Customer entity field that represents the sum total of all payment on the customer that has not been allocated to any invoices via a payment note. Available funds will be consumed prior to automatically re-collecting money on a customer’s payment method.
For the customer show below, all of their invoices have been paid. They make a payment for $15 and because they do not have invoices to allocate the payment to, the customer now has $15 of Available Funds.
We then invoice the customer for $18.00. When the invoice becomes due we automatically pull from the customers Available Funds.
Because the invoice has still not been paid in full we can see a Balance Owing of $3.00.
