Setting up FBA prep while managing four 3PLs was a nightmare we didn’t know how to solve. Clearsight took the whole thing off our plate — now product moves from factory to Prime shelf without us touching it.
● What 4PL actually means
The operator layer between you and your logistics partners. We run it.
A 3PL stores and ships. A 4PL manages the 3PLs, coordinates replenishment across channels, and makes sure your supply chain doesn’t become the reason a campaign under-delivers. Most brands have 3PL relationships. Almost none have someone accountable for orchestrating them, watching the aged inventory, sequencing WFS vs FBA inbound, and syncing the fulfillment calendar with the media plan. That’s what we do.
Brands in our Full-Service and Enterprise tiers run their entire fulfillment operation through us. Factory-to-Prime-shelf without the brand touching it. One team. One P&L. No stockouts from a campaign your logistics partner didn’t know about.
● What we model
The FBA vs WFS breakeven, four variables most agencies get wrong.
● What we manage
Every layer of the fulfillment stack, coordinated.
In-stock monitoring, reorder triggers, and inbound shipment planning. We watch the aged-inventory clock so you’re not hit with surcharges on slow-movers.
We model the breakeven across your SKU mix and route inventory to the channel where the unit economics work. Not a set-it-and-forget-it split.
We act as the operator layer between you and your 3PL partners, SLA monitoring, chargeback disputes, inbound routing, and compliance management.
Real-time inventory insight across FBA, WFS, and our South Bend warehouse. The agency team pulls from this before setting campaign budgets and promotions.
Removal orders processed, graded, and rerouted, back into FBA, to our warehouse, or liquidated. We recover units before the aged-inventory meter runs to the catastrophic tier.
For brands adding Walmart WFS, Chewy, or a new marketplace. Carton requirements, item setup, inbound routing, and first 90-day inventory plan. Rolls into ongoing 4PL management.
● From the insights desk
Leaving FBA for FBM + 3PL, the 90-day plan that doesn’t break Buy Box.
FBA fees climbed enough in 2025–26 that 3PL-backed FBM is a genuine economic option for brands that wouldn’t have considered it three years ago. But most migrations that fail don’t fail on fee math, they fail because the Buy Box win-rate collapses in week two and doesn’t recover. We published the 90-day sequencing playbook we use when we lead a brand through it: what to move first, how to protect Buy Box during the transition, and when the math actually justifies the switch.
