# 📫 National Shipping with any Carrier

## Use Slerp with any 3PL to organise orders, export data, and hand parcels to your preferred shipping provider.

### How it works

Slerp helps you **organise** orders, print labels, and create CSV files.  
Your chosen carrier is responsible for:

- Collecting parcels.
- Transporting them.
- Handling delays, damages, or lost parcels.

### Step 1 – Set up your account with the carrier

Before you change anything in Slerp:

1. Choose your carrier and open an account with them.
2. Get their: 
     - **Rates** (by weight, size, or zone).
     - **Cut‑off times** and collection schedule.
     - **Label and CSV requirements** (format, fields, etc.).
3. Decide what you will **charge customers**: 
     - You may pass on the full carrier fee.
     - Or charge a **fixed delivery fee** and absorb any difference.
     - Keep your pricing simple and clearly explained at checkout.

### Step 2 – Coordinate collection and fulfilment times

Agree with your carrier:

- What time they will collect parcels.
- Which days they collect (Mon–Fri, weekends, bank holidays).

Then align your Slerp **fulfilment windows** and **cut‑off times** with this schedule so you have enough time to:

- Prepare products.
- Pack safely.
- Label boxes.
- Hand over to the driver.

You can generate a report of **orders with a fulfilment date of tomorrow** from your Slerp Controls. This is useful to plan production and to upload details to your carrier if required.

### Step 3 – Label your orders

You need a simple labelling process so parcels can be scanned and reach the right customer.

- **Hardware:**  
  Use a label printer that works with your carrier’s labels (check size and format).
- **Data source:**  
  From Slerp Controls, you can download and print **order details** (customer name, address, order ID, etc.).
- **[Composer](https://support.slerp.com/knowledge/composer-3pl-export?hsLang=en)(optional):**  
  Slerp’s **Composer** tool can: 
    - Generate **custom CSV files** in your carrier’s exact format.
    - Help manage orders, fulfilment, and printing labels.

If you don’t yet use Composer, speak to your Account Manager or Support to set this up.

To know more about Slerp Composer, see:

### Step 4 – Export and upload orders

Depending on your setup:

1. From Slerp / Composer, export the orders you plan to ship on a given day.
2. Upload the CSV into your carrier portal (or use their API if you have your own integration).
3. Print and attach the labels generated by the carrier.
4. Keep tracking numbers if provided — you can add these to your own systems or customer communications.

### Step 5 – Handling issues

Because delivery is handled by your carrier:

- If a parcel is late, damaged, or missing, you’ll need to **contact the carrier directly**.
- Slerp Support can help check: 
    - Whether the order details exported correctly.
    - Whether fulfilment times and dates in Slerp match what you expected.
