Is it possible to reclass multiple entries in QuickBooks? I like to reclassify multiple transactions in batch, not one at a time.

You can do batch reclass for expense transactions recorded to Account details tab. They use the account from the Chart of Accounts. These expenses are created using the Expense, Check or Bill in QBO

However, if it’s sales forms entries like customer invoices that use the product/service item code, then it’s not possible to do batch reclass from one account to another account. The same thing applies to purchases (like inventory purchase) that use Items details tab.

So, if your original entry is Journal Entry type or Sales form or Product/Service Item, you can’t do batch reclass. You can’t also batch reclass class/location in regular QBO.

To reclassify category in batch for account details entries:
From the homepage dashboard > Expenses > Expenses > Select transactions need to be reclassified to another account category > Select “Categorize selected” under Batch actions > Select NEW Category > Apply.
