Ordering module for retail in Australia

Hi forum

we are an Australian multi channel, multi site retailer with 40 store implementing netsuite as our ERP

I'm looking to find out if anyone knows of an ordering suitelet in Australia which will handle
-Ordering to multiple locations,  both based on demand generated by netsuite AND manually entering quantities
-Ordering to a single warehouse location and managing transfers from a single warehouse to multiple locations
-Handling the ordering across 3-4 thousand SKUS, across around 150 suppliers

Order items in netsuite does not allow us the flexibility we need and looking for any advice anyone has had or experience with plug in type applications which offer much more flexibility in the way in which ordering is done - especially with manual ordering.  Our business is highly reactive, and driven by seasonal and pricing factors which algorithms and rules can not predict.  Hence why fast manual ordering across multiple locations, across multiple SKU's  is a critical part of our retail business.
