There are two ways to add a legal agreement / disclaimer / rental agreement / liability clause to an invoice:
1. Add the clauses by going to Settings -> Policy -> Default Invoice Template -> Message on Invoice. This only applies to the default templates in the system.
2. Go to More -> Order Printouts -> New Order Printout Template (and then select the appropriate option). Edit the subsection called ‘Details after line items’. Remove all the entries within this and then click the ‘…’ sign. Choose the Single Column option.
Then click the +Add sign and select the Free Text. Once done, click ‘Free text’ and enter the clauses in the ‘Customize Field’ Overlay.
