Easy setup and configuration by using excel file templates for each department/warehouse. It allows me to map existing PO's which i can easily add into my optimisation plan. As an ERP administrator having only 1 system is always difficult so this has helped ease that burden as well. Nothing in particular but all around good productOptimiser does its job with great customer support. I would recommend it if your looking for a quick solution or even long term. This software helps us manage our inventory, orders and shipping process very efficiently. I like that this software is easy enough for anyone in your organization can use with out any training or assistance from an expert user! This makes using such great value as well since most companies don't want their employees spending time learning new things when they could be working instead (or at least doing other valuable work). None really - everything works pretty much how we need without too many issues being encountered along our journey so far which has been very good thusfar!!
