Representative seller workflow
From inbound prep to reimbursement review, every step stays connected.
These are product workflows, not customer claims: they show the operational jobs MarginLock helps sellers complete when FBA shipments and settlement data start to sprawl.
- 01
Choose the SKUs that are ready to move
Inventory, reserved units, prep requirements, and inbound-plan status stay in one workspace before a carton is opened.
- 02
Pack cartons with compliance gates active
Weight, size tier, prep category, hazmat, and mixed-box rules are checked before labels print.
- 03
Create and ship the FBA plan
Amazon inbound milestones, placement decisions, labels, and shipment status are tracked as one operating loop.
- 04
Reconcile the money trail afterward
Settlements, fee drift, reimbursement candidates, and per-SKU contribution margin are reviewed from the same source of truth.
Packing-heavy sellers
Teams sending repeated inbound plans need box-content accuracy, carton weight visibility, and label readiness without rebuilding spreadsheet templates.
Margin-sensitive catalogs
Sellers with tight contribution margin need fee drift, settlement variance, returns, and reimbursement candidates visible before month-end review.
Owners with small teams
Operators can pack and ship from a clear workbench while owners still see the financial exception queue tied to the same shipment history.
