Invoice Envelope Details

The BillFin invoice is formatted to fit a #9 two-window envelope. Unforuntately, there doesn't really seem to be a "standard" for envelopes, however, as there are different versions of #9 two-window envelopes. The two windows should be aligned on the left about a half inch indented from the left edge. The top window a little shorter than the bottom as seen in the image below. 

If you want to use the envelopes you have now, you could also export the invoices to Excel and simply adjust the cell for the address to the right as far as you want. You could probably setup a macro to do this for all the Excel invoices. BillFin does not have a way to adjust the size or placement of addresses in the app currently.
