When should you fire your marketing agency? Seven signs and how to reset cleanly
Replace an agency when the problem is trust or learning, not when a long sales cycle has not paid back yet. Seven signs point to a real problem: no tracking you can verify, reporting that hides pipeline, no written expectations, nothing learned from what failed, no ownership of accounts and data, changing teams without notice and advice that always favors more spend. If you see them, audit, secure ownership, set a 30 day exit plan and brief the next partner. PlanConversion is an agency, so we state our own bias.
Key takeaways
A note on who is writing this
PlanConversion is a B2B marketing and demand generation agency, so we have an interest in this question. We have tried to write the page we would want a prospective client to read about us. If you are unsure whether the problem is the agency, the plan or the sales cycle, the checks below separate them.
Seven signs the relationship is not working
| Sign | What it looks like | What to ask |
|---|---|---|
| 1. Tracking you cannot verify | Numbers differ between the agency report, the ad platform and the CRM, and nobody can reconcile them | Show me the path from a click to a CRM opportunity for last month |
| 2. Reports that hide pipeline | Leads, clicks and impressions lead the report; opportunities are missing | What did spend produce in qualified opportunities, by campaign? |
| 3. No written expectations | Nobody can say what should be true at 30, 60 or 90 days | What should we see by day 90, and what happens if we do not? |
| 4. Nothing learned from what failed | Reports contain only good news; tests are not documented | What did you stop, and why? |
| 5. No ownership of accounts and data | The agency holds the ad accounts, analytics or creative files | Who owns the accounts, and can I have admin access today? |
| 6. Team changes without notice | The people you met are not doing the work | Who does the work now and what is their experience? |
| 7. Advice that always means more spend | Every shortfall is answered with more budget | What would you do at the same budget? |

Three things that are not reasons by themselves
- A slow first quarter in a long sales cycle. 6sense’s 2026 research put the average enterprise cycle at 10.3 months. Check leading indicators first, as in our article on judging channels in a long sales cycle.
- A change in your own targeting, offer or sales follow-up. An agency cannot fix a weak handoff.
- Lead volume falling after an agency removed low-quality traffic. Check cost per opportunity before reacting.
How to run a clean reset
- Audit first, quietly. Check who has admin access to ad accounts, analytics, tag manager and the CRM, and export what you can: reports, creative, keyword and audience lists, tracking plans.
- Secure ownership. Make sure the accounts are in your name with you as admin. Rotate shared credentials.
- Document what is known. Write down what worked, what failed and what was never tested, so the next partner starts from facts.
- Give notice according to the contract, and agree a handover: a call, files and a transition date. Keep campaigns running during the handover where they are performing.
- Brief the next partner with the 90 day standard: tracking proof, written expectations at 30, 60 and 90 days and reporting on cost per qualified opportunity.
Our guide on what a demand generation agency should deliver in the first 90 days sets out that standard.
Agency, in-house hire or a hybrid
If the problem is trust, a new agency may be the answer. If it is knowledge transfer, speed or cost, compare the options. Our comparison of agency versus in-house demand generation for enterprise teams lays out the trade-offs.
Our guide to an embedded agency team versus an in-house hire covers the middle option.
A written expectation at each stage protects you in either case.
How PlanConversion handles this
When we take over a program, we start with an access, tracking and data audit and document what we find before changing anything.

Frequently asked questions
When should you fire your marketing agency?
When you see problems of trust, learning or ownership: tracking you cannot verify, reports without pipeline, no written expectations, nothing learned from failures, no control of your own accounts and data, silent team changes or advice that always means more spend. Not when a long sales cycle has not paid back yet.
How long should I give an agency before deciding?
Judge the 30, 60 and 90 day deliverables on time, and the pipeline read after one to two quarters. Revenue takes the buying cycle, which averaged 10.3 months in 6sense’s 2026 study.
How do I leave an agency without losing data?
Confirm you are admin on the ad accounts, analytics and CRM before giving notice, export reports and creative, and agree a handover call and transition date.
Should I replace the agency or bring marketing in-house?
Compare cost, speed, expertise and management time. A hybrid or embedded team is another option. If the problem was trust and measurement, a better-governed agency relationship can fix it.
