I have the same issue. Sometimes I make adjustments or changes to an invoice like adding or eliminating items or even just changing my category for internal purposes to better keep track of certain services, however, that does not mean I want my client to see each change, correction, or adjustment I make to an invoice. Those are internal accounting changes that the client does not need to know about. Sometimes I even start an invoice and keep adding items and services throughout the month and bill monthly at the beginning of the next month, why would I want my customer to see the invoice 10 or 15 times or more when they are not the final one? I want them to see the final one, not everything in between. I do not send the invoices directly from QBO, I print or download them to a PDF, save them on my computer and/or OneDrive and then send them using Outlook. I only use QBO for sending reminders when they are past due and even that, I do manually, I do not have the automatic reminders option ON. The fact that if my customer uses QBO, they will see every time I make a change to their invoice, whether I am ready to send it or not, is an issue for me. Even after sending the invoice, some of the changes I make have nothing to do with the amount or services provided but more as notes and clarifications for future reference that are not the customer's concern. None of the answers presented here give a solution to my issue, they don't even tell me if there is a way to prevent this from happening. Some of the answers mentioned that once sent, the customer will see all changes made to it after, but again, I do not send them through QBO and this still happens to me. If you were able to figure out how to prevent this, can you please share?
