This issue still exists in version 1.4.10. Here’s a complete description of the problem & reason for it. Problem: Discrepancy in total amount between quote & invoice Exact steps to reproduce the problem
Create a valid quote with few products & few quote tax. Save it.
Now use the option Quote to Invoice to create an invoice.
Observe that the total amount in the quote & invoice. As an example see the screenshots attached.
Reason for problem: The discrepancy in the total amount is mainly because the quote taxes are not included in the calculation of total amount for invoice. Solution: Saving the invoice updates the invoice total. Now the invoice & quote total match each other. Refreshing the page does not solve the problem but saving the invoice does solve the problem. @Kovah the expected behaviour for a normal user will be to see the same total as in quote as soon as the invoice is generated.
