---

### 🧭 Step-by-Step Instructions

1. **Sign In**
   Log in to your [TUNL account](https://app.tunl.to/) using your credentials.

2. **Go to Settings → Account**
   From the left-hand menu, click **“Settings”** to expand it, then click **“Account.”** This opens the [Account Settings](https://app.tunl.to/settings/account/billing/details) page.

3. **Open the Account Settings tab**
   At the top of the page, click the **“Account Settings”** tab (next to Account Overview, Manage Users and Impersonate Merchant).

   This page is split into two sections, each with its own **Save Changes** button:
   * **Merchant details** (used on shipping labels and customs paperwork)
   * **Billing Information** (used on your TUNL invoices and for billing)

4. **Edit Your Details**
   Click into any field you'd like to change.

   **Merchant details or Billing Information**
   * Company name
   * Contact email
   * Contact phone
   * Exporter's code (or ID number)
   * ID number (or Exporter's code): please provide at least one of the two. Both is fine.
   - Company / Billing name
   - Billing email
   - Contact number
   - VAT / Tax number
   - Address line 1 and Address line 2
   - City
   - State/Province
   - Zip/Postal code
   - Country

5. **Save Your Changes**
   Once you've made your updates, click the **“Save Changes”** button at the bottom of the section you edited. The button stays greyed out until you change something. If you've updated both sections, save each one separately.

   ✅ Your business profile is now current and ready to use for all new bookings.

| 💡 Need to change your pickup address? Go to Settings → Shipping → Ship From Location, where you can edit or add pickup addresses in your address book.

💡 Want to update your billing emails or payment card? Billing emails are shown on the Account Overview tab (click “Manage billing details”), and your saved card sits under Payment Method at the bottom of the Account Settings tab. One card can be stored at a time.
