Writing a Request for Proposal (RFP) for App Development

Short answer

A request for proposal, or RFP, is a formal document you send to app development companies to solicit competitive proposals. It suits larger or enterprise projects that need a structured, fair comparison. It should describe the problem, users, requirements, budget range, timeline, and evaluation criteria, focusing on what the app must do, not how to build it. For many smaller projects, a clear brief and a real conversation work better than a rigid RFP. For the lighter version, see our guide on how to pitch an app idea to developers.

What an app development RFP is

An RFP is a structured way to ask several companies to propose how they would build your app, on the same terms, so you can compare them fairly. Instead of an informal chat with one developer, you write a document describing what you need and send it to a shortlist of vendors, each of whom responds with a proposal covering their approach, plan, team, and price. It is, in essence, the procurement world’s tool for making a considered, comparable choice among competing options.

That structure is its strength and its cost. The strength is fairness and comparability: because every vendor answers the same questions, you can line up their responses and judge them side by side, which matters when the project is large or when an organization requires a documented, defensible process. The cost is formality: an RFP takes real effort to write and to respond to, and its one-way, document-driven nature can discourage the back-and-forth conversation that produces the best thinking. Understanding both sides is the key to using an RFP well, because it is the right tool for some situations and overkill for others.

Do you actually need an RFP?

Before writing one, it is worth asking honestly whether an RFP fits your situation, because for many projects it does not. An RFP earns its formality when the project is large, when you genuinely need to compare several vendors on equal terms, or when you work in an organization, public sector, enterprise, that requires a formal procurement process. In those cases, the structure is valuable and often mandatory.

For a smaller project or a first-time founder, though, a full RFP is often the wrong tool. Writing and running one takes time and effort, and its rigid, one-way format tends to produce cautious, boilerplate responses rather than the genuine collaboration you want. A clear brief and a few real conversations with promising partners usually get you further, faster, because they let a good partner ask sharp questions, suggest what to cut, and show how they think, none of which a stiff RFP invites. So the first decision is not what to put in your RFP, but whether an RFP is the right approach at all, or whether a lighter, more conversational path serves you better.

What to include in an app development RFP

Section	What it covers
Problem and goals	Why you are building the app and what success looks like
Users	Who the app is for and how they will use it
Requirements	Must-have features versus nice-to-haves
Budget range	A realistic band, so proposals are grounded
Timeline	When you need it and any key dates
Evaluation criteria	How you will judge and compare proposals
Submission details	Format, deadline, and how to respond

A good RFP gives vendors what they need to respond well and gives you comparable answers. The most important parts are the problem and goals, so vendors understand what you are really trying to achieve, and the requirements split into must-haves and nice-to-haves, so they can scope sensibly. Including a budget range is worth doing despite the temptation to hide it, because it lets vendors propose something realistic rather than guess, and stating your evaluation criteria up front signals fairness and helps vendors put their best foot forward. A structured RFP like this also marks you as a serious, organized buyer, which good companies respond to.

One line item belongs in every app RFP regardless of size: require that the app ships under your own Apple Developer account and that you own the code. The Apple Developer Program costs 99 US dollars per year as of 2026, the same rate for individuals and organizations, so there is no financial reason for a vendor to publish your app under theirs. A vendor who resists that clause is telling you something useful before the project even starts.

Describe the what, not the how

A common mistake in app RFPs is over-specifying the technology, dictating that the app must be built a certain way, with a particular stack, before any vendor has weighed in. This usually backfires, because how to build the app, natively in Swift for iOS, what the backend looks like, which services to use, is the vendors’ expertise and part of what you are evaluating.

When an RFP prescribes the how, it can lock every vendor into an approach that may not be best, and it hides exactly the thinking you should be comparing: how each vendor would solve your problem. The stronger approach is to describe the what and the why in detail, the problem, the users, the outcomes, the requirements, and let each vendor propose the how, then judge those proposals partly on the quality of that technical thinking. Following Apple’s Human Interface Guidelines and getting the app through Apple’s App Store Review Guidelines are outcomes to expect, not implementation details for you to dictate. Keep the RFP focused on your needs, and let the responses reveal how each vendor thinks.

How to evaluate the responses

What to weigh	Why it matters
Relevant shipped work	Proof they can actually deliver
Understanding of your problem	Did they grasp what you need, or just quote?
Clarity and realism of the plan	A vague or too-good plan is a warning
Budget and what it includes	Compare scope, not just the bottom line
Ownership terms	Do you own the code and account?
Communication	How they respond predicts the project

The point of an RFP is a fair comparison, so evaluate the responses on consistent criteria rather than on price alone. The strongest signals are relevant apps the vendor has actually shipped and can show you, and how well each proposal demonstrates that the vendor understood your specific problem rather than pasting a generic pitch. Weigh the clarity and realism of the plan, what the budget actually includes, and the ownership terms, and pay attention to how each vendor communicated during the process, because that predicts the working relationship. A structured RFP makes this comparison possible, but the judgment is still yours, and real shipped work plus genuine understanding beats a polished document every time.

Common RFP mistakes

A few mistakes weaken app development RFPs and are worth avoiding. The first is making the RFP so long and rigid that it buries the actual goal and discourages good vendors from responding thoughtfully; keep it focused on what matters. The second is hiding the budget, which forces vendors to guess and makes proposals hard to compare. The third is over-specifying the technology, as covered above. And the fourth is treating the RFP as the whole process, choosing purely on the documents without ever talking to the vendors, when a conversation often reveals what a written proposal cannot.

The thread through these is that an RFP is a tool for comparison, not a substitute for judgment and relationship. The best outcomes usually come from using the RFP to shortlist, then talking to the top candidates to test understanding, communication, and fit. An RFP that gets you comparable proposals and then leads into real conversations gives you the best of both: structure and the human judgment that structure alone cannot provide. Skipping that human step is how organizations sometimes pick the best-written document rather than the best partner, and the two are not always the same, because writing a proposal and building an app are different skills.

When a lighter approach is better

Be honest about whether the formality is serving you. If you are a small business or a first-time founder building your first app, a full RFP process can be more overhead than it is worth, and a clear brief plus direct conversations with a few good partners will usually get you a better result faster, because it invites collaboration instead of rigid responses. The RFP is built for larger, more formal procurement, and forcing it onto a small, exploratory project can slow you down and push away the partners who would serve you best.

When your project genuinely needs the structure, an RFP done well, focused, honest about budget, open on the technical approach, and followed by real conversations, is a sound way to choose. A team that designs and builds under one roof, as we do, responds to a good RFP with a clear, honest proposal, or, for a smaller project, simply has the honest conversation that gets you to a clear, scoped plan faster, while keeping you in control of your code and Apple Developer Program account.
