How to Evaluate an AI/Software Vendor Before You Sign Anything

Choosing a software or AI vendor is a decision most business owners make a handful of times, ever. Vendors, meanwhile, make their pitch every week. That imbalance means the pitch is usually far more polished than your ability to evaluate it. Here's how to close that gap.

Ask to see something working, not something described

The single most useful question you can ask is: can you show me this working on data similar to mine, not a generic demo, something close to my actual situation. A vendor confident in their ability will usually be willing to build a small proof before asking for a large commitment. A vendor who resists this and pushes straight to a full proposal is telling you something.

Ask what happens with messy, real-world input

Sample data in a demo is almost always cleaner than reality. Ask directly: what happens when the input is messy, inconsistent, or doesn't match the format you expect. A vendor who has a real answer, involving review steps, error handling, or graceful fallback to a person, understands the problem. A vendor who says it will "just work" hasn't tested it against anything real yet.

Ask about pricing structure, not just the number

The number matters less than the structure behind it. Is this a one-time build you own, or an ongoing subscription that continues indefinitely. Does the price change based on volume, and if so, how. What happens if the scope needs to change partway through. A vendor who can explain their pricing logic clearly is more trustworthy than one who just gives you a total.

Ask who actually owns the result

If they build something custom for your business, do you own it outright, or are you locked into their platform indefinitely. This matters enormously for long-term cost and flexibility. Being locked into a vendor's platform isn't automatically bad, but you should know which situation you're entering before you sign anything.

Ask what maintenance actually looks like

Nothing built once runs forever without adjustment. Ask what breaks this kind of system typically, how often it needs attention, and what that costs going forward. A vendor without a real answer here likely hasn't supported a system like this long-term yet.

Ask for a reference you can actually talk to

Not a testimonial quote on a website, an actual person you can call who used this vendor for something similar to what you need. If a vendor can't produce this, especially if they claim years of experience, that's worth noting.

Notice how they respond to "let's start small"

A vendor who's confident in their work is usually comfortable proving it on a small scale first. A vendor who insists on a large upfront commitment before showing you anything real is asking you to trust the pitch instead of the evidence. The confidence to start small and let the result speak is one of the clearest signals of a vendor worth working with.

The underlying principle

Every one of these questions comes back to the same idea: trust what you can see working, not what you're told will work. A vendor willing to prove it before asking you to commit is showing you far more than any proposal document can.
