Professional-grade logistics tools. Free, and built by someone who uses them.

Compare gross and volumetric weight under each mode’s convention — selectable and editable — and get an auditable chargeable weight: air, express, sea LCL (with W/M minimum) and road by density and by loading metres (LDM).

Calculate the reservation and limitation deadlines of a road transport claim under the CMR Convention (arts. 30 and 32): from the delivery date, with configurable non-working days, auditable math and calendar export of every deadline.

Fast conversions between the metric and imperial units that show up daily in quotations, packing lists and B/Ls: length, weight, volume and density.

Pick a rule and see who bears each cost — from packaging to final unloading — and where risk passes from seller to buyer. The four maritime rules (FAS, FOB, CFR, CIF) are flagged.

Enter the driving done so far and see how much time remains within every Regulation (EC) 561/2006 limit — mandatory break, daily, weekly and fortnightly caps — plus the daily rest due.

Enter your boxes or pallets and get a deterministic load plan: piece-by-piece placement, volume and weight utilization, centre of gravity per the CTU Code, VGM (SOLAS) and an orientative country weight-limit check. Everything is computed in your browser.

Every tool on this site can also be called over HTTP GET: same calculation engine, JSON response, no signup, no API key and nothing stored. Built for light integrations, spreadsheets and scripts.
