Record an offline AR payment received from a customer.
An offline payment is a payment that you receive outside the BILL system. BILL simply applies the recorded payment amount to one or more invoices for the customer. Any recorded unapplied amount is an overpayment and is available as a customer credit in the BILL system.
See Recording an AR payment in the Guides section for more information, sample requests, and responses.
