Your receipts are not lost. So, you have nothing to worry about. For easy management of receipts on the app and performance considerations, we only show the most recent 50 receipts. All the receipts are either present in the app’s database or the cloud (if synced) and can be accessed when needed.
While you have only 50 receipts to see in the “Receipts” view, all of the “Reports” (Analytics) provide a consolidated and comprehensive view of all of your sales/ receipts.
