How to Make Vendors Squirm (and Why You Should)
Most vendor evaluations are theater. You fill out a questionnaire, they attach a document, both sides sign off, and nobody actually learned anything useful.
There’s a better approach. It involves making vendors uncomfortable on purpose.
Ask the Questions They Hope You Won’t
The goal isn’t to fail vendors. It’s to see how they handle pressure.
Good questions sound like: “Walk me through exactly what happens to our data when we offboard.” Or: “Who specifically owns the integration when something breaks at 2am?” Or: “What leverage do we actually have in the contract if uptime falls short?”
When a vendor can’t answer confidently, or needs to “get back to you,” that tells you more than any polished deck. You’re not being hostile. You’re finding out whether they actually know their own product.
Get Technical Stakeholders in the Room Early
Vendor evaluations fail most often when the people doing the buying aren’t the people who will operate what gets bought.
The sales team tells a good story. The people who will own the integration know where the bodies are buried. Get them in the same room as the vendor’s technical team before any contract is signed.
Are the APIs compatible with what you actually have? Is the data schema going to cause six months of cleanup work? Is their documentation real, or aspirational? These questions don’t get asked in a business review. They get asked in a technical conversation that happens too late.
Use the Evaluation as Leverage
Your evaluation period is the most leverage you will ever have over a vendor. Once the contract is signed, that leverage drops significantly.
Use it. Ask for customizations. Push on pricing. Request access to their roadmap. Get the integrations you need in writing as part of the deal. Vendors expect to be pushed during evaluation. Most buyers don’t bother.
The vendors I’ve seen treated like partners during evaluation turn into the most accountable ones after the deal closes. They remember who paid attention.
The Hidden ROI
When vendor evaluation is done seriously, you get more than a signed contract. You get fewer integration surprises. Shorter time to value. Better contract terms. And a vendor relationship that starts with mutual respect rather than mutual confusion.
Most of the operational failures I’ve seen with vendor relationships were visible during the evaluation. The warning signs were there. Someone just wasn’t asking the right questions.
Make vendors squirm during evaluation. It’s the most useful thing you can do for a relationship that’s about to cost you a lot of money.
