Software project requirements checklist
Ambiguity is the most expensive item in any software quote. Vendors price risk — so the clearer your brief, the more accurate and comparable the numbers you get back.
Before requesting quotes, document six things: who will use the system and in what roles, the workflows they need to complete, what data is involved and where it currently lives, which systems must integrate, what reporting is required, and how you will judge success. You do not need technical detail — you need clarity about the business problem.
You are not expected to write a technical specification. That is the vendor's job. What only you can supply is an accurate description of how your organisation actually works, including the awkward exceptions everyone has learned to handle informally.

1. The problem
- What is going wrong today, in concrete terms?
- How much time or money does it cost, roughly?
- What have you already tried?
- What happens if you do nothing?
2. Users and roles
- Who will use this — staff, customers, partners, members?
- How many of each, today and in three years?
- What distinct roles exist, and what should each be able to see and do?
- Who administers the system day to day?
- Will anyone use it on a phone, in the field, or with poor connectivity?
3. Workflows
For each main process, describe it as a sequence: who starts it, what information they provide, who acts next, what decisions get made, and how it ends. Then — importantly — describe the exceptions:
- What happens if the approver is unavailable?
- Can something be cancelled or reversed, and by whom?
- What if information arrives incomplete?
- Are there deadlines, escalations or reminders?
Exceptions are where most of the build cost and most of the disagreements live. Surfacing them early is the highest-value thing in this checklist.
4. Data
- What information does the system store?
- Where does it live now — spreadsheets, another system, paper?
- Does historical data need migrating, and how far back?
- How clean is it, honestly?
- Is any of it personal, financial or otherwise sensitive?
- Who is allowed to see, export or delete it?
5. Integrations
- Which systems must this connect to?
- In which direction does data flow, and how current must it be?
- Do those systems have APIs, and who supports them?
- Who is your contact for each one?
6. Reporting
- What questions must the system answer?
- Who needs which report, and how often?
- Does anything need exporting to Excel or another system?
7. Constraints
- Is there a deadline, and what drives it?
- What is your realistic budget range?
- Any technical or hosting requirements from your IT policy?
- Any regulatory or audit obligations?
8. Success criteria
Write down how you will judge whether this worked, in terms a non-technical colleague would accept — hours saved per week, errors eliminated, faster turnaround, fewer phone calls. Vague goals produce vague systems.
9. Separate must-have from nice-to-have
Split every requirement into essential for launch, important but can follow, and ideas for later. This single act is the most reliable way to control cost, and it lets a vendor propose a sensible phase one instead of quoting for everything.
10. What you do not need to specify
Leave the technology to the vendor — programming languages, frameworks, database choice and hosting architecture. Specifying these without a technical reason narrows your options and can raise the price. State the outcome and the constraints; let the engineers choose the tools.
Using this to get comparable quotes
Send the same document to every vendor. Ask each to state their assumptions and exclusions explicitly. When quotes differ substantially, the reason is almost always a differing interpretation of scope — which this document is designed to eliminate.
When you are ready, send us your requirements. If you would rather talk it through first, that is often faster — book a consultation and we will help you fill the gaps.
Frequently asked
Detailed about the business problem, not the technology. A few clear pages describing users, workflows, exceptions and success criteria is far more useful than a long document full of technical guesses.
That is normal and worth saying explicitly. Marking something as undecided is far better than leaving it out — a vendor can then flag it as an assumption or an area to resolve during discovery rather than silently pricing around it.
Yes, at least as a range. It is not an invitation to spend it all — it lets a vendor propose a scope that fits, or tell you early that your expectations and budget do not match, which saves everyone time.
No, unless your IT policy requires it. Specifying languages or frameworks without a technical reason narrows your options and can increase cost. Describe the outcome and constraints and let the vendor recommend an approach.
