If you're evaluating software development vendors, an RFI is where the process actually starts. This guide breaks down what to ask, what a strong response looks like, and gives you a ready-to-use template so you're not writing one from scratch.
✓Key Takeaways
Quick answer: An RFI for software development is a short document, usually two to four pages, sent to potential vendors before you've locked in scope or budget, used to filter a long vendor list down to a shortlist worth taking to a full RFP. A strong one asks specifically about team structure, IP ownership, and security certifications, not just company background, and states a real budget range so responses are actually comparable. Most RFIs fail the same way: they ask for RFP-level detail too early, which gets you either no response or a rushed, generic one.
What Is an RFI in Software Development?
A software development RFI is a document a company sends to potential vendors to learn who they are, what they've built before, and whether they're worth talking to further. It usually runs two to four pages: a short description of your project and goals, followed by a set of questions about the vendor's experience, team, and process.
One thing worth clearing up: if you search "RFI software," you'll get a mix of results. In construction and engineering, "RFI" refers to a question raised during a project (usually inside project management tools like Procore), which is a completely different use of the term. This guide is about the procurement document, the one you send before choosing a software development partner.
RFI vs. RFP vs. RFQ
These three get used interchangeably, which causes real confusion when you're actually running a vendor search. Here's the difference, based on how APMP defines each solicitation type:
| RFI | RFP | RFQ | |
|---|---|---|---|
| When you use it | First, to narrow a long list | After you've shortlisted vendors | When scope is fixed and you just need pricing |
| What you're asking for | General capability and fit | A detailed proposal: approach, team, timeline, cost | A specific price for a specific scope |
| How defined your project needs to be | Loosely defined is fine | Should be fairly well defined | Fully defined |
In short: RFI answers "who should we even be talking to," RFP answers "how would you do this and what would it cost," and RFQ answers "what's your price for exactly this."
Why Send an RFI Before an RFP
Skipping straight to an RFP feels faster, but it usually isn't. Writing a full RFP takes real effort, and reviewing five or ten full proposals takes even more. An RFI lets you screen out vendors who clearly aren't a fit (wrong industry experience, wrong team size, wrong engagement model) before anyone invests that time.
It's also useful when your requirements aren't fully locked yet. An RFI doesn't commit you to a scope, so you can ask open questions like "how would you typically approach a project like this" and use the answers to sharpen your own thinking before you write the RFP.
The 10 Things a Strong Software Development RFI Should Ask
A generic RFI gets generic answers. These ten go deeper than the usual checklist, with what a strong answer sounds like versus a red flag, so you actually know what to do with the response you get back.
1. Company background
Company age tells you less than team stability. A vendor that's been around ten years but rotates 40% of its delivery staff every year is a different risk than one that's three years old with a core team that hasn't turned over. Ask directly how long the engineers you'd actually work with have been at the company, not just how long the company has existed.
2. Relevant project examples
Don't just ask for examples, ask what went wrong on one of them and how it got handled. A vendor that only offers success stories is filtering for you; one willing to walk through a real setback and the fix is showing you how they behave when something breaks on your project too. Also worth asking: did they build this from scratch, or inherit and maintain someone else's code? Those are very different skill sets.
3. Technical stack and approach
Watch for vendors who recommend the same stack regardless of what you describe. That's usually a sign they're fitting your project into their comfort zone rather than actually evaluating it. A stronger answer explains a trade-off: for example, why they'd skip microservices for a team your size, even though it's trendy, because the operational overhead isn't worth it yet. If every answer is just a list of technology names with no reasoning attached, push for the reasoning.
4. Team structure
This is the single highest-signal question on the list. "Dedicated team" gets used loosely, so ask directly whether the same engineers are staffed on other clients at the same time, and what happens if someone leaves mid-project: is there a replacement guarantee, and how long does ramp-up take for whoever backfills. Vendors running a shared-resource model can often quote a faster start date, because they're already spread thin across several clients. That speed isn't free. It tends to show up later as slower response time when you actually need something.
5. Quality assurance process
"We test thoroughly" means nothing. Ask for the QA-to-developer ratio, whether QA sits inside the sprint or happens as a separate downstream phase, and what percentage of the test suite is automated. A vendor that can't give you a number probably isn't measuring it, and that absence is itself useful information.
6. Security, confidentiality, and IP ownership
Ask for specific certifications (ISO/IEC 27001, SOC 2) instead of accepting "we follow best practices." Just as important: ask exactly when IP transfers to you, at contract signing, at final payment, or per completed sprint. Most IP disputes happen at exactly that boundary, when a client assumes a deliverable was already theirs and the vendor considers it unpaid and therefore unreleased. This is the question buyers skip most often because it feels like boilerplate, right up until it isn't.
7. Communication and reporting
The real question underneath this one is whether you're getting direct access to engineers or a relay layer, an account manager who passes messages back and forth. Ask specifically who you'd be messaging day to day, and ask to see a sample weekly report if they have one. If the answer is vague about who you'd actually be talking to, assume there's a layer between you and the people doing the work.
8. Timeline and onboarding speed
Ask for a range and what it depends on, not a single number. A vendor who promises an unusually fast start, "next week, guaranteed," for a specialized stack is often telling you they'll staff whoever happens to be free, not whoever's actually the right fit. Availability and fit are two different things, and a confident-sounding fast timeline can be a sign they've optimized for the wrong one.
9. Pricing model and engagement options
Instead of just asking for a rate card, ask them to walk through which engagement model (dedicated team, project-based, staff augmentation) they'd actually recommend for your situation and why. A vendor that defaults to recommending their highest-margin model regardless of what you described, for example pushing a dedicated team onto a tightly scoped two-month MVP, is optimizing for their revenue, not your fit.
10. References
Ask for a reference from a project that's wrapped up or a client relationship that ended, not only active, happy clients. Former or completed-project clients tend to give more candid answers about what the day-to-day engagement actually felt like, since they're not worried about the relationship going forward.
Common Mistakes When Writing a Software RFI
Writing an RFP by accident
This usually looks like a "simple" RFI with forty detailed technical questions and a request for a fixed quote. Vendors respond to that in one of two ways: they decline, because it's unpaid RFP-level work with no guarantee of winning anything, or they rush a shallow answer just to stay in the running. Either way, you lose the signal an RFI is supposed to give you. Keep it exploratory and save the detailed scope for the RFP.
Leaving out a budget range
Without one, vendors either quietly self-select out, assuming they're the wrong price tier and never responding, or a vendor who's a poor fit but hungry for the work responds enthusiastically because any number looks fundable when you don't have one to compare against. You don't need precision. "$150K to $300K" or "flexible depending on approach" is enough to filter correctly.
Skipping IP and security questions
Most buyers assume this is standard boilerplate that gets sorted out at contract signing, and only find out otherwise mid-dispute, usually when they discover source code access wasn't included in what they'd already paid for. Ask before you're emotionally invested in a specific vendor, not after.
Sending it to too many vendors at once
Ten RFIs sent out means ten reviewers who can tell, consciously or not, that they're one of ten. Response quality tends to track how seriously a vendor thinks they're being considered, so a mass blast usually comes back as ten templated marketing responses. A shortlist of four to six, chosen with some actual filtering first, gets you real answers.
Asking open-ended questions
"Tell us about your QA process" gets you a paragraph of marketing language. "What percentage of your test suite is automated, and how do you handle regression testing when priorities shift mid-sprint" gets you an actual answer you can compare against the next vendor's actual answer. The difference is almost always in how specific the question is, not how long the RFI is.
What a Strong RFI Response Looks Like
A weak response restates your questions back at you in generic terms. A strong one gives you something concrete to check.
Look for responses that:
- Name real, verifiable credentials (certifications, ratings on third-party platforms like Clutch) instead of vague claims like "highly rated."
- Describe a specific past project close to yours, including what went wrong and how it was handled, not just the highlights.
- Explain exactly who would be on your team and whether that team works only for you.
- Answer the security and IP questions directly, without redirecting to "we'll cover that in the contract."
As an example of what that level of detail looks like in practice: in InApps' Two Raw Sisters case study, the engagement is documented with the specifics a buyer would actually want to see: what the starting problem was, what changed, and by how much (6,000+ active subscribers on the platform, and a 3x increase in feature delivery speed after the team took over). That's the level of specificity worth holding every RFI response to, regardless of which vendor you're evaluating.

How to Evaluate the Responses You Get Back
Once responses are in, score them against a short list rather than reading each one in isolation:
- Specificity. Did they answer your actual questions, or send a generic capabilities deck?
- Fit. Does their team size and experience match your project, not just their biggest logos?
- Transparency. Did they answer the IP and security questions directly?
- Consistency. Do their claims (ratings, certifications, client counts) check out against public sources like Clutch or their own case studies?
Vendors who score well across all four are the ones worth moving to an RFP. If two or three vendors are close, that's a normal outcome, the RFP stage is where the real differences usually show up.
