A software vendor's quote is only as good as the information behind it. If your needs are passed on in a quick chat or a single WhatsApp message, each vendor fills the gaps with its own assumptions. The result is quotes that are hard to compare and a project that changes direction halfway through. A well-prepared software project brief prevents most of these problems.
A brief does not need to be a technical document. It explains your business, the problem you want to solve, and the constraints a vendor needs to know about. This article covers what belongs in it, with an outline you can use right away.
What a brief does for a software project
A brief has three uses. It helps your own team agree on what is actually needed before any vendor is involved. It makes every vendor read the same requirements, so quotes can be compared fairly. It also becomes the starting point for discovery, so meeting time goes into detail instead of explaining the basics of your business.
A good brief is usually a few pages long. Being clear and honest matters more than length.
Who writes it matters too. One person who understands daily operations, such as an operations manager or head admin, is usually enough. The draft is then read by the owner and one or two future users. This often brings internal disagreements to the surface, and it is better for them to appear now than after the vendor has started work.
What goes into a software project brief
Business goals
Start with why the project exists. Describe the problem you want to solve and what success looks like. For example, a cleaning services company that no longer wants to recap staff schedules and visit reports by hand from a WhatsApp group at the end of every week. A goal like this helps the vendor prioritise features.
Users and their roles
List who will use the app and what they do. Office admins, field staff, supervisors, customers, and owners all have different needs. Give rough numbers, and note the devices they use, such as Android phones in the field and laptops in the office.
Current processes
Walk through today's workflow step by step, including the parts that still run on paper, spreadsheets, or chat. At a notary office, for instance, the flow might start with a client handing over documents, staff checking that everything is complete, and end with the deed finished and archived. Attach sample forms and reports. This section is often the most useful material a vendor receives.
Must-have and nice-to-have
Not every wish needs to be in the first version. Split your requirements into two groups. Must-haves are the things without which the app cannot be used for core work. Nice-to-haves are useful, but work can carry on without them for a while.
For an event organiser, participant registration and on-site check-in might be must-haves, while analytics reports and an accounting integration can come later. This split helps the vendor plan stages and helps you control the budget. If everything is marked as a must-have, the vendor has no basis for suggesting a leaner first version.
Integrations, data, and constraints
List the systems already in use that need to connect, such as accounting software, a payment gateway, marketplaces, or WhatsApp. If you know, say whether those systems have an API. This has a big effect on the amount of work.
Describe your current data as well. Where it is stored, roughly how much there is, and whether it needs to move to the new system. If the app will store personal data about customers, patients, or employees, say so clearly. Indonesia's Personal Data Protection Law (UU PDP, Law No. 27 of 2022) makes it important to discuss these security needs from the start.
Finally, write down the constraints a vendor should know. A budget range, a target date tied to a specific event such as a branch opening, internal policies on data storage, or a requirement to use a particular cloud provider. Sharing a budget range helps vendors propose a realistic scope.
A brief outline you can use
Here is a simple outline you can copy and fill in:
- Company background, covering your line of business, number of branches or teams, and how you work in general.
- The problem to solve and how you will know it is solved.
- Users, their roles, rough numbers, and the devices they use.
- Current workflow, with sample forms, reports, or screenshots attached.
- Must-have requirements for the first version.
- Nice-to-have requirements for later.
- Systems that must connect, with API details if available.
- Existing data, migration plans, and the types of personal data to be stored.
- Constraints such as budget range, target dates, and internal policies.
- A contact person on your side who can make decisions.
Not every section has to be complete. Writing "not sure yet" in a section is still better than leaving it blank, because it tells the vendor the point needs discussing.
What to do once the brief is ready
A finished brief can go straight to several vendors, or you can first review it with an independent party to check whether the plan makes sense. Averoa offers architecture reviews, build vs buy analysis, and technology roadmaps before budget is committed. You can read more on the Technology Consulting page.
