Yes, you can.
If you have one or more businesses, you can use just one 1tap account and differentiate between these expenses using tags and notes. So you can tag an expense as Business A, Business B or anything else you'd like or you can also add a note with details about the expense.
The tags and notes you've added will be visible in separate columns in your exported expense reports, making it easier for you to sort and organize this data however you might need in an Excel spreadsheet.
And here you can see how to export the data submitted to 1tap.
