# How to Fulfill 4PL Orders  for US in the SPL TikTok Shop App

# 4PL Order Fulfillment (US) – SPL TikTok Shop Connector
The **4PL (Fourth-Party Logistics) Fulfillment** feature in the SPL TikTok Shop Connector allows US merchants to ship TikTok Shop orders using TikTok-supported logistics carriers (such as USPS). This method automatically syncs tracking details between TikTok and Shopify and reduces manual shipping work.
This guide explains how to **identify, prepare, and ship 4PL orders** from the SPL app.

## Where to Find 4PL Orders
1. Open **Shopify Admin**.
2. Go to **Apps → TikTok Shop – SPL**.
3. Click **Orders** from the left sidebar.
You will see order tabs such as:
* **All**
* **Unfulfilled**
* **Awaiting Collection**
* **In Transit**
* **Delivered**
* **Cancelled**

When an order is eligible for fulfillment, the **“Fulfill on TikTok”** button becomes active.

## Steps to Fulfill a 4PL Order (US)
### Step 1 – Click “Fulfill on TikTok”
* Locate the order in the **Orders** list.
* Click **Fulfill on TikTok** in the **Tracking Info** column.
* A popup titled **TikTok Shipping Fulfillment (4PL)** will open.

### Step 2 – Select Items to Fulfill
Inside the popup:
* Under **Create New Package**, you will see a list of products.
* Tick the checkboxes for the items you want to ship.
* Multiple quantities of the same SKU may appear — ensure correct selection.
> Tip: Always verify SKUs and quantities before proceeding.

### Step 3 – Enter Package Details
Under **Package Details**, provide shipping measurements:
**Weight**
* Enter the total package weight.
* Select the correct unit (usually **POUND** in the US).
**Dimensions**
* **L (Length)**
* **W (Width)**
* **H (Height)**
* Unit is typically **INCH**.
Accurate measurements are important to avoid shipping price errors or carrier rejection.


### Step 4 – Select Shipping Service
In the **Shipping Service** dropdown:
* Choose a TikTok-supported US carrier.
* Example: **USPS Ground Advantage – USPS (USD $3.43)**.
The available services depend on TikTok Seller Center carrier configuration and warehouse location.

### Step 5 – Create Package
* Click **Create Package**.
* The SPL app will:
    * Send shipment data to TikTok.
    * Generate a shipping label.
    * Sync tracking automatically.

## Important Notes for US Merchants
* Ensure **Warehouse Address** is correctly set in TikTok Seller Center.
* Use **accurate weight & dimensions** to avoid carrier issues.
* If the **Fulfill on TikTok** button is disabled:
    * Order might be unpaid.
    * Package status is not `TO_FULFILL`.
    * Carrier service not configured.

## When to Use 4PL Fulfillment
Use 4PL if you want:
* Automatic label generation.
* Automatic tracking sync.
* Reduced manual shipping effort.
* Integration with TikTok-approved US carriers.

By following these steps, US merchants can efficiently ship TikTok Shop orders through the SPL TikTok Shop Connector using the **4PL Fulfillment** workflow.

## Alternative Method: Fulfill 4PL Orders Directly from Shopify Admin
You can also fulfill 4PL TikTok orders directly inside your **Shopify Admin**, without opening the SPL app dashboard.
### How It Works
1. Go to **Shopify Admin → Orders**.
2. Open the TikTok order you want to process.
3. Scroll down to the **Blocks** section.
4. Click the **SPL TikTok Order Fulfillment** block.
5. Click **Create TikTok Shipping Label**.
6. Select the package and confirm fulfillment.

Once confirmed, the system sends fulfillment details to TikTok, generates the shipping label, and automatically syncs tracking information.
This method is ideal for merchants who manage all orders directly from Shopify and prefer not to switch between apps.
