It would be great if the Page Title reflected more specific details about the page being viewed.
e.g. Instead of saying "Sale | Dear Inventory" it could be "LastName SO-Number" (Where LastName would be the customers last name and SO-Number would be the sale order number.)
The same could be done for Purchase Orders and Inventory Items.
This would help to identify which tab has the information you need when many tabs are open. (This would be particularly helpful when running with something like Firefox 'Tree Style Tabs' extension.
