It is certainly convenient to have historical transactions in the file in case a question comes up, rather than having to search an archived record, scanned documents, or worse, paper records. When converting a company file from Xero to QuickBooks Online, the first thing to decide is whether the historical transactions will be part of the new file and if so, how far back to go with them. Whether or not it is the right thing to do is a discussion for another day. The only purpose of this article is to discuss the basics of doing the conversion. I have done many of these conversions, as I have also done in the opposite direction. I will make no attempt here to discuss the possible reasons for or against doing so. There are many reasons a company or its bookkeeper or tax preparer/accountant may want to convert a set of accounting books from the Xero platform to the QuickBooks Online (QBO) platform.
