i think many have come to this type of error and managed but i wonder if this example was the same and the fix is already on V11 and V12.
The cost of the item is 283.50 with 3 Qty resulting in 850.50
Grand total 850.50 and rounding adjustment 0.50 in which results in 851.00
But when Submit the below error is shown
"Debit and Credit not equal for Sales Invoice #FAU-19/00035. Difference is 0.5.
Temporary solution was/is to change the rate already to 284 but there are case where the value has be rounded to less like 283 (a loss for the owner).
Below the screenshots
