Recurring invoices

For regular billing, such as a monthly fee, turn on the Recurring invoices module in Account, Modules/Features. Create the recurring document like a normal invoice (Recurring, New recurring invoice) and choose how often it should be issued (monthly, every second month, quarterly, half-yearly, yearly) and whether straight away as an invoice, or first as a proforma invoice.

The documents are then issued automatically. In the module settings you can choose to email issued documents to the customer right away.
