As answered by people managing https://open-gpt.app/ and TradeDocHub.shop.
TradeDocHub.shop's answer:
TradeDocHub combines all the calculators and document generators an import/export business needs into one free platform, instead of forcing users to piece together separate tools. Volumetric weight, CBM, landed cost, import duty, freight rate, and currency conversion sit alongside document generators for Bills of Lading, commercial invoices, and packing lists — all in one place, with no signup required to use the core tools.
TradeDocHub.shop's answer:
Most freight calculators online are single-purpose and scattered across different sites, or hidden behind paid software built for enterprise logistics teams. TradeDocHub is free, requires no account to use the tools, and covers the full workflow — from calculating shipping costs to generating the actual trade documents — in one session, without switching between five different websites.
TradeDocHub.shop's answer:
Small-to-medium importers, exporters, freight forwarders, customs brokers, and e-commerce sellers who source products internationally. These are people who need quick, accurate trade math and standard shipping documents regularly but don't have (or want to pay for) enterprise logistics software.
TradeDocHub.shop's answer:
I built TradeDocHub after seeing how much time small trade businesses waste jumping between different calculator sites and manually formatting shipping documents. I wanted one free, fast place to handle the everyday math and paperwork of international trade.
TradeDocHub.shop's answer:
HTML, CSS, and JavaScript (vanilla, no framework), served via Nginx.
TradeDocHub.shop's answer:
TradeDocHub recently launched and is used by individual importers, exporters, and small freight teams — we don't have named enterprise customers yet.
