Usually I have no need for any more than three invoices per month, however, occasionally (maybe once a year), I need two or three extra ones within the same month. I was thinking that it would be great if there was an option to purchase additional invoices on an ad hoc basis. I can’t warrant stepping up to a professional plan for the sake of three additional invoices in 12 months, so this may be an affordable solution?
You can create an invoice and when ready click preview then export. That will allow you to email it separately. The in the next month change it from draft to paid with the correct date. (My work around)
