### 1. W-9 Form

This feature allows you to easily collect your U.S. affiliates' **W-9 forms** for tax filing purposes. Affiliates will get to confirm if they're U.S. residents first to determine if they must fill in this form.

You will first need to enable it by clicking this button.

### 2. Multi sign-up pages

This is what allows you to have different sign-up pages for different affiliate programs at the same time! After enabling this feature, each program will show up with a different link in the **Programs** tab. Also, it unhides the option to select a different program for invited affiliates to join **MLM**.

### **3. Track Pending Referral Orders**

This is where you can choose to **Record Pending Orders** as successful referrals even though they weren't paid for or marked as paid on Shopify.

{% hint style="info" %}
If this isn't enabled, we'll keep tracking only **Paid** orders by default.
{% endhint %}

### 4. Report data (optional but important)&#x20;

This is where you can choose which sale data should be used and displayed to your affiliates regarding commission calculation - your **Total Sales on Shopify** or **Commissionable Sales in BixGrow**.

{% hint style="info" %}
The Commissionable Sales value is usually less than of Shopify's Total Sales since it's often set up as Total Sales minus the fees.
