If you are using the Place Orders screen with more than one supplier selected at a time, such as can be common when ordering commodities available from multiple sources, StockIQ will display a "Supplier Totals" tab.
This tab will show relevant totals for all of your suppliers as you add/remove/edit quantities from each supplier, so that you can track where you are in terms of total spend, supplier minimums, or otherwise.
NOTE: If you are doing multi-supplier ordering and want to see each item available from each supplier without automatic filtering, make sure that you have un-checked the default Supplier Level = 1 filter in Step 1 of place orders, and you also want to set the multi-supplier item conflict option to "Allow All" in the Place Orders Display Options
