What do I do with opening balances for customers and suppliers?Will a Journal entry do?

It's good to see you posting your concern here in the QuickBooks Community, @sandra-ppg-ie.

I'm here to help you ensure you can manage your customers and supplier's opening balances in QuickBooks Online.

It's recommended to leave the opening balance blank if you have suppliers and customers with open balances prior to the date you opened your QuickBooks Online account. Rather, enter your supplier's or customer's outstanding invoices or your supplier's unpaid bills into QuickBooks. This enables you to include precise details about what your customers are paying for and what you're paying your suppliers for.

Once you're ready, choose whether you'll want to add a customer or supplier. Here's how:

1. When adding a new customer, leave the Opening balance blank.
2. Click Save.
3. Then, create any unpaid invoices for the customer by going to Customers & leads, and then select Customers.
4. Choose the customer.
5. From the New transaction ▼ dropdown, select Invoice.
6. Then, create a new unpaid invoice for the customer.
7. Ensure the Invoice date is the actual date you provided the products or services.
8. Repeat for any other unpaid invoices for this customer.

It's important to only add unpaid invoices. Don't add any transactions for this customer that were paid and closed before you started using QuickBooks.

To add unpaid bills for a new supplier, you can read this handy article: Manage outstanding balances for customers and suppliers in QuickBooks Online. It includes a detailed process if you already entered the opening balance instead of leaving it blank.
