Requirements, written down
A requirements document your developers can build from without guessing
A PRD sets out what the product must do in terms a build team can execute and test: functional requirements, acceptance criteria, dependencies, assumptions and what's out of scope. We write it in plain language first, with the technical detail underneath for whoever builds it.
What you get
What’s included
Product overview
Problem, users and goals on one page, so anyone opening the document knows why the product exists.
Functional requirements
What each feature does, written as user stories or plain statements and grouped by area of the product.
Acceptance criteria
Pass or fail conditions for each requirement, so done means the same thing to you and to the developer.
Dependencies
Outside services, integrations, content and decisions the build relies on, listed so none of them surprise anyone mid-build.
Assumptions
What the requirements take to be true, written down so they can be checked.
Out-of-scope calls
What this version will not do, recorded so it doesn't creep back in halfway through the build.
A good fit if
- Founders handing a build to an agency or freelancer who want fewer disputes later
- Teams whose last build went wrong because the agreement lived in calls and chat threads
- Products adding a large feature, like class booking, payments or a coach dashboard, to an existing app
- Founders who need a written spec to get quotes they can compare
Not included
- Designs or wireframes
- Architecture or technology decisions (see technical discovery)
- A build estimate
How it runs
From kickoff to handover
- Step 1
Gather
We collect your scope, flows, notes and any existing documents, and list what's still undecided.
- Step 2
Draft
We write the requirements and acceptance criteria, area by area.
- Step 3
Question and revise
You review the draft and answer the open questions. We revise until nothing is left to interpretation.
- Step 4
Handover
You get the final PRD, ready to send to your developers or to agencies for quotes.
Questions
Questions about PRD / requirements document
What's the difference between a PRD and an MVP scope document?
The scope decides which features are in version one. The PRD says how each of those features behaves and how to test it. If scope isn't settled yet, start with the scope document or the sprint.
Can you write a PRD for one feature instead of a whole product?
Yes. A PRD for a single large feature, like adding memberships to an existing booking app, follows the same structure: requirements, acceptance criteria, dependencies, assumptions and exclusions.
Will my developers find it too high level?
Each requirement is written in plain language with the technical detail beneath it, and the acceptance criteria are specific enough to test against. If your developers have questions, that's usually a sign of an open decision, and the draft round is where it gets settled.
Who keeps the PRD up to date during the build?
You own the document and can update it yourself or have your developers do it. If you want us to keep requirements current through each build cycle, that's part of fractional product planning.
How much of my time does it take?
Enough to make decisions. We do the drafting. Your part is answering questions and reviewing the draft, and the faster the answers come back, the faster the document is finished.
