How to Evaluate an Agentic AI Vendor: 10 Questions to Ask Before You Sign a Contract
Before you sign an agentic AI contract, ask these 10 vendor evaluation questions covering data grounding, guardrails, pricing, and lock-in risk.
Agentic AI is about to be everywhere, and just as fast, a lot of it is about to get canceled. Gartner predicts AI agents will land in 40% of enterprise applications by the end of 2026. It also predicts that 40% of those projects will be scrapped by 2027, for the same three reasons every time: runaway costs, unclear ROI, and governance failures.
That's not a technology problem. It's a vendor evaluation problem. Most companies that end up canceling an agentic AI project didn't get fooled by bad AI; they got fooled by a good demo. The gap between a scripted proof-of-concept and an agent operating unsupervised on your actual data, at your actual scale, with real customers on the other end, is where most agentic AI vendors quietly stop being able to answer questions.
Before you sign anything, here are the ten questions worth asking, and the answers that should make you nervous.
How is your AI grounded in our data, and what happens when it doesn't know something?
Every agentic AI vendor will tell you their agent is “grounded.” Ask what that means technically. Is it reading from a live, governed data source, or a static knowledge base updated manually? Then, ask what the agent does when it hits a gap. A vendor with a real answer says, “it escalates to a human.” A vendor without one says, “it won't happen often.”
What actually happens when the agent gets it wrong?
It's not “how do you prevent errors”. Every vendor prevents errors in a slide deck. Ask for the actual failure path: does the agent notify someone, log the action, auto-reverse it, or just keep going? This is the single best question for separating agentic AI vendors who've operated in production from ones who haven't.
Who owns the data, prompts, and outputs, during the contract and after it ends?
Agentic AI contracts are newer and messier than typical SaaS agreements, and data ownership terms vary wildly. Get explicit answers on who owns the prompt libraries you build together, whether your data trains their model, and what happens to your configurations if you leave. This is where vendor lock-in gets built in, quietly, in section 14 of a contract nobody reads closely.
How do you price this, and what happens when usage spikes?
Agents run continuously, not on a schedule, which is exactly why “runaway costs” made Gartner's list of top cancellation reasons. Ask for pricing under a heavy-usage scenario, not just the pilot tier, and get a number in writing for what happens if volume triples.
What guardrails and human-approval points are built in, not bolted on?
There's a real difference between a platform designed with governance from the ground up and one where compliance was added after a customer asked for it. Ask to see the guardrail configuration screen, not just hear about it.
Not sure how your own shortlist would hold up against questions like these? A vendor-neutral Agentforce readiness assessment can tell you honestly where your data and governance stand before you're the one signing a contract you can't get out of.

A polished demo tells you almost nothing. Ask for a reference customer in your industry, at a similar scale, doing a similar task and ask to talk to them directly, not just read their case study.
How portable is this if we switch vendors in two years?
Every agentic AI vendor wants to be the last one you evaluate. Ask directly what it would take to move off their platform: can you export your configurations, prompts, and workflows in a usable format, or does switching mean rebuilding from zero? A vendor who gets defensive here is telling you something.
What's your security and compliance posture for autonomous actions?
An AI agent that can take action, issue a refund, send an email, adjust a bid, is a different risk category than one that only answers questions. Ask specifically how autonomous actions are logged, audited, and permissioned, and whether that meets your industry's compliance requirements, not just general SOC 2 language.
How do you measure ROI, and will you commit to a metric?
“Unclear ROI” is the second most common reason agentic AI projects get killed. A vendor confident in their product will agree to a specific, measurable success metric before you sign, case deflection rate, time saved, error rate, whatever fits your use case. A vendor who won't commit to one is telling you they don't expect to hit one.
What does support look like after the contract is signed, not during the sales cycle?
Ask who you'll actually be working with three months post-launch. Many agentic AI vendors staff the sales cycle with their best people and then hand you off to a generic support queue. Get names, response-time commitments, and an escalation path in writing.
None of these questions require you to be a data scientist. They require you to ask for specifics instead of accepting confidence. The agentic AI vendors worth signing with will have real answers to all ten, usually with a story attached. The ones worth walking away from will have a version of “we're working on that”, which, six months into a contract, tends to become the whole story.
If you're not sure how your own data and governance setup would hold up under these questions before you even get to vendor selection, that's worth answering first. A vendor-neutral readiness assessment, the kind that tells you honestly whether you're ready to deploy an agent at all, is a cheaper place to find that out than a canceled contract eighteen months in. It's the same lens we apply across our own agentic AI services.
