Terms of service
CartonFit is a comparison and estimation tool, not a freight forwarder. Nothing on this site is a quote. The numbers are yours to verify before a decision that moves money.
CartonFit is a comparison and estimation tool for planning your own shipments. It prices shipments using rates you enter or public list prices clearly labeled as such, and it applies published carrier and marketplace rules. It is not a freight forwarder, it does not sell transportation, and nothing on this site is a quote, an offer, or a contract of carriage.
You may use the workbench and calculators free of charge for your own business planning. You may not resell or rebrand the tool itself, scrape or republish it as a service, or use it in a way that degrades it for other visitors.
Output depends entirely on what you put in, and bundled list prices go stale. Before any decision that moves money, confirm rates, scopes and rules with your own forwarder and with the marketplace's current published pages. The tier table and rate presets carry the dates they were last verified against published sources; treat anything older than your shipping date as history, not fact.
The service is provided "as is", without warranty of any kind, express or implied, including fitness for a particular purpose. To the maximum extent permitted by law, the CartonFit operator is not liable for any loss arising from use of the tool, including lost profits, mispriced shipments, or fees assessed by third parties. You remain responsible for your own purchasing, packing and shipping decisions.
Amazon and FBA are trademarks of Amazon.com, Inc. or its affiliates. CartonFit is an independent tool and is not affiliated with, endorsed by, or sponsored by Amazon or any carrier.
If and when a paid tier launches, subscriptions are billed by Paddle (Paddle.com) as Merchant of Record, and Paddle's checkout terms apply to the payment. The free calculators remain free.
These terms may be updated; the current version lives on this page. Questions: [email protected].
