Our loading crew already does a good job loading trucks. Why do we need load planning software?

Will your loading crew be able to tell from looking at 10,000-item shipping invoice with 100 different categories of cargo, how much and what type of trucks to request for optimal cargo loading? What if cargo will need to be partially unloaded and additional cargo later added? What about axle wait distribution, cargo fragility, stacking, maximum forklift loads, loading optimization based on the value of goods, in case of surplus, and so forth, and so on? And all that at the same time?
Packer3d will do all that.
