Most Amazon agencies have a SKU ceiling.
They definitely won't tell you.
But they have one.
Their playbook works for 20 to 100 SKUs.
Above that, the wheels fall off.
Why?
A standard agency workflow looks like:
⤷ Audit every listing
⤷ Build creative for every parent ASIN
⤷ Run targeted ad campaigns per SKU
⤷ Weekly performance reviews per product
Now apply that workflow to 1,500 SKUs.
Their account managers can't do it.
So they do what every shorthanded agency does:
⤷ Optimize the top 50 SKUs
⤷ Run shotgun ads on the rest
⤷ Tell the founder to "focus on hero products"
⤷ Quietly let 90% of the catalog rot
The brand pays full retainer.
They get 5% of the work.
That's not strategy.
That's capacity hiding behind a recommendation.
Large catalogs need a different operational model:
⤷ SKU tiering by margin contribution and search demand
⤷ Templated creative systems, not one-off design work
⤷ Bulk operations on listings, not 1,500 manual edits
⤷ Ad architecture built for catalog sprawl, not 50 hero products
At Velocity Sellers we build what the rest of the industry hides from.
1,000 SKUs.
5,000 SKUs.
Catalogs that scared off every agency in the LinkedIn search.
If you're a large-catalog brand & your agency keeps telling you to "focus on hero products" - that's not advice. That's an admission.
When was the last time your agency reported on a SKU outside your top 20?
