The working is shown
Every result lists the steps and figures it used, so you can follow the calculation and spot a wrong input.
Honest about limits
Results are planning estimates. Real capacity also depends on columns, doors, fire exits, safety clearances, your equipment and your products.
Built from warehouse practice
The tools are built and checked by a warehouse supervisor with about 15 years of hands-on experience in warehouse operations, stock control and space planning. About WarehouseCalc
