Why Your Retail Analytics Net PPM is wrong

Understanding where Amazon's estimates break down.

Shipped Revenue
Amazon's total revenue from products sold and shipped to customers.
Best source: Retail Analytics Sales report
- Shipped COGS
Amazon's cost of goods sold (or your PO cost) for products shipped to customers.
Best source: Retail Analytics Sales report
+ Contra-COGS: where the problem lies
The contra-COGS figure Amazon shows you in Retail Analytics is an estimate. Amazon allocates co-op against your products based on assumptions about your agreements. It does not reflect what you were actually billed.
Best source: Remittance details, coop backup reports
- Sales Discounts
Sales discounts that do not lower the buybox price and are applied during check-out, such as coupons.
Best source: Retail Analytics Custom Analytics report
Net PPM
Amazon's profit. Divide this value by shipped revenue to determine your Net PPM %
Best source: Calculated directly from the inputs above, not Retail Analytics

Closing the gap for drive a >10% Net PPM Gain.

Real customer data showing the difference between estimates and reality.

When we recalculate Net PPM using a brand's actual co-op deductions from remittance data, there is always a difference. For one Reason Automation customer, the difference was over $30 million in a single year.

$31.1M in co-op payments not reflected in Amazon's reported figures — found during AVN prep

Amazon's own vendor managers work from an internal tool called Turismo, which can show different PPM and sales figures than what you see in Vendor Central — even though they should match. If you've ever been in a negotiation where Amazon's numbers didn't line up with yours, this is likely why. You and your vendor manager aren't looking at the same data.

Four common reasons your contra-COGS is off.

Predictable ways Amazon's estimates diverge from reality.

Amazon's Retail Analytics estimates contra-COGS at the time products are received, before actual billing occurs. That estimate can diverge from reality in predictable ways.

01

Timing differences

Amazon estimates co-op at the time of sale. Actual billing happens later, and can be influenced by post-sale factors like customer returns.

02

Straight pays and lump-sum agreements

Fixed-dollar payments with no ASIN assignment can't be attributed properly in Retail Analytics. Amazon's estimates don't account for co-op that isn't tied to individual products in the system.

03

Misattributed agreements

If you sell across multiple categories, a single ASIN can be incorrectly associated with accruals from the wrong category, or worse: duplicate accruals.

04

Overbilling and underbilling

Amazon has the right to audit and collect underbilled co-op later, which can be disruptive to cash flow. Overbilling in your favor is also common and equally worth identifying.

Validate your net PPM with accounting-grade data

How BASIS makes Net PPM validation tractable.

BASIS ingests your Retail Analytics data and your actual remittance detail, then walks you through exactly where the gaps are — by ASIN, by agreement type, by co-op category.

01

Measure the gap with our PPM validation dashboard

BASIS compares Amazon's reported contra-COGS from Retail Analytics against your actual co-op deductions from remittance data, side by side. You see the gap immediately: the amount of the difference, in cash, by ASIN, with no manual work required.

02

Break the gap down into sell-in and sell-out

Not all co-op works the same way. BASIS separates your contra-COGS into two buckets, which have different validation paths:

Sell-in Co-op

Billed at PO receipt, as a percentage of net receipts

  • Freight allowance (FA)
  • Damage allowance (DA)
  • Standard accruals and terms
Sell-out Co-op

Billed when a unit ships to the customer

  • Price discounts and deal funding
  • Prime Day and promotional events
  • Instant rebates
03

Validate sell-in co-op by ASIN

For each ASIN, BASIS shows you the co-op rate Amazon deducted as a percentage of net receipts, alongside the agreement title from your remittance data. You can instantly see whether the rate and agreement look right, and flag anything that doesn't.

Example — ASIN-level Sell-in Validation
ASIN B09XXXXXX
Agreement Co-op Accrual 10%
Net receipts $480,000
Expected deduction (10%) $48,000
Actual deduction $61,200
Gap +$13,200 overbilled
04

Validate sell-out co-op by ASIN

BASIS surfaces every promotional agreement associated with each ASIN, including the selling price, per-unit funding amount, and total volume. You can verify that what Amazon billed matches the promotions you actually ran, and spot anything that doesn't belong.

Did a Prime Day promotion appear on this ASIN? Does the unit volume look right? Is the per-unit deal funding consistent with what you agreed to? These are questions BASIS makes answerable in seconds, not hours.

05

Take confirmed gaps into the negotiation

Once you've verified where the discrepancies are and why they exist, you have something concrete: a data-driven counter-narrative to Amazon's PPM story. Amazon will almost always ask for cost reductions or funding increases to improve PPM. A validated gap analysis changes that conversation entirely.

It forces Amazon to reconcile their own data, signals that you hold them to the same standard of accuracy they hold you to, and gives you a factual basis for pushing back on terms requests rather than simply negotiating against Amazon's numbers.

Know your real PPM before your next QBR.

BASIS gives you the validation workflow, the ASIN-level detail, and the negotiation prep infrastructure to go into AVN with accurate data. Talk to our team to see it for your account.
