Hiring an agency used to feel like a project decision — you picked a team, they delivered a deliverable, and the relationship ended when the invoice cleared. That’s changing. Client-agency relationship tenure has roughly doubled since 2016, according to joint research from the ANA and the 4As, ANA: Client-Agency Relationship Tenure Has Doubled Since 2016. Agencies are looking less like vendors and more like long-term partners — which means the questions worth asking before you sign should look less like a project brief and more like due diligence on someone you’ll be working with for years.
Most pitch processes never get past price, portfolio, and chemistry. Those matter, but none of them predict how the relationship actually holds up eighteen months in. These four questions do.
Four Questions to Ask Any Agency Before You Sign
- Who specifically will be doing the work — not the pitch team? The people in the room during the pitch are frequently the agency’s most senior, most persuasive talent. They are not always the people who show up for the day-to-day execution. Ask by name who will staff the account, and ask what happens to that staffing if the account grows or a team member moves to a different client.
- What happens when the account lead leaves? Agency turnover is a fact of the industry, not a hypothetical. The real question isn’t whether it will happen — it’s whether the agency has a documented handoff process, shared institutional knowledge beyond one person’s head, and a track record of transitions that didn’t cost the client months of rebuilding context.
- How do you handle disagreement with us? Every real engagement eventually includes a moment where the agency thinks the client is wrong. An agency that only ever says yes isn’t protecting your brand — it’s avoiding an uncomfortable conversation. Ask for a specific past example of when they pushed back on a client and what happened next. The answer tells you whether you’re hiring a partner or a vendor that bills by the hour.
- What does a bad year with us look like, and how would we know? This question catches agencies off guard, which is exactly the point. A team that has thought seriously about failure modes — scope creep, missed deadlines, quality drift as an account scales — will have a real answer. A team that’s never considered it is telling you something too.
Why These Are the Questions That Matter
None of the four are about capability. They’re about durability — whether the relationship still works when the account manager who ran the pitch has moved on, when a disagreement actually happens, when a quarter goes sideways. Portfolio and price tell you whether an agency can do good work once. These questions tell you whether the relationship survives long enough for that good work to compound into something bigger, which is increasingly what the tenure data suggests clients are actually signing up for.
The Right Questions Outlast the Right Pitch
A strong pitch deck is evidence of a strong pitch team, not necessarily a strong ongoing partnership. If tenure is trending longer across the industry, the decision deserves the scrutiny of a longer commitment — not just the excitement of a good first meeting. If you want to see how we’d actually answer these four questions, that’s exactly the kind of conversation a consultation is for. Get in touch.
