Epicor recently announced the availability of XLConnect for Epicor Multi-tenant hosted customers. XLConnect allows you to build your financial reports in Epicor ERP using your existing Excel Knowledge.
It embeds itself into Excel and then pulls your live data in as needed. It saves significant amounts of time compared to static data exports and manipulation and insures the data is accurate and that no GL accounts have been missed.
We have a demonstration of it here http://www.erp-demos.net/2011/06/epicor-xl-connect/
This advancement means the Epicor SaaS customers can now have the same great financial report writer option that is available to on-premise and our Azure hosted clients.
