FreightMath, operated by Helix Platforms Ltd, provides planning calculators and shipper-prepared document templates.

Results are estimates. Freight class uses the public 2025 NMFC density scale and is not an NMFC item classification. Volumetric divisors are planning presets, not a carrier’s current service guide. Container and trailer sizes are typical internals. Pallet costs use only the rate you enter. Nothing on the site is a freight quote, a booking, a customs entry, or legal advice.

Paid PDFs are generated from the details you type and emailed after Stripe marks the payment successful. They are not carrier originals. A watermarked preview is not a shipping document. Pro and Pro Plus renew until you cancel in the Stripe billing portal. API access follows the plan limit for the calendar month and stops when the subscription is no longer active. Cancel at period end keeps access until that date.

Quote requests are optional. Sending one does not create a contract to move freight. Affiliate links, where shown, are advertisements for third-party services.

To the extent the law allows, liability is limited to the amount you paid for a document in the previous month.
