I need to categorize my already entered sale on base of project automatically instead of one by one transaction manually update.

The feature to automatically categorize existing sales transactions by project is not available in QuickBooks Online (QBO), Waleed6. To assist you further, I would like to share some details about how sales are managed in QBO.

 If you're looking to automatically categorize transactions that have been downloaded from your bank instead of manually entering them, you can utilize Bank Rules in QuickBooks.

Here's a quick guide on how to do it:

1. Go to Settings and select Rules.
2. Select New rule.
3. Enter a name in the What do you want to call this rule?
4. From the Apply this to transactions that are ▼ dropdown, select Money in or Money out.
5. From the ▼ drop-down menu, select a Bank account, or select All bank accounts.
   
    
   

    

6. Set the rule conditions. You can set a single rule with up to 5 conditions. Set and include the following, then select + Add a condition.
7. In the Conditions fields, specify whether the rule applies to Description, Bank text, or Amount. Then select Contains, doesn't contain, or is exactly to decide how QuickBooks applies the rules.
8. Select Transaction type, Category, Payee, Tax, Customer, and Tags to apply.
9. Once done, Click Save.

For more detailed information on how to set up bank rules in QBO, you may check out this article: Set up bank rules to categories online banking transactions in QuickBooks Online.

This feature allows you to set up rules that automatically assign categories to transactions based on specific criteria such as the customer name, transaction, description, or amount. By doing this, you can automate the categorization process for new sales data as it is entered into your system.

Moreover, if you are referring to manually entered transactions that need to be updated, you will need to do this process manually. However, if you're looking for a more automated solution for managing large volumes of transactions, I highly recommend exploring third-party apps or services that can integrate with QuickBooks. These apps may offer more advanced automation capabilities that can streamline your workflow.
