**Short answer:** Evaluate software vendors by writing down your requirements and weights before you see any demos, sending the same short request for proposal (RFP) or question set to three to five vendors, scoring each against the same weighted criteria, verifying security, financial stability and references, and running a scripted trial with your finalists. Decide on the weighted score plus the risks you found, not on the best demo.

Vendor demos are designed to impress, and they usually do. The problem is that every vendor shows its best side, in its own order, using its own data, so comparing them afterwards is close to impossible. A light, structured evaluation fixes that. It does not need to be bureaucratic: for most small and mid sized businesses, the whole process fits in a few weeks and a few documents. This guide gives you that process, a question bank and a scoring matrix you can reuse.

## Key terms

- **RFI (request for information):** a short questionnaire used to learn what the market offers and build a shortlist.
- **RFQ (request for quotation):** a request for prices when you know exactly what you want.
- **RFP (request for proposal):** a structured request asking vendors how they would meet your requirements, at what price and on what terms.
- **Weighted scoring:** rating each vendor against criteria that carry different weights, so the most important criteria count most.
- **Due diligence:** checks on security, financial stability, references and contract terms before you commit.

## When a formal RFP is worth it

A full RFP takes effort on both sides, so use it where the stakes justify it:

| Situation | Recommended approach |
|---|---|
| Low cost tool, easy to replace, little sensitive data | Short question list and a free trial |
| Moderate cost, several teams affected | Light RFP (10 to 20 questions) and scripted demos |
| High cost, hard to replace, sensitive data, multi year contract | Full RFP, scripted demos, trial, security review and references |

As a rule, the harder a tool is to leave, the more structure the decision deserves. Zylo's 2026 SaaS Management Index reports that the average organization handles 211 SaaS renewals a year, so buying decisions made quickly often become renewals made by default.

## Step 1: Build the evaluation team

Name a decision owner and include three perspectives:

- **The people who will use the tool daily**, who judge fit and usability.
- **The person who will administer it**, who judges setup, integrations and maintenance.
- **Finance or procurement**, who judges cost, terms and vendor risk.

For tools that handle personal or confidential data, add whoever is responsible for security or privacy.

## Step 2: Write requirements and weights before talking to vendors

Write requirements in plain language, then sort them into three groups:

1. **Gates:** pass or fail conditions, such as single sign on, data residency in your region, or support for a specific country.
2. **Must haves:** essential for the job, scored on how well they are met.
3. **Nice to haves:** tiebreakers.

Then agree the weights for each scoring category. Doing this before demos is the most important step in the whole process, because it stops a polished presentation from rewriting your priorities.

## Step 3: Send the same questions to every vendor

Keep the RFP short and specific. A good structure has six sections:

1. **Company and product:** how long the product has existed, number of customers similar to you, roadmap for the next year.
2. **Functional fit:** for each must have, ask the vendor to say whether it is standard, configurable, on the roadmap or not available, and on which plan.
3. **Implementation:** typical timeline, who does the work, what you need to provide, migration tools.
4. **Security and data:** certifications or independent audit reports, encryption, access controls, breach notification, data location, data export and deletion.
5. **Support:** hours, channels, response times by severity, named contact.
6. **Commercials:** pricing for your volumes over three years, renewal terms, increase caps, minimum terms, add ons.

Ask vendors to answer in your format, not in their brochure. Comparable answers are the whole point.

## Step 4: Score with a weighted matrix

Here is a weighting that works for many business software purchases. Adjust the weights to your situation, but agree them in advance.

| Category | Weight | What a 5 out of 5 looks like |
|---|---|---|
| Functional fit | 30% | All must haves met as standard on the quoted plan |
| Usability | 15% | Users complete scripted tasks quickly with little help |
| Total cost of ownership (3 years) | 25% | Lowest realistic three year cost, including setup and internal time |
| Implementation and support | 10% | Clear plan, realistic timeline, responsive support with defined response times |
| Integrations | 10% | Native, maintained connectors to your core systems |
| Vendor viability | 10% | Stable company, relevant customers, credible roadmap |

Score each category from 1 to 5, multiply by the weight and add up. Security, data protection and exit terms are better treated as gates: a vendor that fails them is out, however well it scores elsewhere.

For the cost category, use a three year [total cost of ownership](https://businesslang.com/guides/total-cost-of-ownership-business-software/), not the list price.

## Step 5: Run scripted demos

Send finalists a demo script one week in advance, based on your real processes, and ask them to show exactly those tasks with realistic data. A script might include:

- Complete your most common daily task from start to finish.
- Handle one exception, such as a refund, a cancelled order or a staff member leaving.
- Show how an administrator adds a user, changes a permission and runs a report.
- Show the full data export.

Score immediately after each demo, individually, before discussing. Group discussion before scoring tends to follow the loudest voice.

## Step 6: Check security and supply chain risk

Software vendors are part of your supply chain. NIST's Cybersecurity Framework 2.0 includes a Cybersecurity Supply Chain Risk Management category (GV.SC), and NIST's quick start guide on the subject (SP 1305) encourages organizations to know and prioritize suppliers by how critical they are and to build cybersecurity requirements into contracts. For a small business, that translates into a short checklist:

- **Criticality:** how bad would it be if this vendor were breached or went offline for a week?
- **Evidence:** independent audit reports or certifications, not just a security page.
- **Access:** which of your data and systems the vendor can reach, and how access is controlled.
- **Incidents:** how quickly the vendor will tell you about a breach, and through which channel.
- **Subprocessors:** which other companies process your data on the vendor's behalf.
- **End of relationship:** how data is returned and deleted when the contract ends.

If the vendor will process personal data on your behalf and you are subject to the GDPR, Article 28 requires that processing to be governed by a contract setting out, among other things, its subject matter, duration, nature and purpose. Ask for the vendor's data processing agreement early.

## Step 7: Check references and vendor viability

Ask for two references that resemble your business in size and use case, and ask them:

- What surprised you after you signed?
- How did the vendor handle your biggest problem?
- What would you negotiate differently?
- Have prices or terms changed at renewal?

For viability, look at how long the company has operated, its customer base in your segment and any recent changes such as acquisitions, which can lead to price or product changes.

## Step 8: Trial with your finalists

Run a two to four week trial with one or two finalists on real work, with the people who will use the tool. Define success criteria before the trial starts, for example "a new user completes the core task without help after one short walkthrough".

## Step 9: Decide and document

Combine the weighted scores with the risks you found. Write a one page decision record covering the options considered, scores, key risks and how you will mitigate them, the price and terms agreed and the renewal date. This record is invaluable at renewal, when someone will ask why you chose this vendor.

## Step 10: Negotiate from your evaluation

A structured evaluation gives you leverage: you have a credible alternative, documented gaps and a clear view of the terms that matter. Use it to negotiate the price, an increase cap, the notice period and data terms. Zylo reports that for 61% of IT leaders, unplanned SaaS costs affected planned projects, and many of those surprises are written into contracts that were never negotiated. See our [SaaS negotiation guide](https://businesslang.com/guides/how-to-negotiate-saas-pricing-and-renewals/) and [contract checklist](https://businesslang.com/guides/saas-contract-checklist/).

## A sample RFP question bank

Copy the questions that matter for your purchase. Fewer, sharper questions produce better answers than long questionnaires.

**Functional fit**

- For each requirement below, state whether it is standard, configurable, available through an add on, on the roadmap or not available, and on which plan.
- Describe how a user completes [your most common task] from start to finish.
- What are the plan limits on users, records, storage, automations and API calls?

**Implementation and data**

- What is a typical implementation timeline for a customer of our size, and what do you need from us?
- What migration tools or services do you provide, and at what cost?
- In what formats can we export all of our data, and is there any charge?

**Security and compliance**

- Which independent security audits or certifications do you hold, and can you share the reports?
- Do you support single sign on and enforced multi factor authentication, and on which plans?
- Where is our data stored, and which subprocessors have access to it?
- How quickly will you notify us of a security incident affecting our data?
- Do you use customer data to train AI models, and can we opt out?

**Support and service levels**

- What are your support hours, channels and response times by severity?
- What uptime do you commit to, and what credits apply if you miss it?

**Commercials**

- Provide pricing for our volumes for each of the next three years.
- What is the maximum price increase at renewal, and will you put a cap in the contract?
- What are the notice period, minimum term and termination terms?

## How to handle vendor responses

1. **Normalise prices.** Convert every quote to the same seat count, billing basis and three year period.
2. **Flag vague answers.** "Yes" without detail, or "available on request", should go back to the vendor as a follow up question.
3. **Separate today from roadmap.** Score only what exists now on the quoted plan. Roadmap items are promises, not features.
4. **Record commitments.** Anything material a vendor says in writing should be referenced in the contract.
5. **Thank and inform unsuccessful vendors.** Brief feedback keeps relationships professional, and you may need them later.

## A realistic timeline for a small business

| Week | Activity |
|---|---|
| 1 | Form the team, write requirements and weights, build the shortlist |
| 2 | Send the RFP or question set; vendors respond |
| 3 | Score responses, choose finalists, send demo scripts |
| 4 | Scripted demos, individual scoring, reference calls |
| 5 to 6 | Trial with finalists, security review |
| 7 | Decision, negotiation and contract review |

## Keeping the evaluation fair

- Give every vendor the same information and the same deadline.
- Do not share one vendor's pricing with another.
- Declare any personal relationship with a vendor and step back from scoring it.
- Keep scores and notes, so the decision can be explained later.

## Scoring example

This illustrative example shows how weighted scoring works with two finalists, using the weights above. Scores are out of 5.

| Category | Weight | Vendor A score | Vendor A weighted | Vendor B score | Vendor B weighted |
|---|---|---|---|---|---|
| Functional fit | 30% | 4 | 1.20 | 5 | 1.50 |
| Usability | 15% | 5 | 0.75 | 3 | 0.45 |
| Total cost of ownership | 25% | 4 | 1.00 | 3 | 0.75 |
| Implementation and support | 10% | 3 | 0.30 | 4 | 0.40 |
| Integrations | 10% | 4 | 0.40 | 4 | 0.40 |
| Vendor viability | 10% | 4 | 0.40 | 5 | 0.50 |
| **Total** | 100% | | **4.05** | | **4.00** |

**Method.** Weighted score is the score multiplied by the weight; the total is the sum. Vendor B has more features, but Vendor A wins narrowly on usability and cost. When totals are this close, let the risks you found and the trial results decide.

## Common mistakes in vendor evaluations

- Setting criteria after the demos.
- Letting each vendor run its own demo agenda.
- Comparing list prices instead of three year cost.
- Scoring as a group before individuals have scored.
- Skipping references because the demo was convincing.
- Treating security as a score that can be outweighed by features.

A good evaluation is not about paperwork. It is about making sure the vendor you pick is the one that fits your job, your risks and your budget, and that you can explain why.

## Frequently asked questions

**Q: What is an RFP for software?**

A: A request for proposal (RFP) is a structured document that describes your requirements and asks vendors to respond in a standard format with how they meet them, pricing and commercial terms. It makes responses comparable and creates a written record of vendor commitments.

**Q: Does a small business need a formal RFP?**

A: Not always. For low cost, easy to replace tools, a short question list and a trial are enough. Use a fuller RFP when the purchase is expensive, hard to reverse, touches sensitive data or involves several stakeholders.

**Q: How many vendors should I invite?**

A: Three to five for an RFP, narrowing to two or three finalists for demos and trials. More vendors produce more paperwork without better decisions.

**Q: What is the difference between an RFI, RFQ and RFP?**

A: An RFI (request for information) gathers general information to build a shortlist. An RFQ (request for quotation) asks for prices on a clearly specified product. An RFP asks vendors to propose how they would meet your requirements and at what price.

**Q: How should I weight price in a vendor evaluation?**

A: Price usually deserves 20% to 30% of the total score, calculated as three year total cost of ownership rather than list price. Weighting price higher tends to reward tools that become expensive after year one.
