Have you ever wondered why your listings in your inventory don’t match what you have on the listing services like Alibris, ABE Books, etc.? You know, they say ‘For Sale’, your inventory says ‘Sold’ or visa-versa. Well, here is a program which will take a file downloaded from your listing service and check it against what you have in inventory. It will indicate which books don’t have the same status (Sold versus For Sale) and which books are in your inventory program and not on the listing service (maybe a missed upload?).
