Is there any quickbooks report that is very close to the format needed to upload bill payments and their applications to vendor bills in NS? The closest I found is the Bills and Applied Payments report but I hope there’s a better one.

It’s one of our newly acquired subsidiaries. The owners wanted all transactions after the acquisition to be in NS. We were not able to use NS for that subsidiary immediately after the acquisition. Had to use QB in the meantime
