How to write a software project brief that gets accurate quotes
What a good software brief contains, what to leave out, and a copy-ready template that gets you comparable, fixed-price quotes.
On this page
A good software brief fits on one or two pages and answers seven questions: what problem you are solving, who has it, what exists today, what the first release must do, what constrains you, how you will judge success, and how you will choose a supplier. Send the same brief to every supplier and their quotes become comparable. Below is what to include, what to leave out, and a template you can copy.
Why quotes for the same project differ so much
Ask five software companies to quote for "an app like Uber, but for tutors" and you will get five prices that differ by a factor of ten. That is not because some are honest and some are not. Each supplier is filling the gaps in your request with its own guesses: how many users, which platforms, which payments, how polished, how soon.
A brief removes the guessing. It does not need technical language or a full specification. It needs the facts about your business that only you know.
The seven parts of a good brief
1. The problem
Describe the problem in two or three sentences, and who has it. Say what it costs today, in time, money or lost customers. "Our receptionists spend three hours a day booking appointments by phone, and we lose bookings after hours" is far more useful than "we need a booking app".
2. The users
Who will use the software, and roughly how many? Customers, staff, administrators? On phones, laptops or both? In which languages? Ten internal users and fifty thousand members of the public are different projects.
3. What exists today
List the tools, data and assets you already have: a website, a spreadsheet, an existing app, a payment provider, brand guidelines, a domain. Say what must connect to what. Integrations are often the largest hidden cost in a project.
4. The first release
Separate the must-haves for a first release from the nice-to-haves for later. Be ruthless: the first release exists to prove the idea works with real users. A short, prioritised list is worth more than a long feature wish-list.
5. Constraints
- Deadline, and what makes it a deadline: an event, a season, a funding milestone.
- Budget range. Even a rough range lets suppliers propose the right-sized solution instead of guessing.
- Technical constraints, such as a language your team already uses, or a platform you must stay on.
- Compliance, such as data protection rules, payment processor requirements, or industry regulations.
6. How you will measure success
What will be different three months after launch? Fewer phone bookings, a conversion rate, hours saved, revenue? Success measures help a supplier make sensible trade-offs on your behalf.
7. How you will decide
Tell suppliers your timeline for choosing, what you will compare, and who decides. It saves everyone time and signals that you are a serious buyer.
What to leave out
- Detailed screen designs, unless you already have them. Describe what users need to do, and let the supplier propose how.
- Technology choices you do not need to make. "It must be built in React" constrains the supplier for no benefit unless your team will maintain it.
- Comparisons without detail. "Like Uber" tells a supplier about the look, not about the scope. Name the specific features you mean.
- Confidential material before an NDA. A good brief explains the problem without revealing anything sensitive. Share details once a mutual NDA is signed.
Common mistakes
- Describing a solution instead of a problem. "We need a mobile app" closes doors that "customers cannot book after hours" leaves open. Sometimes the best answer is a web page, not an app.
- Treating every feature as essential. If everything is a must-have, nothing is, and the first release takes three times as long. Rank your list.
- Hiding the deadline's reason. "By March" is a constraint; "before the March trade fair, where we will demo it" lets a supplier plan the right first release.
- Sending different briefs to different suppliers. Small differences in what you ask produce large differences in what you are quoted. Send everyone the same document.
- Forgetting who maintains it. Say who will run the software after launch, your team or the supplier, because it changes how it should be built and documented.
Why sharing a budget range helps you
Many buyers hide their budget, hoping for a lower quote. In practice the opposite happens: suppliers either quote for an over-built solution to protect themselves, or a cheap one that will not do the job. A range lets a good supplier tell you what is realistic for that money, and what to cut or phase. You stay in control because you choose the scope.
How to compare the quotes you get
When the quotes come back, compare more than the total:
| Question | Why it matters |
|---|---|
| Is it a fixed price, or time and materials? | A fixed price moves the risk of overruns to the supplier, for a defined scope |
| What exactly is included? | Testing, deployment, documentation and post-launch fixes are often left out |
| What assumptions are listed? | Assumptions are where surprise costs hide |
| How are payments tied to milestones? | You should pay for delivered, working software, not for time passed |
| Who owns the code, and where does it live? | It should be in your repository, assigned to you on payment |
| Who will actually do the work? | Meet the engineer, not just the salesperson |

Contact: name, email, time zone
An example
Here is a short, invented example of a brief that would get accurate quotes:
Problem: A three-branch dental clinic books every appointment by phone. Receptionists spend about three hours a day on calls, and after-hours callers book elsewhere.
Users: Around 400 patients a month booking on their phones, in English and Urdu; six receptionists managing the calendar.
Today: A WordPress website, a shared Google Calendar per branch, and SMS reminders sent by hand.
First release: Online booking by branch, dentist and treatment; SMS confirmation and a reminder the day before; a simple calendar view for reception. Later: online payment of deposits.
Constraints: Live within ten weeks, before the winter rush. Budget range US$4,000 to 7,000. Patient data must stay private.
Success: Half of all bookings made online within three months.
That is about 150 words, and any competent supplier can quote against it with confidence.
