Planner guide & frequently asked questions
From Excel packing list to a 3D load plan
For exporters, freight forwarders and warehouse teams checking a shipment before loading. Planning needs no account; free PDF and CSV export asks for an email. Product updates are optional.
1. Review your cargo
Import Excel or CSV, choose the worksheet and map your columns. Check units, accepted quantities and excluded rows before calculating. The CSV template uses cm and kg.
2. Calculate and inspect
Choose the container and set fragile, upright and stacking rules. Optimise, rotate the view and check unplaced cartons, payload and balance. A packing estimate is not a certified loading or securing plan.
3. Hand off the result
Export a PDF plan or CSV placement list, or share a snapshot for review. For pallet shipments, send the same carton list to pallet quoting using the action above.
Why do some cartons remain unplaced?
Available volume alone does not determine fit. Carton dimensions, door clearance, orientation, payload and stacking rules can limit the result. Review the highlighted constraints and recalculate after edits; the heuristic does not guarantee the mathematical optimum.
Which container dimensions should I use?
The 20ft GP, 40ft GP and 40ft HQ presets are planning assumptions. Confirm your actual equipment dimensions, door opening and permitted payload with the carrier before loading.
