Should You Run Amazon PPC Yourself or Hire an Agency?

Short answer: Run Amazon PPC yourself when you have weekly time, know break-even ACOS per product, and the catalog is small. Hire when you need a dated baseline, continuous search-term work tied to stock and ranking, or multi-format ads with clear profit reporting. Amazon Sponsored Products itself has no monthly fee from Amazon; you pay CPC. The decision is about who owns the operating system around that spend.
DIY vs agency at a glance
| Run it yourself | Hire an agency | |
|---|---|---|
| Best fit | Low complexity catalog, time to learn, clear break-even ACOS | Larger catalog, limited time, need process and reporting |
| Cost shape | Your time + ad spend | Retainer or % of spend/sales + ad spend |
| Speed to a system | Slower; you build the playbook | Faster if the agency already has one |
| Risk | Missed negatives, stockouts funded by ads | Agency that optimizes ACOS while sales or profit fall |
What you are really deciding
Amazon Ads Sponsored Products charge on a cost-per-click basis with no monthly or upfront fee from Amazon. Your budget is spent over a calendar month and is not paced evenly day to day. Products generally need to be eligible for the Featured Offer to advertise. The DIY vs agency choice is about who will own search-term harvesting, negatives, bid changes tied to stock and ranking, and a profit-based target, every week.
Stay DIY when
- You can review search terms and adjust bids at least weekly.
- You know break-even ACOS per product and will not fund ads on out-of-stock ASINs.
- Your catalog is small enough that one person can see every campaign.
Hire when
- You need a dated baseline, a written plan for days 0 to 30 / 31 to 90, and monthly reporting against profit KPIs.
- You are expanding into DSP, Sponsored Brands or other marketplaces and need one owner.
- Past agencies or freelancers chased ACOS while total sales or contribution profit fell.
Exceptions
- A strong in-house media buyer with Amazon experience can beat a weak agency.
- A “percent of ad spend” agency without a profit floor can be incentivized to spend, not to earn.
- Hybrid works: you keep strategy ownership and hire for execution, or the reverse, if roles are written down.

Follow-up questions
Is Amazon PPC hard to learn?
You can learn the console basics yourself. The hard part is tying bids to ranking, stock, contribution profit and search-term quality every week. Amazon does not publish a single “correct” ACOS; you set targets from your own margins.
When should I hire instead of DIY?
When weekly optimization time is crowded out by other work, when waste keeps returning after cleanups, when you need Sponsored Brands, DSP or multi-marketplace ads coordinated, or when you want a dated baseline and monthly accountability.
Can I keep account ownership if I hire?
Yes. Keep Seller Central and Amazon Ads in your name, grant the agency the right roles, and remove access when you leave. Do not share passwords.
