# Essential dunning
Orb provides essential dunning capabilities help you recover revenue from failed payments and overdue invoices in an automated way to scale your collections efforts.
If [auto collection](https://docs.withorb.com/invoicing/payments#auto-collection) is enabled and the invoice cannot be collected for the configured payment method, Orb will automatically retry the charge after 1, 4, and 9 days from the initial payment attempt. If the final attempt does not succeed, Orb sends a [payment failure email notice](https://docs.withorb.com/invoicing/invoice-delivery#email-types).
Orb also retries payments intelligently when they're most likely to succeed. If the linked customer at the payment gateway does not have a payment method set, Orb will not attempt to create a dunning schedule. However, any time a payment method is initially set, or updated upon exhaustion of a previous dunning schedule, Orb will immediately try to collect on the invoice.
### Getting started
In Settings > Invoices, ensure you have enabled Orb to send invoice emails, and retry failed payments.
