Your Vendor Central Net PPM is wrong.
We help you find the truth.
$31 million in contra-COGS missing from Retail Analytics Net PPM for a global consumer brand. Amazon uses your Net PPM as a starting point for negotiation. What if their proposal is based on bad data? Learn how to validate Amazon's PPM math and build leverage for your next negotiation.
See how BASIS finds the gapWhen 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.
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.
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.
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.
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.
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.
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.
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.
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.
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:
Billed at PO receipt, as a percentage of net receipts
- Freight allowance (FA)
- Damage allowance (DA)
- Standard accruals and terms
Billed when a unit ships to the customer
- Price discounts and deal funding
- Prime Day and promotional events
- Instant rebates
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.
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.
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.
