You have described your idea to a software development company, waited a few days, and now a proposal has landed in your inbox. It is several pages long, contains diagrams you do not fully understand, and ends with a number that is either reassuring or alarming depending on what you expected.
The question now is: how do you know if this is a good proposal?
Most business owners evaluate proposals on price and gut feeling. Both matter, but they are not enough on their own. A proposal can look expensive and be good value. It can look reassuringly cheap and turn out to be a disaster. The difference is usually in the details — and knowing which details to look for makes the difference between a project that delivers and one that does not.
What a good proposal actually contains
Before evaluating any specific element, it is useful to know what a serious proposal should include. A well-written proposal from a competent development company will typically contain:
- A clear description of the problem being solved
- A defined scope of work (what is included, and importantly, what is not)
- A project timeline with phases or milestones
- A cost estimate broken down by component or phase
- A description of the development process and how they will communicate with you
- Information about the team that will work on the project
- Terms and conditions, including what happens if scope changes
If a proposal is missing several of these elements, that is a signal worth paying attention to. Vague proposals often lead to vague deliverables.
Start with how well they understood your problem
The most important thing to read in any proposal is how the company describes your problem. Before they describe their solution, do they demonstrate that they understood what you were trying to achieve?
A strong proposal will restate your business challenge in their own words. It will identify the people who will use the software and what they are trying to accomplish. It may highlight challenges or risks they noticed that you did not mention.
A weak proposal jumps straight to the solution. It describes features and technologies without showing any deep understanding of why those features matter to your specific situation.
If a company's proposal could have been written for any business in your industry without changing a word, it was almost certainly written that way. A proposal that reflects genuine understanding of your situation will always contain things that are specific to you.
Evaluate the scope section carefully
Scope is where most software projects go wrong, and it is where most disputes between clients and developers originate.
Read the scope section carefully and ask yourself two questions.
First: does this scope actually cover what I need? It is surprisingly common for proposals to describe something that sounds like what you asked for, but which subtly does not include key functionality. If you need the system to integrate with your existing accounting software, for example, make sure that integration is explicitly named in the scope — not implied by a vague reference to "external system connections."
Second: what is explicitly excluded? Good proposals are clear about what they are not doing. If a company promises a web application but the proposal does not mention mobile devices, you should ask directly whether the application will work on phones and tablets, and what the answer means for the price.
Things left ambiguous in a proposal tend to become disputes later. The time to resolve ambiguity is before signing.
Understand how the price is structured
Price is usually the first thing a business owner looks at and sometimes the last thing they understand. A single number at the bottom of a proposal tells you very little. How that number is broken down tells you a great deal.
Look for a breakdown that shows:
- How much time is allocated to each phase of work
- Which team members will work on which parts, and at what rates
- What is fixed price versus what is estimated
Fixed-price proposals give you certainty but less flexibility. If your requirements are clear and unlikely to change, this is often a good structure. If your requirements will evolve as you learn more, a fixed price can work against you — because adding to the scope will require formal change requests and additional cost negotiations for every adjustment.
Time-and-materials proposals give you flexibility but less cost certainty. Your final bill will depend on how the project develops. This is appropriate for complex or exploratory projects, but it requires you to actively manage scope and budget as work progresses.
Most proposals fall somewhere in between: a fixed price for a well-defined initial phase, with flexibility built into later phases. This is often the most sensible structure for custom software, but make sure you understand how the boundaries are drawn.
Look at the timeline and ask what can go wrong
A credible timeline includes milestones, not just a start date and an end date.
Milestones tell you when specific parts of the work will be complete, which gives you checkpoints to evaluate progress and makes it easier to spot problems early. A timeline that is simply "six months from contract signing" with nothing in between offers you very little visibility into what is actually happening during those six months.
When reading the timeline, ask: what assumptions is this based on? Most timeline estimates depend on things outside the developer's control — how quickly you can provide feedback, how long it takes to get access to existing systems, whether third-party services respond to integration requests in a timely way.
A good proposal will name these dependencies explicitly. A proposal that presents a timeline as unconditional, with no mention of what could cause delays, either has not thought carefully about the project or is understating the risks.
Assess how they plan to communicate with you
For business owners without a technical background, communication is not just a nice-to-have — it is the primary way you will understand what is being built and whether it is on track.
Look in the proposal for specific answers to these questions:
- How often will you receive status updates, and in what format?
- Who is your point of contact, and how available are they?
- How are decisions made during the project, and who needs to approve them?
- How are problems reported and escalated?
If the proposal is silent on communication, raise it directly. The answer will tell you a lot about how the company actually operates. Teams that have good communication practices will have ready answers. Teams that have not thought about it will be vague.
Check how they handle changes
Scope changes are not a sign that a project is going wrong. They are a normal part of building software for a real business, because no one knows everything they need at the start. What matters is how changes are handled.
Look for a clear change management process in the proposal. When you ask for something that was not in the original scope, what happens? Is there a formal process for estimating and approving the additional cost? Is there a buffer built into the estimate for minor adjustments? What counts as a change versus a bug fix?
Companies with good change management processes will describe this clearly. Companies that have not thought about it often paper over it with language like "we will be flexible," which is not actually a process.
Ask about what happens after delivery
The proposal should address what happens when the project is done. This includes:
- Who owns the source code, and what are your rights to it?
- What happens if bugs are discovered after launch?
- Is there a warranty period, and what does it cover?
- What does ongoing maintenance and support look like, and what does it cost?
These questions are often not asked until they become urgent, at which point the answers are less negotiable. Raising them during the proposal evaluation stage is the right time.
Compare proposals on substance, not just price
If you have received proposals from multiple companies, resist the temptation to simply rank them by price and choose the cheapest.
Instead, compare them on these dimensions:
- How well did each company understand your problem?
- How clear is the scope, and how specifically does it address your needs?
- How detailed and realistic does the timeline appear?
- How transparent is the cost breakdown?
- How confident are you in their communication approach?
A more expensive proposal that answers these questions well is almost always a better investment than a cheaper one that leaves them open. The true cost of a software project is not the initial estimate — it is the final amount you pay to get something that works. Projects that start cheaply and go wrong consistently end up costing more than well-planned projects that started with a higher initial estimate.
When to ask for clarification before deciding
If anything in a proposal is unclear, ask about it before signing. This is not an imposition — it is a reasonable expectation, and a company that resists clarifying their proposal before you commit is giving you useful information about how they will behave later.
Questions worth asking if they are not addressed in the proposal:
- Who specifically will work on this project?
- Have you built something similar before? Can I speak with that client?
- What is the biggest risk in this project, and how are you planning to manage it?
- What would cause this project to go over budget or over time, and what is your plan if that happens?
The quality of the answers to these questions tells you as much about a company as the proposal itself.
Evaluating proposals is a skill that improves with experience, but even on your first project, careful reading and a few direct questions will take you a long way.
