Sound familiar?

You're doing the volume. Amazon's keeping the control.

On Vendor Central, the hardest problems aren't operational — they're structural. No amount of optimizing fixes them. Here's where 1P quietly costs you.

You don't set your own price

Amazon owns the retail price. When they slash it below MAP, your resellers and retail partners revolt — and on 1P there's no lever to pull.

Your margin shrinks every year

Annual negotiations exist to grow Amazon's margin by shrinking yours. Co-op, freight, and chargebacks can quietly erase 20%+ of a PO before a single unit sells.

POs and forecasts you can't trust

Order volume swings without warning, MOQs make no sense, and unsold forecast turns into penalties. You can't promise inventory to any other channel.

What changed

Amazon is quietly pushing 1P brands to 3P.

Since late 2024, Amazon has terminated thousands of smaller vendors, expanded the CRaP list, and tightened chargeback enforcement. The brands winning right now moved the right SKUs to 3P — where margins run 2–3× higher and you set your own price. One brand we worked with watched revenue slip from $1.2M to $980K after the move — and profit climb 110%. The question isn't whether to move. It's which SKUs, and how.

What you get

A SKU-by-SKU plan for what to move — and what to keep.

No generic "3P is better" advice. A real profitability model built on your actual catalog.

01 / PROFITABILITY

Which SKUs make more on 3P

We model referral and FBA fees, price control, and MAP recovery against your real 1P margins — SKU by SKU, even across catalogs of 1,000+ items.

02 / MIGRATION

A move plan that protects rank

For the SKUs that pencil out, a sequenced transition that avoids the 15–25% sales dip most brands walk straight into when they switch blind.

03 / STUCK SKUS

Creative fixes for gated SKUs

Gated, CRaP'd, or feeling locked on 1P? We've built workarounds that get brands selling — and profitable — on 3P again.

Questions

Quick answers

Do I have to move my whole catalog?

No — and most brands shouldn't. The point of the analysis is to find the SKUs where 3P wins and leave the rest on 1P. That hybrid is usually what maximizes total profit.

Won't I lose sales when I switch?

It's the number-one risk. Brands that move blind often see a 15–25% dip for 60–90 days while buy box and rank rebuild. Our migration plan sequences the switch specifically to protect that.

What if my brand is gated or stuck on 1P?

That's one of our specialties. We've built creative solutions for brands that feel locked on Vendor Central — whether gated, CRaP'd, or recently terminated — and gotten them selling profitably on 3P.

Is the analysis really free?

Yes. We'll give you a real read on your catalog and show you where the margin is. If you want us to run the migration, we can talk. If not, the findings are yours to keep.
