For the invoices list, I want to add bulk payments for all invoices instead of going into each invoice and pay it.

The idea of applying bulk payments to multiple invoices is a great suggestion, Octagon. I acknowledge how this feature would save you time by automatically balancing invoices with payments.

While this functionality isn't currently available in QuickBooks, I encourage you to submit a feature request to our product engineers for review.

Here's how you can do it:

1. Go to the Gear icon and select Feedback. 
2. Enter your ideas in the box provided, then hit Next.

For now, you can simplify the process by using the Receive Payment feature, then tick all the invoices you want to pay. This method reduces the number of entries you have to make compared to paying each invoice separately.

Please see the attached screenshot for visual reference.
 

If you want to take it a step further, consider exploring third-party apps with bulk payment features that integrate seamlessly with QuickBooks.

If you've linked your bank or uploaded transactions and want to match a lump sum payment to multiple invoices, you can use the Find Other Matches option. The system will create corresponding payment entries for each invoice, ensuring all of them are balanced.

Also, you can run the Transaction List by Customer report to gain an overview of total invoices, payments, and outstanding balances for each customer.

Here's how to pull this up:

1. Head to the Reports menu, then navigate to the Sales and customers section.
2. Select the Transaction List by Customer report, then click Columns.
3. In the Reorder area, tick Open balance.
4. Click Filter, then +Add another filter.
5. In the Select One area, pick Transaction Type and set it to Equals.
6. Choose both Invoice and Payment.
