how can eReceipts be sent through to Xero?

Thanks for reaching out @kurtoeler! At this time, Expensify doesn't export eReceipts to Xero. However I do recommend sharing this in our Ideas section, as this is a great way for other customers to vote on your idea, and share their tips or tricks. Popular posts have a great chance of being added to our roadmap for future updates!

As for passing information to Xero, the only way to really do this would be to add that information in the description field on the individual expense. You could put something like "eReceipt on Expense" and that information will be exported to Xero. 

Thanks again for taking the time to post!
