Recurring Invoices are a convenient way to automate the creation of Invoices or Draft Invoices.
Recurring transactions are automatically processed once a day at 04h00 UK time and will generate invoices based on the recurring invoice settings for your organisation.
CREATE RECURRING INVOICE
Navigate to the Sales tab and use the drop down arrow on the New Invoice button to select New Recurring Invoice. Proceed to enter the recurring invoice details as follows:

The remainder of the invoice should be filled out as per the normal Create Sales Invoice procedure. Click the Save button to complete the creation of the recurring invoice.
EDIT RECURRING INVOICE
Navigate to the Sales tab followed by the Recurring tab. A list of all recurring invoices will be displayed.

Click on the link in the Customer field to view or edit a recurring invoice. Any changes made will only affect invoices created on the Next Invoice date.
Recurring Invoices can be deleted at any stage to prevent further invoices being created. Alternatively, use the End Date to achieve the same result and still retain a record of the recurring entry in the list.
