A vendor demo is a performance. The data is clean, the screens are pre-built, and the presenter has clicked through the path a hundred times. That is not dishonest, it is simply what demos are. Your job is to turn the performance into evidence about how the product behaves with your data, your processes, and your people.

If you already have a scorecard to rank vendors, this is the step that feeds it honest scores.

Take Control of the Script

Vendors default to their strongest features. Reverse that by sending three to five scenarios in advance, drawn from real work. Not “show us reporting” but “show us how a sales manager sees pipeline slipping from last quarter’s forecast, by region, and drills to the deals behind it.”

Good scenarios share a few traits. They are specific, they cross at least two teams, and at least one includes an awkward case from your own world, such as a deal with multiple decision makers, a customer with several legal entities, or a renewal that changes mid-term. Give the same scenarios to every vendor so the comparison is fair.

Ask the vendor to perform them live, with someone from your team driving a few steps. If a feature needs a consultant to configure it for ten minutes, you want to know that.

Listen for How Things Get Done

Watch the mechanics, not just the outcome. Ask: Is this standard configuration, or custom code? Who would build this after we sign, and roughly how long does it take? Does it survive upgrades? Phrases like “we can do that with a partner” or “that’s on the roadmap” are not wrong, but they are not features you can use today. Note them as such.

Questions Worth Asking Every Vendor

• How does pricing change as we add users, modules, data volume, or API usage?
• What are the platform limits that customers of our size typically meet first?
• How do you handle data export if we leave, and in what formats?
• What does a typical implementation look like for a company like ours, and what usually goes wrong?
• How are releases delivered, and how much control do we have over timing?
• Can we speak to a customer with a similar setup, and one who has been live for over a year?
• What does support include, and how are priority issues handled?

Write answers down and ask for important claims in writing. Details such as limits, service levels and security certifications should be verified against current vendor documentation, not memory of a meeting.

Structuring a Proof of Concept

A proof of concept (POC) is worth the effort when a decision is large, and you have two finalists. Keep it small and time-boxed. Pick the riskiest requirements, not the easiest, and define in advance what success looks like.

POC Element	What to Define Up Front
Scope	Two or three high-risk scenarios, not the whole system
Data	A masked, representative sample including messy records
Users	Real end users, not only the project team
Duration	A fixed window, with a decision date
Success criteria	Pass/fail statements agreed before starting
Effort	Who from each side, and how many hours

Use your own data wherever you can. Clean sample data flatters every product. Messy real-world records reveal how the system handles duplicates, odd formats, and missing values.

Include the People Who Will Live With It

Bring in a couple of ordinary users: a rep, a service agent, an administrator. Let them try tasks without coaching and note where they hesitate. Executives choose on feature lists. Users decide on whether it feels fast and obvious. Both matter, but the second determines adoption.

Also put your integration lead in the room. Ask them to examine API documentation and try connecting one real system, even roughly. Integration surprises are expensive late and cheap early.

A Hypothetical Example

A distribution business shortlists two CRM platforms. Both demos look excellent. The team then runs a two-week POC using a masked export of their customer data, which includes accounts with several billing entities. One platform handles the hierarchy with standard configuration. The other requires a custom object and a partner estimate, which the vendor had not mentioned.

Neither result appeared in the demo. The scorecard weights shifted accordingly, and the decision became clear, even though the nicer-looking demo belonged to the second vendor.

Keep Negotiating Separate From Evaluating

Do not let pricing talk bleed into scoring. Score functional fit, integration, usability and risk first, then compare commercial terms. Otherwise a discount can quietly buy a better score for a worse product.

Frequently Asked Questions

How many vendors should reach the POC stage? Usually two. More becomes costly for you and for the vendors, who may stop investing effort if their odds seem slim.

Should we pay for a POC? Some vendors provide trial environments at no charge, others charge for assistance. Clarify costs and effort expectations before you begin.

What if the vendor refuses to use our scenarios? Treat that as a signal. A vendor confident in fit should be willing to show how the product handles your real work.

How do we avoid bias toward the best presenter? Use a standard scorecard completed independently by each evaluator before any group discussion, with scores tied to observed behaviour.

When do we involve security and legal? During shortlisting, not after selection. Security reviews and contract terms can take longer than the technical evaluation.

Next Step

Draft three scenarios from your own recent work and send them to your shortlisted vendors before the next demo is scheduled.
