V8 - Adding a payment via an invoice

To apply a payment toward an invoice:

1. Go to Operations menu > Sales > Invoices.
2. Locate the appropriate invoice transaction on the Invoices list, then select Receive payment from the invoice record's Actions menu dropdown. This will generate a payment transaction from the invoice.
3. Select the payment method and edit other fields if needed.
4. Save the payment transaction.

Payment transactions against invoices will sync to QuickBooks Online and be linked to the corresponding invoice.
