When you raise an Invoice against Work In Progress, profits or losses may be realised.
For example, suppose that you raise an invoice for €500 against tagged time of €400. You are offered a profit of €100.
If you accept this, it is deemed to be a 'realised profit', and will be included in the Profit and Loss Report.
If you have the relevant rights, the realised profit can be amended to another amount - say, €25. Only the realised profit of €25 is included in the report. The balance of €75 is deemed to be an unrealised profit amount.
