AI Agency Reference Check Questions for Service Businesses: What to Ask Before You Sign

A reference check should tell you how the engagement actually feels

Most buyers waste reference calls.

They ask whether the agency was “good,” hear a polite yes, and learn almost nothing.

If you are hiring AI marketing help, better AI agency reference check questions focus on how the team operated once real deadlines, approvals, and underperformance showed up.

The best questions are concrete

Ask former or current clients things like:

1. What did the agency actually take off your plate?

This tells you whether the team creates real operating relief or just another layer of meetings.

2. How clear were they about what they owned?

You want to know whether responsibilities stayed obvious after kickoff.

3. What happened when something underperformed?

This is one of the best questions you can ask.

Did the agency explain the issue clearly? Did they adjust fast? Did they get defensive?

4. How fast were approvals, revisions, and follow-up handled?

Good work can still become painful if response rhythm is chaotic.

5. Would you hire them again for the same type of work?

That answer is often more honest than “Were you happy?”

What to listen for between the lines

Even when the reference is positive, pay attention to phrases like:

• “they needed a lot from us”
• “once we got aligned, things improved”
• “the strategy was strong, but implementation was slower”
• “communication depended on which person was leading the account”

Those details help you see what the engagement will actually require from your team.

What not to ask

Avoid broad prompts like:

• Were they great?
• Did you like them?
• Did they get results?

Those questions usually produce vague answers and social politeness.

Reference calls matter most when they expose operating truth

A strong reference call should leave you with a sharper picture of pace, clarity, ownership, and trust.

That is the information that helps you make a good decision before a contract turns into a cleanup project.
