You do not need to know what an API is to get good software built. You need to be clear about three things: the problem, the people who live with it, and what the world looks like once it is solved. Everything else, the stack, the architecture, the sprint plan, is the development team's job.
Most advice on how to write a brief for software developers assumes you already think like one. This guide assumes you do not, and that this is fine. Some of the clearest briefs we have ever received came from founders who could not name a single framework but knew their own operation cold. That knowledge is the raw material. Here is how to shape it.
Describe the problem, not the solution
The most common failure in a first brief is prescribing. "We need an app with a dashboard, user roles, and push notifications." That sentence feels productive, but it quietly hands the team your guess instead of your knowledge. You are the world expert on your problem. You are probably not the world expert on solving it in software, which is exactly why you are hiring people who are.
Compare two openings. Solution-shaped: "Build us a scheduling app." Problem-shaped: "Our dispatchers rebuild the driver schedule by hand every morning, because the plan and reality drift apart overnight, and the mistakes turn into missed pickups." The second version lets a good team propose something you would never have specified, often smaller and cheaper than the app you had in mind.
Across the 50 plus products we have shipped and still maintain at ETREXIO, we can usually trace scope creep back to a solution-shaped brief. When clients handed us problems, the software stayed small and lived long. Our average client relationship runs about five years, and the longest ones began with the plainest problem statements.
Write the user story in plain words
A user story is just a sentence that names a person, a moment, and a need. Forget the formal "as a user, I want" phrasing if it feels stiff. Use this shape instead:
When [a situation happens], [a specific person] needs to [do something], otherwise [what it costs].
For example: "When a customer emails to change a delivery address, our support lead needs to update it in one place, otherwise she edits three systems and one of them is always wrong."
Write five to ten of these, one per line, then rank them. Use real roles, even real first names if it helps you stay concrete. A developer reading a ranked list like this can see the shape of the system underneath it. No feature list gives them that.
Share the spreadsheet you are trying to kill
Almost every piece of internal software replaces something that already exists: a spreadsheet, a shared inbox ritual, a WhatsApp group, a paper form taped near the printer. That artifact is the best specification you own, because it encodes years of real decisions. The column someone turned red matters. The tab named "DO NOT TOUCH" matters most of all.
Attach it, and resist the urge to tidy it first. The mess is the information. If the workaround is a process rather than a file, record a short screen capture of yourself doing the painful task once, narrating as you go. Ten minutes of that footage is worth pages of description.
If the file contains sensitive data, redact the values but keep the structure. The team needs the columns, not the customers.
Define done before anyone writes code
Done is where most briefs go vague. Words like "modern", "intuitive", and "scalable" are wishes, not tests. Replace them with checkable sentences a stranger could verify. "This is done when a dispatcher can publish tomorrow's schedule without opening the old spreadsheet." "This is done when a new order appears in the driver's view without anyone forwarding a message."
Just as important is the not-now list. State explicitly what the first version excludes: invoicing, a mobile app, multiple languages, whatever you are consciously postponing. Deciding what is out is a gift to the team and to your budget, and it is the single strongest defense against a project that never ships.
If you cannot write done statements yet, say so in the brief. Honest uncertainty reads far better than confident vagueness, and a good team will help you sharpen it.
A brief template you can copy
One to two pages is enough. Bullet points beat prose. Structure it like this:
- The problem. Three sentences, zero solutions.
- Who lives with it. Roles, rough headcount, how often the pain hits.
- The current workaround. Attach the spreadsheet, forms, screenshots, or a screen recording.
- User stories. Five to ten "when, who, needs, otherwise" lines, ranked by importance.
- Done. Three to five checkable statements.
- Not now. What the first version deliberately excludes.
- Constraints. A hard deadline if one truly exists, a budget range, and any systems the software must talk to.
- Open questions. The things you genuinely do not know yet.
Send it as a document the team can comment on, not a PDF frozen in place. The brief is the start of a conversation, not the end of one.
Mistakes that quietly sink a brief
- Prescribing the stack. Naming a technology because you read about it constrains the team without helping them. Mention technology only when it is a real constraint, such as an existing system the new software must integrate with.
- Hiding the budget. A range changes what comes back. Without one, teams guess, and the guess is usually padded to cover the unknown.
- Polishing away the mess. The ugly parts of your process are precisely the parts worth automating. A sanitized brief produces software for a company that does not exist.
- Writing for a committee. A document crafted to survive internal approval reads very differently from one written to get software built. Write the honest version first.
A good team will respond to a brief like this with questions rather than an instant quote, and that is a healthy sign. If you have a draft and want a second pair of eyes on it, you can reach us here.
Frequently asked questions
How long should a brief for software developers be?
One to two pages of core content, plus attachments. Length is not the goal, checkability is. A short brief with a ranked list of user stories, clear done statements, and the real spreadsheet attached beats a twenty-page requirements document that nobody, including its author, fully reads.
Should I suggest technologies if I am not technical?
Only when they are genuine constraints, such as a payment provider you already use or a system the new software must integrate with. Otherwise, leave technology choices to the team. Naming tools you have read about narrows their options without adding information, and it can steer the estimate in the wrong direction.
Should I include my budget in a software development brief?
Yes, as a range. A budget range lets the team shape a proposal that fits, and it surfaces mismatches early instead of after weeks of discussion. Hiding it does not create leverage. It creates guessing, and guesses from a cautious vendor tend to come back higher, not lower.
What if I cannot define what done looks like yet?
Say so directly in the brief and list your open questions. A capable team will treat that as the first piece of work, helping you turn vague goals into checkable statements before committing to a build. Pretending certainty you do not have is what leads to rework and blown timelines later.
