There's no direct integration with Xero, but you can export a trial balance from Xero as an Excel file and import this Excel file to Accounts Production Advanced.
Accounts Production Advanced has an Import wizard to guide you through the import process, and you can save your import settings to speed up the process for future imports.
Follow the steps in our article: Import trial balance data in an Excel or CSV file to Accounts Production Advanced. From this article you can download our Xero to Digita mapping file. This will save you spending time manually mapping data for the import.
