I designed a web based stock take system for a client which incorporates time reducing practices.
The system was built to force users to work according to an efficient procedure – and allows the Warehouse Manager to view the progress through-out. At any point he/she can see the areas counted (vs un-counted) and the effect on the whole (System Stock Valuation vs Counted Valuation).
We improved the system bi-annually for the last 9 years.
Let me know if you need something similar!
