How to Prepare Software Requirements Before Hiring a Development Partner
When a software project goes over budget, the cause is rarely bad code. It is usually unclear requirements: two people picturing different things and discovering it halfway through the build. A little preparation before you speak to a development partner makes quotes more accurate and the project far smoother.
Start with the business objective
Before features, write down why the software should exist. What problem does it solve, for whom, and how will you know it worked? "Reduce order-entry time by half" or "let customers self-serve their invoices" is a useful objective. "Build an app" is not. Objectives help everyone decide what to include and what to leave out.
Identify your user roles
List everyone who will use the system and what each role needs to do. For example: customer, sales representative, warehouse staff, accountant, administrator. For each role note what they can see, create, change, approve and never touch. Missing roles are one of the most common causes of late surprises.
Describe the workflows step by step
A workflow is the path from a trigger to an outcome. Write each one in plain language, for example: customer places an order → sales confirms stock → warehouse picks → driver delivers → invoice is issued. Include exceptions, such as what happens when an item is out of stock or a payment fails. Real businesses live in the exceptions.
Write acceptance criteria
Acceptance criteria say how you will judge a feature as done. They turn opinion into a test. A good one is specific and checkable:
- "A sales rep can create a quote in under five minutes from a saved customer record."
- "An order above the approval limit cannot be confirmed until a manager approves it."
- "The monthly report matches the accounting total for the same period."
Know what belongs in a BRD and an FRD
These two documents are often confused:
- Business Requirements Document (BRD): why the project exists. Business goals, users, scope, constraints, risks and measures of success.
- Functional Requirements Document (FRD): what the system must do. Screens, rules, roles, data fields, integrations, notifications and reports, in enough detail to build and test against.
You do not need to write them perfectly alone. Bring what you have, and use a structured product discovery phase to turn it into documents you can approve. The result is yours to keep, whichever team builds it.
Gather the supporting material
- Sample spreadsheets, forms, invoices or reports you use today
- A list of existing systems the new software must connect to
- Examples of products you like, and what you like about them
- Your budget range, timeline and any fixed deadlines
- Who has final decision-making authority on your side
Separate must-haves from nice-to-haves
Rank every requirement as essential, important or later. This one habit produces a realistic first release and keeps the budget under control. If the full list is large, consider launching a focused first version, as described in our approach to MVP development.
