{{ property.first }}: {{ property.last }}
{% endunless %} {% endfor %} ``` The `property.first[0] == '_'` check hides STOQ's internal tracking lines (their names start with an underscore) so only the customer-facing details print. STOQ adds these underscore-prefixed lines mainly when the offer uses **Use without purchase option**, where it stores tracking data such as the selling plan reference as a line-item property.

STOQ names each line after the detail, for example: > **The Complete Snowboard, Powder** · Qty 1 > Shipping: As soon as possible > Reserve now, pay later: Pay 0% now and the remaining will be charged when your product is shipped. > Preorder: Save 50%, ships on Shipping: As soon as possible ## Check your setup 1. **Turn on the details** 1. In the offer editor, expand **More settings** and click **Advanced**. 2. Under the **Cart** heading, turn on the details you want. 3. Click **Save changes** at the top right of the editor. 2. **Place a test preorder** On your storefront, add the preorder product to cart and check out. 3. **Check the order in Shopify admin** Open the order in Shopify admin and confirm the details appear under the line item (for example, "Shipping: As soon as possible"). 4. **Print or preview the packing slip** 1. From the order, click **More actions**. 2. Click **Print packing slip**. 3. Confirm the same lines appear on the slip.

Turning them on now won't add them to existing orders; turn them on and place a new test order to confirm. ### Details show in Shopify admin but not on the printed slip Your packing slip template isn't printing line-item details. Add the loop from "Print them on your packing slip" above. ### Lines starting with an underscore show up on the slip Your template's loop isn't filtering out STOQ's internal tracking properties. Use the `property.first[0] == '_'` check shown above. ### A visible line like "Shipping: As soon as possible" prints and you want to hide it Each detail you turned on prints as its own line, named after the detail (for example a **Shipping** line for the fulfillment timeline). To drop a specific one, add its name to the loop's filter. For example, to hide the shipping line: ```liquid {% for property in line_item.properties %} {% unless property.first == blank or property.first[0] == '_' or property.first == 'Shipping' %}{{ property.first }}: {{ property.last }}
{% endunless %} {% endfor %} ``` ## FAQ ### Does STOQ have its own packing slip template? No. STOQ adds preorder details to the order at checkout; printing is handled by Shopify's built-in packing slip feature or an app like Order Printer. STOQ has no packing slip designer of its own. ### Can I show the deposit and balance amounts on the slip? Yes. Turn on **Show payment details & savings in cart** under Advanced → Cart. It adds the payment breakdown (amount due now vs. remaining) for deposit or partial-payment offers. See [Set up payment for preorders](https://help.stoqapp.com/preorders/set-up-payment-for-preorders/). ### Will the shipping date update on the slip if I change the offer's date later? No. The details are written once, at checkout, from the offer's settings at that moment. Changing the offer's date afterward only affects new orders; existing orders keep the date that was shown when they were placed. ### Can I add my own custom line, like a warehouse note? Yes. Use **Add custom cart attribute** under Advanced → Cart to write a single freeform message (optionally using the available variables for offer name, date, payment, discount, and so on). It prints wherever your packing slip template prints line-item details. ### I sell to B2B customers, is anything different? For B2B orders, STOQ also adds a **"Purchase type: Preorder"** line automatically, which prints on the packing slip the same way as the other details. If the offer has a custom cart attribute, your text prints in its place. ## Related guides - [Preorder advanced settings](https://help.stoqapp.com/preorders/preorder-advanced-settings/): The cart details (fulfillment timeline, payment, custom message) that appear on packing slips. - [Set up payment for preorders](https://help.stoqapp.com/preorders/set-up-payment-for-preorders/): Configure deposits and partial payments, the amounts shown in the payment line. - [Use preorders with a 3PL](https://help.stoqapp.com/preorders/preorders-with-3pl-fulfillment/): How order and line-item details reach a third-party fulfillment system. - [Let customers cancel their preorders](https://help.stoqapp.com/preorders/preorder-cancellation/): What happens to an order and its details when a preorder is cancelled.
