How to Write an RFP for a Software & Hardware Project (+ Template)

Quick answer: A good software development RFP template turns a vague idea into a brief that vendors can price accurately and fast. The rule is simple: the clearer your brief, the tighter and more honest the quotes you get back. Vague briefs invite two bad outcomes — inflated prices (vendors padding to cover unknowns) or lowball bids that balloon later through change orders. Below is a copy-paste RFP / project brief covering context, hardware, software, integrations, compliance, budget and timeline — plus the mistakes that quietly wreck estimates. Fill it in once and send the same brief to every vendor.
If you are about to ask agencies or product studios to quote a build — a connected device, an app, a platform, or all three — the document you send them decides almost everything that follows. Poor or incomplete requirements are one of the most expensive problems in software: IBM's research has long pegged around 60% of rework to incorrect or incomplete requirements, and custom projects routinely run 30–50% over budget when scope is loose at the start. A strong brief is the cheapest risk reduction available to you — and it quietly pre-qualifies vendors, because good ones answer a clear brief with sharp questions rather than a generic pitch.
Do you actually need a formal RFP — or a project brief?
"RFP" (request for proposal) sounds like procurement — a long, formal document with legal boilerplate and a scoring matrix, sometimes required by larger organisations or public tenders. For most commercial software and hardware builds, that is overkill. What you really need is a project brief (also called a software development brief): two to five pages telling a vendor what you are building, why, and inside what constraints. Right-size it to the deal — a €30k app and a €400k connected-product programme should not carry the same overhead. The template below works either way: the full version for a large build, the top half as a lightweight brief.
Why does a good brief get you better quotes?
Vendors price what they can see. Every gap in your brief is a risk they either pad (raise the price to be safe) or ignore (quote low, then bill change orders once the unknowns surface). When five vendors work from different assumptions, you are not comparing prices — you are comparing guesses. A complete brief does three things:
- Makes quotes comparable. Same scope and constraints, so price differences reflect the vendor, not their interpretation.
- Surfaces risk early. Compliance, integration and hardware realities named up front get costed in, not discovered in month three.
- Filters vendors. Serious teams engage with a serious brief — the questions they ask back tell you more than their portfolio does.
What makes a good software & hardware brief?
Good briefs share a few habits. They lead with the outcome, not a feature list — "cut manual meter readings to zero" tells a vendor more than "build an app with a dashboard." They state constraints openly (budget, deadline, existing systems, regulation), because constraints are what make an estimate real. For connected products they spell out the hardware realities — environment, power, connectivity, volumes and certification — which move cost far more than any single feature. And they define done, so acceptance is not a negotiation later.
For scoping the build itself, it helps to think in stages rather than one big bang — our guide to the IoT product development process walks through that, and if you are still deciding how small the first version can be, see what a hardware/IoT MVP is.
The software development RFP template (copy-paste)
Copy everything below into a document and fill in the blanks. It covers both hardware and software, so delete the sections that do not apply. If you only need a lightweight brief, the first six sections are enough to get an accurate ballpark.
1. Company & context
- Who you are, what you do, and who the users are.
- Where this project sits in your business (new product line, cost saving, compliance, replacing an existing system).
- What has been done so far (research, designs, a prototype, nothing yet).
2. Problem & goal
- The problem in one or two sentences.
- The outcome you want, stated as a result ("reduce X", "enable Y", "launch Z by Q3").
- How you will measure whether it worked.
3. Scope & deliverables
- What is in scope (device, firmware, backend, web app, mobile app, dashboard).
- What is explicitly out of scope.
- Deliverables you expect (working device, source code, documentation, test reports, deployment).
4. Hardware requirements (delete if software-only)
- What the device must sense, do or control.
- Operating environment (indoor/outdoor, temperature, ingress rating, industrial).
- Power source and battery-life target.
- Connectivity (Wi-Fi, BLE, cellular, LoRaWAN, NB-IoT).
- Expected production volume (tens, thousands, hundreds of thousands).
- Certification / compliance targets (CE, FCC, UKCA, medical, ATEX).
- Any fixed components, form-factor or enclosure constraints.
5. Software, cloud & app requirements
- Core features, prioritised (must-have vs. nice-to-have).
- Users and roles; rough number of users.
- Platforms (web, iOS, Android) and any offline needs.
- Cloud expectations (data volume, real-time vs. batch, device management, over-the-air updates).
- Reporting, analytics or AI/ML needs.
6. Integrations & data
- Systems to integrate with (ERP, CRM, payment, ticketing, third-party APIs).
- Data you will import/export and in what formats.
- Data ownership, residency and retention requirements.
7. Constraints, compliance & security
- Regulatory context (GDPR, medical, industrial, sector rules).
- Security expectations (authentication, encryption, audit logging, penetration testing).
- Technical constraints (must use a given cloud, language, or existing codebase).
8. Budget range
- A band, not a single number ("€50k–€80k", "under €150k").
- Whether it covers build only, or also maintenance and running costs.
9. Timeline & milestones
- Target launch or any hard external deadline (trade show, contract, season).
- Key milestones and which phase you want first (PoC, prototype, MVP).
10. Success criteria & acceptance
- What must be true for you to sign off and pay.
- Performance, reliability or quality thresholds.
11. Evaluation process
- How you will choose (criteria and rough weighting).
- Proposal format you want back (approach, team, timeline, itemised cost, assumptions).
- Key dates: questions deadline, proposal deadline, decision date.
12. Contacts & submission
- Who to send questions to.
- How and where to submit.
- Decision-maker(s) on your side.

What are the mistakes that lead to bad quotes?
- No budget range. Vendors can't right-size the solution, and the proposals become impossible to compare. A range is context, not a ceiling.
- A feature list with no priorities. Ten "must-haves" means nothing is. Rank them.
- Hiding constraints. An undisclosed compliance rule, legacy system or hard deadline surfaces anyway — better priced in than bolted on.
- Skipping the hardware context. Volumes, environment, power and certification change the number more than any feature. Leaving them out guarantees a wrong quote.
- No success criteria. If "done" is undefined, every milestone becomes a negotiation.
- Inviting too many vendors. Ten quotes is not diligence; it is noise. Three to five is plenty.
- An unrealistic timeline. For hardware especially, lab certification and manufacturing are fixed costs of reality, not optional buffer.
How should you evaluate the proposals?
Send your brief to three to five vendors, not fifteen, and resist ranking the replies on price alone. Weigh:
- Understanding — did they restate your problem correctly, or paste a template?
- Relevant experience — have they shipped something comparable across the same hardware/software seam?
- The questions they asked — good vendors interrogate the brief; silence is a red flag.
- Assumptions and exclusions — a transparent list of assumptions is a sign of an honest estimate.

Do you need a separate RFP for the hardware and the software?
No — and splitting them is usually a mistake. For a connected product, the hardware and software are one system, and the integration seam between them is where projects most often fail. A single, integrated brief keeps that seam owned by someone. If yours is an IoT build, make sure the brief names the four things generic software RFPs forget: power budget, connectivity, certification, and over-the-air updates — they decide feasibility and cost far more than the app screens do.
FAQ
What is the difference between an RFP and a project brief?
An RFP (request for proposal) is a formal procurement document with legal terms and a scoring matrix. A project brief is a lean, two-to-five-page document focused on the problem, scope and constraints — and for most commercial builds it gets you accurate quotes faster.
How long should a software development RFP be?
Long enough to remove ambiguity, short enough to be read. Two to five pages suits most builds; a focused three-page brief beats a twenty-page document that buries the goal.
Should I include my budget in the RFP?
Yes — as a range. A band ("€50k–€80k") lets vendors propose a solution that fits rather than guess, and does not commit you to the maximum. It also makes the proposals comparable.
How many vendors should I send my RFP to?
Three to five. Fewer than three gives you no comparison; more than five creates noise and weak, generic responses, because vendors deprioritise long-odds bids.
What should an RFP for a hardware or IoT project include that a software RFP doesn't?
Operating environment, power source and battery target, connectivity, expected production volumes, certification targets (CE, FCC), and over-the-air update needs. These physical realities drive cost and feasibility more than features do.
