The dreaded rounding problem regarding dollars and cents.

Hello, I am new to this Forum and am desperate. I have a billing spreadsheet where one invoice has the potential of being paid for by up to 6 clients. The amount of each client's invoice is calculated via formula for their assigned percentage responsibility. I find when adding each clients calculated invoice totals, sometimes they total a few cents more than the actual total of the original invoice (clear as mud). See my attached spreadsheet as an example. I populate the Invoice Total column with the total amount found on the invoice generated from my billing program and let the formulas in the spreadsheet calculate each client's assigned responsibility. I have highlighted in yellow an example of a variance. Any suggestion is appreciated.
