Amazon Marketing Agency vs. In-House Team: What Works Best for Growth-Oriented Brands?

Introduction: Amazon Needs Resources, but From Where?

If you want to grow on Amazon, excellent performance marketing is non-negotiable. But the question arises quickly: should you build it in-house or partner with a specialized Amazon agency?

The answer depends on your goals, pace, and team structure. This article gives you the overview you need for an informed decision.

Cost and Speed Compared

An in-house team takes time: recruiting, onboarding, tools, training. It often takes months before a functioning workflow is in place.

A specialized Amazon marketing agency brings a proven setup: processes, know-how, and a full tech stack. That saves time, avoids costly mistakes, and preserves budget.

Expertise and Scalability

Amazon changes constantly. Strong agencies have dedicated PPC teams, designers for A+ Content, and know-how for international rollouts. An in-house generalist often cannot match this depth.

Flexibility and Risk

In-house means fixed costs: salary, benefits, vacation coverage. An agency can be scaled flexibly depending on season or launch focus.

When a team member is unavailable, agencies tend to be more resilient through clear backup structures.

When Does In-House Make Sense, and When an Agency?

In-house is a fit when:

  • You want to build your own Amazon team long-term
  • You need 100% control over every detail
  • You already have Amazon expertise internally

An agency makes sense when:

  • You want to scale quickly
  • You work data-driven but lack internal specialists
  • You want to stay flexible

Conclusion: Not Either/Or, but the Best of Both Worlds

The combination of an internal brand team plus an external Amazon agency can deliver maximum impact. Clearly defined roles, clean processes, and focused performance create controlled growth.

For many of our clients, this means more revenue, less internal friction, and finally clarity in their Amazon strategy.
