The best thing I like about lokad is its easy to use interface, it has various features which help us in our work of managing inventories effectively as well as efficiently by having different views for each product category so that we can manage easily all products at one place.
In terms of cost management this was an excellent tool because now everything gets tracked from purchase order right down till invoices are generated automatically without any manual intervention needed. This had helped me reduce wastage significantly within my organization as there were no errors or mistakes made when submitting PO's & Invoice generation.
