Hello northerngirl, 

Welcome back to the Community. I'll be happy to share more info about scheduling invoices so you can continue to do your work with peace of mind. 

Since the scheduled invoices didn't go out as expected due to the reason you've highlighted above, I recommend recreating the scheduled invoices again (with today's date) so they can get sent out to your clients. Here's a helpful article that shows you how to: Manage schedule transactions.
