We can add tags (as created) from a Shopify store along with the order as a line item and post the details in QuickBooks.

In Wevbgility, under Integrations> Accounting/POS> Posting settings> Orders - Under the Transactions tab you would find Display these order-related fields in the transaction

Click on the check box - Order tag as line item

Save and Continue the posting settings. Then post the order to Quickbooks.
