I am close to my fiscal year-end and I need an invoice quickly for my recent content purchase.

Content invoices are generally posted in Marketplace within 2-4 business days following the order, but are always dated the day the order was placed. Invoices are generated overnight and therefore cannot be issued the day of the order. If you have an urgent invoice request, contact our Accounting team via the Invoicing web form located on the Support tab in OverDrive Marketplace noting the specific date by which you need your invoice.
