One of GNomEx's helpful administrative features is the ability to automatically generate invoices for clients that have requested services. This action may only be performed by users with admin permissions in GNomEx.

To generate an invoice for a group or lab:

1. Click on the Manage billing button in the Administration section of the application home page or the Billing button from among the buttons at the top of the window.

The billing window will appear.

2. Select the billing period for which you are generating the invoice in the Period dropdown field.

3. Select the lab folder within the completed experiments part of the list that represents the lab or group for which you wish to generate an invoice.

4. Click on the Invoice button in the top left corner of the window.

An invoice will be generated in a separate browser window.

5. You can either email the invoice to the contact person for the account or print a copy of it by clicking on the appropriate hyperlink in the top right corner of the invoice page.
