The bulk/mass invoicing feature allows you to generate multiple invoices at once for any given month. It can be found on your Run Dates tab on your Billing page.
Here's how to generate your monthly invoices:
Go to Billing > Run Dates.
Hit the blue "Bulk Invoice" on the right-hand side of the page.
From the pop-up menu, select the month you'd like to generate invoices for and select the issued date.
4. The pop-up will display information on the invoices that have been generated.
5. You can then navigate to your Invoices tab to view the invoices and take any next steps.
