eBay sends automated payment reminders to your buyers. We also understand that some sellers prefer the option to manually send invoices to their buyers as payment reminders.
As part of the ongoing work to reduce the number of unpaid items on eBay, we are evaluating these processes to ensure buyers are receiving appropriate and timely reminders. You may have noticed a recent change to the invoicing process. Based on your feedback, we are removing that recent change to invoicing so that Sellers can continue to send invoices as payment reminders. The automated payment reminders also will be sent at 24 & 48 hours after the listing ends.
