Issue in total billing amount with commas and full stop

Hello there, @info1772.

I want to make sure you'll get the correct information about your concern. However, I still need to gather more details about it. Can you tell me more about the challenges you encountered when you try to raise a Proforma invoice in QuickBooks Online (QBO)?

This way, I can share with you the best resolution. You can also attach a screenshot (if necessary). Just make sure to cover the important details. 

Please go back here so I can help you with this matter. Take care and stay safe, info1772.
