Refer-a-Friend Program

What This Recipe Does

This recipe creates a referral program designed for your existing customers. Each customer gets a unique referral link. When they share it with a friend and that friend makes a purchase, the referrer earns a flat $10 reward.

Unlike a traditional affiliate program, this is framed as a customer loyalty feature. The language, structure, and reward model are designed around everyday customers sharing with people they know, not professional marketers running campaigns. Customers think in dollar amounts, not percentages, so the reward is a simple flat rate.

Who It’s For

• Store owners who want organic growth through customer word-of-mouth, with a structured incentive to encourage sharing
• Brands building community that want to reward loyal customers for bringing in new buyers
• Subscription and membership businesses looking for a low-cost, automated way to acquire new customers through existing ones

How It Works

When you apply this recipe, Siren creates a referral program that your customers can join. You set up a registration form (Siren provides tools for this) where customers sign up and receive a unique referral link.

When a customer shares their link and a friend clicks it, Siren records a referred site visit and binds that friend to the referrer. If the friend goes on to make a purchase, the referrer earns a $10 reward.

The reward is a fixed amount stored internally as 1000 cents. It does not change based on what the friend buys. Whether the friend spends $15 or $150, the referrer earns $10.

If a friend clicks referral links from two different customers before purchasing, the most recent referral gets credit. This keeps the program straightforward for customers who do not need to think about attribution rules.

The referral reward is tracked as a commission in Siren, which means you can review, approve, and pay it out through whatever process works for your business. Some stores issue store credit, others send direct payments. Siren tracks the earnings and leaves the fulfillment method up to you.

Transaction compilers include line items only, so the reward triggers on actual product purchases. Shipping, taxes, and fees are excluded from the trigger conditions.
