What's Inside
— 01 —
Every item across 8 categories: Financial Verification, ASIN & Product Analysis, Traffic & PPC, Supply Chain & Inventory, Amazon Account Health, Seller Verification & Deal Structure, Market & Competition, and Final Go / No-Go.
— 02 —
Six items that end the deal immediately — no negotiation, no workaround. Prior account suspension. Brand Registry not fully transferable. Open documentation requests on ASINs. These are not yellow flags. They are stops.
— 03 —
When the due diligence window is closing and you have 48 hours, these are the 10 items that matter most. Ranked by the probability they reveal a fatal flaw before you wire money.
— 04 —
Not guidelines. Actual decision rules: 26% minimum net profit margin. TACoS ceiling of 25–30%. Single parent ASIN revenue concentration capped at 80%. Inventory older than 6 months valued at $0. These numbers are non-negotiable.
The Real Cost
Operator Add-Back
Before
$40K overpaid
Operator add-back accepted at face value. Someone has to run the business — no one does it for free. You paid for a salary that doesn't exist.
After
$40K saved
Add-back challenged. Operator cost modeled correctly. Price renegotiated before close. The checklist item is explicit: verify every add-back with a real market rate.
ASIN Concentration
Before
One ASIN = 90% of revenue
Acquisition closes. Six months later, Amazon suppresses the listing for a policy violation. Revenue drops 90% overnight. No recovery path.
After
Deal passed
Single parent ASIN revenue concentration above 80% is a hard stop. The checklist flags it in the first 30 minutes of due diligence. Deal never moves forward.
Account Health
Before
$200K acquisition, $60K loss
Supplements business acquired. Amazon begins flagging documentation requests on multiple ASINs post-close. Business returned. Final loss: $60K.
After
Open flags = instant dealbreaker
Open documentation requests on any ASIN are now a dealbreaker. This item was added after the $60K loss. It is item 1 in the Amazon Account Health category.

Every item in this checklist came from a real deal. Some of them came from deals I lost money on. The $60K loss on the supplements acquisition is in here. The $300K deal I walked away from is in here. Use it before you wire money.
