It would be great if a project manager could raise a project billing line by entering a project percentage complete. The system would then a) multiply this Percentage by the Contract Line value, then b) subtract the previously invoice amount, this would result in the amount that is to be billed.
We need this and many other project based organisations need this method of creating project billing lines.

Thank you.

Excellent feature suggestion. Will take up for consideration in the next release wave planning. Please do solicit more votes as well.
