Amazon Vendor Central management and the 1P vs 3P decision.
We help brands decide how to sell on Amazon and then run the model they choose.
Selling first party through Vendor Central means Amazon buys your inventory wholesale and resells it. Selling third party through Seller Central means you stay the seller of record. Theory Road runs its own Seller Central accounts with Brand Registry, so we know the 3P side from the inside, and we manage the 1P side for brands Amazon has invited: purchase orders, operational chargebacks, shortage claims, co-op and allowance terms, content and advertising. This page is for vendors whose margins are leaking into deductions, and for brands weighing whether to move to 3P, stay 1P or run a deliberate hybrid.

Where Amazon Vendor Central pays off, and where it stalls.
Vendor Central is invitation only. Amazon's retail team invites a brand to become a supplier, and the relationship runs on purchase orders: Amazon forecasts demand, sends POs, and you confirm, ship to its fulfillment centers and invoice. Amazon sets the retail price. In exchange for the volume and the sold by Amazon badge, you agree to terms that usually include co-op or marketing funds, damage and freight allowances and payment terms, and those terms are negotiated and revisited, often every year. Seller Central is the opposite: you set price, own the listing and inventory decisions, pay fees and keep the customer relationship.
Where vendors get stuck is in the money that never shows up. Operational chargebacks for ASN errors, labeling or carton issues are deducted automatically. Shortage claims appear when Amazon records receiving fewer units than you invoiced, and unless someone disputes them with proof of delivery inside the window, they stand. POs swing without warning, Amazon matches lower prices elsewhere on the web and then asks for margin support, and co-op terms creep up at negotiation. None of it is visible on a sales dashboard, so a vendor can grow revenue while net margin quietly shrinks.
We start with the remittances, not the storefront. We reconcile invoices, receipts, deductions and payments to find what is being lost and why, fix the upstream causes in shipping and ASN data, and dispute what is disputable with documentation. Then we look at the model. Some catalogs belong in 1P, some belong in 3P, and many brands do best with a hybrid split by ASIN or channel. We map pricing control, margin after terms and fees, fulfillment cost and brand control for each path, so the decision is made on numbers rather than habit.

Amazon Vendor Central and 1P management, scoped to the result.
1P vs 3P model review
A per ASIN comparison of net margin after Vendor Central terms and deductions versus Seller Central fees and fulfillment cost, with pricing control, brand risk and cash flow laid out side by side.
Deduction and shortage recovery
Reconciliation of invoices, receipts, chargebacks and remittances, then documented disputes for shortage claims and operational chargebacks within Amazon's dispute windows, plus fixes to the causes upstream.
Purchase order and ASN operations
PO confirmation discipline, fill rate, ASN accuracy, carton and label compliance and routing requests, so chargebacks stop at the source and Amazon's forecast keeps ordering.
Terms negotiation support
Analysis of co-op, allowances, payment terms and margin requests before annual negotiation, with the numbers you need to push back or trade terms for commitments that matter.
Content and advertising for 1P
A+ content, images, titles and variation structure maintained through Vendor Central, and Sponsored Products, Sponsored Brands and DSP run against the same retail calendar.
1P to 3P or hybrid transition
Planning and executing a move to Seller Central or a split model: account setup, Brand Registry, inventory sell-through, listing ownership, fulfillment choice and a pricing plan to avoid channel conflict.
Where Amazon Vendor Central setups break.
The problems we are most often hired to fix, in the order they tend to cost money.
Accepting deductions by default
Shortage claims and chargebacks are netted from payments automatically. Vendors who never reconcile remittances against invoices and proof of delivery lose money that could have been recovered inside the dispute window.
Treating terms as fixed
Co-op, allowances and margin support are negotiated. Brands that sign the renewal without modeling net margin per ASIN often find their best sellers are the ones losing money after terms.
Uncontrolled price matching
Amazon retail matches lower prices it finds elsewhere online. A discount on your own site or a reseller's store can drag the Amazon price down and trigger requests for margin support.
Switching models overnight
Stopping POs abruptly to move to 3P leaves Amazon holding inventory, confuses listing ownership and can cost the Buy Box during the gap. Transitions need a sell-through and cutover plan by ASIN.

A good fit
- Brands Amazon has invited to Vendor Central whose revenue is growing but whose net margin after deductions is not.
- Vendors preparing for annual terms negotiation who need a per ASIN margin model before they sign.
- Brands weighing a move from 1P to 3P or a hybrid split and wanting operators who run Seller Central daily.
- Teams whose Amazon work is split between sales, logistics and finance with nobody owning the whole account.
Probably not a fit
- Brands that have not been invited to Vendor Central should start on Seller Central; invitations come from Amazon.
- If you need a law firm or a contingency recovery firm for large historic claims, hire one; we work current operations.
Pricing, plainly.
Vendor Central has no subscription fee. Amazon's economics sit in the wholesale price you invoice and in the negotiated terms: co-op or marketing funds, allowances, payment terms and any margin support. Seller Central, by contrast, charges a monthly Professional plan fee plus referral fees and optional fulfillment fees. Our engagement starts with a fixed-scope audit of deductions, terms and the 1P vs 3P comparison. After that we either manage the vendor account and advertising monthly or run a scoped transition project and hand over. We quote after a short call, with monthly work month to month after an initial term, and we do not take a percentage of recovered deductions.

Hiring help with Amazon Vendor Central.
- Are you an Amazon partner?
- We run our own Amazon Professional Seller accounts with Brand Registry and publish as an Amazon Associate, so we operate Seller Central with our own inventory and money. We are not an Amazon Ads verified partner and nobody pays us to steer brands toward 1P or 3P. We recommend the model that leaves you the most margin and control for your catalog.
- What is the difference between Vendor Central and Seller Central?
- In Vendor Central, you are a supplier: Amazon issues purchase orders, buys your inventory wholesale, sets the retail price and sells to the customer. In Seller Central, you are the seller: you set price, own inventory decisions, pay referral and optional fulfillment fees, and keep more control over the brand. Vendor Central is invitation only; Seller Central is open to any qualified business.
- Is 1P or 3P better?
- Neither wins everywhere. 1P can suit brands that value large, simple wholesale orders and are comfortable giving up retail price control. 3P usually gives better margin visibility and pricing control, but you carry inventory, advertising and fulfillment decisions. Many established brands run a hybrid, keeping some ASINs in 1P and others in 3P, with clear rules so the two do not compete.
- Can shortage claims really be recovered?
- Often, when the shipment was delivered as invoiced and you can prove it. Disputes need proof of delivery, carrier documentation and accurate ASN and carton data, and they must be filed within Amazon's dispute window. Recovery depends on the quality of your shipping records, which is why we fix ASN and labeling accuracy at the same time as we dispute past claims.
- Can we leave Vendor Central for Seller Central?
- Yes, but plan it. We map which ASINs move, set up or clean up Seller Central and Brand Registry, choose fulfillment, let Amazon sell through its existing inventory, and time the pricing so the listing does not lose the Buy Box or confuse shoppers. A cold stop on POs creates stockouts and listing ownership problems that can take months to settle.
