Amazon Seller Success Story: How Eagle Lights Switched Partners and Grew
Eagle Lights had already tried working with a third-party Amazon seller. It didn't go well. Reporting was inconsistent. Communication lagged. Pricing issues created friction. The Connecticut-based LED headlight manufacturer needed a partner who would manage the account like an operator, not a middleman.
In November 2019, Eagle Lights handed a small test assortment to SupplyKick. Within a month, the assortment tripled. Sales outperformed forecast by 20%. Ad sales grew over 100%. The difference wasn't strategy. It was execution, reporting, and trust.

Why Eagle Lights Left Its Previous Third-Party Seller
Reporting and Communication Issues
The previous partner didn't provide consistent sales reporting or clear account updates. Eagle Lights couldn't see what was happening in the account, which listings were moving, or where ad spend was going. Communication was slow. Questions sat unanswered. When visibility breaks down, trust follows.
Pricing and Account-Management Concerns
Pricing decisions created conflict. The seller's incentives didn't align with Eagle Lights' margin goals or brand positioning. Eagle Lights needed a partner who would advocate for the brand, not just push volume. They started looking for an Amazon partner who could take day-to-day management off their plate and report like a real account owner.
What SupplyKick Changed First
Eagle Lights didn't hand over the full catalog immediately. They started with a few ASINs to test the relationship. SupplyKick focused on the basics: clean reporting cadence, listing cleanup, and responsive account management.
Listing Content and Keyword Updates
SupplyKick rewrote product titles, bullet points, and descriptions with search-relevant language that matched how buyers look for LED headlights and aftermarket lighting. The content answered fitment questions, spelled out technical specs, and gave buyers installation confidence.
Product Photography and A+ Content Rollout
SupplyKick's in-house photographer shot new product images. Clean backgrounds, clear angles, visible beam patterns, and installation context. Then the team built custom A+ Content for each listing. For a technical product like LED headlights, A+ Content does real work: comparison charts, fitment guides, durability callouts, and before/after visuals that show the product in use.
Amazon's own data says Basic A+ Content can lift sales by 8%, and Premium A+ Content can lift sales by 20%.
Dedicated Account Management and Reporting Cadence
Monthly sales reports. Clear ownership of action items. Fast response times. The account manager kept Eagle Lights informed, listened to their input, and treated the account like internal inventory. That's what separated this partnership from the last one.
Within a month, Eagle Lights expanded the assortment. The test proved the relationship worked.
How Amazon Advertising Supported Growth
Ad Management Handoff
Eagle Lights wanted to focus on product development and new channels, not daily Amazon ad management. SupplyKick took over campaign oversight, search term refinement, and bid adjustments. The team invested its own capital into ad spend for Eagle Lights, which aligned incentives and removed friction around budget approvals.
Efficiency and Sales-Growth Focus
Ad sales grew over 100%, but the goal wasn't just spend more and sell more. The advertising team continuously refined campaigns to improve efficiency and return. That meant cutting wasted spend, focusing on search terms that converted, and balancing branded coverage with category expansion.
Results After the Transition
Sales Versus Forecast
Sales came in 20% above the forecast SupplyKick and Eagle Lights built together. That's not a projection miss. It's proof the account responded to better management.
Assortment Growth and Operational Momentum
The product assortment tripled quarter over quarter. Eagle Lights kept adding SKUs because the partnership was working. More products, better listings, stronger advertising support, and clearer reporting created a flywheel.
"We were apprehensive about working with another Amazon partner. However, our dedicated account manager kept us informed and listened to all of our suggestions. This made it very easy to do business with SupplyKick."
Keith Remy, Chief Technical Officer at Eagle Lights
That quote captures the core issue. Eagle Lights didn't need a flashy strategy. They needed an operator who would communicate, report, and execute without friction.
Lessons for Brands Considering an Amazon Partner Switch
Warning Signs to Look For
- No clear monthly reporting or account visibility
- Slow communication or questions that go unanswered for days
- Pricing decisions that create conflict or margin pressure without justification
- Incentives that don't align with your brand positioning or growth goals
Those aren't reasons to wait and hope things improve. They're reasons to start evaluating alternatives.
What to Expect From a Strong Amazon Operator
- Monthly sales summaries with clear action logs
- Fast, responsive communication
- Listing optimization, A+ Content builds, and photography
- Search term management and advertising oversight
- You should never wonder what's happening in your account
Start with a test. Hand over a small assortment, set clear expectations, and measure how fast the new partner moves. If reporting is clean, communication is responsive, and early execution delivers, expand the relationship. If not, you know within 30 days.
FAQ
What should an Amazon seller case study include?
Real proof: specific metrics, clear time windows, and named outcomes. A strong case study shows the starting point, what changed, who did the work, and what happened as a result. Vague language and generic claims don't build credibility.
How do you know when it's time to replace a third-party Amazon seller?
When visibility breaks down. If you can't get clear reporting, communication lags, or pricing decisions don't make sense, the relationship isn't working. Waiting rarely fixes structural issues. Test a new partner with a small assortment and compare the experience.
Which Amazon levers usually move first after a partner transition?
Reporting and communication improve immediately if the new partner is set up correctly. Listing updates, photography, and A+ Content follow within weeks. Advertising results take longer because campaigns need search term data, bid adjustments, and time to stabilize. Assortment expansion happens when trust is established and early results prove the relationship works.
Does A+ Content improve Amazon conversion?
Yes. Amazon's own guidance says Basic A+ Content can lift sales by up to 8%, and Premium A+ Content can lift sales by up to 20%. For technical products like LED headlights, A+ Content helps buyers compare specs, verify fitment, and see the product in use before they buy.
What does an Amazon agency usually manage after onboarding?
Listing optimization (titles, bullets, descriptions, backend keywords), product photography, A+ Content and Brand Story builds, Amazon advertising (Sponsored Products, Sponsored Brands, Sponsored Display), inventory coordination, pricing strategy, promotional planning, competitor monitoring, and monthly reporting. The scope depends on what the brand wants to hand off and what the agency can execute well.
