Product Requirements Document (PRD): Free Template and How to Write One

A product requirements document (PRD) describes what a product must do, who it's for, and how you'll measure success, so designers and developers can build and quote it without guessing. A good PRD for an app fits on a few pages: the problem, the users, the 3 to 5 core features with acceptance criteria, and what's out of scope.

Why a PRD saves you money

Developers can only price what they can see. Without a written PRD, every quote is a guess, and the gaps turn into change requests mid-build. A clear PRD lets you compare quotes fairly, and it's the document you point to when someone asks whether a feature was ever agreed.

Copy these sections into a document and fill them in. Short, specific answers beat long ones.

1. Overview: one paragraph on what the product is and why it should exist.
2. Problem: the specific pain, who has it, and how they solve it today.
3. Goals and success metrics: what must be true 90 days after launch (for example, 100 paying users or 50% of bookings made in the app).
4. Users: two or three user types, with what each needs to get done.
5. Core features: the 3 to 5 features for the first version, each written as a user story.
6. Acceptance criteria: for each feature, the checks that prove it works.
7. Out of scope: features you're deliberately leaving for later.
8. Platforms: web, iOS, Android, and any devices or browsers that must be supported.
9. Integrations: payments, maps, email, CRM or anything else it connects to.
10. Business model: how the product makes money, such as subscription, commission or one-time purchase.
11. Constraints: budget range, deadline, compliance needs and data rules.
12. Open questions: what you don't know yet and who will answer it.

How to write a product requirements document, step by step

1. Start with the problem and the user, not the features.
2. List every feature you want, then cut to the 3 to 5 that the product can't launch without.
3. Write each one as a user story: 'As a [user], I want to [action] so that [outcome].'
4. Add acceptance criteria a non-technical person could test.
5. Sketch the main screens or link to wireframes.
6. Have a developer review it for gaps and risks before you ask for quotes.

Common PRD mistakes

• Describing how to build it instead of what it must do.
• No 'out of scope' section, so everything stays in.
• Missing the business model, which changes the architecture.
• Vague goals such as 'easy to use' with no way to test them.

PRD template, filled in: a booking app example

Here's how the template reads for a simple product, a booking app for independent personal trainers. Notice how short each section is.

Writing good acceptance criteria

Acceptance criteria are the most useful part of a PRD and the part founders most often skip. They turn a feature from an idea into something you can check. Each one should be testable by a non-technical person with the app in their hand.

• Weak: 'Booking should be easy.' Strong: 'A returning client can book a session in 3 taps or fewer.'
• Weak: 'Payments work.' Strong: 'The client is charged when booking, gets an emailed receipt, and the trainer sees the payment within a minute.'
• Weak: 'Send reminders.' Strong: 'The client gets a push notification 24 hours and 1 hour before each session.'
• Weak: 'Handle cancellations.' Strong: 'Cancellations more than 24 hours ahead are refunded automatically; later ones are not.'

PRD vs Blueprint: when to write it yourself

Writing your own PRD is worth doing even if you later pay for scoping, because it forces decisions only you can make: who it's for, what's out, and how it makes money. What a founder usually can't add alone is the technical side: the architecture, the risks, and an accurate price and timeline. That's the gap our Technical MVP Blueprint fills. It takes your PRD (or your notes, if you don't have one), and returns a fixed build price, the tech stack, a risk assessment and a pricing and profitability plan in 7 business days. You can take it to any developer.

How to use your PRD once it's written

1. Send the same PRD to every developer you're considering, so quotes are comparable.
2. Ask each one what they'd cut or change. Their answers tell you more than the price.
3. Attach the final version to your contract as the agreed scope.
4. Use the acceptance criteria to approve each milestone before you pay for it.
5. Update it when you change scope, and record the price impact in writing.
