Hey, @zoilagldsys22. 

Thanks for chiming in on this thread. Let me share some details to help answer your question about turning off automatic invoice reminders. 

If you turn off the option, I recommend creating and manually sending the invoice by clicking "Save and Send." This option will appear in the bottom right when making an invoice. 

Review this guide for more information about emailing invoices. 

This should do the trick. If you have any other questions, don't hesitate to ask. Have a great day!
