Write a full product requirements document for Small Business & Shops

Your prompt is ready 4 brackets to fill

You are a senior product manager, working with local customers, walk-in buyers and followers on WhatsApp and Instagram at a small business such as a shop, local service or home business with 1 to 20 people.

## Goal
Write a PRD engineers and designers can build from.

## What matters in Small Business & Shops
- How customers decide: most customers live or work nearby; they choose on trust, price, convenience and how well they are treated; word of mouth, Google reviews and WhatsApp matter more than ads; many pay by UPI and like asking questions on WhatsApp first.
- Numbers that matter: monthly sales; repeat customers; average bill value; profit margin per product; cash in hand at month end; Google rating and number of reviews; enquiries from WhatsApp and Instagram.
- 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.
- Tools commonly used: WhatsApp Business; Google Business Profile; Instagram; UPI apps and QR codes; billing apps such as Vyapar, Khatabook or Tally; Canva.
- 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
- Feature: [NAME AND IDEA]
- Users and problem: [WHO AND WHAT PAIN]
- Business goal: [GOAL]
- Constraints: [TIME, TECH, BUDGET]

## What to do
1. Describe the problem with evidence.
2. Define goals and success metrics.
3. Write user stories with acceptance criteria.
4. Describe user flows and edge cases.
5. List non-functional requirements, risks and open questions.

## What to deliver
- Complete PRD
- User story table
- User flow in Mermaid syntax
- Launch checklist

## 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.
- Where it fits, connect your recommendations to monthly sales and repeat customers.
- 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:
- Each feature is tied to a user problem and a measurable outcome.
- It is written for a small business such as a shop, local service or home business with 1 to 20 people; nothing in it would read the same for any other business.
- Every item under "What to deliver" is included.

Why use this Write a full product requirements document prompt?

This write a full product requirements document prompt is written for a small business such as a shop, local service or home business with 1 to 20 people. It tells the assistant who the answer is for (local customers, walk-in buyers and followers on WhatsApp and Instagram) and the limits it must respect: GST and local shop rules, a tight budget and very little staff time. That context is what turns a generic reply into one a Small Business & Shops team can use straight away.

Most people type a single line and get a generic answer back. This prompt gives the assistant the role, the context and the structure it needs, so the first answer is already close to what you would hand to your team. Because it is written for Small Business & Shops, it keeps the focus on what that industry measures: monthly sales and repeat customers.

How to get the best answer

Be specific in the brackets: real names, numbers and dates give a far better answer than placeholders.
Paste real material: where the prompt asks for notes, data or text, paste the actual content rather than a summary.
Refine in the same chat: ask "make it shorter", "turn it into a table" or "add more detail on step 2".
Check the result: review it against what you know about monthly sales and repeat customers before you share it.
