Invoice calculation

How invoice amounts are calculated from billed hours and rates.

This page explains how invoice amounts are calculated from billed hours and rates.

Invoice data sources

When an invoice is created, it automatically pulls data from two sources:

1. Timesheets: the time invested in the project by employees.
2. Expenses: the project-linked expenses logged by employees.

Billing cycle example

Consider an invoice created for the billing cycle 12 August to 16 September:

Although the baseline, forecast, and actual hours are within the billing cycle boundary, the value of the invoice is determined by the invoiced hours and expenses.

Expenses logged before the invoice was created are handled as follows:

• A: This expense belonged to the previous billing cycle, but since it had not yet been included in an invoice, it is pulled into this billing cycle’s invoice.
• C: Although this expense falls within the billing cycle, it is not ready to be included because it has not yet been approved by the project director or has been excluded for another reason.
• D and F: These expenses were logged and approved during the billing cycle and therefore form part of the invoice.

Expenses logged after the invoice was created are handled as follows:

• B, E, and G: These expenses will form part of a subsequent invoice.
