At some point, every fashion brand that is spending seriously on paid media faces the same question: do we continue working with an agency, or do we build this capability in-house?
The answer is different for different brands at different stages. But most brands approach the decision with an incomplete picture of what each option actually costs.
What In-House Actually Costs
The visible cost of building an in-house paid media team is the salary. One media buyer, maybe a creative strategist, maybe a data analyst. That's a number that's easy to calculate and compare against an agency retainer.
The invisible costs are higher. The time and cost of recruitment — finding people with genuine paid media expertise in fashion is not simple. The ramp-up time before a new hire is performing at the level needed. The cost of knowledge gaps — a single in-house media buyer cannot match the breadth of exposure that an agency team running multiple accounts across the category develops continuously. The management overhead.
The in-house option also removes access to the cross-account data and the collective learning that an agency develops by working across a portfolio of brands in the same space.
What an Agency Provides Beyond Execution
A good paid media agency is not a service provider. It is a strategic partner with a depth of category expertise that an in-house team takes years to develop, and a perspective on what's working across the market that no single brand's data can produce.
For fashion brands that are not yet at the scale where a full in-house team is justified, this partnership is often the highest-return investment available in the marketing budget.
