The build-vs-partner question on Amazon brand management is one of the most consequential operating decisions a CPG brand makes — and one of the most poorly framed in most boardroom conversations.
The framing problem: brands typically debate this question along the wrong axis. "Should we have an in-house team or hire an agency?" That binary is neither how the decision actually works nor how the answer should be reasoned about. The real question is more subtle: which capabilities belong in-house, which belong with a partner, and what's the right governance structure between them at your specific stage of business?
I've watched this decision get made well and poorly at brands ranging from $5M to $500M. The framework below is what I push leadership teams toward when they're evaluating it. The goal isn't to produce a single answer. The goal is to produce a correct answer for the specific business — which is often a hybrid that doesn't fit neatly into "build" or "partner."
The five dimensions that determine the right answer
Run your business honestly through five questions. The clustered answers determine where you should be.
1. Strategic importance
How central is Amazon to your business strategy? Not how big — how strategic. A brand for which Amazon is 80% of revenue but a tactical channel has different needs from a brand for which Amazon is 30% of revenue but the most strategic platform.
The high-strategic-importance answer pulls toward in-house. Strategic decisions need to be made by people who are inside the company, share its incentives, and have the long-horizon perspective to make tradeoffs partners can't.
The low-strategic-importance answer pulls toward partner. If Amazon is a tactical channel, the operational depth of running it doesn't justify the in-house investment.
2. Scale
What's the volume of work? At very small scale, the fixed costs of an in-house team don't pencil out — you're paying for capacity you can't keep utilized. At very large scale, the variable costs of partner relationships start to exceed what an in-house team would cost, and the partner's account-load economics start to dilute the quality of attention.
The crossover point varies by category and complexity, but a useful rule of thumb: under roughly $5M of Amazon revenue, in-house is hard to justify economically. Above roughly $50M, partner-only is hard to justify on talent depth alone. The middle is where the real decision lives.
3. Operational complexity
How complex is the work? A brand selling 20 SKUs in a single category with steady demand patterns has dramatically different operational requirements from a brand with 200+ SKUs across multiple categories with seasonal complexity, multi-region inventory, and cross-channel coordination needs.
Complexity pulls in opposite directions. Higher complexity means higher operational depth required, which can favor partner (depth from specialization). Higher complexity also means more strategic interdependence, which favors in-house (alignment with broader operations).
The actual decision usually involves separating the strategic parts of complex operations (in-house) from the executional parts (partner). Brands that try to insource everything at high complexity get overwhelmed. Brands that outsource everything lose strategic coherence.
4. Talent availability
What can you actually hire? Top Amazon brand management talent is genuinely scarce. Building an in-house team requires not just the headcount budget but the recruiting infrastructure, the retention culture, and the willingness to lose the talent battle to bigger competitors.
Brands that can attract and retain Amazon-specific senior talent at scale have one set of options. Brands that can't — for geographic reasons, brand reputation reasons, comp structure reasons, or simply because they're competing for talent that's flowing toward larger brands — have a different set.
Honest assessment: can you actually build the team you'd need? If the answer is "probably yes if we tried hard," partner is often better. If the answer is "we're already winning the talent war in this space," in-house starts to win.
5. Time horizon
How long is your decision time horizon? Building an in-house team is a multi-year investment. Talent ramp, institutional knowledge, operational cadence — none of this comes online in 90 days. Partners, by contrast, can be operational in weeks.
If your strategic time horizon is "we need to win Q4 of this year," partner-driven execution is structurally faster. If your time horizon is "we need to be the dominant brand in our category by 2030," in-house investment compounds in ways partner relationships rarely do.
Where the answers cluster
Run a brand through all five questions. Three patterns show up.
Pattern A: Build heavy.
High strategic importance.
Above $50M Amazon revenue.
Operationally complex.
Talent advantage.
Long horizon.
These brands should run primarily in-house, with selective partner relationships for specific capabilities (creative production, specialized advertising, brand protection legal work). The in-house team is the operating brain. Partners are augmentation.
Pattern B: Partner heavy.
Lower strategic importance.
Under $25M Amazon revenue.
Operationally simpler.
Talent constraints.
Shorter horizon.
These brands should run primarily through a partner relationship, with selective in-house oversight (typically a senior brand manager or VP-level coordinator who owns the partner relationship and ensures strategic alignment).
Pattern C: Hybrid (where most brands live). Most CPG brands at scale fit somewhere between. Strategic capabilities in-house. Operational execution through partners. Specific specialized work (creative, brand protection, complex reporting) often through dedicated specialists.
The hybrid model only works when the boundaries are explicit. Without clear definition of what's in-house, what's partner, and how the seams connect, hybrids drift into either redundancy (paying for the same work twice) or gaps (work falling between the in-house team and the partner with neither owning it).
The boundaries that actually matter in a hybrid
If you're operating a hybrid model — and most CPG brands at scale should be — five boundaries determine whether it works.
1. Strategic ownership. Pricing posture, channel mix decisions, NPD priorities, brand voice — these belong in-house. Always. Partners can advise; they should not decide.
2. Operational execution. Day-to-day catalog management, inventory ordering, ad campaign management, listing maintenance — typically partner-owned at most CPG brands, with in-house oversight at the leadership level.
3. Reporting and accountability. Reports flow to in-house. Decisions flow back from in-house. The cadence is explicit (weekly operational, monthly strategic, quarterly review). Without this rhythm, partner work drifts and in-house oversight atrophies.
4. Authority lines for unusual events. Buy box loss. Pricing crisis. Account suspension. Hijacker activity. Each of these needs a pre-defined authority line: who decides, who's informed, what's the SLA. Without this, the hybrid breaks down at exactly the moments it needs to be strongest.
5. Exit conditions. What conditions would cause the partner relationship to change? What would in-house have to absorb? How quickly? Most hybrid models never define this — and discover the cost in a crisis.
The decision in practice
Most leadership teams I work with are running a hybrid without realizing it. The "agency" they hired is doing more than they realize. The "in-house team" they built is missing strategic ownership of decisions they don't realize they're making by default.
The audit that surfaces this:
List every operational decision that gets made on Amazon in a given month.
For each one, mark who actually decides — in-house, partner, or default.
For each "default" decision, decide whether the default behavior is what you'd choose if you were making the decision deliberately.
Most teams find that 20-40% of their operational decisions are being made by default, in ways they wouldn't endorse if they looked. That's the gap the boundaries are supposed to close.
The takeaway
Build vs. partner isn't a binary. For most CPG brands at scale, it's a question of which capabilities live where, what the boundaries are, and how the seams work.
The answer for your business depends on five honest assessments — strategic importance, scale, complexity, talent, time horizon. The clustering of those answers points toward build-heavy, partner-heavy, or a hybrid with explicit structure.
The brands that get this right operate with a clarity their competitors can't match. The brands that don't operate with whatever ad-hoc structure happened to grow up around their team and their partner — and pay for the structural mismatch in margin and missed strategic decisions.
Run the assessment. Build the structure. Stop letting the answer be whatever it accidentally became.
