The Small Business Prompt Formula

You tried it once. You typed "write an email to my customers about our new service," and what came back sounded like a bank. Too long, too cheerful, full of phrases like "we are thrilled to announce," and nothing like the way you talk to people. You deleted it and wrote the email yourself, and quietly decided AI was not for you.

The problem was not the tool. The problem was that the prompt left almost everything to guesswork. AI filled every gap with the most generic option available, and generic is exactly what you got.

This lesson gives you a five-part formula you can use for almost any business writing task. It takes a minute longer to write than a one-line prompt, and it saves you from rewriting the whole result.

The five parts

Every strong small business prompt answers five questions.

1. Who you are. Your business, what you sell, and where. This tells AI which world it is writing in. A landscaping company and a law office need very different emails.

2. Who the reader is. A long-time customer, a new lead, a supplier, a job applicant. The same message reads differently to each.

3. What you want. The actual task, stated plainly. "Write a reply," "summarize this," "give me ten ideas."

4. What it should look like. Format and length. An email under 120 words. Three bullet points. A text message. A table with two columns. If you do not say, you will usually get something longer than you wanted.

5. What to avoid. Words you never use, claims you cannot make, tones that are wrong for you. This is the part most people skip, and it does the most to make the result sound like you.

Here is the formula as a template:

I run [YOUR BUSINESS: what you sell, where you are].

The reader is [WHO WILL READ THIS and what they care about].

I want you to [THE TASK, in one or two plain sentences].

Format: [LENGTH, STRUCTURE, e.g. "email under 120 words" or
"3 bullet points"].

Avoid: [WORDS, CLAIMS, OR TONES TO STAY AWAY FROM].

If you need a detail I have not given you, write [DETAIL NEEDED]
instead of guessing.

Details:
[PASTE THE FACTS, NOTES, OR MESSAGE YOU ARE RESPONDING TO]

That line about [DETAIL NEEDED] matters. Without it, AI will often invent a price, a date, or a promise to complete the sentence. With it, you get a visible gap you can fill in yourself.

Worked example: a two-person landscaping company

Dev and his partner run a small landscaping company. A customer emailed asking why they have not been out to mow in two weeks. The honest answer: one of their mowers broke, a part is on order, and they are running behind.

Weak prompt:

Write a reply to a customer who is upset we missed their mowing.

What comes back is usually a long, stiff apology full of phrases like "we sincerely apologize for any inconvenience" and "we value your business." It may also promise things Dev cannot deliver, like a discount or a specific day, because nothing told it not to.

Strong prompt:

I run a two-person landscaping company doing weekly lawn care
for homes in a suburban area.

The reader is a customer of three years who is frustrated that
we have missed two weekly visits. She is reasonable but annoyed.

I want you to write a reply that apologizes plainly, explains
that one of our mowers broke and a part is on order, and tells
her we will be at her property this Thursday.

Format: an email under 120 words. Short sentences. Sign off
as "Dev".

Avoid: corporate phrases like "we apologize for any
inconvenience" or "we value your business". Do not offer a
discount or refund. Do not promise any date other than Thursday.

If you need a detail I have not given you, write [DETAIL NEEDED]
instead of guessing.

Her message:
"This is the second week nobody showed up. I'm paying for weekly
service. What is going on?"

The second prompt gets a short, human reply that sounds like a small business owner, gives the real reason, commits to one date, and stops. Dev still reads it before sending. He checks that Thursday is actually right and that the tone fits this particular customer. But he is editing a few words, not rewriting from scratch.

Here is the whole difference, side by side:

Iterate instead of starting over

Even a strong prompt rarely gets the draft exactly right the first time. The mistake is to throw it away and start a new conversation. The draft is useful material. Tell AI what to change, in the same chat, and let it revise.

Good follow-up instructions are specific:

• "Shorter. Cut it to four sentences."
• "Less apologetic. One 'sorry' is enough."
• "Keep the second paragraph exactly as it is and rewrite the first."
• "The phrase 'rest assured' does not sound like me. Replace it."
• "Give me two more versions: one warmer, one more direct."

Vague follow-ups like "make it better" or "try again" tend to produce a different draft with different problems. Say what was wrong, and the next version fixes that thing.

When you find yourself making the same correction over and over, move it into the "Avoid" line of your prompt. That is how a prompt gets better over time: each fix you make once becomes a rule you never have to make again.

It is also worth seeing how different AI models handle the same request. Paste your strong prompt into the Study AI Mastery Playground's compare mode and run it on two or three models side by side. You will often find one of them matches your voice more naturally for this kind of task.

Try this

Take 10 to 15 minutes and use one of the three tasks you picked in the last lesson.

1. Write the laziest possible one-line prompt for it. Run it and save the result.
2. Now write the full five-part version using the template above. Include the [DETAIL NEEDED] line. Run it.
3. Compare the two. Note what changed: length, tone, accuracy, anything invented.
4. Give the better draft two specific follow-up instructions to fix what is still off.
5. Add whatever you corrected to the "Avoid" line and save the finished prompt somewhere you can find it next week.

Before you use any version for real, read it as the customer would. Check every fact, date, and number against what you actually know.

What to remember

• Five parts: who you are, who the reader is, what you want, what it should look like, what to avoid.
• The "Avoid" line is what makes AI sound like you instead of a bank.
• Add a rule for missing details so AI flags gaps instead of inventing answers.
• Revise the draft with specific instructions in the same chat rather than starting over.
• Turn repeated corrections into permanent rules in your saved prompt.
• AI makes mistakes. Read and check anything a customer will see before it goes out.
