Applying payments to multiple invoices
Navigate to Storage > Accounts and select an account.
First, click Add Payment in the Invoices, Credits, & Payments section.
Next, select the payment method. The Amount field will automatically populate with the total amount due across all unpaid and/or overdue invoices.
Then, click Next.
Next, enter the customer's payment information and click Make Payment.

Note: All unpaid and/or overdue invoices will be automatically selected. You can deselect or change the amounts as needed.
