Also if you decide to round up or down instead of "to the nearest", you will have same problem (for example with a rounding down, try with a quantity of 2 on line 2 and you will have same differences between method 1 and 2). Difference will just appears with different data but will still occurs, so problem is not on how we make rounding but when. | Also if you decide to round up or down instead of "to the nearest", you will have same problem (for example with a rounding down, try with a quantity of 2 on line 2 and you will have same differences between method 1 and 2).

Second thing we can note is that if we use method 2, we must not show the column I, otherwise to total you | Second thing we can note is that if we use method 2, we must not show the column I onto invoice, otherwise to total you show on your invoice (2.73) will not be same that total you get summing total of each line (1.36+1.36=2.72). Showing column H might be better but total will still differs because total is rounded and result of summing column H lines will still differs. | ||
