Where 1P margin leaks, and how we plug it
| Where margin leaks | What happens | What we do |
|---|---|---|
| Chargebacks | Amazon deducts for late or inaccurate shipments, labelling and routing errors. | Find the root causes, fix them upstream and dispute invalid charges. Read the chargeback guide. |
| Shortage claims | Amazon records fewer units received than you shipped and deducts the difference. | Gather proof of delivery and dispute valid claims. Read the shortage claims guide. |
| Co-op and allowances | Agreed co-op and allowance terms are applied to invoices, sometimes inaccurately. | Audit deductions against your agreement and challenge mismatches. Read the co-op audit guide. |
| Cost price increases | Requests to raise your wholesale cost are rejected by default. | Build the evidence and timing for the request. Read the cost price guide. |
| Purchase order cancellations | Orders are cancelled or reduced, which hurts availability and rank. | Diagnose the cause and correct the data behind it. Read the PO guide. |
What we do, and how often
| When | What we do |
|---|---|
| Daily | Purchase order acknowledgements, inbound and ASN accuracy, stock and availability alerts. |
| Weekly | Chargeback and shortage review with disputes filed, advertising review and a written performance report. |
| Monthly | Catalog and content updates, deduction and co-op reconciliation, pricing and margin review. |
| Quarterly | Annual Vendor Negotiation preparation, forecast and promotion planning, review of new marketplaces. |
Vendor Central, Seller Central or both
Vendor Central (1P)
Amazon buys your stock wholesale and sells it as the retailer. Amazon controls the retail price, you invoice Amazon, and margin depends on terms, deductions and negotiation.
Seller Central (3P)
You sell directly to customers, set your own prices and pay Amazon fees. You keep more control, and take on more of the operational work.
Both together
Many brands run a hybrid. We decide which ASINs perform best in each channel and keep pricing, content and advertising aligned across both.

On Vendor Central (1P), Amazon buys your products wholesale and sells them as the retailer, so Amazon sets the retail price and you invoice Amazon. On Seller Central (3P), you sell directly to customers, set your own prices and pay Amazon fees. Many brands run both, and we manage the two so pricing, content and advertising stay aligned.
We audit your chargeback history, shortage claims, co-op and allowance deductions, cost-price history and purchase-order performance to see where margin leaks and which causes can be fixed at the source.
