Hi, I recommend esProc or esCalc, they are desktop BI tools, powerful computing script and spreadsheet on data computing, analytics and reporting, quite easier to use than general tools, and the cost is quite appropriate too. But I'm not sure if they can help for sales forecasting.
Here are some cases for sales data analytics:
Statistics on Sales Values of the Top 3 Salespersons Distributed in Respective Product Categories
Top n Clients Accounting for Half of the Total Sales in This Year

Hope it can help you.
Hello,
Why not you can prefer Business Intelligence tool for your sales analysis, I offered you "Answergen''- Its a web-based business intelligence tool on cloud basis. Just you can try in trial version if you're like it you can upgrade it.
Why don't you try using Apptivo software i am using the same for my personal use. It is easy to use at a affordable cost.
