I had a bunch of auctions close on eBay on a friday, generated invoices, sent them, then on Saturday another bunch, ditto, Sunday some more. A few of the repeat winners I recognized by user IDs &/or emails but lacking a photographic memory I missed several. The only way I could figure to find my way out of this was to have grid view show all invoices except those that were closed or buyer not contacted, then one by one select an invoice / go up to the top / select invoice / merge invoice and then see if there were any other invoices associated with it in the window that appears, Is there an easier (less time consuming) way to acheive this? Another software I used to use assigned a buyer ID# to each unique buyer, so when a batch of auctions closed if a buyers ID# was out of sequence you would know it was a repeat buyer, it was handy, especially when dealing with a large number of auctions. I guess my question is how do others handle merging invoices?
