Product
One platform. Three pillars.
MarginLock combines warehouse operations, financial reconciliation, and Amazon compliance enforcement into a single tool. Built so a small team can run a serious FBA operation.
Warehouse
Inbound, prep, pack, label — without spreadsheets.
Plan shipments by SKU. Auto-pack into the right cartons. Generate compliant labels. Resolve box weight and dim issues before they become reboxing.
Financial
Reconcile every dollar Amazon pays — or doesn't.
Tie every settlement line back to its source order, return, or fee. Detect overcharges. Automate reimbursements. Track per-SKU contribution margin in real time.
Compliance
Stay ahead of penalty fees.
Box weight gates, hazmat prep gates, dim-tier validation, IPI-aware planning. Catch the violations that trigger fees before a label prints.
Product map
Each pillar is deep enough to stand alone, but stronger together.
Warehouse workbench
Inventory upload, prep tasks, carton packing, label readiness, and shipment milestones for FBA inbound work.
Financial reconciliation
Settlement matching, fee detection, reimbursement queues, and per-SKU margin review after the shipment leaves.
Compliance controls
Overweight, mixed-category, hazmat, prep, and dimension checks before small mistakes become Amazon penalties.
