***NOTES FROM CURATOR***
This is a simple and very effective app with a great user interface and robust notifications and approval chain process already setup. It could easily be expanded to handle creation of invoices and purchase orders to manage the entire PO process and also could then be linked with financial apps such as QuickBooks.
