To set the custom terms and conditions go to:
Settings > General Settings
Then go to the Terms and Conditions Tab. Check "Enable" next to the quote and invoice terms and conditioins.
You can then type in the custom terms and conditions you want to appear.
To view the custom terms and conditions print a quote or invoice.
You will see the terms and conditions appear at the bottom of the respective reports
