Getting three proposals for a software project and choosing the middle one by price is not evaluation. It's pattern-matching on incomplete information.
Price is one variable. Scope, timeline, technology choices, IP terms, and post-launch support are others — and they matter as much as price, sometimes more. Two proposals at very different prices are often describing completely different scopes. Comparing them on price alone is like comparing two construction quotes where one includes the foundation and one doesn't.
Here's what to actually look at.
Scope Clarity
A good proposal describes in specific terms what is and is not included. Not "we will build you an inventory management system" but:
- Which modules: stock tracking, reorder alerts, supplier management, purchase orders?
- Which user roles and permission levels?
- Which integrations: accounting software, e-commerce platform, logistics API?
- Which platforms: web only, mobile, both?
- What data migrations from existing systems?
- What training and documentation?
A proposal that describes the project in broad, vague terms is not a proposal — it's a placeholder for a later negotiation you're going to lose. Vague scope means disputes later. "That wasn't included" is the most common sentence in a troubled software project, and it almost always traces back to a scope that was never clearly defined.
If a proposal doesn't answer these questions, send it back with specific questions before you compare it to anything else.
Timeline Realism
Is the proposed timeline realistic for the scope described?
Experienced developers know how long similar projects take. A fully custom ERP system does not get built in six weeks. A mobile app with a backend, multiple integrations, and App Store submission does not take four weeks from kickoff to launch. If a proposal quotes a timeline that seems implausibly short for the scope described, it means one of three things: the scope is narrower than you think, they're planning to use shortcuts that will cost you later, or they're telling you what you want to hear.
Ask how they arrived at the timeline. A good vendor can walk you through the phases and explain the reasoning. A vendor who can't explain the timeline hasn't thought it through.
Technology Choices
Does the vendor explain what they're building with and why?
You don't need to understand every technical decision, but you should expect the vendor to be able to explain the main choices in plain language: what language or framework, what database, what hosting environment, why these choices for your specific use case.
This matters for your long-term interests. If the vendor builds your system in an obscure language that only they know, you have a dependency that puts you at their mercy forever. If they build in mainstream, widely-used technology, you can find other developers to maintain it if the relationship ends.
Ask: "If our relationship ended after this project, how hard would it be to find another developer to maintain this codebase?" A good vendor will give you an honest answer.
IP and Code Ownership
Who owns the code after the project is done?
This sounds obvious — you're paying for it, you own it — but this is not legally guaranteed without explicit contract language. In many jurisdictions, a contractor who writes code retains copyright unless they explicitly assign it in writing. A contract that says "we will build you a system" without clear IP assignment language may leave the code owned by the developer.
The proposal and subsequent contract should state explicitly:
- Full source code is delivered to you at project completion
- All intellectual property created during the project is assigned to you
- The developer does not retain a license to reuse your code in other projects
If a vendor resists putting this in writing, that's a red flag serious enough to disqualify them.
Post-Launch Support
What happens the day after launch?
A project that goes live on a Friday and has a critical bug discovered on Monday needs support. Who handles this? Is it covered by the project fee? Is there a warranty period? What's the response time commitment?
Good proposals address this explicitly:
- A defined warranty period (typically 30-90 days) covering bugs in the delivered scope
- Clarity on what's a bug (costs nothing extra) vs. what's a change request (additional cost)
- An option for an ongoing maintenance retainer if you want continued support
- Contact channels and response time expectations
A vendor who delivers and disappears is not a partner — they're a one-time transaction with no accountability after handover.
Payment Terms
Are payment milestones tied to deliverables?
A project with milestone-based payments — 30% at kickoff, 30% at design approval, 30% at development completion, 10% at go-live — aligns incentives. The vendor gets paid as they deliver. You have leverage to withhold payment if deliverables aren't met.
A vendor who asks for 80% upfront is transferring risk to you entirely. You're hoping they deliver. They have little financial incentive to prioritize your project once most of the payment is received.
Milestone payments are standard practice. A vendor who doesn't offer them should be able to explain why.
Price — and Why It's the Last Thing to Compare
Price is a factor. It's not the primary factor.
A proposal with a clear scope, realistic timeline, good technology choices, explicit IP terms, and milestone-based payments at a higher price is almost always a better deal than a vague, cheap proposal that delivers ambiguously. If you want to understand what a realistic cost looks like before you start comparing proposals, the real cost of custom software development provides a useful baseline for both upfront and ongoing costs.
The cheapest proposals consistently have the vaguest scopes — because unclear scope lets the vendor cut corners on whatever they didn't explicitly promise to include. The dispute always arrives later, and it's expensive.
Compare scope. Compare terms. Compare timeline logic. Then compare price. In that order.
CERIS provides detailed proposals that describe scope explicitly and can be compared line by line against any alternative. See our web development service or get in touch and we'll give you something worth comparing.
