The return policy is automatically printed on the bottom of all receipts.
To Create & Edit A Return Policy:
Click the Taxes & Policies tab
Type the return policy in to the Return Policy text field
NOTE: Your return policy can be as long or as short as you would like. Keep in mind that simpler return policies are typically the most effective and that all text will be printed on the bottom of your receipt, so you can save space and paper with shorter policies.
