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 in 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.
