most common follow-up I got was some version of "I tried it and the output was generic garbage". Almost every time, the person had typed something like "write a promotion for my store" and received exactly what that prompt deserved.
Learning how to write prompts for business tasks is not a mystical skill, whatever the self-declared prompt gurus on LinkedIn suggest. It is the same skill as briefing a smart new hire on their first day: someone intelligent and fast, who writes well, but knows absolutely nothing about your company, your customers, or what "good" looks like to you. Brief them poorly and you get generic work. Brief them properly and you get a usable draft in thirty seconds.
This guide gives you the one structure you need, plus copy-paste templates for the three tasks business owners actually use this for.
The mental model: a smart hire with zero context
Imagine a capable fresh graduate starts at your company this morning. You say: "Write a promotion for my store." What do they not know?
- What the store sells and at what price point
- Who the customers are
- What the promotion actually offers
- Where the text will appear: Instagram caption, WhatsApp broadcast, printed banner
- How long it should be and what tone your brand uses
They would have to guess all of it, so they would produce something safe and bland. ChatGPT is that hire, except it cannot walk to your desk and ask. Everything it needs must be in the prompt, because the prompt is the entire briefing.
Once you internalize this, prompt quality stops being about magic words and starts being about complete briefings. That is a skill you already have.
The four-part structure: context, task, format, example
Every effective business prompt I write contains these four parts, usually in this order.
1. Context. Who you are, what the business is, who the audience is. Two or three sentences.
"I run a bakery in Tangerang with two branches. Customers are mostly families and office workers ordering via WhatsApp. Our tone is warm and casual, not corporate."
2. Task. The specific thing you want, including the goal behind it.
"Write a WhatsApp broadcast message announcing our new year promotion: buy two boxes of pastries, get one free, valid until January 31."
3. Format. Length, structure, language, and any constraints. This is the part everyone skips and the reason outputs disappoint.
"Maximum 80 words, in Indonesian, friendly tone, with one emoji at most, ending with a clear call to order via WhatsApp."
4. Example. When you have one, show a sample of past output you liked. One example teaches tone better than ten adjectives.
"Here is a past message customers responded well to: [paste it]. Match this style."
Skip the example when you have none, the other three parts still get you most of the way. But when output tone feels off, adding an example fixes it faster than any other adjustment.
Three templates to copy and adapt
Template 1: the difficult email
I am the owner of [business type]. I need to email [who] about [situation, including relevant history and amounts]. The relationship matters and I want to stay firm but polite. Write 3 versions in [language]: one direct, one softer, one very short. Each under 150 words.
The three-version trick matters. Asking for one email invites you to accept it passively. Three versions force a comparison, and you will usually combine the best parts, which keeps you in the editor's seat where you belong.
Template 2: the offer or promotion
I run [business] selling [products] at [price range] to [customer type]. I am promoting [exact offer with dates and terms]. Write [number] variations of [format: IG caption / WA broadcast / flyer headline], each [length], in [language], tone [describe or paste an example]. The main point to emphasize is [the one thing].
Note "the one thing". Given no priority, ChatGPT emphasizes everything equally, which is how you get promotional mush.
Template 3: the analysis assistant
I will paste [type of document or data below, with no confidential details]. Act as an experienced [role: retail operations consultant, HR manager, etc]. Summarize the main points in 5 bullets, then list 3 risks or problems I might be missing, then ask me 3 questions that would sharpen the analysis. [Paste material.]
That last clause, asking it to ask you questions, is the single most underused prompting move. It flips the tool from answer machine to thinking partner, and its questions are often better than its answers.
Iterating: the second prompt matters more than the first
Nobody writes the perfect briefing on the first try, and you do not need to. The conversation format exists precisely so you can steer:
- "Shorter. Half the length."
- "Too formal. Write it the way a friendly shop owner talks to a regular customer."
- "Version 2 is closest. Keep that structure but make the opening line about the deadline."
- "Now translate it to English, keeping the tone."
Treat the first output as a draft to be directed, not a verdict on the tool. Two or three steering messages typically get you from 60% to 90%. The last 10% is your edit, and it should stay your edit, because that is where your judgment and your facts come in. As I covered in What ChatGPT Actually Means for Your Business, the tool invents details confidently, so every number, date, and claim in the final text must come from you.
Three habits that keep you out of trouble
- Never paste confidential data. Customer lists, financials, contracts, employee data. Describe situations in general terms instead. The templates above are all written to work without secrets.
- Verify every fact. ChatGPT supplies structure and fluency. You supply truth. If it added a statistic or a regulation you did not give it, delete it or verify it independently.
- Save your winning prompts. When a prompt produces something good, save it in a document with a name like "WA promo prompt". Within a month you will have a small library tuned to your business, and your team can use it too. This is also the moment to think about ground rules for staff use, which I will cover in a future piece on writing an AI usage policy before your staff writes one for themselves.
The takeaway
Prompt writing is briefing. Context, task, format, example, then steer with follow-ups and finish with your own edit. No secret keywords, no guru course required.
Your homework is one real task: take an email or promotion you need to write this week anyway, spend three minutes writing a proper four-part briefing, and compare the result against what "write a promotion for my store" gave you. That comparison will teach you more than this article did, and the skill compounds from there, because every tool in this new wave of AI responds to exactly the same discipline: garbage briefing in, garbage draft out. Good briefing in, thirty seconds to a usable draft.
