Posting an invoice with manual collection will tell Recurly to issue the invoice, but not attempt any payment. You can manually enter an external payment later, or have the customer pay the invoice with an automatic method via our Make a Payment button on the hosted invoice.
Note that once an invoice is paid, or attempted to be paid, with the billing information on the account, the invoice converts to automatic collection. At this time it is not possible to record a manual payment on an automatic charge invoice or convert a charge invoice from automatic to manual collection.
To manually record an external payment, view the invoice in the Admin Console and enter the payment details in the left sidebar. A manually paid invoice can be reopened.
