A good software brief is not a technical document. It is a clear description of a problem, written by someone who understands their business, for people who understand software. Getting it right before you approach any agency or developer is the single most effective thing you can do to improve the quality of what you receive back.

The quality of proposals, estimates, and ultimately the software you receive is almost entirely determined by the quality of the brief you send. Vague briefs produce optimistic estimates that balloon once real complexity is discovered. Specific briefs produce accurate proposals, realistic timelines, and projects that deliver what was promised.
This guide walks through exactly what a useful software brief contains and includes a template you can use immediately.
1. What a brief actually needs to do
A software brief has one job: give the person reading it enough context to understand your problem, your constraints, and your definition of success without requiring them to ask twenty clarifying questions before they can begin thinking about a solution.
It does not need to specify the technology. It does not need to describe the architecture. It does not need to be long. A brief that takes thirty minutes to write and answers the right questions will produce better results than a fifty-page requirements document that took three weeks and still leaves the fundamental question, what problem are we solving? unanswered.
The test of a good brief
Hand your brief to someone who knows nothing about your business or your project. If they can explain back to you what problem is being solved, who will use the system, and what success looks like, the brief is good enough. If they cannot, keep working on it before sending it to an agency.
2. What to include section by section
The problem statement
One paragraph. What is the current situation, why is it a problem, and what would a solution make possible. This is the most important section and the one most briefs get wrong they describe the solution they have already decided on instead of the problem they are trying to solve. Start with the problem, every time.
The users
List every type of person who will use the system. For each one, describe the two or three most important things they need to be able to do. This is not a feature list it is a user needs list, and the distinction matters. Features are solutions. User needs are the problems those features solve. Agencies that understand the user needs will build better features than those handed a feature list and told to execute it.
The integrations
List every external system the new software needs to connect to: CRMs, accounting platforms, payment gateways, industry-specific databases, government APIs. For each one, note whether you know it has an accessible API and whether you have credentials or documentation available. Integration work is consistently the most underestimated cost driver in software projects; surfacing it in the brief allows it to be scoped properly.
The constraints
Non-negotiable requirements that must be met regardless of cost or timeline: regulatory compliance, data residency requirements, accessibility standards, a hard launch date tied to an external commitment. Constraints known upfront are designed around. Constraints discovered mid-build cause expensive rework.
The success criteria
How will you know the project has delivered what it should? Specific, measurable outcomes are far more useful than “it works.” “Field technicians complete job reports in under five minutes” is a success criterion. “The app is intuitive” is not.
The explicit out-of-scope list
What are you not building in this phase? This section is the one most people skip, and it is the one that prevents the most scope creep. Listing what is deferred sets a clear boundary that protects both the timeline and the budget of the first phase.
Budget and timeline
Share a range, even a broad one. Agencies that know your budget will propose the best possible solution within it, not the most expensive thing they can justify. A timeline with the reason behind it (a product launch event, a contract start date) is more useful than a date alone, because it tells the agency which constraints are hard and which might have flexibility.
3. A reusable template you can fill in today
Software Project Brief Template
1. The problem we are solving
Describe the current situation in one or two sentences. Why is it a problem? What does it prevent your business from doing, or what does it cost in time, money, or quality? What would become possible if this problem were solved?
2. Who will use it
List each user type (e.g. “field technician”, “office admin”, “client”). For each, list the 2–3 most important things they need to be able to do with the system. Focus on what they need to accomplish, not what buttons they will click.
3. Systems it needs to connect to
List every external system the software needs to talk to. For each: name the system, describe what the integration needs to do (read data, write data, trigger actions), and note whether you have API documentation and credentials available.
4. Non-negotiable constraints
List anything the system must do or must not do, regardless of cost or timeline. Include regulatory requirements (GDPR, HIPAA, FCA), data residency rules, accessibility standards, security certifications, or hard launch dates with the reason behind them.
5. How we will know it has worked
Define 2–3 specific, measurable outcomes that would tell you the project has delivered what you needed. Avoid subjective criteria like “easy to use” aim for “task X completed in under Y minutes” or “volume of manual process Z reduced by N%.”
6. What is explicitly out of scope
List the features, integrations, or user types you are deliberately not including in this phase. Note why each is being deferred this protects the scope boundary and helps the agency build toward future phases without creating technical debt.
7. Budget range and timeline
Provide a budget range you are comfortable sharing. Note your target go-live date and the reason behind it. If the date has flexibility, say so. If it is tied to an external commitment (event, contract, regulatory deadline), make that clear.
8. Decision maker
Name the person on your side who has authority to make decisions about scope, design, and budget during the project. This person should be available to respond to questions within 24 hours during the build phase.
4. Brief vs bad brief real examples
✗ Weak brief
“We need a mobile app for our field team to manage jobs. It should be easy to use and connect to our systems. We need it as soon as possible.”
✓ Strong brief
“Our field technicians currently complete paper job sheets on site and hand them to the office for manual entry into ServiceMax. This takes 48 hours and introduces errors. We need a mobile app that lets technicians complete job reports on site, attach photos, and capture a customer signature with data syncing to ServiceMax in real time. Launch must be before 1 March due to a client contract.”
✗ Weak problem statement
“We want to build a customer portal where clients can log in and see their account information.”
✓ Strong problem statement
“Our account managers spend approximately six hours per week answering status enquiries that clients could resolve themselves if they had access to their project timeline, invoice history, and document library. A self-service portal would free that time and reduce client-reported satisfaction issues around responsiveness.”
5. Common mistakes and how to fix them
- Writing a solution instead of a problem. “We need an app that does X” describes a solution. “Our team loses Y hours per week because Z” describes a problem. Start with the problem, and agencies will propose better solutions than the one you have already decided on.
- Leaving out the integrations. “It just needs to connect to our CRM” is not enough. Name the CRM, describe what the integration needs to do, and note what access you have. Integration complexity is the most common source of budget overruns and missed timelines.
- No success criteria. Without measurable outcomes, neither you nor the agency has a clear definition of done. Subjective criteria (“easy to use”, “fast”) lead to disputes at the end of the project. Define what success looks like in terms that can be measured.
- Omitting the out-of-scope list. What you are not building is as important as what you are. Without a clear boundary, everything is potentially in scope and scope creep is the most reliable way to miss a deadline and overspend a budget.
- Not naming a decision maker. Every project generates questions that need timely answers. If there is no named person with authority to answer them quickly, decisions pile up and the project stalls. Name one person before work begins.
At SmartWayLabs, when we receive a well-written brief, our discovery process takes half the time because the fundamental questions are already answered and we can focus on the technical and integration details rather than extracting basic context. When we receive a weak brief, the first thing we do is work through these sections with the client before producing any estimate. The brief is always worth the time it takes to write properly.
The bottom line
A software brief does not need to be long, technical, or perfectly formatted. It needs to answer eight questions clearly: what problem are you solving, who are the users and what do they need to do, what does it connect to, what are the constraints, how will you measure success, what is out of scope, what is the budget and timeline, and who makes decisions.
Answer those eight questions honestly and specifically, and you will receive better proposals, more accurate estimates, and significantly smoother projects than the majority of clients who approach agencies with a vague idea and a tight deadline.
If you have a brief you would like a second opinion on before sending it out or if you would rather work through it together with people who have reviewed hundreds of them, the SmartWayLabs team is happy to help. Send us what you have and we will tell you honestly what is missing and what is strong.
