Hi Susan:

Receivables doesn't keep a history of changes to the Customer profile. However I can think of 2 possible approaches.

1) Unzip/Restore a copy of your older data to a different folder and use GV to export Customers. You might need to look at several datasets to get a full picture.

2) Use GV to export Order headers from OE and look at the Terms that were used at that time.

Both approaches require some Excel manipulation to compare current "Net21" customers to what they used to be (likely using VLookup).
