To add the POS line items to a letter, first click on the Configuration tab
Then choose Letters and Templates.
You can either add a new letter or edit a letter already on your list. First, click on the Letter Codes drop-down, and choose Invoice POS Line Items. This will display this code in the letter.
Make sure and save all your changes in the top right of the letter page.
When you select the letter from your letter drop-down, it will display all the POS items with a date, description, price, and total.
