An Organisation's Administrator can provide a message that will be shown to Requesters during Bill creation.
This is how instructions for Bill Requesters can be set up:
Select your Organisation in the main menu and open "Approval workflows" page under "Workflows and settings" section.
Click on the Bill workflow.
Click on the gear icon
and scroll down:
Type in the message that will be shown to Requesters when they create a new Bill.
If you don't want Requesters to see any instructions, then leave this field blank.
When you finish, save your settings by clicking on the "SAVE" button in the right upper corner of the workflow settings and Update/Activate workflow.
