Question 1

Do I need an account to calculate?

Accepted Answer

No. You can run a calculation and see how many units fit without registering. A 3D arrangement, centre of gravity checks, compliance results and exports require an account, which is free and includes three full runs a month.

Question 2

Which container types can I plan?

Accepted Answer

20GP, 40GP, 40HQ and 45HQ dry containers. Inner and door dimensions can be overridden to match your container owner's specification sheet. Reefer and flat-rack support is in development.

Question 3

Does the calculator run in the browser?

Accepted Answer

Yes. The solver runs as a Web Worker on your machine, so the geometry never leaves your browser and the interface stays responsive during a calculation. Plans you choose to save are stored on our servers in Hong Kong.

Question 4

Can it model irregular frames and protruding guards?

Accepted Answer

Enter a conservative envelope covering the longest, widest and highest points, plus clearance. The solver never assumes a gap that does not exist, so a plan that fits on screen also clears the door and the walls.

Question 5

How do I stop a control cabinet being laid on its side?

Accepted Answer

Set a keep-upright flag on the SKU. Those orientations are removed from the search, and if the load only fits by tilting the item you get a named orientation-conflict warning instead of a silent compromise.

Question 6

Can one plan mix naked, crated and palletised cargo?

Accepted Answer

Yes. Packaging type is a per-SKU attribute with its own clearance, stack limit and fragile behaviour, so a mixed food line is planned as one load rather than three separate exercises.

Question 7

How is centre of gravity checked?

Accepted Answer

The plan calculates CG on all three axes from the weight and position of every placed item. It flags CG height above 40% of the internal height and any half-section carrying more than 60% of the total mass.

Question 8

Do you check axle loads?

Accepted Answer

Yes. Front and rear axle loads are estimated and compared with the container's configured range, typically 30 to 50% front and 50 to 70% rear, so an overweight axle is caught before the weighbridge does it for you.

Question 9

Is floor strength considered?

Accepted Answer

The plan compares each item's weight against the configured floor rating and reports bearing pressure for the footprint you enter. For concentrated loads, use spreader plates and confirm with the container owner; the tool is a planning aid, not a structural certificate.

Question 10

Can I import a whole packing list?

Accepted Answer

Yes. Download the Excel template, fill in dimensions, weight, quantity, packaging type and constraints, then upload. Invalid rows are reported by line number rather than silently dropped.

Question 11

How does the solver use the space above low items?

Accepted Answer

After placing the large items, it searches the remaining volume as free boxes rather than a flat floor. Pallets go on top of low frames and small cartons fill shoulder gaps, provided stack limits and bearing capacity allow it.

Question 12

Can I keep each shipper's cargo separate?

Accepted Answer

Yes. Assign a client group and each group gets its own colour in the 3D view, the placement table and the PDF, so a consolidation can be sorted at destination without unpacking the container.

Question 13

What formats can I export?

Accepted Answer

PDF with 3D views and the compliance checklist, and CSV for the packing list. Paid plans can export a white-label PDF with your own header and logo.

Question 14

How long does a share link last?

Accepted Answer

Thirty days by default. Shared plans are read-only, hide the editing controls, and carry a call to action so a recipient can run their own calculation.

Question 15

Where is my data stored and how do I delete it?

Accepted Answer

On servers in Hong Kong. You can delete an individual plan immediately, or your entire account from settings; account deletion removes plans, SKU libraries and profile data permanently. See the privacy policy for the full detail.

Question 16

What does annual billing mean in practice?

Accepted Answer

You pay ten months and receive twelve. The invoice is issued once, up front, and the effective monthly price is roughly 17% lower than paying month to month.

Question 17

Can I cancel without contacting support?

Accepted Answer

Yes. Settings, Billing, Cancel plan. Your access continues to the end of the paid period, then the account moves to the Free tier and your data stays readable for 90 days.

Question 18

Can I buy a single plan without subscribing?

Accepted Answer

Yes. A single container plan is $9, a white-label pack is $29 and an export compliance report is $29. No subscription, no minimum volume.
