How to Fire Your Marketing Agency

How to Fire Your Marketing Agency (and Bring the Work In-House Without Breaking Performance)

Many leadership teams eventually ask the same question:

“How do we fire our marketing agency and bring the work in-house?”

The honest answer is uncomfortable — and important:

Most brands aren’t firing agencies.
They’re outgrowing them.

In-housing marketing isn’t a cost-cutting exercise or an act of rebellion. It’s a growth stage. When handled poorly, it creates chaos. When handled well, it creates clarity, speed, and ownership.

This article explains when to fire an agency, what to bring in-house, and how to build an internal marketing team without losing performance.

When Should a Company Fire Its Marketing Agency?

Companies usually consider firing their agency when one or more of these symptoms appear:

  • Conflicting reports and unclear performance truth

  • Slow decision-making despite high spend

  • Knowledge living outside the company

  • Over-dependence on external vendors for core decisions

  • Leadership losing confidence in marketing visibility

In most cases, the agency didn’t suddenly fail.

The organization simply matured beyond an outsourced ownership model.

This is the moment when brands begin exploring bringing marketing in-house.

Agency vs In-House Marketing: Which Is Better?

This is one of the most searched questions — and also the wrong framing.

The real answer is:

Agency vs in-house marketing is not a choice. It’s a design problem.

Agencies are strong at:

  • Channel execution

  • Specialized expertise

  • Scale and speed

In-house teams are strong at:

  • Ownership and accountability

  • Context and institutional knowledge

  • Faster, cross-functional decisions

The mistake companies make is outsourcing ownership, not execution.

What Marketing Functions Should Be Brought In-House?

Another common search question is:

“What should we bring in-house vs keep with agencies?”

Here’s the practical answer.

Functions that should usually move in-house first

  • Marketing strategy and planning

  • Performance ownership and goal-setting

  • Analytics, measurement, and reporting

  • First-party data and martech governance

  • Budget allocation and prioritization

Functions that often stay external

  • Paid media execution at scale

  • Creative production bursts

  • Platform-specific specialists

  • Short-term or experimental channels

In-housing execution without in-housing decision authority is why most transitions fail.

How to Build an In-House Marketing Team

If you’re searching “how to build an in-house marketing team”, avoid this mistake:

Do not copy an agency org chart.

Internal marketing teams need to be designed around:

  • Business outcomes

  • Decision velocity

  • Data ownership

  • Cross-functional alignment

The most effective in-house teams are systems thinkers — not channel silos.

Fewer specialists.
Clear ownership.
Strong data literacy.

Why Reporting Must Change Before You Fire an Agency

One of the clearest indicators that a company is ready to go in-house is broken reporting.

If leadership can’t confidently answer:

  • What’s working?

  • What’s driving growth?

  • What decisions should we make next?

Then changing vendors won’t help.

Before transitioning work in-house, companies must rebuild reporting around:

  • A single source of truth

  • Clear metric ownership

  • Decision-ready insights, not dashboards

This step alone prevents most failed in-housing efforts.

How to Transition from Agency to In-House (Step-by-Step)

The strongest transitions follow this order:

  1. Redesign the marketing system

  2. Clarify ownership and decision rights

  3. Rebuild reporting and data foundations

  4. Hire internal capability gradually

  5. Reposition agencies into execution roles

  6. Transfer knowledge — not just tasks

This approach preserves performance while reducing dependency.

The Most Overlooked Risk: Knowledge Loss

One of the biggest fears leaders have when firing an agency is losing momentum.

That fear is valid.

Execution can be replaced.
Knowledge cannot.

Successful transitions include deliberate:

  • Documentation

  • Context transfer

  • Strategic rationale

  • Advisory overlap

Without this, teams inherit tools without understanding — and performance regresses.

Is In-Housing Cheaper Than Using an Agency?

This is another high-intent search.

Sometimes yes.
Often no — at least not immediately.

But cost is the wrong metric.

In-housing is about:

  • Control

  • Speed

  • Accountability

  • Long-term resilience

The ROI comes from better decisions, not lower line items.

A Better Way to “Fire” an Agency

The best companies don’t abruptly fire agencies.

They:

  • Reduce dependency over time

  • Move ownership internally

  • Keep agencies focused on execution

  • Maintain continuity during the transition

The result isn’t independence for its own sake.

It’s marketing maturity.

What I Advise On

This transition is the work I advise on.

I help leadership teams:

  • Decide what stays external vs moves in-house

  • Design the internal marketing organization and data stack

  • Rebuild reporting so performance is visible and trusted

  • Transition knowledge — not just execution

Not to disrupt growth — but to support it.

Final Answer: Should You Fire Your Marketing Agency?

If you’re asking that question, the better one may be:

“What does our marketing organization need to become next?”

Handled poorly, in-housing creates chaos.
Handled well, it creates clarity, speed, and confidence.

That’s the difference between replacing vendors
and building a system the company actually owns.
