# Preorders with the SplitOrder app

> Stop preorder units being counted twice when the SplitOrder app splits a mixed order.

Use this guide if you use the third-party **SplitOrder** app to split mixed orders and your preorder **Units sold** numbers look too high. By the end, STOQ will recognize the orders SplitOrder creates and count each preorder unit once.

## Before you begin

| Requirement | Detail |
|---|---|
| The SplitOrder app | This setting only matters if you use the third-party SplitOrder app. If you don't, leave it off |
| New orders only | Turning this on changes how future orders are counted. Reports for orders already recorded aren't recalculated |

> **Warning**
>
> Splitting orders with a third-party app isn't recommended. STOQ can do it natively with **Move preorder items to a separate order**, which doesn't cause double-counting. See [Separate orders for mixed carts](https://help.stoqapp.com/preorders/separate-orders-for-mixed-preorders/). Use this integration only if you're staying on SplitOrder.

## Why units get counted twice

When a customer buys a preorder item and an in-stock item together, SplitOrder moves items into a second order. That new order still carries the preorder offer on its line items, so without this setting STOQ records the preorder twice: once on the original order and again on the order SplitOrder created. Your **Units sold** is inflated as a result.

With the setting on, STOQ identifies the order SplitOrder created and skips it, so only the original order counts.

## Set it up

On a phone, this menu is collapsed. In the **Shopify mobile app**, tap the **STOQ** logo at the top of the screen to open it, then choose the section named below. There is no hamburger icon. See [Finding the STOQ menu](https://help.stoqapp.com/general/getting-started-with-stoq/#finding-the-stoq-menu).

1. **Open the Integrations page**

   1. In the left menu bar of the STOQ app, click **Preorders**.
   2. Click the **Settings** tab.
   3. Open the **Integrations** sub-tab.
   4. Click **See integrations**, then under **Other** click **Set up** on the **SplitOrder** card to expand it.

2. **Turn on the integration**

   Turn on **SplitOrder integration**. It's off by default.

## Check your setup

Place a test order containing one preorder item and one in-stock item, and let SplitOrder split it. Then go to **Reports → Preorders** and confirm the preorder item is counted once, not twice.

## Troubleshooting

- **If units are still counted twice**: confirm the setting is on, then check whether the double-counted orders were created before you turned it on. Existing reporting isn't recalculated.
- **If preorders stop appearing in reports entirely**: check that you actually use SplitOrder. If the app isn't splitting your orders, leave this setting off.

## FAQ

### Does this fix reports for orders already placed?

No. It changes how orders are counted from the moment you turn it on. Orders already recorded keep their existing numbers.

### Does this change anything for customers?

No. It only affects how STOQ counts preorder units in your reports. Customers see no difference at checkout, and no emails or payments change.

### Should I use SplitOrder or STOQ's own split feature?

STOQ's built-in **Move preorder items to a separate order** is the better option, because it splits orders natively without double-counting. See [Separate orders for mixed carts](https://help.stoqapp.com/preorders/separate-orders-for-mixed-preorders/).

### Can I turn it on if I don't use SplitOrder?

There's no reason to. It only affects orders the SplitOrder app creates, so it does nothing on its own. Leave it off.
