Returning multiple values in multiple cells based upon one input

I need to develop a worksheet that automatically populates all invoices for a specific customer based upon the customer number I enter. I want each individual invoice number to populate in a separate cell. I uploaded a file with three tabs. The first tab is the data I am working with (sorted by customer number). The second tab is the statement showing how I want the final result to look (I just copied in the information that I want to see for one particular customer), and the third tab shows the same statement format, but without the end result so that the appropriate formula(s) can be entered to populate the information. I am using Excel 2010.

I've reviewed other threads, but none seem to get at what I'm trying to do w/o using VB. Any help on this is appreciated.

This is very helpful to populate columns C D & E (document date, amount and net due date) once the invoice number in column B is populated. Do you have any suggestions for formulas to add to column B to automatically populate all invoice numbers once the customer number in cell C4 is populated? The example file I attached doesn't show multiple customer numbers in the drop down box, but in my actual file, there are multiple customer numbers that I can choose from. When I change the customer number, I want a list of invoice to automatically populate instead of copying and pasting the list of invoice numbers. Any thoughts?

Thanks again.
