When invoicing, pre-billing, or post-billing, the charge value of the transactions applied to the invoice will determine the value of the invoice. This can be affected by marking up or marking down the invoice value of the transactions.

How the invoice value is calculated can differ depending on whether the invoice stage has only timesheet transactions, only expense transactions, or both.


Markup (Invoice value > Charge value)

  • Timesheet values are marked up proportionally and expense values are maintained.

  • Where expenses are the only included transactions (i.e. no timesheets), they are marked up proportionally

No markup (Invoice value = Charge value)

  • All transactions maintain their value

Markdown (Invoice value < Charge value)

Timesheets and expenses

  • If the total expense charge value < invoice value, then timesheets are marked down proportionally and expense values are maintained

  • If the total expense charge value = invoice value, then all timesheets have an invoice value of zero, and expense values are maintained

  • If the total expense charge value > invoice value, then all timesheets all have an invoice value of zero, and expenses are marked down proportionally

Expenses only

  • Expenses will be marked down proportionally.

Note: These calculations are done for each invoice stage, so the transactions from one stage will not impact the calculation method of another stage.


When you have only timesheets or only expenses on an invoice stage, the invoice value of those transactions will be marked up or down proportionally.
