Co-Op Agreement

Amazon & D2C glossary · Harpy Media

A Co-Op Agreement is the annually negotiated contract clause in a 1P vendor relationship where the vendor agrees to fund part of Amazon’s marketing and operational costs — a percentage-based deduction from invoices that pays for placements, promotions, freight allowances, and damage coverage.

What is Co-Op Agreement?

A Co-Op Agreement is the annually negotiated contract clause in a 1P vendor relationship where the vendor agrees to fund part of Amazon’s marketing and operational costs — a percentage-based deduction from invoices that pays for placements, promotions, freight allowances, and damage coverage.

It’s the contractual container for Contra COGS: the piece of paper (and the annual negotiation around it) that decides how much of your wholesale revenue comes back to fund the channel. Managed well, co-op buys real growth — placements and promo support a vendor couldn’t buy otherwise. Managed on autopilot, it’s the largest silent line-item in the vendor P&L.

What the money buys (and how to judge it)

Typical uses: on-site merchandising (category page features, seasonal campaign inclusion), advertising formats Amazon runs on the brand’s behalf, email and off-site placements, enhanced content features, and operational coverage (freight, damages). The judgment test for each line: is it tied to named, measurable support, or is it an undifferentiated percentage that vanishes into the retailer’s margin? The same total spend can be a marketing plan or a tax, depending entirely on what’s itemized.

The annual rhythm of managing it

Co-op terms are set (and re-set) in Annual Vendor Negotiations. The professional cadence: all year, track what co-op actually funded and what it delivered (placements received, promo lift measured, remittances reconciled against terms — deduction errors are common); before AVN, build the position — what you’ll fund, tied to what, at what rates, backed by your performance data; at AVN, trade deliberately — growth support you want versus percentages you’re retiring; after, audit every remittance against the signed terms. The vendors who negotiate well are the ones who arrive with the receipts.

In practice

A vendor enters AVN with a delivery log: last year’s co-op funded $140k of placements, of which trackable promo weeks drove +34% velocity on funded ASINs, but $60k of the total was unitemized. The negotiation keeps the performance-tied funding, retires half the unitemized block, and caps the damage allowance at actuals. Same headline co-op number, materially better composition — and the next year’s growth budget buys more growth per dollar.

How Harpy Media helps

We run co-op like a media budget — itemized, measured, reconciled, and renegotiated with evidence. Vendor margin is defended at the clause level.
