Hello, sales209. 

There are possible reasons why the import of goods is not shown in the 3B. Please take a look at the following scenario:

• To be compliant, QuickBooks requires the use of items listed in the Products and Services list, appropriately aligned with HSN, SAC codes in all transaction types involving sales and purchases, i.e. Invoice, Sales Receipt (Cash Memo), Bill, Expense, Cheque.
  • This means that you must use forms and not journal entries to enter your sales and purchase transactions which are subject to any GST rate including Exempt and Nil.
  • On purchase forms, you must enter purchase line items in the Item details section only. Account details should not be used. Transactions, especially on the purchases side, will not reflect in the GSTR 3B if the Account details section has been used to record them in QuickBooks.
  • The GSTR 3B in QuickBooks will now pull transactions that have been entered using Account details.
• All forms of the type Sales Receipt (Cash Memo) must have a Customer selected. The GSTR 3B will not pull Sales Receipt (Cash Memo) forms without a a Customer.
• All forms of the type Expense must have a Supplier selected. The GSTR 3B will not pull Expense forms saved without a Supplier.
