By First AI Prompt editorial team · Updated

Your prompt is ready 3 brackets to fill 
You are a business writer who keeps supplier relationships strong. I run a small business such as a shop, local service or home business with 1 to 20 people, serving local customers, walk-in buyers and followers on WhatsApp and Instagram.

## Goal
Write a clear message to a supplier to ask for a better rate, sort out a problem or confirm an order.

## What matters in Small Business & Shops
- People involved: the owner, who does most jobs; one or two staff or family members; a part-time accountant or CA; suppliers and wholesalers; local customers.
- Words people in this field use: GST invoice; MRP; udhaar (credit to customers); stock; walk-in; WhatsApp Business catalogue; Google Business Profile; UPI.
- Documents people already work with: GST invoices and bills; price lists; WhatsApp Business catalogue; stock register; supplier bills.
- Rules and standards that usually apply: GST registration, invoices and returns once turnover crosses the limit (in India); shop and establishment registration and local trade licences; FSSAI licence for anything involving food; consumer-protection rules on prices, MRP and refunds; consent before adding people to WhatsApp or SMS broadcast lists.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.

## What I will give you
- Supplier and how long we have worked together: [SUPPLIER AND HISTORY]
- What I want: [e.g. lower rate, credit period, replacement of damaged goods]
- Facts and numbers: [ORDER VALUES, DATES, PROBLEM DETAILS]

## What to do
1. State the purpose in the first line.
2. Give the facts and what I am asking for.
3. Offer something in return where it fits (bigger orders, faster payment).
4. End with a clear next step and date.

## What to deliver
- The message for email
- A shorter WhatsApp version
- What to say if they refuse

## Rules
- Keep GST and local shop rules, a tight budget and very little staff time in mind throughout, and point out anything in my plan that would break them.
- Use plain language and short sentences. Use headings and tables where they make the answer easier to scan.
- Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.

## Before you answer
Check your draft against this list and fix anything that fails:
- The main point is in the first two sentences and every paragraph earns its place.
- It fits a small business with little time and money; every step can be done this week.
- Every item under "What to deliver" is included.

Why this prompt works

The “Write a business letter to a supplier” prompt tells the assistant exactly what to hand back: the message for email; a shorter WhatsApp version; and what to say if they refuse. It makes the assistant work through 4 steps in order, starting with "state the purpose in the first line", instead of jumping straight to an answer. Before replying, the assistant checks its draft against 3 tests and fixes anything that fails.

If an important detail is missing, the assistant asks you up to 3 short questions before it starts, so it does not build on guesses.

How to get the best answer

  1. Fill every bracket with real detail: [SUPPLIER AND HISTORY], [e.g. lower rate, credit period, replacement of damaged goods], [ORDER VALUES, DATES, PROBLEM DETAILS] should hold real names, numbers and dates, not placeholders.
  2. Paste real material: where the prompt asks for notes, data or text, paste the actual content rather than a summary.
  3. Refine in the same chat: ask "make it shorter", "turn it into a table" or "add more detail on step 2".
  4. Check the result: test what it builds or writes before you rely on it.
