Prepaid Amortization Schedule: questions

What export should you use?

Use the QuickBooks Prepaid Expense Detail export, or the closest file that lists each prepaid item, vendor, amount, and term.

What happens to rows that do not match the rules?

Rows that do not match stay out of the output until they meet the rules, so you can review them and decide what to do next.

How do you change the schedule rules?

Edit the rules in plain words, for example the month spread, the columns you want to keep, or how to handle partial months, then run the workflow again.
