No. Simply click the "plus" button and "Send a Quick Invoice."
We've created an invoicing feature that does not require an association with a Job.
Simply use the Quick Invoice button after clicking the "plus" icon at the bottom of the screen. Add a customer name, email address, then select a service or material and click Save to generate a Quick Invoice.
Note: an email address is required, as it is the only way to send an invoice to a customer.
