Can someone help please? why when I switch on Progress Invoicing Create multiple partial invoices from a single estimate and save it. It just jumps back to off.

Progress invoicing is an important feature in QBO, and I understand you would like to utilize it when billing your clients. Please allow me to provide relevant details and address any questions you have regarding this capability, Sandra. 

Currently, the new invoice experience does not support progress invoicing. This is why it automatically jumps off when attempting to use it.

We want to inform you that our product engineers are still working to make all classic features supported in the new layout. 

While there may be temporary gaps in the available features, we are actively working towards creating faster and more powerful forms that better cater to your needs.

You can read more details about the updates here: 

• See What’s New With Estimates and Invoices in QuickBooks Online
• QuickBooks Invoices and Estimates FAQs

For the time being, you have the option to generate a separate invoice for the amounts you are currently charging the customer.

Thank you for your understanding and patience during this transitional phase, Sandra. Please feel free to reach out if you have any further questions or need assistance with invoicing and sales transactions. I am here to help you.
