How to Write a Software Development RFP That Gets Good Proposals

An RFP's Job Is to Make Proposals Comparable, Not Just Solicit Them

The first thing to understand about how to write a software RFP is that most of them fail at the one thing they're supposed to do: produce proposals you can actually compare against each other. If your RFP is a loosely described product idea and a request for "a proposal and a quote," you'll get back three documents with different assumptions, different scopes, and prices that look wildly different but aren't pricing the same thing. The fix isn't a longer document — it's a more specific one that constrains every bidder to answer the same structured questions against the same defined scope.

Describe the Problem, Not Just the Feature List

Lead with the actual business problem you're solving and who it's for, before you get into feature specifics. A feature list without context invites agencies to bid on exactly what's written and nothing more, which produces proposals that hit the letter of your RFP and miss the product you actually need. Give enough context — your users, your constraints, what "success" looks like for the first version — that a good team can push back intelligently on scope you got wrong, because the best signal in a proposal is often the questions and suggested changes it comes back with, not just its price.

It helps to include what you don't yet know, too, not just what you do. If you haven't decided on a specific integration, or you're genuinely unsure whether a feature belongs in phase one or phase two, say so directly rather than guessing just to fill out the document. A strong bidder will treat open questions as an invitation to advise, and their answer to an honestly-flagged unknown tells you more about their judgment than their answer to a question you'd already fully specified.

Force Specificity on Team Composition and Timeline

Require every bidder to name the actual roles that will be staffed, their seniority, and estimated hours per week — not a headcount, a real staffing plan. Require a phased timeline with milestones you can independently verify, not just a single end date. This does two things: it forces agencies who haven't actually thought through your project to reveal that in their answer, and it gives you a like-for-like way to compare proposals that might otherwise look identical on price but represent completely different levels of actual commitment.

Ask for a Fixed Set of Questions Every Bidder Must Answer

Include a short, identical question set every proposal must answer directly: how they'd approach the first two weeks, what they'd need from you to start, how they handle scope changes mid-project, what their code ownership and IP terms are, and what a past project most similar to yours looked like. This is the single highest-leverage thing you can add to an RFP — it turns marketing documents into structured answers you can actually line up side by side.

A good RFP doesn't just ask what this will cost — it asks enough specific questions that a company with no real plan can't hide that fact behind a well-designed PDF.

Sharing your budget range, even approximately, belongs in a well-written RFP too, despite the instinct to hide it and see what comes back. Withholding budget doesn't get you a more honest number — it gets you a number anchored to whatever the bidder guesses you can afford, which is a worse starting point than a number anchored to your actual constraints. A realistic range lets serious bidders tell you honestly whether your expectations and your budget are actually aligned, before either side wastes weeks discovering they aren't.

Set a Realistic Response Window and Say What Happens Next

Give bidders enough time to actually think about your problem rather than reuse a template — two weeks is usually a reasonable floor for anything beyond a small project — and tell them explicitly what your evaluation process and timeline look like after submission. Agencies invest real time in a serious proposal, and being transparent about how you'll evaluate it, and by when, gets you more thoughtful responses than an RFP that reads like it's one of fifty going out with no clear process behind it.

Don't Let Price Anchor the Evaluation

Once proposals come back, resist ranking by price first. Read the answers to your structured questions before you look at the number, because price without context is the easiest thing in a proposal to game — pad the estimate, cut corners on the roles proposed, or lowball to win the deal and renegotiate later through change orders. An RFP that's done its job gives you enough real signal in the answers that price becomes the last thing you compare, not the first.

If two proposals answer your structured questions with similar quality but very different prices, that gap is worth a direct conversation rather than an assumption in either direction — ask the cheaper bidder how they arrived at the number, and ask the pricier one what specifically justifies the premium. The answer usually reveals whether you're comparing two honest estimates of different scopes, or one realistic number against one that's going to grow through change orders later. A well-built RFP is what makes that conversation possible in the first place.
