Thanks for trying out QuickBooks Self-Employed, Robc2478.
QuickBooks Self-Employed is a proficient application that allows you to communicate with your customers real-time thus, it needs their email addresses when creating the invoices. This allows your customers to know what invoices you've made for them.
If your customers don't have email addresses, you can use your email instead.
That would be the workaround while the option to save without the email address is not yet available. Rest assured that this feature request will be forwarded to our developers. I will personally send feedback about it too.
