The starting point
A mid-market CPG brand in the personal-care category had cycled through multiple “Amazon experts” without results. The brand was stuck on Vendor Central watching margins compress quarter over quarter. Unauthorized resellers were splitting the Buy Box and eroding pricing discipline. The catalog was thin, the storefront generic, and reviews were mostly imported from off-Amazon. The numbers were going the wrong direction.
The diagnosis
The account itself wasn’t the bottleneck. The distribution model was. As long as Amazon controlled pricing through Vendor Central, and unauthorized 3P sellers controlled the Buy Box for half the catalog, no amount of ad spend or content optimization would compound. We had to migrate the channel before we could fix the rest.
The 16-week migration playbook
Pre-migration audit (Weeks 0–2): We reconciled the brand’s top SKUs against Vendor Central historical data, the internal SKU master, and live Amazon listings. We found a meaningful share of the physical inventory was recoverable; the rest was lost to Vendor Central shrink and damage. We mapped every ASIN to a migration risk score.
Account standup (Weeks 2–4): Submitted Brand Registry application against the new Seller Central account. Configured tax, payments, and FBA settings. Closed all open Vendor Central purchase orders. The Brand Registry decision came in within the expected 5–14-day window, we ran it in parallel with everything else so it wasn’t a blocker.
Catalog migration and rebuild (Weeks 4–10): Migrated listings via flat file to maintain attribute consistency. Then rebuilt the catalog: new A+ Content, new product imagery shot in our studio, updated brand store, restructured variation themes for Subscribe & Save buyers. The pre-migration listings had been generic; the rebuild was operator-grade.
Listing relaunch and ad rebuild (Weeks 10–14): Coordinated FBA inbound so units landed before listings went live. Resumed Sponsored Products with conservative bids while the algorithm re-established CTR baseline. Layered Sponsored Brands and DSP after week 6.
Reseller takedowns (ongoing from Week 4): Test-buy paper trails, brand registry IP claims, MAP enforcement, cease-and-desist letters with documentation. Cleared the unauthorized 3P sellers splitting the Buy Box.
The result
4.8x revenue growth in 10 months. 30%+ storefront conversion. Margin improved 8 percentage points. The vendor agreement was closed. Unauthorized resellers, gone. The brand now controls its pricing, its promotional calendar, its customer relationship, and its margin trajectory.
What worked
Migrating at parity first, then improving, not trying to do both at once. Sunday relaunch timing for the new listings to minimize support contention. Reseller enforcement as a continuous program, not a one-time event. Subscribe & Save buyer behavior driving the catalog architecture. This case is a textbook example of why account management alone wasn’t enough, the distribution model was the actual constraint.
Why the numbers compound
In personal-care CPG, the Subscribe & Save flywheel is the LTV engine. Once a buyer subscribes, they typically renew 4+ times, meaning first-purchase ACOS that looks ugly on day one pays back inside 90 days. We restructured the catalog and ad plan around subscribe propensity, not first-touch conversion. The 4.8x revenue lift wasn’t a single hero quarter, it was monthly compounding once Subscribe & Save subscribers started stacking.
What we’d do differently
Move faster on the pre-migration audit. Two weeks felt like enough; in retrospect a third week of inventory reconciliation would have surfaced two SKU-level mismatches that we caught on relaunch instead of pre-launch. The dip in week 4 was small (under 10% of run-rate), but it was avoidable. Every migration we’ve run since has used a 3-week pre-flight.
